Abstract:
Objective To explore the developmental toxicity of tributyltin chloride and the effects on sex hormone in female offspring rats through maternal gestation exposure. Methods Pregnant Wistar rats were randomly divided into four groups, 4 in each group. They were treated with TBTC by gavage at the dose of 0, 1, 2.5 and 5 mg/kg bw respectively from days 12-20 of gestation. 10 female offspring rats were randomly selected from each group and killed on postnatal day 70. The liver, kidney, uterus and ovary were weighed and the organ indexes were calculated. Pathological examination for liver, kidney, uterus and ovary were performed. Follicle stimulating hormone(FSH), luteotropic hormone(LH), testosterone(T) and estradiol(E2) in serum was determined by radioimmunity method. Results Increase of body weight in 2.5, 5 mg/kg bw groups significantly decreased(P
