on­ cepts, as well as the development of new modalities of pharmacotherapy will have to be discussed. The topic addressed by the 1990 Gargellen Conference: Endothelial Mechanisms of Vasomotor Control, clearly is of interest for both basic scientists and clinicians. It has been the aim of the organizers, the S978-3-642-72463-3978-3-642-72461-9

Endothelium and blood flow mediated vasomotion in the conscious dogendothelium, through elaboration of constricting factors, e. g., endothelin, can also induce potent vasoconstriction. In the conscious animal endothelin elicits markedly differing degrees of vasoconstriction among the various regional vascular beds.

Thus, endothelial dysfunction is an early and specific marker of reperfusion injury preceding neutrophil involvement and cardiac necrosis. Superoxide radicals appear to play a key role in the decreased EDR observed early after reperfusion.

Establishment of various animal models to elucidate mechanisms related to various stages of ischemic heart disease are needed.

Blood flow and optimal vascular topography: role of the endotheliumol value but was restored towards 3, both by basal and by acetylcholine-stimulated EDRF activity. In contrast, endothelin-1 caused a dose-dependent reduction in the junction exponent from its optimal value 3. This suggests that the endothelium helps to optimise microvascular function through EDRF but not endothelin-1 release.
