Effect of Chronic Treatment of Propranolol on Lipid Metabolism in Spontaneously Hypertensive Rats (SHR)

[摘要] References(30)Cited-By(3)The effects of propranolol on lipid metabolism were studied in spontaneously hypertensive rats (SHR). Male SHR and corresponding Wistar Kyoto rats (WKY) were used at 5 weeks of age. The SHR were given 10 mg/kg/day of dl-propranolol·HCI by gavage for 10 weeks. Body weight gain in untreated SHR and propranolol-treated SHR (SHR-P) groups were low, as compared with those of the WKY group. Total cholesterol, phospholipid and total lipid of the serum and liver in the SHR-P group were higher than in the SHR group. In the early weeks of treatment, serum triglyceride and non-esterified fatty acid levels in the SHR-P group were slightly lower than those in the SHR group. Aortic lipid levels in the SHR-P group were lower than those in the SHR group. During the later weeks of treatment, blood glucose level in the SHR-P group was higher than in the SHR group. The serum immunoreactive insulin value in the SHR-P group was slightly lower than in the SHR group. These results may suggest that propranolol inhibits hormone-sensitive lipase activity in the early weeks of treatment and influences cholesterol biosynthesis and/or catabolism.
