Hepatoprotective effect of carnosine on liver biochemical parameters in chronic ethanol intoxicated Rat

ABSTRACT

The aim of the present study is to investigate the effect of ethanol and the action of carnosine treatment on certain liver parameters, enzymes, total proteins and glycogen in rats. These enzymes including Krebs cycle enzyme succinate dehydrogenase [SDH]; glycolytic enzymes lactate dehydrogenase [LDH] d its isoenzymes; glycogenolytic metabolic machineries glycogen phosphorylase, G-6-Pase and glycoge" drolytic enzymes acid phosphatase [AP] and alkaline phosphatase [ALP]; amino acid metabolic enzymes aspartate aminotransferase [AST] and alanine aminotransferase [ALT] and nucleic acid catabolic enzyme 5-nucleotidase. The chronic ethanol-intoxicated rats showed a marked disturbance in all the parameters measured, indicating the toxic effect of ethanol by inducing oxidative stress on liver tissue. Administration of carnosine ameliorated the toxic effects of ethanol
