this study was conducted to reveal the estrogenic effects of bisphenol a and o, p’-ddt on quailembryos. thirteen fertilized eggs were used as control (injected with 20 μl corn oil), 15 eggs were injectedwith estradiol 17β (0.04 mg dissolved in 20 μl corn oil), 20 eggs were injected with bpa (2 mg dissolved in20 μl corn oil) and 20 eggs were injected with o, p’-ddt (2 mg dissolved in 20 μl corn ...

Neonatal exposure of rats to bisphenol-A, an endocrine disruptor, has recently been proposed as a possible animal model of attention-deficit hyperactivity disorder, because such rats exhibit motor hyperactivity and impaired habituation to a novel environment 4-5 weeks after bisphenol-A pretreatment. To extend the original experiments, the present study additionally analyzed the effects of neona...

association with thyroid effects. But the safety of structurally similar bisphenol S (BPS), a widely used BPA replacement, has itself come under question, with one recent study indicating the compound disrupts cell signaling at extremely low doses. Although scientists are just beginning to analyze the safety of BPS, studies suggest this compound is already pervasive in the environment, in paper...

Various adverse effects of endocrine disruptors on the reproductive organs of male animals have been reported. We found that UDP-glucuronosyltransferase (UGT) activities towards bisphenol A, testosterone and oestradiol were significantly decreased in liver microsomes prepared from adult male Wistar rats administered with the endocrine disruptor bisphenol A (1 mg/2 days for 2 or 4 weeks). Howeve...

Bisphenol A is an industrial chemical widely used in plastic products with a consequent exposure to humans. To assess whether exposure to bisphenol A is associated with renal disease, we searched for low-grade albuminuria in 3055 Chinese adults in the Shanghai metropolitan area aged 40 years or older. Using a value for urinary albumin-to-creatinine ratios <30 mg/g, we examined its association w...

The purpose of our study was, to explore the possible ameliorating effects of black tea extract and quercetin, against bisphenol A-induced cytotoxicity. For this, human red blood corpuscles (RBC) were taken as the model. Blood samples collected in EDTA vials from healthy adults were used for preparation of RBC suspension. This suspension was treated with bisphenol A (0-150 microg/mL) with and w...
