摘要: Abstract Umbilical cord length has been considered a reliable indicator of fetal movement. In this study, the effect prenatal cocaine exposure on umbilical was examined in rats. Pregnant rats were intubated with either 0 or 60 mg/kg hydrochloride daily from gestation day (GD) 14–21. Fetuses removed via Caesarean section GD 21 and length, placental weight body measured. exposed to utero had significantly shorter cords than controls, although there no differences weights. These data suggest that suppresses movement, which could contribute some long-term effects observed cocaine-exposed offspring.
