Postnatal administration of allopregnanolone modifies glutamate release but not BDNF content in striatum samples of rats prenatally exposed to ethanol.

Ethanol consumption during pregnancy may induce profound changes in fetal CNS development. We postulate that some of the effects of ethanol on striatal glutamatergic transmission and neurotrophin expression could be modulated by allopregnanolone, a neurosteroid modulator of GABAA receptor activity. We describe the acute pharmacological effect of allopregnanolone (65 μg/kg, s.

Differential responses in central dopaminergic activity induced by apomorphine in IPL nude rat.

The IPL nude rat, derived by spontaneous mutation from the Sprague-Dawley strain, presents alterations in the prolactin synthesis and secretion due to an increased dopaminergic inhibition. However, there are no reports concerned to central dopamine activity. The corpus striatum is a brain area involved in the development of stereotyped behavior after the activation of mesolimbic and/or nigro-striatal dopamine pathways.
