Pharmacokinetics of gentamicin following single dose intravenous administration in normal and febrile goats.

A pharmacokinetic study of gentamicin (5 mg/kg intravenous (i.v.)) was conducted first in clinically healthy female goats and then in the same goats after induction of fever by Escherichia coli endotoxin (0.

Immunotoxic responses of cypermethrin, a synthetic pyrethroid insecticide in rats.

The study was undertaken to evaluate immunotoxic effects of cypermethrin administered orally (in ground nut oil) to male albino rats at dose levels (mg/kg) of 0 (control), 5, 10, 20 and 40 once daily for 90 days. Cypermethrin administration produced a significant leucopenia at 40 mg/kg on day 90. A dose dependent decrease (P greater than 0.

Effect of dietary malathion on hepatic microsomal drug-metabolizing systems of Gallus domesticus.

White leghorn cockerels were fed a diet containing 0, 400, 800 and 1600 ppm of malathion for 90 days. Malathion O,O-dimethyl S-(1,2-dicarbethoxy) ethyl phosphorodithioate) at 800 and 1600 ppm caused a significant decrease in body weights. There was a significant increase in liver/body weight ratio.
