[The functional activity of class-I and -II HLA antigens in pulmonary tuberculosis].

The paper presents evaluation of HLA-system functional activity in patients with pulmonary tuberculosis and bronchial asthma by expression of class I and II antigens and beta2-microglobulin level in peripheral blood cell elements. Tuberculous patients had reduced production of beta2-microglobulin in the cell elements. Long-term chemotherapy aggravated the above abnormality.

[Effects of laser therapy on immunity in patients with bronchial asthma and pulmonary tuberculosis].

In bronchial asthma alone and combined with active pulmonary tuberculosis there are marked shifts in immune system (diminished mature T-cell and suppressor subpopulation of T-lymphocytes) resulting in disordered immunoregulatory subpopulation relationships. Also, B-system immunity responded with hyperfunctional activity (increased count of B-lymphocytes and polyclonal gammaglobulinemia). As conventional methods fail to normalize the shifts, an adjuvant laser immunocorrection was tried.
