Current view of zinc as a hepatoprotective agent in conditions of chlorpyrifos induced toxicity.

Human population bears the brunt of deadly hepatotoxic, neurodegenerative, behavioural and various other developmental disorders due to pesticide toxicity through environmental or occupational exposures. The application of pesticides to control pests in land and water has posed potential health hazards to live stock and wildlife including fishes, mammals, birds and humans. Therefore, various scientific approaches are being considered to tackle the problem of pesticide poisoning especially in developing economies. The role of essential trace elements as the promising and efficient preventive prophylactic agents without any toxicity and side effects in attenuating the adverse effects caused by pesticides, have been reported by various scientists, the world over. In this perspective, zinc, a key constituent of more than 300 mammalian enzymes and many transcription factors has proved its protective potential in various models of animal toxicity. The hepato-protective potential of zinc has been proved during various toxic states including pesticide toxicity. However, zinc warrants further examination with regard to documentation of specific molecular pathways to establish the exact mechanisms for zinc-mediated protection during pesticide toxicity.
