The local angiokinetic phenomena contributing to the regulation of the microcirculation have been studied angiographically and hemodynamically. The angiograms obtained demonstrate the effect of prccapillary sphincter contraction in response to an increased pressure in the postcapillary segment in the form of a delayed arterial filling. Although several mechanisms may be involved, the results point to the existence of two common phases of action: first, an immediate period of angiokinetic reflex mechanism that is concerned with the local pressure regulation in the capillary bed involved and, second, a delayed period that is related to the volume regulation and appears to include an acute hyperaldosteronism. Both processes seem to be mediated through the glomic structures and present a definite interrelationship in their regulatory action on the microcirculation.
