Serioangiographic study of renal cortical necrosis induced by administration of estrin and vasopressin in rats.
We report a serioangiographic method in rats which permits assessment of the course and dimensions of the renal arteries, the durations of the arterial and venous phases, and the intensity and uniformity of the renal parenchymal filling. The procedure was employed to study the mechanism by which administration of vasopressin to rats pretreated with estrin leads to renal cortical necrosis. The pathogenetic significance of the spasm localized on the larger renal arteries was proved directly; the possible role of the arteriovenous shunt in the development of the renal ischemia was excluded.
