Abstract:
AIM To investigate the effects of in utero cocaine exposure on the fetal development, when fetuses were exposed to equal total dose but different dose and timing. METHODS Pregnant dams were randomly separated into three groups: SAL, COC20 and COC40. On E17, recorded body weight, brain weight and striatum weight of all groups, and examined the concentrations of DA and 5 HT in fetal striatum by HPLC. RESULTS Body weight of SAL, COC40, COC20 groups decreased progressively in turns. Brain weight of COC20 group and COC40 group was lower than that of SAL. Only the brain/body ratio of COC40 was decreased ( P
