T and B cell-deficient rag1−/− mutant zebrafish develop protective immunity mediated by trained immunity. In mammals, trained immune responses can be induced by Toll-like receptor (TLR) ligands. This study evaluated protective trained immunity in rag1−/− zebrafish through exposure to TLR ligands (beta glucan, R848, poly I:C), RE33® (a live-attenuated Edwardsiella ictaluri vaccine), or combinations thereof, followed by wild-type E. ictaluri challenge one month later. Survival analyses revealed that all TLR ligands and vaccine treatments provided significantly higher protection than the control, with beta glucan inducing significantly greater protection than RE33®, while R848 and poly I:C were equivalent to the vaccine. Survivals for the treatments were beta glucan 70%, beta glucan + RE33® 60%, R848 + RE33® 54%, poly I:C + RE33® 50%, R848 49%, poly I:C 32%, RE33® 24%, and control 0%. Gene expression analysis of kidney and liver tissues post challenge revealed that beta glucan training elicited early and strong increased expressions of nklb (5536 fold @ 6 hpi), nkld (147 fold @ 12 hpi), and ifng (575 fold @ 12 hpi) in the kidney, and ifng (1369 fold @ 6 hpi), nkla (250 fold @ 6 hpi), nklb (734 fold @ 6 hpi), nklc (2135 fold @ 6 hpi) and nkld (589 fold @ 6 hpi) in the liver. Principal component analysis (PCA) revealed that early kidney gene expressions at 6–12 h post secondary infection (nkla @ 12 hpi, nklb @ 6 and 12 hpi, nklc @ 6 and 12 hpi, nkld @ 6 and 12 hpi, ifng @ 6 and 12 hpi, t-bet @ 6, 12 and 48 hpi, and nitr9 @24 hpi) in the kidney and liver (nkla, nklb, nklc, nkld, ifng, t-bet and nitr9 @ 6 hpi) were associated with the highest survival. This study highlights that TLR ligand-induced trained immunity boosts innate immunity and survival, with NK cell subpopulations in kidney and liver tissues responding differently to mediate protective responses.

Various types of wheat bread are present in the Serbian market: white, brown, whole-wheat, wheat/rye, buckwheat/wheat, half-white and corn/ /wheat bread. This research included the quantification of the content of total fiber, fiber fractions, and microelements (manganese, copper, iron and zinc) in order to check whether the breads on the market contain the amounts that are proven beneficial for health. The aim was also to determine the contribution of these nutrients through the consumption of bread to the recommended daily intake. The results show that the bread from the Serbian market contains a large amount of arabinoxylan (1.2–2.6 g 100 g-1) and that wheat/rye, brown and whole wheat bread are sources of dietary fiber (4.0–4.6 g 100 g-1). Also, an important result is that all types of bread except white, contain more than 15 % of dietary reference values for copper and manganese. The intake of total fiber (+ 100 %), arabinoxylan (+ 117 %), copper (+ 118 %), and manganese (+ 85 %) increases by replacing white bread with whole wheat bread, therefore it is of great interest to raise awareness among consumers about the beneficial foods that should be included in the diet. Methods applied in this research showed acceptable precision and accuracy and also proved to be quite simple for routine analysis work. [ABSTRACT FROM AUTHOR]

Barley serves as a crucial feed crop and is also utilized for baking, malting, and brewing purposes. In India, the consistent demand for malting-type barley has not been met due to the lack of suitable varieties. This study evaluated 136 barley germplasm accessions for diversity in biochemical and agro-morphological traits. The accessions were grown in Augmented Block Design and biochemical estimations were carried out using official and standard methods. The accessions exhibited substantial biochemical diversity with protein content (PC) ranging from 8.6 to 17.4%, starch content (SC) from 32.4 to 60.3%, amylose content (AC) from 13.3 to 19.3%, β-glucan content (βgC) from 1.31 to 6.06%, and total phenol content (TPC) from 8.6 to 17.4%. The agro-morphological traits also displayed considerable variation, with days to spike emergence (DSE) ranging from 74 to 124 days, days to physiological maturity (DPM) from 119 to 147 days, plant height (PH) from 82 to 165 cm, spike length (SL) from 5 to 11 cm, spikelet triplet groups (STG) per spike from 13 to 35, grain number per spike (GNS) from 15 to 71, hundred-grain weight (HGW) from 2 to 6.7 grams, and grain yield per meter row (GY) from 13.7 to 236.3 grams. Multivariate analyses, including the Mantel test, Pearson’s correlation, principal component analysis (PCA), and hierarchical cluster analysis (HCA), were conducted. No significant correlation was observed between biochemical and agro-morphological traits. However, significant positive correlations were found between SC and AC (r = 0.48) and βgC with PC (r = 0.2). Significant negative correlations were observed between SC and PC (r = −0.41) and AC with PC (r = −0.4). Highly significant positive correlations were observed between DSE and DPM (r = 0.55), GY and PH (r = 0.29), PH and DPM (r = 0.2), and HGW and SL (r = 0.25). The GWL was significantly positively correlated with βgC (r = 0.257) and significantly negatively correlated with TPC (r = −0.235). Apart from Grain Width to Length Ratio (GWL), no other agro-morphological trait was significantly correlated with any biochemical trait. Various accessions suitable for malting, human food, and cattle feed applications were identified.

Background & objectives: Amphotericin B, Allopurinol, Glucantime and Beta-Glucan are the main drugs currently used for the treatment of cutaneous leishmaniasis. In present study, we evaluated the effect of medical leeches on BALB/c mice models infected with Leishmania parasites. Methods: To create animal models of leishmaniasis, BALB/c mice were inoculated with the standard Leishmania major strain MRHO / IR / 75 / ER. Treatment was performed through blood sampling with leeches. We used medical leech (Hirudo medicinalis) species. This leech is a European medicinal leech, one of several species known used as medicinal leech. Twenty-two mice infected with Leishmania major were used for the tests. The studied mice were divided into two groups which were named with letters L and D. The duration of blood sampling was 25 min for initial treatment, 20 min for the 2nd blood sampling and 15 min for the third times and onwards. Meglumine antimoniate (Glucantime) is a pentavalent antimony (SbV) that is recommended by the World Health Organization as a golden standard treatment for all kinds of leishmaniasis, but many side effects are still reported. Criteria for anti-leishmania assessment of leech were including: leech saliva has an anti-leishmania effect by acting on the purin pathway. Leech saliva prevents growth and multiplication of Leishmania by a mechanism of action similar to Glucantim (breaking ATP). Results: The duration of leech treatment in BALB/c mice infected with L. major parasites was about 6-8 weeks. Out of the 22 leishmaniasis mice models that underwent treatment, 13 survived until the end of the treatment duration. The recovery rate was about 56%; lesions improved in five out of the 13 surviving mice models. Paired t-test showed a significant difference between the mean wound size at the beginning of treatment and the 8th week of treatment (PV

The immunotherapy for gastrointestinal tumors, as a significant research direction in the field of oncology treatment in recent years, has garnered extensive attention due to its potential therapeutic efficacy and promising clinical application prospects. Recent advances in immunotherapy notwithstanding, challenges persist, such as side effects, the complexity of the tumor immune microenvironment, variable patient responses, and drug resistance. Consequently, there is a pressing need to explore novel adjunctive therapeutic modalities. b-glucan, an immunomodulatory agent, has exhibited promising anti-tumor efficacy in preclinical studies involving colorectal cancer, pancreatic cancer, and gastric cancer, while also mitigating the adverse reactions associated with chemotherapy and enhancing patients' quality of life. However, further clinical and fundamental research is warranted to comprehensively evaluate its therapeutic potential and underlying biological mechanisms. In the future, b-glucan holds promise as an adjunctive treatment for gastrointestinal tumors, potentially bringing significant benefits to patients. [ABSTRACT FROM AUTHOR]

Background: This exploratory case-control study is to evaluate the effects of supplementation of Aureobasidium pullulans-N-163 strain produced 1,3–1,− 6 beta glucan in young patients with Duchenne muscular dystrophy (DMD). Methods: Twenty-seven male subjects aged 5–19 years with DMD were included, nine in the control arm and 18 in the treatment arm to receive N-163 beta glucan along with conventional therapies for 45 days. While performing the analysis, steroid usage was also taken into consideration, those not administered steroids (Steroid -ve) (Control, n = 5; treatment, n = 9), those administered steroids (Steroid +ve) (Control, n = 4; treatment, n = 9). Results: IL-6 showed a significant decrease in the treatment groups, especially the N-163 Steroid -ve group. IL-13 decreased in both treatment groups and TGF-β levels showed a significant decrease in the treatment groups, especially the N-163 Steroid –ve group, (p

Since the Bronze Age, oat (Avena sativa L.) has been used mainly as an animal feed. Currently, it is in high demand for human consumption because of its nutritional properties, which improve health and wellbeing. Oat is a good source of protein, carbohydrates, lipid, minerals, vitamins and phenolic compounds. However, quality traits are usually polygenic and subjected to non-heritable factors, making quality improvement difficult. Several conventional breeding approaches such as pure line selection, pedigree selection, mutagenesis, wide crosses and polyploidy have been extensively used to develop new and improved oat varieties, commonly for forage purposes. Molecular approaches such as use of molecular markers, QTL mapping, genome-wide association studies, genetic engineering, genomic selection and speed breeding are being utilised to identify traits/genes of interest, produce plants carrying the desired agronomic and climatic resilience traits, and accelerate genetic gain. There has been minimal focus on nutrient enrichment and the development of high-quality, enriched oat genetic resources. Herein, we address and compile much-needed, up-to-date information on comparative analysis of oat nutritional and phytochemical properties with those of other cereals. We also consider the importance and involvement of conventional breeding in the modern approaches. This updated information provides guidance for oat breeders to develop nutrient-enriched varieties and points to future prospects towards oat quality improvement. Good health, zero hunger and conservation of diversity are three major goals for sustainability in agriculture agriculture. Oat nutritional profiling, health benefits, and conventional breeding and biotechnological research are discussed in terms of improvement of different nutraceutical traits. This review could guide research into enhancing nutraceutical properties of oat. [ABSTRACT FROM AUTHOR]

Gut microbiota has been described as a new 'organ' that interferes with host physiology by its metabolites produced from the utilization and biotransformation of undigested food components. Fu Ling (FL), the sclerotia of fungi Wolfiporia cocos, contains β-glucan, which is a known natural polysaccharide with strong medicinal efficacy. This study endeavors to evaluate the fermentability of FL and polysaccharides extracted from its sclerotia. An in vitro fermentation of structurally characterized FL and its β-glucan by human fecal microbiota was conducted. Total bacterial count, pH change, short-chain fatty acid profile and microbiota profile were assessed post-fermentation. FL containing over 70% of β-(1 → 3) and (1 → 6)-glucans with a low degree of branching of 0.24 could enhance acetic acid (a major microbial metabolite) production. Both FL and its extracted β-glucan had similar modulation on microbial composition. They enriched Phascolarctobacterium faecium, Bacteroides dorei and Parabacteroides distasonis, all of which are shown to possess anti-inflammatory effects. FL polysaccharide can be utilized as a natural whole food for its potential health benefits to human gut bacteria. [ABSTRACT FROM AUTHOR]

The aim of the study was to evaluate the efficacy of a nutritional supplement containing a combination of Betox-93® beta-1.3/1.6-glucan 100 mg, ResistAid™ arabinogalactan 166 mg, zinc 7 mg and selenium 50 mcg, in patients 10 years of age and older on the frequency of acute upper respiratory tract infections (AURTIs) and the dynamics of their symptoms (severity). Material and methods. 242 patients with at least 3 AURTIs in the past 6 months were followed up for a period of 8 weeks during which they took the nutritional supplement at a dosage according to the product's prescription. The number of AURTIs episodes during the previous 24 weeks of observation, additionaly for the previous 8 weeks, the observation period of 8 weeks and the same 8 weeks as the observation period but the previous year were recorded. A general practitioner ambulatory assessed the intensity (severity) and dynamics of the symptoms of AURTIs during the observation period. Data are collected between September 15, 2022 and January 31, 2023. Results. Patients reported a median of 4 (IQR 3-4) episodes of AURTIs in the previous 24 weeks, of which 1 (IQR 1-2) in the last 8 weeks. The episodes of AURTIs had a median of 1 (IQR 0-1) during the followup period, which is significantly lower than the previous 8 weeks (p < 0.001). A median of 2 (IQR 2-3) AURTIs episodes were reported for the same 8 week period in the previous year, which was significantly more then the follow-up period (p < 0.001). An episode of AURTI was recorded during the follow-up period in 155 patients (64.0%), and in 13 (5.4%) also a second such episode. As expected, the assessed 10 symptoms of AURTIs showed significant improvement between days 1 and 5 in both reported frequency and severity. When evaluating the dynamics of the symptoms during the second episode of AURTI, a significant improvement was proved only in some of them, due to the small number of cases with infection. Conclusion. The results showed that patients' health is improved after supplementation with Betox-93® beta-1.3/1.6-glucan, ResistAid™ arabinogalactan, zinc and selenium dietary supplement. On one hand, the number of AURTI episodes for the observation period was significantly less than the previous 8 weeks, and on the other hand, they are significantly less than the same time interval in the previous year. In addition, a significant improvement in the presence and intensity of 10 recorded symptoms between days 1 and 5 was found for the first episode of AURTI. [ABSTRACT FROM AUTHOR]

In the present study, we reviewed the efficacy of traditional herbal formulas on human immunity. A literature survey was performed in PubMed, UpToDate, Proquest Central Databases of Kırıkkale University, Google and Google Scholar databases from the internet. Search key words were "immune", "immune system", "herbal", "Pelargonium Sidoides", "Echinacea Purpurea", "Sambucus Nigra", "Beta Glucan", "Vitamin C", "Zinc". The immune system is a natural self-defense mechanism made up of cells that assist the body in distinguishing between self and non-self-molecules. All immune system components must be regularly modified in order to keep the body defenses up against the ever-evolving microbes that are constantly looking for new ways to attack the host. A Chinese herbal formulation is a combination of several herbs. The practitioner begins with one or two major substances that are intended to treat the ailment. The reproducibility of the efficacy of herbal medicines is dependent on the consistency of the quality of each unique raw herb. Pelargonium Sidoides, Echinacea Purpurea, Sambucus Nigra, Beta Glucan, Vitamin C, and Zinc are some herbal treatments utilized for their benefits on human immunity. Herbal remedies are undoubtedly valuable in boosting impaired immune function, particularly where damage has occurred due to malnutrition, chronic disease or previous infections. At present, however, an invincible immune system remains firmly in the realm of fantasy. [ABSTRACT FROM AUTHOR]

ABSTRACT Oyster mushrooms are widely known as having high beta glucan content. Beta glucan is a water insoluble fiber that indicates an immunomodulator with increasing the activity of NK cells in the bloodstream which provides immune effect. Oyster mushroom nuggets are processed oyster mushrooms that can be proven containing the highest beta glucans. This study aims to observe the immunostimulant potential of oyster mushroom nuggets in BALB/c mice by analyzing its white blood cell profile, spleen and liver histopathology. The research method is conducted through orbital sinus of the rat's eye using a microhematocrit to count total leukocytes, lymphocytes, and granulocytes with the Delayed Type Hypersensitivity test. The 18mg/kg body weight oyster mushroom nugget can increase lymphocytes cells 7.2 ± 1.22 103/μl. It is significantly different from control group. Immunostimulatory activity alsowas proven with the widening of the white pulp of the spleen with the growth of young lymphocytes after being given oyster mushroom nuggets of 18 mg/kg body weight.

Aim: In this study, it was aimed to investigate the effects of beta glucan (BG) on the experimental colitis model created by using trinitrobenzene sulfonic acid (TNBS). Material and Methods: Thirty-two Wistar Albino rats were divided equally into four groups as sham control, TNBS, TNBS-BG3, and TNBS-BG10 groups. While saline was administrated to sham group, TNBS was administered intrarectally to the TNBS groups under anesthesia. BG was administered at a dose of 100 mg/kg by oral gavage, intragastrically, for 3 days (TNBS+3) to the TNBS-BG3 group and for 10 days (7+TNBS+3) to the TNBS-BG10 group. At the end of the study, macroscopic, histological and biochemical tests were applied to the colon tissues taken. Results: It was determined by histopathological scoring and biochemical results that BG administration caused positive effects on colon damage due to colitis. Malondialdehyde level and myeloperoxidase activity were found to be significantly higher in the TNBS group compared to the other groups (p=0.003 and p

The oyster mushroom (Pleurotus species) is a popular and widely cultivated edible mushroom that can be found worldwide, including in Malaysia. However, its local production is unable to fulfil the market demand, partly due to the limited availability of rubber wood sawdust (RWS) as the conventional cultivation substrate. Furthermore, the palm oil industry in Malaysia generates large volumes of organic by-products that have caused environmental concerns. Therefore, the potential utilisation of oil palm waste-based substrates in order to develop a substitute RWS for Pleurotus ostreatus mushroom production is evaluated in this study, based on their agronomic performance and nutritional properties. Empty fruit bunches (EFBs), oil palm fronds (OPFs), and oil palm trunks (OPTs) were used to formulate the substrates. The control used was 100% RWS. Generally, 100% EFB showed a better agronomic performance, and mushroom growth was 1.9 times faster compared to the control, with a comparable mushroom yield. The crude protein and beta glucan content of mushrooms grown on oil palm by-product-formulated substrates were significantly higher than those grown using the control. Additionally, the number of fruiting bodies, crude protein, and beta glucan content of the mushrooms were positively correlated with potassium in the substrate. Therefore, 100% EFB could be used as a potential substitute for RWS for the cultivation and production of P. ostreatus. [ABSTRACT FROM AUTHOR]

Beta glucan exposure induced trained immunity in channel catfish that conferred long-term protection against Edwardsiella ictaluri and Edwardsiella piscicida infections one month post exposure. Flow cytometric analyses demonstrated that isolated macrophages and neutrophils phagocytosed higher amounts of E. ictaluri and E. piscicida. Beta glucan induced changes in the distribution of histone modifications in the monomethylation and trimethylation of H3K4 and modifications in the acetylation and trimethylation of H3K27. KEGG pathway analyses revealed that these modifications affected expressions of genes controlling phagocytosis, phagosome functions and enhanced immune cell signaling. These analyses correlate the histone modifications with gene functions and to the observed enhanced phagocytosis and to the increased survival following bacterial challenge in channel catfish. These data suggest the chromatin reconfiguration that directs trained immunity as demonstrated in mammals also occurs in channel catfish. Understanding the mechanisms underlying trained immunity can help us design prophylactic and non-antibiotic based therapies and develop broad-based vaccines to limit bacterial disease outbreaks in catfish production.

Introduction: As a supplement, beta–glucan has various therapeutic healing effects generated by the immune cells. It has been scientifically approved and proven to be a biological defense modifier. The aim of this study was to investigate the effects of beta–glucan on treatments administered in an acute otitis media model Objectives: This study investigated the effect of beta–glucan on the treatment of acute otitis media in an acute otitis media -induced animal model. Efficacy was evaluated both immunologically and histologically. Methods: The study sample comprised 35 adult rats, randomly separated into 5 groups of 7: Group 1 (control), Group 2 (acute otitis media, no treatment), Group 3 (acute otitis media + antibiotic), Group 4 (acute otitis media + beta–glucan) and Group 5 (acute otitis media + beta–glucan + antibiotic). Analyses were made of the histopathology and immunology examination results in respect of thickening of the tympanic membrane, epithelium damage, inflammation, and sclerosis. In all groups the serum levels of TNF-α, IL-4, IL-6 and IL-1β were evaluated. Results: All serum cytokine levels were significantly lower in the beta–glucan and antibiotic-treated groups compared to the acute otitis media Group. Significant differences in tympanic membrane thickness, inflammation, epithelium damage, and sclerosis values were observed between the acute otitis media + antibiotic and acute otitis media + beta–glucan Groups. According to these parameters, the values in aute otitis media + antibiotic + beta–glucan Group were markedly lower than those of the other groups. There was a significant difference in the acute otitis media + antibiotic + beta–glucan Groups compared to acute otitis media Group (p < 0.001). Conclusions: Both antibiotic and beta–glucan treatment reduced acute otitis media signs of inflammations in an acute otitis media-induced rat model, decreasing histological damage and cytokine levels. Co-administration of antibiotic and beta–glucan led to a significant reduction in tympanic membrane thickness, inflammation, and epithelium damage. Antibiotic + beta–glucan treatment resulted in a greater decrease in tympanic membrane thickness, inflammation, and epithelium damage than in the other groups. From these results, it can be suggested that beta–glucan, in combination with antibiotics may provide an alternative for the treatment of acute otitis media.

The use of functional feeds for farmed fish is now regarded as a key factor in improving fish health and performance against infectious disease. However, the mechanisms by which these nutritional components modulate the immune response are not fully understood. The present study was undertaken to identify the suitability of both primary gut-associated lymphoid tissue (GALT) leucocyte cells and established rainbow trout cell lines as potential alternative methods to test functional feed ingredients prior to full fish feeding trials that can take months to complete. In addition to the primary GALT culture cells, the two rainbow cell lines RTS11 and RTgutGC which are from macrophage and gut epithelial cells, respectively. The cells were stimulated with a variety of pathogen associated molecular patterns (PAMPs) (PHA and Poly I:C) and recombinant rainbow trout IL-1β (rIL-1β), a proinflammatory cytokine, additionally two forms of β-glucan, a prebiotic commonly used aquafeeds were used as stimulants. From this, the suitability of cell models as a health screen for functional feeds was assessed. GALT leucocytes were deemed most effective to act as a health screen over the 4hr time point demonstrating responses to Poly I:C, PHA, and rIL-1β. RTS11 and RTgutGC also responded to the stimulants but did not give a strong T-cell response, most likely reflecting the nature of the cell type as opposed to the mixed cell populations from the primary GALT cell cultures. When stimulated with both forms of β-glucan, GALT leucocytes demonstrated a strong proinflammatory and T-cell response.

Bortezomib, selective inhibitor of the 26S proteasome, is used for treatment of some types of cancer and immunosuppressive therapies. B-1,3- (D)-glucan, a synthetic antioxidant is used complementary medical treatment for human. This study was conducted to investigate the effects of the antioxidant Beta-1,3-D glucan on rat pancreas treated with systemic bortezomib. In the study, 36 Sprague-Dawley adult male rats were divided into four groups: control (C), bortezomib (BZ), ß-1, 3-D-glucan (BD) and bortezomib + ß-1,3- (D) -glucan (BZ+BD). Each group was divided into two subgroups (48 or 72 hours), depending on the time of scarification. After experiments, immunohistochemical, stereological and histopathological changes in all rat pancreatic tissues were examined. It was determined increased degenerative, vacuolated serous acini cells and inflammatory cell infiltrations in the groups of BZ and BZ+BG. In immunohistochemical analysis, densities of insulin positive cells were decreased in the groups of BZ and BZ+BG. Furthermore, in stereological mean volume of serous acinus analysis, significantly increases were detected in the groups of BZ and BZ+BG (p<0.05). BZ treatment had the detrimental effects on pancreas tissues. Also, administration of BG was insufficient to prevent injury induced by BZ treatment in the pancreas tissues. [ABSTRACT FROM AUTHOR]

Diagnostic tests for fungi provide the mycological evidence to strengthen diagnosis of invasive fungal disease. Conventional microbiology and histopathology have their limitations. Recognizing this, there have been attempts at developing new methods to improve yield of diagnosing invasive fungal disease (IFD). The recent focus has been on non-culture-based antigen detection and molecular methods. The use of antigen detection of IFD through 1,3-β-D-glucan and galactomannan assay have been expanded, followed by development of lateral flow assays, and in combination with other diagnostic modalities to further increase diagnostic yield. The molecular diagnostic front has seen initiatives to standardize polymerase chain reaction methodologies to detect fungi and anti-fungal resistance, new platforms such as the T2Candida Biosystems and foray into fungal metagenomics. As these newer assays undergo stringent validation before incorporation into the diagnostic algorithm, the clinician needs to be mindful of their bedside utility as well as their limitation.

Wound management is one of the oldest and one of the most frequent therapeutic activities in medicine. Over the centuries there has been described and tested many therapeutic substances for the treatment of wounds with various effects. Due to the discovery of antibiotics, a wound management regime used to be limited only to a local application. Over years, it has been shown, that comprehensive therapy which uses only antibacterial preparations, also may contain some negative points (resistance of aggressive pathogens, toxicity, allergic reactions, etc.). According to studies, the best solution to this problem is a local application, using preparations that ensure the sterility of the affected parts of the skin, and the utilization of agents that are able to accelerate the granulation and lead to the healing process of the wound. Products that contain beta glucan combined with a gentle but effective antiseptics (chlorhexidine digluconate), or natural substance with antiseptic and also nourishment effect (honey), are very beneficial in wound management. A good penetration of active agents, the ability to moisturize defective tissues, and to make a protective film that hinder the intersection of impurities and decrease secondary contamination, are the benefits of a gel formulation, that is the most appropriate external form of application in veterinary practice that can improve and accelerate a successful healing process of wounds in animals.

The commonly used term of "clean label" refers to food products that do not contain additives (E numbers). Although there is not always a scientific reason for believing that additive-free products are healthier, clean label products are becoming more popular. The growing market for gluten-free foods represents an important target group of consumers, who could be interested in products meeting clean label standards. However, manufacturing gluten-free baked goods according to the clean label concept is extremely difficult, as gluten-free raw materials demonstrate poor baking properties. Additives are required to simulate the texturing properties of gluten, few of are suitable for clean label products. This paper discusses the possibility of replacing the hydrocolloids most commonly used in gluten-free baked goods with β-glucan, psyllium, or transglutaminase. [ABSTRACT FROM AUTHOR]

This study investigated the prevention and treatment of gastritis or /and gastric ulcer actions using white log mushroom (Lentinus squarrosulus, (Mont.). Methods: White wistar rats were induced with 100 % absolute alcohol to be effective for gastritis and /or ulceration within rats. The gastric lesions of white wistar rats were investigated and calculated the lesions of stomach areas under microscopic method. The results were calculated and a comparative study among white wistar rats. Ulcer prevention and ulcer healing properties were administrated though a dose of 250 mg/kg of L. squarrosulus extract and L. squarrosulus compared with 50 mg/kg of Ranetidine. Results: It was found that Lentinus squarrosulus, (Mont.) consisted of Beta-glucan was the active ingredient creating a healing effect. It showed a result of 100% healing effect in gastritis and/or ulcers in which it had similar healing effects between extracted solutions of white log mushroom (250 mg/kg body wt.) The healing activity also showed the equivalent effect compared to Ranetidine 150mg. Conclusions: Extracted solution of white log mushroom showed prevention and treatment efficacy in gastritis and/or ulcer are equivalent to Ranetidine 150 mg. A similar dose of 250 mg/kg of L. squarrosulus extract and L. squarrosulus snack can prevent and heal ulcers and is more effective than Ranetidine. [ABSTRACT FROM AUTHOR]

Three hundred Oreochromis niloticus were divided into five groups; the control fish (CNT) were fed a basal diet, beta glucan (βG) group was fed 0.5 g/kg−1 βG, atrazine (ATZ) group was exposed to 1/5 96‐hr LC50 (1.39 mg/L) ATZ, the (βG/ATZ) group was fed βG while being exposed to ATZ, and the (βG then ATZ) group was supplemented with βG for fifteen days before exposed to ATZ. ATZ exposure caused a decline in growth that was ameliorated by βG. ATZ reduced the levels of total and different types of leucocytes. Additionally, ATZ exposure caused reductions in total proteins, globulins, α 1‐globulin, α 2‐globulin, ɤ‐globulin, immunoglobulin M, lysozymes, superoxide dismutase, nitric oxide and catalase but increases in hepatic transaminases and malondialdehyde without any variations in albumin and β‐globulin. Exposure to ATZ also resulted in a rise in the mRNA level of IL‐8. In contrast, expression of IgM, SOD and CAT were decreased in the tilapias exposed to ATZ. Exposure to ATZ increases the susceptibility response to Aeromonas sobria challenge, as indicated by an increase in cumulative mortality post‐challenge. Supplementation with βG fifteen days before (βG then ATZ group), counteracted the adverse effects of ATZ on the immune, biochemical and antioxidants values, though only slight alleviation was observed with simultaneous treatment (βG/ATZ group). Our results established that ATZ has adverse impacts on immune responses, antioxidant equilibrium and its related genes. While, supplementation with βG before exposure to ATZ may be valuable for counteracting the possible damage caused by ATZ water pollution than its simultaneous treatment with ATZ.

Juvenile common carp Cyprinus carpio L. (5.52 ± 1.66 cm, TL) were fed on four diets containing either beta-glucan (MacroGard, 1 g kg −1), nucleotides (Optimûn, 0.2 g kg - 1), chitosan (deacetylated chitin ≥75% shrimp shells, 10 g kg −1) or a basal control diet for 35 days to test whether these so-called "immunostimulants" could affect eye fluke Diplostomum spp. infection success. The immunostimulants diets reduced the number of eye fluke infecting the eyes of C. carpio , with significantly higher infections in the control diet (4.78 ± 1.27) compared with the chitosan (2.08 ± 0.87), nucleotide (2.98 ± 1.01), and beta-glucan (1.41 ± 0.79) diets. To our knowledge, this is the first study to provide evidence that beta-glucan, nucleotides, and chitosan diets can aid against a Diplostomum infection and provides valuable preliminary knowledge on the use of immunostimulants to ameliorate parasitic infections. • The effect of dietary immunostimulants on eye fluke infection success was studied. • Nucleotide, beta-glucan, and chitosan can act as an aid against a Diplostomum infection. • Beta -glucan is more efficient at reducing the number of eye fluke in common carp.

The commonly used term of “clean label” refers to food products that do not contain additives (E numbers). Although there is not always a scientific reason for believing that additive-free products are healthier, clean label products are becoming more popular. The growing market for gluten-free foods represents an important target group of consumers, who could be interested in products meeting clean label standards. However, manufacturing gluten-free baked goods according to the clean label concept is extremely difficult, as gluten-free raw materials demonstrate poor baking properties. Additives are required to simulate the texturing properties of gluten, few of are suitable for clean label products. This paper discusses the possibility of replacing the hydrocolloids most commonly used in gluten-free baked goods with β-glucan, psyllium, or transglutaminase.

This 42-day study evaluated the effects of dietary supplementation with β-1,3-glucan (Aleta™) on the vaccination response to Newcastle disease virus (NDV), avian infectious bronchitis virus (IBV), and infectious bursal disease (IBD) in a non-challenged environment. This trial included 600 chicks (all vaccinated with IBD at the hatchery) which were assigned to 1 of 3 treatments: vaccination (NDV, IBV), no vaccination, or vaccination combined with feed supplemented with Aleta (100 g/MT of feed). The vaccination with Aleta treatment group showed a trend for improved FCR that was not statistically significant. Control birds that were not vaccinated for IBV had significantly lower IBV titers on day 21 compared to birds that were vaccinated (both with and without Aleta). Surprisingly, there was significant separation among treatment groups for NDV titer levels, especially on day 21, where birds vaccinated and supplemented with Aleta had significantly higher titer levels compared to vaccination alone or no vaccination at all. Critically, only 14% of the birds receiving the vaccine plus Aleta had titer levels below the critical titer threshold for immunity compared to 28% of the birds receiving the vaccine alone and 40% of the unvaccinated birds. This suggests that Aleta supplementation may help to improve the vaccination response by birds, especially for NDV. [ABSTRACT FROM AUTHOR]

Background and aims. One of the regenerative therapy modalities in Parkinson is using the beta glucan effect contained in Saccharomyces cerevisae. The purpose of this research is to identify the effect of reduction in alpha synuclein expression on the brain substantia nigra in Parkinson's rat model after given Saccharomyces cerevisae. Methods. This research applied true experimental design by in vivo with draft randomized post test only controlled group design. The sample was divided into five groups, each of them consisted of 5 rats, namely, negative control group, positive control, treatment 1, 2 and 3 (Rotenone + Saccharomyces cerevisae 18 mg/kgBB), 36 mg/kgBB, 72 mg/kgBB which is given for 30 days). Variables measured were the decreasing level of alpha synuclein. Results. There was a significant difference between positive control and negative control group (p = 0000) and treatment group (p = 0.000; 0.000; 0.000); the addition of Saccharomyces cerevisae in treatment 1, 2 and 3 (18mg/kgBB, 36mg/kg/BB, 72mg/kgBB) caused a significant difference compared with positive control group (p = 0.000; 0.000; 0.000); in treatment 1 (18 mg/kgBB) caused insignificant difference in the amount of alpha synuclein expression compared to the treatment 2 (36mg/kgBB) (p = 0.981), but it showed a significant difference in treatment 3 (72mg/kgBB) (p = 0000). Conclusion. The addition of Saccharomyces cerevisae is able to lower the alpha synuclein expression in Parkinson’s Wistar strain rat models significantly with maximum at the dose of 72 mg/kgBB.

Ear fungus (Auricularia auricula) contains soluble fiber (beta glucan) which is believed to have an effect of reducing cholesterol level. The aim of this study was to determine the effect of fungus infusion in reducing blood cholesterol. Methods: This study used the laboratory experimental method conducted in the pharmacology laboratory of Dr. Hasan Sadikin General Hospital Bandung. The subjects were 25 male Wistar rats which were randomly divided into 5 groups. The first group was given only distilled water as a negative control, the remaining groups were induced to be dyslipidemic and received fungus infusion with different doses of 18%, 36%, 72% and one group received no treatment. Results: The comparison of different doses showed all had the effect of reducing cholesterol levels compared to the positive control group (p

ackground: Dyslipidemia is a risk fastor in atherosclerosis. In the long run, it can cause complications such as coronary artery disease and stroke. Dyslipidemia can be halted by beta glucan, a soluble fiber found in some species of fungi. This study was conducted to find the effect of red ear fungi infusion in reducing blood triglyceride level and the concentration that will give optimal reduction of blood triglyceride level. Methods: This was an analytical study using experimental laboratoric method. The study conducted in 25 male Wistar rats sorted in 5 groups during the period of September to October 2012 in Pharmacology Laboratory of General Hospital Hasan Sadikin, Bandung. Results: The result showed that mean difference of all three treatment group, which is group 3, group 4, and group 5 (87.08, 90.40, and 82.70 respectively) showed significancy compared to the positive control (group 2). Out of the three group, group 4 with 36% infusion concentration has the lowest mean difference from all of the treatment groups. Conclusions: Red ear fungi infusion reduce blood triglyceride level and infusion with 36% concentration was the optimal concentration in reducing blood triglyceride level. A further study can be done to find concentration range in which the infusion reduce blood triglyceride level optimally.

We analyze the prognostic potential of (1 → 3)-β-D-glucan (BG) levels in predicting clinical outcomes in patients with invasive fungal infections, on a population undergoing 253 episodes (177 with positive and 76 with negative outcome). Using linear regression analysis, we assessed the prognostic potential of kinetically evaluated BG levels and we found an overall sensitivity and specificity of 68 and 82%, respectively. Moreover, using an interpretative algorithm based on two distinct cutoff values, we were able to predict the outcome in 84% of the studied population with a diagnostic accuracy of 82%.

This study determined the effect of a dried algae product containing beta-1,3-glucan on broiler performance and immunity during an Eimeria challenge. Heterotrophically grown Euglena gracilis, which contained ∼55% beta-1,3-glucan, was dried and milled for inclusion into a non-medicated starter diet. Two experiments were conducted to evaluate dietary treatments containing 0, 50, 100, 150, and 200 g/ton dried algae. In both experiments, male broilers were orally challenged on day 14 with a coccidial inoculum consisting of E. acervulina, E. maxima, and E. tenella. Fecal matter was collected 120–144 hours post-exposure to determine relative amounts of oocyte shedding and birds were sacrificed on day 20 for lesion scoring. Broiler performance was assessed on a weekly basis. In the first experiment, birds receiving dried algae at 50 and 200 g/ton showed a significant improvement in FCR compared to the infected control during the challenge period (days 14–20). In the second experiment, the dried algae treatment had no significant effect on FCR, but lesion scores were significantly reduced in the groups receiving 50, 150, and 200 g/ton dried algae relative to the infected control. In both experiments, the dried algae treatment did not significantly impact mortality or oocyte shedding. In the second experiment, staining of intestinal samples with fluorescently tagged antibodies demonstrated that dried algae at 100 g/ton increased the number of intestinal macrophages compared to the infected control. A significant and dose-dependent increase in intestinal MHC-II+ expression was also observed for birds fed dried algae, with an 8-fold increase observed in the 200 g/ton group relative to the infected control. Similarly, increased total immune cell density (measured by the mean fluorescence intensity of CD45+ cells) was also observed at 150 and 200 g/ton. Overall, these data suggest that dried algae rich in beta-1,3-glucan can help improve gut immunity and host protection, thereby reducing morbidity associated with coccidiosis. [ABSTRACT FROM AUTHOR]

The beneficial role of dietary fibre in human nutrition and effects of properties on fermented dairy products have led to a growing demand for the incorporation of novel fibre‐based fat replacers. The aim of the present work was to investigate the possibility of using inulin and oat‐based β‐glucan in Labneh cheese and to analyse the physico‐chemical, textural and sensory properties of the resulting product. The results showed that the textural and sensory properties of the cheese with addition of inulin increased at a 12% fat ratio. Overall, full‐fat and reduced‐fat Labneh cheeses were firmer and had better flavour than all the low‐fat cheeses. However, inulin and oat β‐glucan, as fermentable fibres, were also degraded as fermentable fibres to produce organic acids and had the potential for use as fat replacers in low‐fat dairy systems.

ackground and aims. One of many neurodegenerative diseases afflicting the elderly is Parkinson. Beta glucan from Saccharomyces cerevisae is very potential to be used as a regenerative therapy of Parkinson's disease. Beta glucan can increase the mobilization of hematopoietic stem cells (HSCs) from the bone marrow into the damaged tissues. Hematopoietic stem cells (HSCs) which have been mobilized can regenerate and differentiate into brain cells so that the symptoms of Parkinson would be reduced. This research aims to find out the effects of the addition of Saccharomyces cerevisae toward the number of brain cells in substantia nigra Parkinson’s rat model. Method. The research was experimental in vivo using the draft of randomized post test only controlled group design. There were five groups that become the sample in this research with 5 rats for each group, i.e. negative control group, positive control group, Treatment Group 1, 2 and 3 (Rotenone + Saccharomyces cerevisae 18 mg/kgBB, 36 mg/kgBB, 72 mg/kgBBfor 4 weeks. Variable measured in this study was the number of brain cells in substantia nigra. The results of this study showed that Treatment Group 3 (72 mg/kgBB) was a group with the largest number of brain cells than the other treatment groups. Statistical data obtained showed that the average number of brain cells in negative control group was 192.00 cells; positive control amounted to 116.80 cells; Treatment 1 amounted to 135.40 cells; Treatment 2 amounted to 140.80 cells; and Treatment 3 amounted to 161.80 cells. Result. The result of ANOVA test showed a significant difference between groups (p< 0.05), while the correlation test result indicated a strong correlation between the dose of Saccharomyces cerevisae and the number of substantia nigra of rat’s brain cells (r = 0,818). Conclusion. From this research, it can be concluded that the addition of Saccharomyces cerevisae with a dose of 18mg/kgBB, 36mg/kgBBdan 72 mg/kgBB is able to increase the number of brain cells in the substantia nigra of the brain of Parkinson’s Strain Wistar rat model significantly. The maximum increase in the number of brain cells is found after given the Saccharomyces cerevisae with the dose of 72mg/kgBB.

Purpose: Breast cancer is the most common female malignancy in the world. Beta glucan may improve quality of life in cancer patients receiving chemotherapy. The aim of this trial was to determine the effect of Beta glucan on quality of life in women with breast cancer undergoing chemotherapy. Methods: This study was conducted on 30 women with breast carcinoma. The eligible participants were randomly assigned to intervention (n=15) or placebo (n=15) groups using a block randomization procedure. Patients in the intervention group received two 10-mg capsules of soluble 1-3, 1-6, D-beta glucan daily and the placebo group received placebo for 21 days, in an interval between two courses of chemotherapy. Health - related quality of life (HRQL) was evaluated using the EORTC Quality of Life Questionnaire version.3.0 (EORTC QLQ-C30) at the beginning and end of the study. Results: At the end of the study, the Global health status /QoL score for the Beta glucan group was significantly increased (P=0.023), but the difference between the two groups was not significant. After intervention, the Functional scales score showed no significant change (P=0.099) between the two groups or within the groups. At the end of the study, the Symptom scales\items score was decreased significantly in Beta glucan group comparing the placebo group (P=0.048), as well as after adjusting for baseline score. The Symptom scales\items score’s change was significant (P=0.012) within the Beta glucan group, compared with the baseline score. Conclusion: The findings suggest that Beta glucan may be useful as a complementary or adjuvant therapy for improving quality of life in breast cancer patients in combination with cancer therapies.

We investigated the histopathological effects of methotrexate (MTX), a chemotherapeutic agent, and beta glucan (BG), an antioxidant, on rat testis. We used four groups of Sprague-Dawley male rats: MTX, MTX + BG, BG, and control. The MTX group was exposed to a single dose of MTX on the first day of experiment. The MTX + BG group was exposed to a single dose of MTX and BG on the first day of experiment followed by BG for 4 additional days. The BG group was exposed to BG for 5 days. The control group was given saline for 5 days. On day five, all animals were sacrificed and testicular tissue was evaluated for histopathology and the terminal deoxynucleotidyl transferase (TdT) deoxyuridine triphosphate nick-end labeling assay (TUNEL) was used to detect apoptosis. The apoptotic index (AI) and testicular damage increased in the MTX group compared to the other three groups. Histopathology was reduced in the MTX + BG group compared to the MTX group. Seminiferous tubule diameter was reduced in the MTX group compared to the BG group; we found no difference between control and BG groups. The thickness of th e germinal epithelium was reduced in the MTX group compared to the other groups. We found no difference in testicular weight among the groups. We compared body weight before and after the experiment; weights in the MTX and MTX + BG groups were significantly reduced compared to controls. In the control groups, we found a statistically significant increase in body weight, whereas there was no change in the BG group. We found that MTX causes deleterious effects on testicular tissue and that beta glucan may be protective. [ABSTRACT FROM AUTHOR]

β-(1,3)- d -glucan (BDG) is used to rule out invasive fungal disease (IFD) but its usefulness in cystic fibrosis (CF) has not been evaluated. We measured serum BDG in CF patients with no clinical suspicion of IFD. Samples from 46 adult CF patients during a stable period and during pulmonary exacerbation were tested. The association of BDG with clinical variables was analyzed. Three hundred and three non-CF patients with suspected IFD were used as comparators. Both samples were negative in 52% of CF patients, whereas 67% of comparators had only negative results ( P = 0.08). CF patients with pancreatic insufficiency and CF-related diabetes had fewer negative results ( P < 0.05 for both). Negative results were more common in older CF patients ( P < 0.05). Use of antibiotics, presence of fungi in sputum and CF liver disease did not impact BDG levels. In conclusion, patients with CF experience significant BDG antigenaemia in the absence of IFD.

The present study provides a more holistic view on consumers’ hedonic food experience compared to what is traditionally seen in sensory research, by integrating the hedonic sensory experience and post-ingestive sensations in one study to understand food satisfaction. The study was performed using apple-cherry fruit drinks with different levels of beta-glucans and different sweeteners, sucrose or Stevia rebaudiana . The aims were: 1) to study the hedonic sensory experience, 2) to study time and product effects on post-ingestive sensations and satisfaction, and 3) to study main drivers of satisfaction. A randomized cross-over consumer study was conducted using 66 subjects. Hedonic ratings of sensory perceptions were collected immediately after intake, and subjective ratings of post-ingestive sensations were collected pre intake and in 10 min intervals up to 40 min post intake. Significant hedonic differences of sensory properties were found between all fruit drinks, except between the fruit drinks varying in type of sweetener only. Differences in post-ingestive sensations were found immediately – and 10 min post intake between fruit drinks with and without added beta glucan. Satisfaction with sensory attributes was found to be the main driver of food satisfaction, while post-ingestive sensations drove satisfaction as well. While replacing sucrose with Stevia rebaudiana did not affect the hedonic and post-ingestive sensations, addition of beta glucan resulted in both positive and negative post-ingestive sensations. In general, adding beta glucan without compromising satisfaction is difficult. This study show that a detailed description of hedonic sensory – as well as post-ingestive sensations can bring important information about factors driving consumers’ satisfaction.

Introduction BTH1677, a 1,3-1,6 beta-glucan immunomodulator, stimulates a coordinated anti-cancer immune response in combination with anti-tumor antibody therapies. This phase II study explored the efficacy, pharmacokinetics (PK), and safety of BTH1677 combined with cetuximab/carboplatin/paclitaxel in untreated stage IIIB/IV non-small cell lung cancer (NSCLC) patients. Methods Patients were randomized 2:1 to the BTH1677 arm ( N=60; BTH1677, 4 mg/kg, weekly; cetuximab, initial dose 400 mg/m and subsequent doses 250 mg/m, weekly; carboplatin, 6 mg/mL/min AUC (area-under-the-curve) by Calvert formula, once each 3-week cycle [Q3W]); and paclitaxel, 200 mg/m, Q3W) or Control arm ( N=30; cetuximab/carboplatin/paclitaxel as above). Carboplatin/paclitaxel was discontinued after 4-6 cycles; patients who responded or remained stable received maintenance therapy with BTH1677/cetuximab (BTH1677 arm) or cetuximab (Control arm). Investigator and blinded central radiology reviews were conducted. Efficacy assessments included objective response rate (ORR; primary endpoint), disease control rate, duration of objective response, time-to-progression and overall survival (OS); safety was assessed by adverse events (AEs). Potential biomarker analysis for BTH1677 response was also conducted. Results Compared to control treatment, the addition of BTH1677 numerically increased ORR by both investigator (47.8% vs 23.1%; p=0.0468) and central (36.6% vs 23.1%; p=0.2895) reviews. No other endpoints differed between arms. PK was consistent with previous studies. BTH1677 was well tolerated, with AEs expected of the backbone therapy predominating. Biomarker-positive patients displayed better ORR and OS than negative patients. Conclusions BTH1677 combined with cetuximab/carboplatin/paclitaxel was well tolerated and improved ORR as first-line treatment in patients with advanced NSCLC. Future patient selection by biomarker status may further improve efficacy Identifier: NCT00874848 [ABSTRACT FROM AUTHOR]

Oat is an excellent source of high-quality proteins. The protein content in cultivated oat is about 12%–15%. Oats with even higher protein contents would have great potential as a vegetative protein source. From a mutagenized oat population, 230 lines with seed protein levels of 15% or higher were identified from green house grown plants. Fifteen lines with protein levels ranging between 17 and 24% were chosen for further studies. The high protein character was confirmed by two consecutive propagations in the field. Crossings showed that the trait was stable and segregated in a Mendelian fashion. SDS-PAGE analysis revealed that the major increase was in globulin like proteins. In addition, total dietary fibre, β-glucan and lipid levels were quantified. No correlation between any of these characters and the high protein trait could be found. Thousand Kernel Weight was also monitored and shown to be stable in the high protein lines. Thus, starting from the lines presented here a further development of commercial oat varieties with protein levels of 20% or higher is feasible. Such a high protein oat would be very important to meet the consumers need for high-quality high-protein oat for the food and feed industry. [ABSTRACT FROM AUTHOR]

Design: Functional foods may be useful for people with diabetes. The soluble fibers beta glucans can modify starch digestion and improve postprandial glucose response. We analyzed the metabolic effects of a specifically designed 'functional' bread, low in starch, rich in fibers (7 g/100 g), with a beta glucan/starch ratio of (7.6:100, g/g), in people with type 2 diabetes mellitus. Methods: Clinical and metabolic data from two groups of age-, sex- and glycated hemoglobin-matched diabetic subjects, taking either the functional bread or regular white bread, over a roughly six-month observation period, were retrieved. Results: Bread intake did not change during the trial. The functional bread reduced glycated hemoglobin by ~0.5% (absolute units) vs. pre-treatment values (p = 0.028), and by ~0.6% vs. the control group (p = 0.027). Post-prandial and mean plasma glucose was decreased in the treatment group too. Body weight, blood pressure and plasma lipids did not change. The acceptance of the functional bread was good in the majority of subjects, except for taste. Conclusions: A starch-restricted, fiber-rich functional bread, with an increased beta glucan/starch ratio, improved long term metabolic control, and may be indicated in the dietary treatment of type 2 diabetes.

ObjectivesThis experimental study investigated the possible protective effect of beta glucans on amikacin ototoxicity.MethodsThirty-eight rats with normal distortion product otoacoustic emissions (DPOAEs) were divided into four groups. Group K was the control group. Group A was injected intramuscularly (i.m.) with amikacin 600 mg/kg/day between days 1-15. Group AB was given beta glucan gavage 1 mg/kg/day on days 0-15 and given amikacin 600 mg/kg/day i.m. on days 1-15. Group B was administered only beta glucan gavage, 1 mg/kg/day, on days 0-15. The DPOAEs were elicited in different frequency regions between 2,003 and 9,515 Hz, as distortion product diagrams (DPgrams), before and after the medication was administered, in all groups, on days 1, 5, 10, and 15.ResultsNo significant changes in the DPgrams were observed in group K. In group A, significant deterioration was observed at the 8,003 and 9,515 Hz frequencies on day 10, and at the 3,991, 4,557, 5,660, 6,726, 8,003, and 9,515 Hz frequencies on day 15. For group AB, statistically significant deterioration was observed at the 2,824, 8,003, and 9,515 Hz frequencies on day 15. The results for group B showed a significant improvement of hearing at the 2,378, 2,824, 3,363, and 3,991 Hz frequencies on day 1, at the 3,363, 3,991, and 8,003 Hz frequencies on day 10, and at the 8,003 Hz frequency on day 15.ConclusionThis study suggests that amikacin-induced hearing loss in rats may be limited to some extent by concomitant use of beta glucan.

Functional diets are often given to fish during key stages to improve health through the interaction of the feed components with the host intestine. The additional factors added in these diets are known to modulate the immune response and as such may also offer protection against pathogenic challenges. The present study was undertaken to evaluate whether β-glucan supplementation for 6 weeks can alter the magnitude of immune response to immunological challenges and subsequently offer an improved innate immune response to bacterial challenge in rainbow trout. Two experimental diets were used to study these effects: a basic commercial diet supplemented with β-glucan and a commercially available functional diet (Protec™) that has β-glucan as a functional component in addition to other components were compared to a basic commercial control diet. No significant differences were observed in biometric data. Histological analysis revealed a significantly greater number of goblet cells in the fish fed Protec™ and β-glucan diets compared to those fed a control diet. Cell marker gene expression of distal intestine leucocytes indicated higher expression of T- and B-cells marker genes to both the β-glucan containing diets in comparison to control. The Protec™ diet demonstrated modulation of innate immune markers after 6 weeks of feeding with key antimicrobial genes (SAA, HAMP, IL-1β and TNFα) showing significant increases compared to the other diets. After stimulation with both PAMPs and an immune challenge with A. salmonicida fish fed the β-glucan diet and the Protec™ exhibited modulation of the innate immune response. An immune challenge with A. salmonicida was carried out to identify if dietary composition led to differences in the innate immune response of rainbow trout. Modulation of the magnitude of response in some immune genes (SAA, IL-1β and HAMP) was observed in both the distal intestine and head kidney in the Protec™ and β-glucan fed fish compared to those fed the control diet. • Dietary β-glucans improve innate immune function in fish intestine. • Dietary β-glucans improves gut health, with increased goblet cells in the distal intestine. • Higher levels of immune cell markers were observed in the fish fed the β-glucan diet. • Protec™ fed fish showed immunomodulation of proinflammatory genes in GALT cells. • Dietary β-glucans offer improved innate immune responses to Aeromonas salmonicida.
