WebApr 1, 2002 · Insulin-mediated capillary recruitment appears to be independent of changes in bulk blood flow to the limb in both rats and humans, particularly if physiologic levels of insulin are used ( 33 ). Measurement of capillary exposure (or nutritive flow) in anesthetized rats was assessed using 1-methylxanthine (1-MX) metabolism. WebCapillary recruitment by insulin occurs before stimulation of skeletal muscle glucose uptake, and can be mediated by doses that do not stimulate muscle glucose uptake . It thus is likely that endothelially derived nitric oxide is stimulated via insulin directly, rather than via an intermediate. Furthermore, the rapidity of the response ... clocks wellington
