Abstract | BACKGROUND/AIMS: METHODS: RESULTS: The numerical densities of the hepatocytes according to group were 0.000422, 0.00329, 0.000272, 0.00259, 0.00374 and 0.000346 μm3, respectively. Significant differences were found between values of all groups (p<0.01, Mann-Whitney U test). According to histopathological investigation, Group 3 and particularly Group 4 showed some microscopic abnormalities such as dilatation in sinusoids central veins and branches of portal vein, irregularities of the hepatocyte columns, significant mononuclear cell infiltrations, and unstained vacuoles in the cytoplasm of the hepatocytes. Histological structure was protected from the destructive effects of ovariectomy and hypertension in Groups 5 and 6. CONCLUSIONS: Our experimental results show that both hypertension and the postmenopausal period have negative effects on the number of hepatocytes and histological structure of the liver. Both amlodipine and lacidipine appear to ameliorate the hypertension and/or postmenopausal period-related decrease in hepatocyte number. We thus suggest that lacidipine and particularly amlodipine have important protective and recovering effects on the liver.
