[Specific and nonspecific bronchial and regional lymph nodal lesions as a manifestation of synergism in the lymph epithelial system in pulmonary tuberculosis].

The lung and lymph nodes were examined in 130 patients aged 19-70 years, who had been operated on at the Department of Surgery, Saint Petersburg Research Institute of Phthisiology, for pulmonary tuberculosis. The immunopathological changes have close correlations in the bronchi and pulmonary respiratory parenchyma. This gives grounds to regard the lung and lymph nodes jointly as the organ of local immunity (sui generis) and to suggest that there is a synergism of immune reactions.

[Pathological characteristics of drug-resistant fibrocavernous pulmonary tuberculosis].

A histological examination of the pulmonary and bronchopulmonary lymph nodes was made in 47 patients treated surgically for fibrocavernous pulmonary tuberculosis. The speed of immunopathological reactions development is the main reason of differences between drug-resistant and drug-sensitive primary tuberculosis. Formation of cellular immunity in drug-resistant tuberculosis has all necessary morphological prerequisites both in the lungs and lymph nodes but their realization is delayed.

[Interaction of precursors of secretory proteins and components of a cell-free protein-synthesizing system with phospholipid membranes].

Translocation of eucaryotic secretory proteins across the phospholipid membrane containing, no protein components has been studied on the model system. The level of translocation was found to depend critically on physical and chemical properties of membranes. It was found that the cell-free system components can exhibit membrane activity.
