title: [Role of immunoregulatory cells and natural killers in the pathogenesis of multiple sclerosis].
abstract: Simultaneous investigations of the immunoregulatory cells and the natural killers were carried out in patients with different stages of multiple sclerosis in an attempt to determine a relationship between these organisms and the clinical stage of the disease. The quantities of E- and EAC-RFC in patients of all groups were within normal. The amount of T gamma-cells was decreased in the progressive phase of the disease and was significantly higher than normal during remission. The activity of the natural killers in the progressive phase of disease did not differ from control but was significantly depressed during remission with all effector/target ratios. The activity of the natural killers and the amount of T gamma-cells were found to be reversely correlated both in the progressive and remission phases of the disease. A quantitative reduction in the 0 population of lymphocytes was accompanied by a sharp suppression of natural killer activity.
