Studies on the ameliorative effect of curcumin on carbofuran induced perturbations in the activity of lactate dehydrogenase in wistar rats

AbstractCarbofuran is known to inhibit neurotransmission system of insects. The present study was undertaken to evaluate the possible ameliorative effect of curcumin on carbofuran induced alterations in energy metabolism in brain and liver of rats. The results demonstrate that carbofuran caused a significant inhibition of lactate dehydrogenase (LDH) activity in rat liver but an increase in LDH activity in the brain. Increased LDH activity was also observed in the serum indicating organ damage in treated animals. Carbofuran caused an increase in level of pyruvic acid in rat liver but a decrease in the brain. A decrease in the level of soluble protein was also observed in the tissues studied. Pretreatment of animals with curcumin resulted in significant amelioration of the altered indices. These results indicate that carbofuran at sub lethal concentrations may adversely alter energy metabolism in brain and liver of non-target mammalian systems. Pretreatment of animals with curcumin may exhibit a potential to mitigate the carbofuran induced toxicity
