[Plasmapheresis in the multomodality treatment of active respiratory sarcoidosis].

Eighty-four patients with different stages of respiratory sarcoidosis (RS) were examined. Plasmapheresis was performed during pathogenetic and symptomatic therapy. A comparative analysis was made in the patients from a control group who had no plasmapheresis sessions.

[Clinico-immunologic aspects of the differential diagnosis of disseminated processes in the lungs].

The results of examination of 224 patients with newly detected disseminated processes in the lungs who were admitted for differential diagnosis are presented. Immunologic studies which include determination of the natural killer activity, neutrophil phagocytosis, a total number of T- and B-lymphocytes and synthesis of antituberculosis antibodies in the indirect hemagglutination reaction with three basic M. tuberculosis antigens (phosphatide, polysaccharide and tuberculin) proved to be of high diagnostic value.

[Natural killers in the blood of patients with limited forms of pulmonary tuberculosis].

Activity of natural killer cells in blood of 47 new cases of limited tuberculosis of the lung was studied during their complex examination. There was a significant decrease in the activity of the natural killer cells in tuberculous patients which could be used as an additional criterion of the specific process activity.
