title: Different excretion pattern of urinary PGE2 and 6-keto-PGF1 alpha in two kidney-one clip Goldblatt rats.
abstract: Changes in blood pressure and 24 hour urinary excretion of PGE2 and 6-keto-PGF1 alpha have been studied during ten weeks after renal artery clipping or sham operation in rats. From the second week on, systolic blood pressure was significantly increased in the two kidney-one clip rats as compared to controls. Maximal differences were reached in the 10th week after the operation (145 +/- 8 vs 116 +/- 3.2 mm Hg; p less than 0.001). Urinary PGE2 levels showed markedly elevated values versus controls from the 6th week on (p less than 0.001). However, no significant changes in urinary 6-keto-PGF1 alpha excretion were observed between the groups during the whole experimental period. These findings suggest that renal PGE2 may be involved in the pathophysiology of blood pressure control in the two kidney-one clip model, whereas, 6-keto-PGF1 alpha seems not to be altered after renal artery clipping.
