Effect of 1-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine inhibitor on the reduction of one-kidney, one clip hypertension after unclipping in the rat.
The role of 1-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine in regulating blood pressure was studied in one-kidney, one clip hypertensive rats using 3-(N-n-octadecylcarbamoyloxy)-2-methoxypropyl-2-thiazolio ethylphosphate, which specifically inhibited the hypotensive activity of exogenously injected 1-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine. The blood pressure of rats with established hypertension produced by clipping one renal artery and contralateral nephrectomy normally decreases rapidly after unclipping the artery, but this rapid decrease was significantly inhibited by intravenous infusion of 3-(N-n-octadecylcarbamoyloxy)-2-methoxypropyl-2-thiazolio ethylphosphate. This shows that endogenous 1-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine participates in the rapid decrease of blood pressure after unclipping the kidney in one-kidney, one clip hypertensive rats.
