Reactive vasodilation
WebVasodilation is the archetypal function of the endothelial cell and the discovery of paracrine-dependent vasorelaxation by endothelium-derived production of the gaseous mediator nitric oxide (NO) was revolutionary. NO mediates its regulatory vasorelaxing effects through guanilyl cyclase activation.

Webblood re-enters. This response is called reactive hyperemia. Depending on the length of occlusion, paracrine metabolites can accumulate at higher than normal levels, resulting in a significant trigger of vasodilation when blood flow resumes. This rapid increase can cause an inflammatory response that results in more cellular damage. WebParticipants completed a comprehensive diet questionnaire (DHQIII, NIH). Peripheral and central blood pressures were measured via the SphygmoCor system (AtCor Medical). …
