| Abstract: | The effect of intensive physical exercise (swimming for 3 hours with a load of 4% body weight) on the function of hepatic, pulmonary and peritoneal macrophages has been studied in rats and mice. NBT values in alveolar and peritoneal macrophages of the experimental animals proved to be 1.5 and 1.6 times higher than in the controls. The activity of cathepsin D in the liver, lung and Kupffer cells was greater than the control values. The data obtained indicate that intensive physical exercise caused depression in phagocytic activity of Kupffer cells, the major compartment of the reticuloendothelial system, whereas a similar function in lung macrophages was even greater than in the controls and in peritoneal macrophages changed but insignificantly. |
