[Diagnosis of silicotuberculosis activity].

Possible determination of silicotuberculosis activity with various clinico-laboratory, roentgenological, biochemical and immunological procedures was analyzed by the materials on observation of patients with silicotuberculosis. The authors considered 117 observations relating to 88 male and 29 female patients aged 43 to 67 years. High informative capacity of the complex investigation including determination of gamma-globulin levels in blood serum, the albumin-globulin coefficient, the absolute count of lymphocytes and T-lymphocytes and lymphocyte migration inhibition in the test with tuberculin before and after the provocative tuberculin test was shown.
