PROTECTIVE EFFECT OF L-CARNITINE AND BAKER YEAST SACCHAROMYCES CEREVISIAE AGAINST HEPATIC TOXICITY INDUCED BY VALPROATE AS ANTIEPILEPTIC DRUG IN RATS
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 5
Abstract
Objective: The aim of this work was to investigate the protective role of L-carnitine and baker yeast (Saccharomyces cerevisiae) against the effect of sodium valproate (VPA) induced toxicity and oxidative stress in the liver.Methods: Chronic administration of sodium valproate was studied by oral administration of VPA for six months. The protective effect was conducted by an administration of L-carnitine or/and baker yeast for one month before chronic administration of VPA. Some biochemical parameters, lipid profile, oxidative stress and histopathological studies were analyzed.Results: Chronic administration of VPA for six months caused a significant increase in serum amino transferases (AST, ALT), alkaline phosphatase (ALP), bilirubin, total lipids, total cholesterol, low density lipoprotein (LDL) as well as oxidative stress; malodialdehyde (MDA) and nitric oxide. While decreased total protein, albumin, and globulin in addition to glutathione peroxidase and superoxide dismutase (SOD). The administration of L-carnitine and baker yeast cause significant decreases in the activities of AST, ALT, bilirubin, lipid peroxidation, LDL level and MDA levels and return the levels of total protein, albumin, globulin, glutathione peroxidase and SOD to the normal levels. Histopathological results revealed improvement of the liver structure.Conclusion: L-carnitine and baker yeast (Saccharomyces cerevisiae) offer protection to the liver by preserving the structural integrity of hepatocellular membrane against sodium valproate induced hepatotoxicity and oxidative stress.Â
