Koptev M. Topography and morphofunctional characteristics of structural elements of lungs in norm and in experimental stress

A thesis is devoted to the study of peculiarities of lungs' shape and structure of white rats normally and after influence of experimental immobilization stress. Performed complex investigation of morphological and functional changes of lungs after influence of immobilization acute and chronic stress by anatomical, histological, histochemical and morphometric methods has shown that an acute immobilization stress causes a development in rats lungs prominent destructive changes, hemorrhagic phenomena and microcirculation deterioration at the beginning of the stage of an anxiety. It has been established after influence of chronic immobilization, besides destructive phenomena and deteriorations of hemomicrocirculation in lungs and bronchi there is an inflammatory infiltration of pulmonary tissue and bronchial walls. Comparative analysis has shown after action of acute immobilization stress in lungs and bronchi in rats prominent hemorrhagic manifestations predominate, while as a consequence of chronic influence things of emphysema prevail.
