[Coefficient of capillary filtration in the skeletal muscles during changes of their hemodynamics]

Abstract

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.
