ABSTRACT
Objective To explore the effects of passive smoking on pregnant rats and embryo development.Methods The pregnant Wistar rats were exposed to passive smoking4times per day,10min per time,continuously for20days,and the body weights were measured at the1st day,10th day and20th day.At the at20th day,the concentrations of NO in serum of pregnant rats were determined,simultansly the fetal death,embrgonic absorption were observed,the body weights,body length,tail length,brain weight and live weight of fetuses fetal growth retardation(IUGR)were observed.Results Significantly higher frequencies of fetal death,embryonic absorption,IUGR and significantly lower concentration s of NO in serum of pregnant rats were found in experiment group exposed to passive smoking.Significantly lower levels of body weight,body length,tail length,brain weight of fetuses were found in experiment group exposed to passive smoking compared with those of controls(P
