Apilarnil is a bee product obtained after the collection of drone larvae aged 3-7 days. It contains water, proteins, carbohydrates, fatty acids, minerals, and is rich in essential amino acids, antioxidants, as well as reproductive hormones. It contributes to the maintenance of normal metabolism due to its amino acids, vitamins, minerals, glycerophosphate calcium and folic acid contents. This study was designed to investigate the effects of different levels of apilarnil supplementation to tris-egg yolk glycerol extender on post-thaw semen quality in 6 Akkaraman rams aged around 2 years. Semen was collected by artificial vagina and diluted at 37°C using five semen diluents with or without Apilarnil including 0% (Control), 0.5, 1.0, 1.5 and 2.0% apilarnil. Diluted semen was cooled to 5°C; after glycerolisation and equilibration, it was frozen in liquid nitrogen, stored at -196oC and evaluated for post-thaw sperm quality. According to our results, total sperm motility, progressive sperm motility and curvi-linear velocity (VCL) values were higher in 0.5, 1.0 and 1.5% apilarnil supplemented groups compared to the control group (P<0.05). Values for sperm acrosomal damage were decreased in all apilarnil-containing groups than in the control group (P<0.05). Plasma membrane integrity was higher in the 0.5, 1.0, and 1.5% apilarnil-containing groups than in the control group (P<0.05). Malondialdehyde levels were lower in all apilarnil-treated groups compared to the control group (P<0.05). In conclusion, supplementation of apilarnil at 0.5, 1.0 and 1.5% to tris-egg yolk glycerol diluent increased sperm motility and protected plasma membrane integrity and acrosomal membrane integrity of postthaw ram spermatozoa.

The basic mechanisms of ageing and longevity are not yet fully understood. More studies are needed to correlate this situation with functional foods and food supplements that have been used frequently recently. Bee products are in the first place in the use of natural products and food supplements. It has been reported that drone larvae (apilarnil) and queen bee larvae, which have become popular in recent years, support the protection of health due to their high nutritional value, but no studies have been conducted on their life-extending efficacy. For this purpose, the efficacy of these two bee products on life span and mortality was investigated in our study. Apilarnil and queen bee larvae lyophilisates added to Drosophila melanogaster medium at different concentrations (0.5; 1.0; 2.5 and 5.0 mg/ml medium) were studied separately in male and female populations for treatment and control groups. As a result, apilarnil at 5 mg/ml concentration showed the best effect in terms of larval mortality compared to the control group, while the most effective group in terms of mean life span was determined as queen bee larvae with 83.1±3.53 days. In general, both bee products increased the life span of flies in parallel with the increase in concentration in both female and male populations. These results were statistically significant at p<0.05 level compared to the control group. In our study, it was concluded that apilarnil and queen bee larvae lyophilisates can be used in terms of life-length increasing activity, but the underlying mechanisms should be elucidated by detailed studies.

Background: Bee therapy (Apitherapy, Api-treatment, Bee treatment) is a type of biotherapy that uses bees and their products as medicinal or preventative measures to control progression of diseases. In many countries today, apitherapy is a section of complementary and integrative medicine. The aim of this review is to explore the different bee products and their therapeutic potentials. Method: We searched the literature and then explored and evaluated evidence for bee products’ composition, therapeutic abilities and novel techniques used to enhance their effectiveness. Results: Data revealed that there are continuous advances in research and clinical trials of bee therapy. A better understanding of the composition of bee products generated great interest in their use for medical treatments. Bee products either collected or synthesized promote healing through reducing inflammation, enhancing circulation, and inducing a healthy immunological response, Furthermore, researchers have developed innovative approaches such as nanoparticles, scaffold, nanofibers, and others to increase the bioavailability of bee products and overcome problems with the traditional use of these products. Conclusion: Bee therapy is a simple, accessible, and easy-to-use pharmaceutical that is used in conventional medicine and has the potential to treat a variety of diseases. However, further studies are needed to prove its efficacy, and safety. Lack of practice regulations is still an issue.

For centuries, honey bee products such as honey, bee pollen, royal jelly, bee bread (Perga), and bee venom have been utilized in natural medicine due to their beneficial properties. A great deal of scientific research has been dedicated to exploring their physico-chemical properties and therapeutic effects. Despite this, drone larvae have not received as much attention from the scientific community. Within a honey bee colony, drones are responsible solely for fertilizing queen bee eggs and consuming food reserves collected by worker honey bees. As a result, beekeepers commonly remove excess drone brood from the hive, which is crucial for preventing and treating varroasis. Lyophilization is the most effective method for preserving drone larvae, and the physicochemical properties of fresh and lyophilized drone larvae were compared. The therapeutic effects of drone larvae, such as androgenic, hepatoprotective, immunostimulatory, and hypolipidemic effects in humans and experimental animals, were summarized. This study aims to summarize current scientific knowledge on drone larvae (apilarnil). The author utilized well-known publication databases like SCOPUS, Google Scholar, and Pub Med to gather research on drone larvae. Furthermore, this review collected information on the chemical composition preservation and bioactive action of drone larvae. Thanks to their high levels of amino acids, fatty acids, vitamins, minerals, and hormones, drone larvae can be considered a potential potency-raising agent.

Bee products have a millennia-old tradition in human apitherapy, thanks to their numerous curative properties. The aim of this study was to perform a physicochemical characterization, including the percentage of water content, dry matter, pH, acidity, impurity content, protein, ash, and macro and micro minerals, and to evaluate the antioxidant activity of apiculture products, including apilarnil, royal jelly, and propolis. Samples were collected from our apiary in the Banat region of Romania in 2022 as well as from the market. Apilarnil and royal jelly were analyzed in pure and freeze-dried form, and propolis in pure and tincture form. Our results show that there is a large variability in the chemical composition and antioxidant activity of the three bee products studied, depending on the form of presentation and source of origin. In the case of commercial bee products, the best results were obtained in terms of chemical composition, including the content of macro and micro nutrients. All the samples analyzed showed acidity, pH, and impurity content values within the limits allowed by the quality standards. Apilarnil from our own apiary recorded the highest values for antioxidant activity, followed by propolis tincture and fresh propolis from own apiary. [ABSTRACT FROM AUTHOR]

The main objective of this study is to examine the consumption preferences, trends, and purchasing behaviors of consumers residing in Izmir Province towards bee products before and after COVID-19. The main material of the study consists of online surveys conducted in March-April 2023 with consumers living in the seven districts of Izmir province with the highest population. The survey form comprises of three sections: consumption and purchasing behaviors of bee products, attitudes towards bee products, and questions on demographic characteristics of consumers. Since the first days when coronavirus cases began to emerge in our country, natural products that support the immune system such as bee products have been met with intense interest. The sustainability of bees and bee products in agriculture is always among the important issues. However, during the pandemic period, people's attention has been more focused on this issue. The value of honey and bee products, the miraculous food of nature, has been better understood, and this has been reflected in sales. If natural and economic conditions are favourable, this rise in the sector will continue. [ABSTRACT FROM AUTHOR]

Drone larvae (DL) has many biological activities thanks to the bioactive components it contains, but there are very few studies on its antimicrobial activity. The aim of this research was to determine the antifungal activity of DL (raw and lyophilised) water and ethanol extracts against fluconazole (FLU) sensitive and resistant yeast strains. The 87 fungal strains obtained from clinical samples were identified by phenotypic and molecular methods, and broth microdilution test was used for antifungal activity. All DL extracts had antifungal activity. The ethanolic extract of lyophilised DL showed higher antifungal activity. Total phenolic substance content and antioxidant activity of lyophilised DL ethanolic extract were found to be higher than other extracts. According to these results, the observed antifungal activity of DL extracts can be attributed not only to phenolic components, but also to synergistic effect of phenolic components with other bioactive components it contains.

Objective: Endotoxemia is a serious complication that is featured by hypotension, weak tissue perfusion and multiple organ failure that is among the top factors that lead to mortality in hospitalized patients. Apilarnil (drone bee brood) is a honeybee product that has biologically active characteristics. Apilarnil contains 25 - 35% dry matter, 9 - 12% protein, 6 - 10% carbohydrates, 5 - 8 lipids, 3% ash, and other unidentified substances. Additionally, its chemical composition includes vitamins (vitamin A, beta carotene, B1, B6, PP, and choline), minerals (calcium, phosphorus, sodium, zinc, manganese, iron, copper, and potassium), and essential amino acids that cannot be synthesized by humans or other animal organisms. Endotoxemia-induced cardiotoxicity is reported in the recent evidence. In this study, it was aimed to determine whether apilarnil, a bee product, has a protective effect on heart tissue in the case of endotoxic shock, which is one of the major causes of intensive care units, by histopathological and immunohistochemical evaluation of TNF-a and BNP in the heart tissue. Methods: 32 Sprague dawley male rats were randomly divided into four equal groups as control, apilarnil administered group (0.8 g/kg), lipopolysaccharide (LPS) group, and apilarnil together with LPS administered group. Immunohistochemical evaluation was performed to determine the differences in the expression of TNF-a and BNP in the heart tissue. Results: Edema, hemorrhage, and infiltration was observed in the LPS group compared to the control group and groups receiving apilarnil. It was observed that this damage decreased significantly in the group treated with LPS and apilarnil. Tumor necrosis factor-alpha (TNF-a) and brain natriuretic peptide (BNP) expressions were significantly increased in the LPS group, and coadministration of LPS and apilarnil suppressed these increased expression levels. Conclusion: Our data indicate that the protective effects of apilarnil may have a therapeutic effect on heart damage caused by LPS by the anti-inflammatory and antioxidant properties of the components found in apilarnil.

[Display omitted] • Microglia activation is involved in the neuropathology of Parkinson's disease (PD). • Apilarnil (API) is a bee product that is produced by lyophilizing drone larvae. • A dose–response study showed neuroprotective effects for API in a rat model of PD. • API high dose showed the best effects via rebalancing M1/M2 microglial activity. • API re-balanced M1 (iba-1/CD36/CXCL10) and M2 (CD206/Ym1/Fizz1/Arg-1) indices. Microglial activation contributes to the neuropathology of Parkinson's disease (PD). Inhibiting M1 while simultaneously boosting M2 microglia activation may therefore be a potential treatment for PD. Apilarnil (API) is a bee product produced from drone larvae. Recent research has demonstrated the protective effects of API on multiple body systems. Nevertheless, its impact on PD or the microglial M1/M2 pathway has not yet been investigated. Thus, we intended to evaluate the dose-dependent effects of API in rotenone (ROT)-induced PD rat model and explore the role of M1/M2 in mediating its effect. Seventy-two Wistar rats were equally grouped as; control, API, ROT, and groups in which API (200, 400, and 800 mg/kg, p.o.) was given simultaneously with ROT (2 mg/kg, s.c.) for 28 days. The high dose of API (800 mg/kg) showed enhanced motor function, higher expression of tyrosine hydroxylase and dopamine levels, less dopamine turnover and α-synuclein expression, and a better histopathological picture when compared to the ROT group and the lower two doses. API's high dose exerted its neuroprotective effects through abridging the M1 microglial activity, illustrated in the reduced expression of miR-155, Iba-1, CD36, CXCL10, and other pro-inflammatory markers' levels. Inversely, API high dose enhanced M2 microglial activity, witnessed in the elevated expression of miR-124, CD206, Ym1, Fizz1, arginase-1, and other anti-inflammatory indices, in comparison to the diseased group. To conclude, our study revealed a novel neuroprotective impact for API against experimentally induced PD, where the high dose showed the highest protection via rebalancing M1/M2 polarization.

Apilarnil, a bee-derived product originating from drone larvae, offers a range of advantageous properties for both humans and animals. It functions as an antioxidant, provides neuroprotection, boosts fertility, and has antiviral capabilities. Additionally, it is a provider of androgenic hormones. These beneficial functions are supported by its chemical composition, which comprises mineral salts, vitamins, carbs, lipids, hormones, and amino acids. The current study aimed to evaluate the ameliorative effect of apilarnil against Bisphenol A (BPA)-induced testicular toxicity in male adult rats. Forty-eight Wistar albino rats were randomly classified into six groups. The first, second, and third received olive oil, BPA at a dose of 50 mg/kg body weight (bwt), and apilarnil at a dose of 0.6 g/kg bwt, respectively. The fourth, fifth, and sixth groups received apilarnil with, before, or after BPA administration, respectively. Phytochemical analysis using included linear ion trap-ultra-performance liquid chromatography-tandem mass spectrometry (LTQ-UPLC-MS/MS) and global natural products social molecular networking (GNPS) revealed the presence of lysine, 10-hydroxy-(E)-2-dodecenoic acid, apigenin7-glucoside, testosterone, progesterone, and campesterol. BPA administration decreased serum level of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, glutathione (GSH) concentration, total sperm count, motility, and vitality. Additionally, BPA increased sperm abnormalities, malondialdehyde concentration (MDA), and decreased proliferating cell nuclear antigen (PCNA) expression. The treatment with apilarnil ameliorated BPA reproductive toxicity in rats which was indicated by increased serum testosterone levels, normalized serum levels of FSH and LH, and concentration of MDA and GSH activity. Moreover, apilarnil improved sperm count, motility, morphology, and PCNA expression. Apilarnil was found to enhance reproductive hormones, MDA levels, antioxidant activity, and PCNA expression [Display omitted] • Bisphenol A (BPA)-induced reproductive toxicity due to induction of oxidative stress. • Exposure to BPA decreased sperm quality and increased testicular abnormalities. • Apilarnil alleviated BPA-induced sexual toxicity via its antioxidant activity. • Apilarnil increased plasma testosterone levels that were reduced in BPA-treated groups. • Apilarnil-treated groups showed significant nuclear expression of PCNA antibodies.

The wound-healing capacity of ointments based on bee products was investigated in vivo on three experimental models of incision, excision and heat burn. For this purpose, four ointments were prepared with propolis, honey, apilarnil (drone brood homogenate) and a mixture of these three apitherapy products. The ointments were applied topically for 21 days. Clinical and macroscopic evaluation was performed throughout the experiment, with the recording of the re-epithelialization period and determination of the wound contraction rate on days 6 and 9. The histopathological examination was performed on days 1, 3, 12 and 21 of the treatment. The topical formulations were also characterized from a rheological point of view in order to verify their stability. HPLC analysis of propolis revealed the presence of phenolic compounds, particularly ferulic acid and p-coumaric which were found in high amounts. All ointments had beneficial effects on wound contraction and the re-epithelialization period, but the most significant result, both macroscopically and especially in terms of histological architecture, was presented by the ointment that contains all three apitherapy products, due to their synergistic effect.

A lesser-known bee product called drone brood homogenate (DBH, apilarnil) has recently attracted scientific interest for its chemical and biological properties. It contains pharmacologically active compounds that may have neuroprotective, antioxidant, fertility-enhancing, and antiviral effects. Unlike other bee products, the chemical composition of bee drone larva is poorly studied. This study analyzed the chemical compostion of apilarnil using several methods. These included liquid chromatography-mass spectrometry (LC-MS/MS) and a combination of gas chromatography/mass spectrometry with solid phase micro-extraction (SPME/GC-MS). Additionally, antioxidant activity of the apilarnil was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. A chemical assessment of apilarnil showed that it has 6.3±0.00, 74.67±0.10 %, 3.65±0.32 %, 8.80±1.01 %, 13.16±0.94 %, and 8.79±0.49 % of pH, moisture, total lipids, proteins, flavonoids, and carbohydrates, respectively. LC-MS/MS analysis and molecular networking (GNPS) of apilarnil exhibited 44 compounds, including fatty acids, flavonoids, glycerophospholipids, alcohols, sugars, amino acids, and steroids. GC-MS detected 30 volatile compounds in apilarnil, mainly esters (24 %), ketones (23.84 %), ethers (15.05 %), alcohols (11.41 %), fatty acids (10.06), aldehydes (6.73 %), amines (5.46), and alkene (5.53 %). The antioxidant activity of apilarnil was measured using DPPH with an IC 50 of 179.93±2.46 μg/ml., (© 2024 Wiley-VHCA AG, Zurich, Switzerland.)

Abstract Background and purpose: Apitherapists promote the medical use of products from the beehive (bee venom, propolis, pollen, honey, royal jelly, dead bees, apilarnil, wax, wax moths), the use of beehive air or therapeutic sleep on a beehive. However, little is known about how far such treatment options are perceived as acceptable by patients. Methods Patients visiting either a family doctor in Kehl or a gynecologist in Weilburg (both in Germany) were asked to rate their knowledge of apitherapy as well as their readiness to use apitherapeutic measures. Results Honey and propolis represent the best-known bee products whereas beehive air and apilarnil are greatly unknown to the patients. Only honey seems to be an acceptable treatment option whereas propolis, pollen and royal jelly seem to be less acceptable. Bee venom was not considered an interesting treatment possibility and, in particular, live bee stings were considered less desirable. This study found that gender and acquaintance with a beekeeper influenced the patients' ratings but age, education and current medical condition did not. Conclusion Live bee stings, apilarnil or the inhalation of beehive air are not appealing to the majority of patients. Before apitherapeutic methods are promoted, it seems to be important to know about patients' willingness to tolerate such treatments. Perhaps therapy modifications can be offered which seem more acceptable. Highlights • This study is one of the first which tries to identify the readiness of patients to accept the treatment with various bee products. • Only honey can to be considered as an acceptable treatment option but bee venom, in particular, live bee stings were rejected in most cases. • It is important to understand the patients' readiness to accept certain treatment options in order to tailor natural therapies to their needs.

Drone brood homogenate is a little-known bee product used in folk medicine to treat various health problems. It is a very nutritious milky substance with high content of nutrients: proteins, lipids, fatty acids, carbohydrates, vitamins (A, B, E and D), and minerals. Moreover, when collected on early stage of larvae development, it is, most of all, rich source of sex hormone (testosterone, progesterone and estradiol). Some beekeepers consider drone brood as a waste product, although in some countries they use it to fight Varroa. Meanwhile, in many scientific reports a curative effect of bee drone homogenate in treating urgent global health problems have been confirmed, including ovarian dysfunction in women and male infertility, thyroid and immunity disorders, as well as malnutrition in children. A few dietary supplements based on drone brood are available online. Many patents relating to drone brood-based dietary supplements have been filed in Russia, but their prevalence in EU countries is still limited. Further research is needed to fully recognize the pharmacological activity and increase the use of drone brood.

Apilarnil is 3-7 days old drone larvae. It is an organic bee product known to be rich in protein. In this study, the biological activities of Apilarnil were determined by its antioxidant and enzyme inhibition effects. Antioxidant activities were determined by Fe 3+ , Cu 2+ , Fe 3+ -TPTZ ((2,4,6-tris(2-pyridyl)-s-triazine), reducing ability and 1,1-diphenyl-2-picrylhydrazyl (DPPH⋅) scavenging assays. Also, its enzyme inhibition effects were tested against carbonic anhydrase I and II isoenzymes (hCA I, hCA II), acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Antioxidant activity of Apilarnil was generally lower than the standard molecules in the applied methods. In DPPH⋅ radical scavenging assay, Apilarnil exhibited higher radical scavenging than some standards. Enzyme inhibition results towards hCA I (IC 50 : 14.2 μg/mL), hCA II: (IC 50 : 11.5 μg/mL), AChE (IC 50 : 22.1 μg/mL), BChE (IC 50 : 16.1 μg/mL) were calculated. In addition, the quantity of 53 different phytochemical compounds of Apilarnil was determined by a validated method by LC/MS/MS. Compounds with the highest concentrations (mg analyte/g dry extract) were determined as quinic acid (1091.045), fumaric acid (48.714), aconitic acid (47.218), kaempferol (39.946), and quercetin (27.508). As a result, it was determined that Apilarnil had effective antioxidant profile when compared to standard antioxidants., (© 2023 Wiley-VHCA AG, Zurich, Switzerland.)

Given their beneficial effects in terms of health, the natural products, especially beehive products, have drawn the attention of consumers since long time ago. In order to guarantee the quality of these products on the market, their chemical composition needs to be analyzed. Thus, this current research had as objective the establishment of quality parameters for beehive brood food derived products: apilarnil and queen bee larvae triturate. These two products were compared with royal jelly which is the basis of brood food in the first 3 days of larval stage. The carbohydrates were determined by HPLC-IR and allowed the identification of seven carbohydrate compounds, predominantly glucose, fructose and sucrose. The lipid profile was analyzed by the Soxhlet method. The total protein content was determined by the Kjeldahl method. Free amino acids were analyzed by LC-MS. A total of 31 amino acids were identified of which nine are essential amino acids for humans. [ABSTRACT FROM AUTHOR]

This paper contains a summary about chemical composition of apilarnil (drone bee larvae), determining moisture, ash, free acidity, total protein and sugars content. Apilarnil is widely used in commercial medical products and cosmetics in many countries. The composition of apilarnil is quite complex and is not detailed in the literature. Seven samples of apilarnil were analyzed and compared with literature data regarding the physico-chemical parameters. This preliminary study presents a basic battery of tests for quality of apilarnil, which may be used as food supplement or in other domains. [ABSTRACT FROM AUTHOR]

In this study, we aimed to investigate the protective effect of apilarnil on kidney damage in the sepsis model induced by LPS. 64 Sprague Dawley adult male rats were randomly divided into eight groups; control group, groups in which 0.2, 0.4 and 0.8 g/kg/bw apilarnil (API) was applied by oral gavage method for 10 days, LPS group in which 30 mg/kg/bw lipopolysaccharide (LPS) administered as intraperitoneally, groups in which LPS + 0.2, LPS+ 0.4 and LPS +0,8 API was applied. Six hour after the last administration the rats were anesthetized for euthanasia and kidney tissues were removed for RT-PCR analysis, immunohistochemical analysis and histopathologic analysis. According to the results of RT-PCR expression levels of IL-6, IL-1β, NF-κB, TNF-α and TLR4 were significantly reduced in the LPS + 0,8 API group. Immunoreactivity of TLR4, pNF-κB and TNF-α levels in the LPS + 0.8 apilarnil group were significantly lower than in the LPS and LPS + 0.2 apilarnil groups. Histologically, compared to the LPS group the glomerular damage score tended to decrease in the LPS + 0,4 API and LPS+ 0,8 API groups, while the tubulointerstitial injury score decreased especially in the LPS + 0,8 API group. In the present study, 0,8 g/kg dose of apilarnil promoted potential renoprotective effects which were achieved, at least in part, by the modulation of important markers of the local immune response in the model of LPS-induced sepsis.

Drone brood homogenate is a little-known bee product used in folk medicine to treat various health problems. It is a very nutritious milky substance with high content of nutrients: proteins, lipids, fatty acids, carbohydrates, vitamins (A, B, E and D), and minerals. Moreover, when collected on early stage of larvae development, it is, most of all, rich source of sex hormone (testosterone, progesterone and estradiol). Some beekeepers consider drone brood as a waste product, although in some countries they use it to fight Varroa. Meanwhile, in many scientific reports a curative effect of bee drone homogenate in treating urgent global health problems have been confirmed, including ovarian dysfunction in women and male infertility, thyroid and immunity disorders, as well as malnutrition in children. A few dietary supplements based on drone brood are available online. Many patents relating to drone brood-based dietary supplements have been filed in Russia, but their prevalence in EU countries is still limited. Further research is needed to fully recognize the pharmacological activity and increase the use of drone brood. [ABSTRACT FROM AUTHOR]

• Apilarnil treatment reduced the histopathological changes caused by LPS. • Expressions of TLR4 signalling pathway increased by LPS administration were regulated by apilarnil treatment. • Apilarnil regulated increased apoptosis by LPS administration. • Apilarnil showed protective effect against DNA damage caused by LPS application. • Apilarnil showed protective effect against oxidative stress caused by LPS. Sepsis caused by infection is one of the most important problems of clinical medicine. This study aimed to determine the effect of Apilarnil (API), a bee product, on lipopolysaccharide (LPS) induced liver injury. In the study, 64 adult Sprague-Dawley rats were divided into eight groups; control, 0.2, 0.4 and 0.8 g / kg apilarnil (API) treated groups, LPS (30 mg / kg) group, LPS + 0.2, LPS + 0.4 and LPS + 0.8 g / kg API. At tissues obtained from rats, histopathological evaluation, biochemical analysis by ELISA (Catalase-CAT, malondialdehyde-MDA, superoxide dismutase-SOD, xanthine oxidase-XOD, and testican 1-TCN-1), immunohistochemical evaluation (Toll-like receptor 4 (TLR4), High Mobility Group Box Protein 1 (HMGB-1), nuclear factor kappa B (NF-κB), Tumor necrosis factor-alpha (TNF-α), Interleukin 1 beta (IL-1β), Interleukin 6 (IL-6) and Inducible nitric oxide (iNOS)), TUNEL analysis to determine the number of apoptotic cells and Comet test as an indicator of DNA damage were performed. Histopathological examination revealed dilated blood vessels, inflammatory cell infiltration, and pyknotic nuclei damaged hepatocytes in the liver tissues of the LPS group. It was found that tissue damage was decreased significantly in LPS + API treatment groups compared to the LPS group. The number of TUNEL positive cells observed in the LPS group in liver samples increased compared to control and API-treated groups only (p < 0.05). The number of TUNEL positive cells showed a statistically significant decrease compared to the LPS group in the groups treated with LPS + API. LPS treatment increased MDA, XOD, and TCN 1 levels and decreased SOD and CAT levels; this effect was reversed in the groups treated with LPS + API. In the LPS group, DNA damage was significantly increased when compared with the LPS + API. LPS treatment increased expression of TLR4, HMGB-1, NF-κB, iNOS, TNF-α, IL-1β, IL-6; in the groups treated with LPS + API reduced this increase. In conclusion, apilarnil administered in rats may be thought to prevent LPS-induced liver damage by inhibiting the TLR4 / HMGB-1 / NF-κB signaling pathway. [ABSTRACT FROM AUTHOR]
