Protective effect of curcumin during selenium induced toxicity on dehydrogenases in hepatic tissue.

Selenium administration resulted in a marked decrease in the activity levels of the liver succinate dehydrogenase, malate dehydrogenase, and lactate dehydrogenase while pyruvate dehydrogenase increased significantly (P<0.001) in the wistar rat. The degree of decrease of these enzymes was significantly less (P<0.001) when rats were treated with curcumin, a natural constituent Curcuma longa. Curcumin seems to prevent oxidative damage mediated through selenium and protect the dehydrogenases possibly through its anti-oxidative property.
