Histopathological Changes on Liver Architecture Due to Toxic Effect of Chromium with Protective Role of Vitamin E on Albino Rats: A Prospective Study

Abstract

Abstract Introduction  This histopathological study was done with an aim to learn about the biohazardous effects of chromium toxicity with protective role of alpha-tocopherol on liver parenchyma of albino rat when fed orally. Materials and Methods  The study was conducted in the Department of Anatomy at Subharti Medical College, Meerut (Uttar Pradesh), India, in collaboration with Department of Pathology and Pharmacology. The experiment was conducted as per the guidelines of the Committee for Purpose of Control and Supervision of Experiments on Animals, with registration number 1204/PO/Re/S/2008/CPSEA, and with permission of the Animal Ethical Committee, on 36 adult male rats of ∼60 days of age; 140 ± 20 g of body weight was used; all the experimental animals were kept in polypropylene cage, and fed with pellet diet and water. Result  When exposed to chromium for long, it resulted in toxicity and damaged the cellular components during reduction process of chromium by releasing of free radicals, leading to deoxyribonucleic acid damage, but the chain-breaking antioxidant effects of alpha-tocopherol played an important role by reversing the damage caused by chromium toxicity, hence proved hepatoprotective. Conclusion  Vitamin E (alpha-tocopherol) is proved to be hepatoprotective against hepatotoxic effect of chromium metal.
