Rats offspring exposed to Ipomoea Carnea and handling during gestation: neurochemical evaluation

The present study evaluated the central monoamine levels of male and female adult rat offspring exposed orally by gavage to 0.0, 0.7, 3.0 and 15.0 mg/kg I. carnea aqueous extract daily, from gestation day (GD) 5 to GD 21. Several alterations in the monoamine activity systems were observed. However,...
