Effects of neonatal lead exposure on apomorphine-induced aggression and stereotypy in the rat. 1979

W G Drew, and J Kostas, and D J McFarland, and S E De Rossett

Rats were exposed to lead via the maternal milk. At 90 days of age, lead-exposed pairs and control pairs were tested for aggression induced by 5.0 mg/kg apomorphine. The large increase in aggression in response to apomorphine seen in controls was markedly attenuated in lead-treated subjects. In contrast, apomorphine-induced stereotypy was not affected. These results provide a further demonstration of persistent behavioral abnormalities resulting from early exposure to lead at levels which do not affect weight gain or mortality.

UI	MeSH Term	Description	Entries
D007774	Lactation	The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.
