We examined how the experience of a threatening stimulus alters subsequent behavior in a situation where the immediate threat is absent. A small huddle of 12-day-old rats was exposed to a potentially infanticidal adult male rat for 5 min. During male exposure, pups were significantly more immobile than control pups. Thirty, 60, and 180 min after male exposure, the pups were isolated for 5 min f...

This study presents the effects of prenatal ethanol exposure on the morphology of the seminiferous tubules of the testes in the adult male rat. Timed-pregnant adult female Wistar rats (average weight 200 g) were given daily intragastric intubation of 5.8 g/kg ethanol between gestation days 9 and 12. Pair-fed and ad lib-fed animals served as controls. The pups were weighed at birth and weaned at...
