Effects of Hydrocortisone on Peritoneal Phagocytizing Cells in Rats under Conditions of [beta]-Adrenoceptors Blockade

Hydrocortisone decreased the count of peritoneal mononuclear phagocytes and mast cells and total phagocytic activity of peritoneal phagocytes in rats, but had no effect on the nitroblue tetrazolium test. beta-Adrenoceptor blockade abolished the suppressive effect of hydrocortisone on phagocytosis and prevented the decrease in the count of mast cells, but markedly reduced the number of neutrophils and parameters of stimulated nitroblue tetrazolium test.
