[Bile secreting function of the liver in birds of different ages with experimental atherosclerosis]

The bile-secretory function of normal liver and during the cholester-induced experimental atherosclerosis was studied in young (3-4-month-old) and adult (30-36-month-old) Russian white hens. In the course of natural ageing there was observed a decrease in the total and free serum cholesterol and in the bile-secretory function of the liver. Following the cholesterol administration these indices increased and the atherosclerotic injuries of the aorta developed. As compared with the young hens, the mentioned changes were more marked in adult experimental hens.
