abstract = {AIM: To examine protective effects of lovastatin, an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, on endothelial dysfunction induced by a single intravenous injection of natural low density lipoprotein (n-LDL) and analyze the possible action mechanism of lovastatin.
METHODS: Rats were treated by intraperitoneal injection with lovastatin at dose of 2 or 4 mg/kg body weight once daily for 7 d, and on d 6 a single injection of n-LDL 4 mg/kg was given by sublingual vein. Forty eight hours after injection of n-LDL, the descending thoracic aorta of rats was taken. Acetylcholine (ACh)-induced endothelium-dependent relaxation (EDR) and sodium nitroprusside (SNP)-induced endothelium-independent relaxation of aortic rings were examined in vitro. Malondialdehyde (MDA), nitric oxide (NO), and activity of superoxide dismutase (SOD) as well as level of lipid in serum were analyzed.
RESULTS: A single injection of n-LDL inhibited ACh-induced EDR compared with normal control group (maximal relaxation rate: 69.5 %+/-1.2 % vs 91.0 %+/-1.2 %, P},
