Background: Lead (Pb) is classified as a major risk factor affecting the male reproductive system; however, itsprecise mechanisms of action are poorly understood and inconsistent. This work aimed to investigate effect ofPb toxicity on function.Methods: Accordingly, in this study, adult mice treated with acetate (PbAc) by gavage (200 mg/kg/day) for 28 days. We analyzed sperm count morphology, ox...

The Persian oak, Quercus brantii, trees in the Zagros region of Western Iran have been in decline since 2000. The decline is assumed to be highly connected with changes in meteorological parameters. Our objectives were to quantify the long-term trends in meteorological parameters and reference evapotranspiration (ET0) in the Zagros region and estimate ecohydrological parameters highly affected ...

To evaluate the effects of enterectomy on cellular and biochemical parameters of blood and peritoneal fluid, an experiment was conducted using 10 Iranian crossbred male goats. Ten milliliter of blood and 1-1.5ml of peritoneal fluid were sampled from all animals prior to operation for the estimation of control values. Enterectomy was performed under local anesthesia. Blood and peritoneal fluid s...

Hexavalent chromium as K2Cr2O7 (60mg/kgb.w) was administered intraperitoneally to male Sprague Dawley rats. In the thyroid gland, chromium concentration decreased significantly (P<0.01) as compared to the control tissue. Serum FT3 and FT4 levels decreased significantly (P<0.01 and P<0.001 respectively), while serum TSH concentration increased significantly (P< 0.01) than the control. Histologic...

the 60 apparently common carp, cyprinus carpio (mean weight 700g.) divided to two groups (1:control and 2: test) and transferred to 1000 liter indoor fiberglass tanks supplied with static well water, continuous aeration and defined water quality. test group was exposed to 30ppb (low concentration) cadmium as cdcl 2 (merck) control group was without cadmium addition . blood samples were caught r...

abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...
