[Clinico-morphological comparisons in the laser therapy of chronic bronchitis patients]

The article presents results of endobronchial treatment with low-intensity laser in 56 patients with chronic non-obstructive bronchitis (CNOB). Irradiation was carried out in 5-7 positions. Course of the treatment consisted of 4-6 seances. 14 days after the start of the treatment patients showed improvement of general condition, normalization of body temperature, reduction of cough, disappearance of endoscopic inflammatory changes in bronchial mucosa. Morphometrical data evidenced activation of proliferative processes and normalization of bronchial secretion which indicated increase of tissue metabolism. Cytological study revealed qualitative improvement of epithelial cover. Low-intensity laser is noted to be highly effective in the treatment of patients with CNOB, especially in the early stage of pathological process.
