Heterogeneous behavior of the canine arterial and venous wall. Importance of the endothelium.

abstract：:When exposed to an increasing transmural pressure, middle cerebral arteries of the cat exhibit reduction of internal diameter which is mediated by vascular muscle cell depolarization. This laboratory has recently demonstrated that this "pressure-induced" activation is dependent upon the presence of an intact endotheli...
