Effect of mancozeb on hepatic glutathione S-transferase in rat.
Oral administration of mancozeb (100 or 200 mg/kg body weight) for 7 consecutive days caused an increase in glutathione S-transferase (GST) activity in the liver of newborn, weanling and adult rats. This observed increase in GST activity was higher in weanling than in newborn and adult rats. Evaluation of acute effects at 4 and 20 h following oral administration of 200 mg mancozeb/kg showed a marginal increase in the levels of GST in adult rat liver. However, there was competitive inhibition of GST by the fungicide in vitro.
