[Tuberculin-cytochemical test in the differential diagnosis of silicosis and silicotuberculosis with intrathoracic adenopathy].

Cytochemical tuberculin-associated shifts along with their prognostic evaluation were studied in 30 patients with silicosis and silicotuberculosis with intrathoracic adenopathy. The study revealed that a decrease of alkaline phosphatase activity of neutrophils, alpha-glycerophosphate dehydrogenase and succinate dehydrogenase lymphocytes could serve as an early indicator of tuberculosis process in the pulmonary tissue and intrathoracic lymph nodes.
