Abstract:
Objective To study the effects of perinatal exposure of diphenylchloroarsine chloride(DA)on the livability and reproductive function of F1 generation rats.Methods The pregnant rats were treated with DA by gavage at 0(solvent control),0.63(low dose),0.94(medium dose),1.89(high dose)mg/(kg?day)from day 6 of pregnancy to day 15 of lactation.The general condition,the change of body weight and abnormity of main organs of the F0 pregnant rats and F1 young rats were observed,and the livability and abnormity of reproductive function of F1 young rats were examined.Results The results indicated that compared with the negative control,the increasing amounts of the body weights of the F0 maternal rats and the livability of F1 young rats aged 4 day significantly decreased at 0.94 mg/kg and 1.89 mg/kg,the livability in lactation period obviously reduced at 1.89 mg/kg,and the rate of absorbed fetus in F1 pregnant rats increased at 1.89 and 0.94 mg/kg.Conclusion DA exposure may have an adverse effect on livability and reproductive function of the F1 offspring when the dosage is no fewer than 0.94 mg/kg.
