Структурно-просторова перебудова вен малого кола кровообігу після резекції легень у собак

Abstract

Researches were made оn dogs, who were taken away 33о/о, 58% and 67% of lung parenchima. Ву means of functional and morphological methods it was establisted, that resection of 33 % of lungs is not accompanied with important changes of lung hemodinamics and morpho-functional state of lung veins. Taking off the 58% and 67% of lung parenhima was accompanied with а resistent disfunction of hemodinamics. ln early terms it was accompanied with increasing of the vessel walls tonus. lt was observed hyperealastosis, increasing of veins' walls thickness because of hypertrophy of their instriated muscular layer in the later terms. Increasing of simetry bifurcation level were established.
