[The ratio of various lymphocyte populations in bacillary dysentery and nonspecific ulcerative colitis]

The comparative study of the content of different lymphocyte populations of the peripheral blood in pathological states accompanied by lesions of the mucous membrane of the large intestine has been made. In shigellosis patients the accumulation of lymphocytes having the signs of young post-thymic forms (theophylline-dependent populations) and functionally active forms (Ea-rosette-forming cells) occurs in the circulating blood. In unspecific ulcerous colitis only an increase in the number of immature lymphocytes (theophylline-dependent lymphocytes and autorosette-forming cells) is observed. In both pathological states an increase in the number of O-lymphocytes with Fc gamma-receptors occurs in the circulation blood.
