title: Increased renal prostanoid synthesis after unclipping the one-kidney, one-clip hypertensive rat: effect of renal denervation.
abstract: Renal denervation of hypertensive one-kidney, one-clip (1K, 1C) rats resulted in a minor fall in blood pressure (216, s.e.m. = 4, to 182, s.e.m. = 4, mmHg) 24 h later, which returned to predenervation levels with 1 week. Subsequent unclipping led to a similar fall in blood pressure in denervated (202, s.e.m. = 4 to 142, s.e.m. = 3) and sham-denervated (211, s.e.m. = 5 to 147, s.e.m. = 4) rats. Unclipping also resulted in a marked rise in urinary PGE2 and 6-keto PFG1 alpha in both denervated and sham-denervated animals. It appears that 1K, 1C hypertension, 8 weeks after clipping, is only slightly dependent on renal nerves. Unclipping results in increased renal synthesis of PGE2 and PGI2 which is not dependent on intact renal innervation.
