he present work was designed to investigate the reproductive toxicity induced by oral administration of chlorpyrifos (CPF), cypermethrin (CYP) and their combination in adult male albino rats. Forty mature male albino rats were separated into four groups (10 each), the first group was used as control, while second, third and fourth groups received orally 1/20 LD50 of CPF (10 mg/kg b.wt), 1/20 LD50 of CYP (17.22 mg/kg b.wt) and 1/40 LD50 of CPF plus 1/40 LD50 of CYP (5 mg/kg b.wt CPF plus 8.61 mg/kg b.wt CYP) respectively for 26 days. The results revealed that exposure to CPF and/or CYP induced a significant decrease in the reproductive organs weight. Moreover, a significant decrease in spermatic picture (sperm cell concentration and viability) was observed with high percent of sperm abnormalities. Serum levels of testosterone and pituitary gonadotropins (FSH and LH) have been declined significantly in all treated groups. Significant elevations were observed in malondialdehyde and nitric oxide concentrations, while antioxidant enzymes superoxide dismutase and glutathione-S-transferase activities were decreased significantly as a result of induced oxidative stress. A significant drop in prostatic acid phosphatase activity was observed. Additionally, the results showed some histopathological alterations in the reproductive organs as well as neurological lesions in brain and pituitary glands. In conclusion, CPF and CYP induce deleterious effects on reproductive efficiency of male rats which reflect more obvious impacts when both combined

AbstractObjectivesThe main objective of the present study is to evaluate the mitigative effect of hydroalcoholic extract of Momordica cymbalaria fruits against sodium fluoride (NaF) induced hepatotoxicity.MethodsIn this study, Wistar male albino rats were randomly divided into five groups of six rats each. Group I and II served as normal and toxic controls. Group III as plant control received extract at a dose of 400 mg/kg b. wt, p.o and Groups IV and V as treatment groups received extract at a dose 200 and 400 mg/kg b. wt, p.o for 30 days. All groups except Groups I and III received 100 ppm of NaF through drinking water. After completion of the study, blood collected for the estimation of liver blood serum biomarkers such as aspartate aminotransferases (AST), alanine aminotransferases (ALT), alkaline Phosphatase (ALP), direct and total bilirubin, total protein and albumin. The liver tissue homogenate was for estimation of lipid peroxidation, catalase, and reduced glutathione levels.ResultsThe results showed that NaF intoxication caused elevation of liver blood serum levels and lipid peroxidation; decreased levels of serum total protein, albumin and liver reduced glutathione, and catalase observed. The treatment groups showed decreased elevated serum biomarkers (ALT, AST, and ALP), liver lipid peroxidation and increased serum total protein and albumin, liver reduced glutathione and catalase levels in a dose-dependent manner. Histopathological studies also further strongly supported for mitigative effects of the plant.ConclusionsIn conclusion, our findings of the study indicated that M. cymbalaria fruits were a potential drug candidate in the treatment of NaF induced hepatotoxicity.

Abstract Although abundant evidence exists that adverse events during pregnancy lead to chronic conditions, there is limited information on the impact of acute insults such as sepsis. This study tested the hypothesis that impaired fetal development leads to altered organ responses to a septic insult in both male and female adult offspring. Fetal growth restricted (FGR) rats were generated using a maternal protein-restricted diet. Male and female FGR and control diet rats were housed until 150–160 d of age when they were exposed either a saline (control) or a fecal slurry intraperitoneal (Sepsis) injection. After 6 h, livers and lungs were analyzed for inflammation and, additionally, the amounts and function of pulmonary surfactant were measured. The results showed increases in the steady-state mRNA levels of inflammatory cytokines in the liver in response to the septic insult in both males and females; these responses were not different between FGR and control diet groups. In the lungs, cytokines were not detectable in any of the experimental groups. A significant decrease in the relative amount of surfactant was observed in male FGR offspring, but this was not observed in control males or in female animals. Overall, it is concluded that FGR induced by maternal protein restriction does not impact liver and lung inflammatory response to sepsis in either male or female adult rats. An altered septic response in male FGR offspring with respect to surfactant may imply a contribution to lung dysfunction.
