Phencyclidine during pregnancy in the rat: effects on locomotor activity in the offspring.
Either 5 or 10 mg/kg of phencyclidine hydrochloride (PCP) was administered by gastric intubation to gravid rats during the last two weeks of gestation. Intubation controls received the vehicle and all offspring were fostered to untreated controls at birth. PCP produced a decrement in maternal weight gain and a small but nonsignificant reduction in birth weight that was no longer evident at weaning. There were no maternal deaths nor were resorptions or stillbirths increased by PCP exposure. Offspring were tested for differences in locomotor activity from birth to weaning at 30 days of age and during adulthood. No behavioral differences were found among the preweanling or adult offspring. Results are compared with other prenatal studies of PCP toxicity and teratogenicity.
