[The adaptive-compensatory reactions of the pulmonary microcirculatory bed in experimental pneumonia].

Pulmonary microcirculation was studied in anesthetized interbred male cats with acute pneumonia in acute experiments by the method of intravital microscopy. Due to the reticular structure of the lung microcirculatory channel and the change of the direction of the blood flow in microvessels stretching to the focus of inflammation, collateral circulation developed rapidly and facilitated redistribution of the blood flow in the pulmonary lobe involved in the inflammation.
