拉西地平对高血压病患者血清氧自由基及空腹胰岛素的影响

应用拉西地平对３０例轻、中型高血压病（ＥＨ）患者治疗４周。观测治疗前后血清超氧化物歧化酶（ＳＯＤ）活力、脂质过氧化物（ＬＰＯ）及空腹胰岛素（Ｉｎｓ）水平。结果显示：（１）ＥＨ患者ＳＯＤ活力较正常人明显下降，ＬＰＯ水平明显升高（Ｐ＜０．０１）；服药后患者ＳＯＤ活力明显回升，ＬＰＯ含量显著降低（Ｐ＜０．０１）；（２）降压作用显著（Ｐ＜０．０１），治疗前后心率无明显变化（Ｐ＞０．０５）；（３）对空腹Ｉｎｓ，血糖，血脂无影响。表明拉西地平降压作用安全、有效，且具有抗氧自由基和保护ＳＯＤ活性的作用。

EFFECTS OF LACIDIPINE ON SERUM OXYGEN FREE RADICALS AND FASTING LEVELS OF INSULIN IN PATIENTS WITH ESSENTIAL HYPERTENSION

Thirty patients with mild to moderate essential hypertension had received four weeks treatment with Lacidipine and serum lipid peroxide(LPO), superoxide dismutase(SOD) and insulin levels were measured before and after treatment. The results showed: (1) there were decreased in SOD activity and increased Lpo content the patients group( P <0.01); (2) after treated with Lacidipine, the SOD acitvity increased and Lpo content decreased( P <0.01); (3) Lacidipine had obvious antihypertensive effect with no significant changes in heart rate; (4) Lacidipine had no significant effects on insulin, blood glucose and lipids. The results suggest that lacidipine is a safe and effective antihypertensive agent and can improve the metabolic balances in free radical system.
