هدف: هدف از این مطالعه بررسی نقش بازدارندگی ویتامین e (ve) بر شاخص های اسپرماتوژنز رت ها به دنبال تیمار با bisphenol a بود. مواد و روش ها: رت های نر بالغ نژاد ویستار با میانگین وزنی10±231 گرم بهطور تصادفی به 4 گروه (6=n): کنترل، bpa (mg/kg/day250)، ve (mg/kg/day150) و bpa+ ve تقسیم شد. تیمار دهانی تا 56 روز و سه بار در هفته انجام گرفت. در پایان دوره تیمار، موش ها کشته شد و بیضه چپ آن ها توزی...
Background and purpose: Bisphenol A (BPA) is a toxic environmental pollutant that is released from different industries. The aim of this study was to investigate bisphenol A adsorption by activated carbon production from almond shell applying response surface methodology (RSM). Materials and methods: In this descriptive-analytic study, activated carbon production from almond shell was used as ...
Plasticizers with estrogenic activity, such as bisphenol A (BPA), have potential adverse health effects in humans. Due to mounting evidence of these health effects, BPA is being phased out and replaced by other bisphenol variants in "BPA-free" products. We have compared estrogenic activity of BPA with 6 bisphenol analogues [bisphenol S (BPS); bisphenol F (BPF); bisphenol AP (BPAP); bisphenol AF...
Background and purpose: Bisphenol A is a synthetic xenoestrogen that is used in large amount to produce polymers (polycarbonates, epoxy resins). It easily cross the blood-brain barrier and is reported to influence the central nervous system especially neurogenesis and synaptic transmission. In this research the effects of chronic administration of bisphenol A on spatial learning and memory in a...
P-136: The Protective Effect of Vitamin C on Adverse Effect of Bisphenol A on The Ovary in Adult Rat
Background: Bisphenol A (BPA), an estrogenic environmental contaminant is also known for oxidative stressinducing effect. The aim of this study was to investigate the effect of vitamin C as an antioxidant on the ovary tissue in adult rats treated with BPA. Materials and Methods: Adult female rats (200 ±20 g) were divided into 4 groups (n=6):control, bisphenol A (60μg/Kg/day) , vitamin C (150 mg...
Background: Bisphenol A (BPA) disturbs male reproductive system performance via the production of free radicals. Green tea extract (GTE) is known as a potent antioxidant. Objective: The aim of this study was to investigate the effect of co-treatment of BPA and GTE as an antioxidant on male reproductive system performance. Methods: Adult male rats were divided into 4 groups: control, Bisphenol A...
هدف: هدف از این مطالعه بررسی نقش بازدارندگی ویتامین E (VE) بر شاخص‌های اسپرماتوژنز رت‌ها به‌دنبال تیمار با Bisphenol A بود. مواد و روش‌ها: رت‌های نر بالغ نژاد ویستار با میانگین وزنی10±231 گرم بهطور تصادفی به 4 گروه (6=n): کنترل، BPA (mg/kg/day250)، VE (mg/kg/day150) و BPA+ VE تقسیم شد. تیمار دهانی تا 56 روز و سه بار در هفته انجام گرفت. در پایان دوره تیمار،...
Introdution: Bisphenol A (BPA) as an environmental pollutant has estrogenic effects and can induce oxidative stress in the testis tissue. The aim of the present study was to investigate the role of vitamin E (Vit E), as a strong antioxidant, on the adverse effect of BPA on adult rat testis tissue. Methods: Male rats (220±15g) were divided into 4 groups (n=6/each): control, Bisphenol A (...
