Ultrastructural aspects of reactivity of regional lymph nodes on pulmonary inflammation and following endobronchial laser therapy.

The purpose of this study is the evaluation of reactivity of the regional lymph nodes on infectious-destructive process in the lung, and the efficacy of different therapeutical tactics. Examination of 7 regional lymph nodes from 7 patients with pulmonary inflammation showed marked manifestations of acute lymphadenitis. Generally speaking, these lymph nodes were enlarged and manifested signs of severe cell alteration and damaged processes of lymphocyte reproduction and migration. In 10 lymph nodes from 10 patients with similar pulmonary pathology receiving the same therapeutical measures combined with laser therapy course, neither lymphadenitis nor cell alteration signs were found. The results indicate the high plastic abilities of the lymph nodes and the efficacy of laser biostimulation.
