A number of pharmacological properties have been attributed to apigenin. In the present study the effect of apigenin was investigated with respect to hepatotoxicity induced by N-nitrosodiethylamine (NDEA), a compound that is present in many food stuffs and has been reported to be a hepatocarcinogen. Male rats were exposed to NDEA (0.1 mg/ml) dissolved in drinking-water separately, and with 10, 20, or 40 mg/ml of apigenin for 21 days. The activity of glutamic-oxaloacetic transaminase (SGOT), glutamic-pyruvic transaminase (SGPT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) was measured in blood serum. Lipid peroxidation, protein carbonyl content and micronucleus frequency were determined in hepatocytes. To assess the effect on DNA damage, the comet assay was performed on hepatocytes, blood lymphocytes and bone-marrow cells of the exposed rats. The results of the study reveal …
