Liver necrosis was produced in rats by administering 3 doses of a mixture of carbon tetrachloride + olive oil, 2 ml/kg, ip. The liver damage was evidenced by the elevated levels of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma glutamyl transpeptidase (gamma-GT) and by histopathological observations of liver sections. Aspartate and glutamate administration (100 mg/kg, ip) significantly reduced these elevated levels of AST, ALT, and gamma-GT. Carbon tetrachloride induced liver necrosis was also found to be significantly reduced in aspartate and glutamate pretreated animals as observed macroscopically and histologically.
