L-asparaginases convert L-asparagine into L-aspartate and ammonia. The L-asparaginase from Bacillus subtilis was cloned and expressed in the E. coli strain BL21(DE3)pLysS in the current study. Using glutathione sepharose 4B column chromatography, the L-asparaginase enzyme was uniformly purified 173.34 times, with a final specific activity of 1769.13 IU/mg protein and a yield of 56.14%. The isolated enzyme was identified as a 36 kDa polypeptide chain by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The immobilized enzyme was placed on top of the Ca alginate beads. The immobilized enzyme is quite stable and retains the majority of its activity at 4 °C (74 percent). The enzymatic and structural characteristics of free and immobilized recombinant L-asparaginase were studied. The activity of the free enzyme peaked after 30 min of incubation at pH 8.0 and 45 °C. After 30 minutes at 50 °C, the immobilized enzyme showed its peak activity at a pH of 8.5. The refined enzyme's amino acid makeup was identified. An enzyme that heals leukemia, Bacillus subtilis L-asparaginase, can be successfully mass-produced using this technique.

Urease is a metallo-protein in which two nickel (Ni) atoms are present at the active site. It is found in all the organisms such as, bacteria, fungi, plants, and in algae. Urease enzymes are also involved in catalyzing the hydrolysis of urea into CO2 and NH3. Urease is a virulence factor found in various pathogenic bacteria. It is essential in colonization of a host organism and in maintenance of bacterial cells in tissues. Due to its enzymatic activity, urease has a toxic effect on human cells. Current research work aimed to purify the three di-naphthodiospyrols namely; 5,4 -dihydroxy-1-methoxy-6,6 -dimethyl7,3-binaphthyl-1,4,5,8-tetraone (1), 5,8 -dihydroxy-5-methoxy-6,6-dimethyl-7,3-binaphthyl-1,4,1,4 -tetraone (2) and 8,5,8-trihydroxy-6,6-dimethyl-7,3-binaphthyl-1,4,1,4-tetraone (3) from the chloroform fraction of Diospyros lotus roots. The pure constituents (1-3) were evaluated for their urease inhibitory activity. Compounds (1-3) exhibited potent activity with IC50 value of 28.27 ± 1.68, 20.57 ± 2.00, 27.12 ± 2.45 µM respectively, when compared with standard thiourea (IC50 = 21.23 ± 0.12 µM). The pure isolated compounds (1-3) were also subjected to in silico studies to know their binding pattern with enzyme. The binding orientation and interactions with the important residues of urease enzyme revealed that the three compounds inactivate the enzyme activity by interacting with Ni bi-center as well as with the tailpiece residues.

Syzygium cumini L. (Jamun) is a Pakistani indigenous plant, which exhibits various diseases biological activities including antidiabetic, antiulcer, hepatoprotective, and even diuretic. The present work was carried out to provide a scientific justification to its use in folk medicine. In the current research work, the crude methanol extract and subsequent fractions of S. cumini fruits were subjected to phytochemical studies, along with urease, α-glucosidase, and phosphodiesterase inhibition profiling. Results showed that the plant is a rich source of various classes of compounds such as alkaloids, steroids, flavonoids, carbohydrates, phenols, glycosides, saponins, and tannins. In addition, results indicated that the crude extract and fractions significantly inhibit the aforementioned enzymes at tested concentrations. The observed urease inhibitory activity (IC50 values) of methanol, ethyl acetate, n-butanol, and chloroform were 10.17 ± 1.00, 7.09 ± 2.00, 8.32 ± 1.76, and 12.23 ± 1.09 µg, respectively.

Moreover, the inhibition of these enzymes provided a sound scientific backup to the mentioned folklores.

Diabetes is a chronic condition which is locally managed through the stem of Ficus foveolata. To find the exact chemical constituent responsible for this activity, a triterpene lactone (ficusonolide) isolated from F. foveolata was studied for antidiabetic potential through the in vitro antidiabetic paradigm employing L-6 cells and an in vivo antidiabetic assay against non-insulin-dependent rats. The results on glucose uptake in the L-6 cell line indicated that ficusonolide has enhanced the uptake of glucose by 53.27% over control at a dose of 100 μg/mL, while at doses of 50 and 25 μg/mL, the glucose uptake was enhanced by 22.42 and 14.34%, respectively. The extract of F. foveolata (100 mg/kg) and ficusonolide (50 mg/kg) demonstrated a significant (p < 0.001) decline in streptozotocin-induced hyperglycemia of diabetic rats. Ficusonolide displayed conspicuous inhibitory activity against the molecular docking studies with proteins such as dipeptidyl peptidase-IV (DPP-IV), protein tyrosine phosphatase 1B (PTP-1B), α-glucosidase, and α-amylase subjected to molecular targets. Detailed computational and structural insights affirmed promising interactions between target proteins and ficusonolide. In conclusion, the plant and its isolated compound have significant antidiabetic activity with a possible mechanism of interaction with DPP-IV, PTP-1B, α-glucosidase, and α-amylase.

Tobacco (Nicotiana tabacum) is an herbaceous plant originating from South America and processed into cigarettes for consumption. Polyphenols are considered vital components of tobacco in view of their contribution to antioxidant properties. This study aimed to determine the phenolic compounds in different tobacco varieties by applying cold extraction with methanol and distilled water. The extracts were screened for phenolic compound diversity and distribution as well as their antioxidant potential in different tobacco varieties. The results showed that the methanolic extract of tobacco SP-28 exhibited the highest value in the total phenolic content (24.82 ± 0.07 mg GAE/gd.w.) and total flavonoid content (4.42 ± 0.01 mg QE/gd.w.), while the water extract of tobacco SN-2 exhibited the highest value in the total condensed tannin (1.12 ± 0.03 mg CE/gd.w.). The radical scavenging capacities of tobacco SP-28 were relatively high in DPPH (18.20 ± 0.01 mg AAE/gd.w.) and FRAP (3.02 ± 0.10 mg AAE/gd.w.), whereas the ABTS value was the highest in tobacco SN-2 (37.25 ± 0.03 mg AAE/gd.w.), and the total antioxidant capacity was the highest in tobacco SN-1 (7.43 ± 0.18 mg AAE/gd.w.). LC-ESI-QTOF-MS/MS identified a total of 49 phenolic compounds, including phenolic acids (14), flavonoids (30), and other polyphenols (5) in four different tobacco varieties. Tobacco SP-28 showed the highest number of phenolic compounds, especially enriched in flavones. Our study highlights the antioxidant potential of tobacco extracts and reveals the phenolic distribution among different tobacco varieties that could support tobacco utilization in different pharmaceutical industries.

The Sophora mollis is one of the best anti-inflammatory, antioxidant, and anticancerous plant; therefore, the isolated chemical constituents, that is, scopoletin (1), pinitol (2), 2-propenoic acid, 3-(3,4-dihydroxyphenyl)-octacosyl ester (3), betulin (4), and β-sitosterol glucoside (5) were tested for these folklores. The structures of the isolated compounds were confirmed by 1H NMR, 13C NMR, 2D-NMR, and mass spectral data. The anti-inflammatory, anticancer, antiglycation, and antioxidant activities of compounds 1-5 were evaluated using different assays. Compound 1 exhibited significant anti-inflammatory effect as it reduced edema of the paw (83.98%), which is more potent than the standard drug (ibuprofen) (which showed an inhibition percentage of 73.22% a), followed by compound 3. Furthermore, compound 3 showed significant free-radical scavenging activity using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free-radical assay.

Evaluation of anticancer activity of isolated compounds reveals weak effect against HeLa and 3T3 cell lines. Docking studies of the most active compound into the binding sites of cyclooxygenase isoforms showed a better antagonistic potential against COX-1 than the COX-2 isoform.

The inadequate role of silver nanoparticles is evident from their underutilization in myriad applications in the modern era. Herein we report the environment-friendly, facile, and robust synthesis of silver nanoparticles (Ag-NPs) from alcoholic extracts of black cumin (Bunium persicum) seeds to reduce and stabilise agents. The extract principally consists of nigellon, terpenoid, thymoquinone, polyene, phenylpropanoids, and phototoxic furanocoumarins. The effect of pH revealed that the BCS@Ag-NPs were more stable at neutral pH than acidic and basic. A change in the size and number of BCS@Ag-NPs was observed at high sodium chloride solution concentrations showing their instability in a concentrated salt solution. The synthesized BCS@Ag-NPs were considered significant catalysts showed by approximate 99% conversion of the 4-nitrophenolate anion into 4-aminophenol in 24 min. The surface plasmon resonance of BCS@Ag-NPs at 430 nm was recorded on UV–Vis spectrometer, and particle size ranging from 35 to 77 nm was measured through scanning electron microscopic (SEM) analysis. FTIR spectra confirmed the presence of amines, alcohols and amide functional groups at 3365 cm−1, 1646 cm−1 and 1026 cm−1 capped along with the reduction of BCS@Ag-NPs. The firm peaks for Ag atoms in BCS@Ag-NPs at almost 0.4, 3.1 and 3.2 keV in EDX analysis showed the presence of elemental silver. Nevertheless, the alcoholic seed extract and synthesized BCS@Ag-NPs exhibited excellent various pharmacological activities. Both the tested samples significantly inhibited Urease, CA-II, PDE-I. The inhibitory potential against tyrosinase was appreciated against extract as compared to BCS@Ag-NPs. The alcoholic extract was effective in the inhibition of E. coli. Both of the tested samples proved significant analgesia in the acetic acid-induced writhing model. A noticeable sedative response was observed as a compared extract. No mortality was detected in acute toxicity. In conclusion, these results provide the scientific rationale to the folklore of black cumin for GIT problems, hypertension, bronchodilation and analgesic.

Fast, simple, and environmentally friendly gold nanoparticles (Au-NPs) capped and stabilized with black cumin (Bunium persicum) seed alcohol extract are reported. The aqueous gold ions (Au3+) were treated with B. persicum (BP) seed extract, which resulted in a rapid color change to red, indicating the synthesis of Au-NPs. UV-Vis spectroscopy, FTIR, SEM, energy dispersive X-ray (EDX), and X-ray diffraction (XRD) techniques were used to further characterize the Au-NPs. Its stability was assessed against various pH levels and sodium chloride levels (NaCl), different salts of same concentration as well as at a range of temperature (30–100°C). The UV-Vis spectrum in the Au-NPs produced a 540 nm plasmon surface resonance, and a 25–50 nm range of particulates was shown in the SEM analysis. In addition, the FTIR spectra confirmed the inclusion in the capping and decrease of Au-NPs of amines, amide groups, and alcohols. The EDX analysis confirmed the presence of element Au. Furthermore, Au-NPs were tested for enzyme inhibition and antibacterial and antifungal activities and showed remarkable response. These findings have concluded that BP seed extract is an effective bio-reductant of gold nanoparticle synthesis, which can be further applied in different biomedical and pharmaceutical industries.

Fernandoa adenophylla (Wall. ex G. Don) Steenis is traditionally used to cure various diseases and can be included as an ingredient in massage oils, which are supposed to comfort muscular tension and pain. This study was designed to assess the antinociceptive, muscle relaxant, and molecular docking properties of a novel compound, namely, (5aR,5a1R,6R,7aS,14bR,15R)15-hydroxy-7a-methyl-6-(2-methylprop-1-en-1-yl)-7,7a,14b,15-tetrahydro-5H-t-5a,15methanobenzo[g]benzo[5,6]azuleno[1,8-bc]chromene-5,9,14,16(5a1H,6H)- tetraone (peshawaraquinone), isolated from the methanolic extract of F. adenophylla in an animal model. The chemical structure of the isolated compound was elucidated using advanced spectroscopic techniques and further confirmed by XRD analysis. Compound 1 was tested against hot plate-induced noxious stimuli at various doses (2.5, 5, 10, and 15 mg/kg i.p.). The muscle relaxation potency of compound 1 was evaluated in the inclined and traction test, while the open-field test was used for the determination of sedative potential. The isolated compound was also subjected to acute toxicity analysis. The compound was then subjected to molecular docking analysis to determine the exact mechanism of action. Compound 1 demonstrated significant (p < 0.05) analgesic effect in a dose-dependent manner. A noticeable muscle relaxant effect was observed with the passage of time in both experimental models. The compound 1 showed a significant (p < 0.05) sedative effect, and in an acute toxicity study, the compound 1 was devoid of any noxious effects. The docking studies showed preferential affinity for μ-opioid and GABAA receptors. Hence, the prospective antinociceptive and muscle relaxant and sedative properties are probably mediated through these two target interactions.

Studies of the ethyl acetate extract bark extract of Olea ferruginea led to the isolation of one new compound Ferruginan A (1) in addition to two known compounds, Ferruginan (2) and cycloolivil (3). Structures of the isolated compounds were confirmed by mass spectrometry (MS) and NMR spectral data. The ethyl acetate fraction and compounds (1–3) were evaluated against breast cancer cell line (MCF-7) and as antioxidants using the free radical scavenging assay. Results revealed that compound 2 exhibits significant antioxidant activity with an I C 50 value of 21.74 μg/mL. In addition, the ethyl acetate fraction showed good cytotoxic activity (79.31% inhibition at 250 μg/mL), whereas compounds 1–3 exerted mild cytotoxic activity ( I C 50 = 8.03 – 12.01 μ g / mL ) as compared to the standard ( I C 50 = 4.41 μ g / mL ) against MCF-7. Docking studies suggested that antioxidant activity is due to the chelation of compounds with copper present in the active site of tyrosinase. These results suggest that the extract exhibits considerable antioxidant activity, and the isolated compounds exert moderate anticancer activity.

Diseases emerging from oxidative stress and inflammatory imbalance are deeply threatening the modern world. Fisheries by-products are rich in bioactive metabolites. However, they are usually discarded, posing a real environmental burden. Herein we aimed to explore the bioactive compounds, anti-oxidant, and anti-inflammatory capabilities of the shell of the freshwater Nile crab Potamonautes niloticus. Methanolic extract of crab shell was subjected to GC/MS and HPLC analyses of total lipids, flavonoids, and phenolic acids. Also, zebrafish Danio rerio was subjected to inflammatory status using CuSO

Investigation on medicinal plants' therapeutic potential has gained substantial importance in the discovery of novel effective and safe therapeutic agents. The present study is aimed at investigating the hepatoprotective potential of Seriphidium kurramense methanolic extract (SKM) against carbon tetrachloride- (CCl4-) induced hepatotoxicity in rats. S. kurramense is one of the most imperative plants for its various pharmacological activities. Therefore, this study was aimed at evaluating the hepatoprotective potential against CCl4-induced liver toxicity. The serum samples were analyzed for alanine aminotransferase (ALT) and aspartate aminotransferase (AST) together with the oxidative stress mediator levels as nitric oxide (NO), malondialdehyde (MDA), glutathione (GSH), reduced glutathione (GSH), and superoxide dismutase (SOD) as well as peroxidation and H2O2 activity. CCl4 administration resulted in an elevated free radical generation, altered liver marker (AST and ALT) enzymes, reduced antioxidant enzyme, and increased DNA damage. Methanolic extract of S. kurramense decreased CCl4-induced hepatotoxicity by increasing the antioxidant status and reducing H2O2 and nitrate content generation as well as reducing DNA damage. Additionally, SKM reversed the morphological alterations induced by CCl4 in the SKM-treated groups. These results demonstrated that SKM displayed hepatoprotective activity against CCl4-induced hepatic damage in experimental rats.

BACKGROUND AND OBJECTIVE Carissa edulis (CE) (Apocynaceae) is distributed in tropical Africa and Asia and commonly used in folk medicine to treat many diseases such as headache, cough, rheumatism and fever. The purpose of this study was to evaluate the protective role of ethanolic extract of CE, a medicinal plant locally called "Al-Arm" in Yemen, against liver injury induced by dimethoate (DM) intoxication in male guinea pigs. MATERIALS AND METHODS Animals were divided randomly into 5 groups and kept at 5 animals per group. The first group was served as a control group and administered with vehicle orally; the group II administered with DM (14 mg kg-1; 1/25 LD50) orally. Animals of group III, IV and V were administered with 100 mg kg-1 of CE extract, 200 mg kg-1 of CE extract and 100 mg kg-1 Liv-52 orally half hour before DM administration, respectively. All the previous administrations were repeated daily for 21 days. Data were analyzed by one-way ANOVA using SPSS. RESULTS The DM caused a statistically significant increase in the serum level of liver enzymes (AST, ALT, ALP) when compared to control animals, whereas CE and Liv-52 pre-treatment to the DM-intoxicated animals resulted in a significant normalization of the activities of enzymes. Similarly, a significant increase in lipid peroxidation (LPO) level, while induced significant decreases in the activities of liver catalase (CAT) and glutathione-S-transferase (GST). In contrast, co-administration of CE and Liv-52 to DM-treated animals restored most of these biochemical parameters to nearly normal levels. Histopathological examination of intoxicated animals showed many tissues alterations such as; vasodilation, hemorrhage, cytoplasmic vacuolization, inflammation and nuclear pyknosis indicating liver damage, while the animals received CE or Liv-52 showed less pathological effects when compared to animals treated with DM alone. CONCLUSION The biochemical and histological results confirmed the hepatoprotective effect of ethanolic extract of CE against DM-induced hepatotoxicity in male guinea pigs.

Traditionally, Diospyros lotus Linn is used for insomnia and other associated disorders. Insomnia is a worldwide disorder with different etiology which is treated with different synthetic medicine associated with addiction. Natural products are generally devoid of such addition with good efficacy. Current research was conducted to evaluate the sedative and hypnotic effects of dimeric naphthoquinones such as dinaphthodiospyrol A (1), dinaphthodiospyrol B (2), dinaphthodiospyrol C (3), dinaphthodiospyrol D (4), dinaphthodiospyrol E (5) and dinaphthodiospyrol F (6) isolated from the chloroform fractions of D. lotus. The sedative and hypnotic effects at the dose of 5 and 10 mg/kg (each compound) were assessed through open field and phenobarbital induced sleep test, respectively. In the case of open field test the administration of tested compounds significantly hindered the movement of animals, while in case of hypnotic effect the tested samples significantly improved the onset and duration of sleep as compared to control. The overall effects were in a dose dependent manner. The compounds were also assessed for acute toxicity, but no toxicity was observed. In this regard, our research triumphantly announced the strong chemical base for the folkloric values of the plant with their fringe benefits and implemented a platform for further aspects of mechanistic and clinical studies. A possible mechanism of in vivo inhibition was studied by using docking simulations on GABA receptors. Binding orientations and types of interactions revealed that a possible mechanism behind these pharmacological actions might be interaction with GABA receptors.

This study was aimed to evaluate the efficiency of Sargassumpolycystum and nucleotides- supplemented diets to improve immune response and cold-tolerance of juvenile Litopenaeus vannamei. Four treatments were evaluated: T1, the control, shrimp received only a basal diet, T2, a basal diet with 500 ppm nucleotides, T3, a basal diet with 500 ppm S.polycystum powdered, T4, a basal diet with 500 ppm nucleotides and 500 ppm S.polycystum powdered. Shrimp were fed experimental diets for 56 days. Results revealed shrimp fed T4 diet exhibited the best significant improvement in water quality, survival, growth, and feed utilization indices followed by T2, and T3, while T1 showed the worst values. Additionally, nonspecific immune responses (phagocytosis (%), lysozyme, phenoloxidase, super oxide dismutase (SOD) activity, total nitric oxide) were improved with 1.7–3.2-fold in T4 higher than T1. Histomorphology of hepatopancreas in T4 showed the most increased activation of the hepatic glandular duct system compared with the other treatments. Moreover, nucleotides/seaweed-supplemented diets upregulated relative expression of cMnSOD, Penaeidin4, and heat shock protein70 (HSP70) genes, while translationally controlled tumor protein (TCTP) was downregulated. In conclusion, the synergistic effects of both S. polycystum and nucleotides have many advantages as a growth promoter, immunostimulant, antimicrobial, and cold-tolerant stimulant to L. vannamei.

Fasting blood specimens were collected from all students for measurement of serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). The criteria of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) were used. Results: The mean age of the studied cohort was 19.8 ± 1.8 years; 48.3% were men and 51.7% were women. About 56.7% of the participants were from rural areas. Qat chewers and cigarette smokers comprised 63.3% and 6.7% of the cohort, respectively. No obese students were found in this study; however, 11.7% were overweight. The overall prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia, high LDL-C, and low HDL-C among the participating students were 86.7%, 21.7%, 23.8%, 31.7%, and 81.7%, respectively. Mixed hyperlipidemia was present in 8.8% of the students. The prevalence of isolated hypercholesterolemia, hypertriglyceridemia, and low HDL-C was 12.9%, 15%, and 70%, respectively. Dyslipidemia was significantly associated with male sex, increasing age, urban residence, and medical and natural science faculties. In contrast, smoking, qat chewing, physical activity, and the consumption of fast food, fruits and vegetables, and fish were not significantly associated with dyslipidemia. Conclusion: To our knowledge, this is the first human study conducted at Ibb University during wartime in Yemen. Dyslipidemia was highly prevalent among healthy Yemeni university students in Ibb city. Low HDL-C was the most prevalent type of dyslipidemia, followed by increased levels of LDL-C. Gender, age, residence, and type of faculty were also closely related to dyslipidemia. These results indicate the need for specialized programs to determine blood lipid levels and initiate intervention programs to reduce the prevalence and prevent the complications of dyslipidemia among Yemeni university students. الكلمات المفتاحية: اختلال الدهون في الدم, إب, الطلاب, ارتفاع الكوليسترول, زيادة الدهون الثلاثية في الدم, Keywords: Dyslipidemia, Hypercholesterolemia, Hypertriglyceridemia, Ibb, Students

Aims: To examine the effects of the administration of CD on lipid metabolism and liver enzymes in hyperlipidemic subjects. Study design: 20 subjects were divided into two groups, each containing ten subjects. Each subject in the 1st group ingested 1g, while the subject in the 2nd group ingested 2g of CD powder as a broth suspension in a single daily dose before lunch during the follow up period of one month. Patients kept their individual diet relatively constant. Methodology: We included 20 hyperlipidemic volunteers (men; age range 20-50 years) of a total of 80 subjects. Blood samples were taken and analyzed for total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), Low density lipoprotein cholesterol (LDL-C), atherogenic index (AI), serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). Results: The results of the present study show a significant decrease in the levels of TC, LDL-C and TG in 1g and 2g of CD administration groups by 12.6, 24.1, 17.1% and 19.9, 25.5 23.4% respectively while the level of HDL-C was significantly increased by 45.6 and 32.5% in 1g and 2g respectively. The atherogenic index (AI) was significantly decreased in 1g and 2g groups by and 47.4% and 45.5% respectively. Our results also show that, CD administration in 1g and 2g subjects causes a significant decrease in ALT and AST by 39.2, 32% and 48.5, 33.3% respectively while the level of ALP was non-significantly decreased. Conclusion: dietary supplementation with CD administration decreased serum lipid profile and liver enzymes in hyperlipidemic subjects. Therefore, it may be regarded as a useful therapy for hyperlipidemia and liver disease. However, further studies are required to compare it with other medicinal plants and with lipid lowering drugs.

Aims: To examine the protective properties of vitamin C (vitC) and E (vitE) on DM induced nephrotoxicity in male guinea pigs. Study Design:Twenty male rats were randomly grouped into four. �1 � = Control, �2 � = Vitamins (C & E) treated, �3 � = Dimethoate (DM) treated and �4 � = Vitamins treated plus DM treated.

Chlorpyrifos (CPF) is a widely used organophosphorus insecticide throughout the world inagriculture and anti-termites around homes. Silymarin is a naturally occurring substance and hasantioxidant effects. For decades, it has been used clinically in Europe for the treatment ofalcoholic liver disease and as anti-hepatotoxic agent. Therefore, the present study aimed toassess the protective and curative effect of silymarin in attenuating the CPF-inducedimmunotoxicity in rats, by measuring the level of immunoglobulin G (IgG), lymphocyteviability, neutrophil phagocytic function assay, total white blood cells count (WBC) and relativedifferential white blood cells count, as well as nitric oxide (NO) level and catalase activity. Thetreatment with CPF decreased lymphocyte viability, neutrophil phagocytic index, total whiteblood cells count, relative lymphocyte count, IgG concentration and catalase activity. On theother hand, a high level of NO was detected upon animal treatment with CPF. Interestingly,pre- and post-treatment with silymarin to CPF-treated group improved the lymphocyte viability,total white blood cells count, relative lymphocyte count, catalase activity and the NO level. Preandpost-treatment with silymarin recovered phagocytic activity of neutrophils and restored IgGlevel. In conclusion, silymarin has both protective and curative effects against CPF-inducedimmunotoxicity may be through its anti-oxidant effects.
