Effect of a specific stress (aldrin) on rat progeny behavior

RESUMO

The effect of dam exposure to aldrin, an organochlorinated compound (1.0 mg/Kg, sc, daily), during pregnancy or lactation was studied in young tat pups (11, 15, 18 and 22 days of age) and in adult animals (90 days of age). Locomotor activity was significantly greater in both young and adult animals when compared to contols. Male rats that received aldrin during lactation also showed reduced plasma corticosterone levels. Maternal behavior was not affected bu treatment during either period. The results sugest that aldrin may act as a perinatal stress factpr
