[Coefficient of capillary filtration in the skeletal muscles during changes of their hemodynamics].
In acute experiments on cats using the method of extracorporeal blood volumometry, the capillary filtration coefficient (CFC) in the skeletal muscle did not correlate with induced changes of arterial pressure (65-280 mm Hg), venous pressure (0-30 mm Hg) and the induced changes of the blood inflow (75-150%). A negative functional relationship was found between blood flow and CFC in the skeletal muscle in the blood flow was less than 75% of the initial level. This phenomenon is interpreted as a metabolic dilatation of the precapillary sphincters caused by limitation of the blood supply of the tissue under study.
