Abstract

The present study is aimed at investigating the potentials of low concentration administration of monosodium glutamate in inducing hepatotoxic effects in male albino rats. Thus, monosodium
glutamate at a dose of 5 mg/kg of body weight was administered to adult male albino rats by oral intubation. Treatment was daily for 28 days. The monosodium glutamate treatment significantly (p<0.05)
decreased the serum alkaline phosphatase activity by 71.97% but increased (p<0.05) the serum enzyme activities of aspartate aminotransferase by 66.86% and alanine aminotransferase by 9.15%. The treatment also increased (p<0.05) the serum malondialdehyde concentration by 287.15% and the serum aspartate aminotransferase-to-alanine aminotransferase ratio by 56.59%. Thus, treating rats with
monosodium glutamate at a low concentration (5 mg/kg of body weight) could be hepatotoxic without significant cholestasis or pathologies of the bone.
