Abstract

A complex histologic and electronic-microscopic analysis of bronchial biopsy specimens was performed in various types of respiratory tract inflammation. Allergic inflammation of bronchial mucosa is accompanied by development of perivascular edema with malfunction of endothelial cellular activity, epithelial destructions and desquamations that are significant pathogenetic factors of bronchial hyperreactivity. Nonallergic inflammatory process is accompanied by subepithelial and perivascular fibrosis, which leads to irreversible bronchial obstruction. Atrophy sites of epithelial layer alternate with squamous cell metaplasia, which reflects dysregeneration processes developing in the respiratory tract.
