Immune status was examined in 231 patients facing pneumoconiosis and coniotuberculosis so as to observe a dependence on pneumoconiosis type (silicosis, electric welder's pneumoconiosis), severity of the process, activity of tuberculosis. Markedly changed T and B immunity, having already appeared at initial stage of the disease, were revealed. Those changes due to the tuberculosis activity were characterized by lymphocytosis, marked functional immaturity of T lymphocytes, depressed B lymphocytes count, elevated serum Ig level.

The impact of enterosorption on the morphology of peripheral red blood cells was examined in patients with coniotuberculosis and pulmonary tuberculosis by using scanning electron microscopy. Enterosorption was found to promote decreases in the proportion of abnormally changed cellular elements and increases in normal cells, which confirms the stimulating and antitoxic effects of this treatment.

Positive DNGG test is a nonspecific test for dust content, anthracosilicotic induration and coniotuberculosis of thoracic lymph nodes. As additional to clinicoroentgenological examination of thoracic lymph node coniotuberculosis of occupational and non-occupational origin.

Patients exposed to quartz dust had some special morphological picture of affected lymph nodes: periadenitis, dust caseosis and tubercula in the presence anthracosilicosis sclerosis. Silicotuberculous broncho-adenitis in silicosis patients is characterized by solitary lesions of the lymph nodes, bronchi, rare dissemination to the lungs.

The studied group included 35 patients with suspected pneumoconiosis, 75 patients facing the 1 grade of pneumoconiosis, 43 coniotuberculosis patients and 43 patients with dust bronchitis. Active LP was demonstrated, values and intensities of its stages depended on the origin and severity of disease.
