title: [Status of T-system immunity in patients with chronic diseases and cancer of the gastrointestinal tract].
abstract: The study was concerned with the immunity status of the cellular system in cancer patients and cases of chronic gastrointestinal diseases. The investigation used both standard procedure of spontaneous rosette formation and its modifications which provide indirect evidence on the status of separate subpopulations of immunocompetent cells. A reduced level of lymphocytes which form rosettes with ovine erythrocytes was found in cases of chronic diseases. Patients with gastrointestinal cancer revealed altered ratios of separate subpopulations of T-lymphocytes.
