复方丹参注射液对单侧输尿管结扎大鼠肾内局部血管紧张素Ⅱ的作用

Effects of Compound Danshen Injection on Local Angiotensin Ⅱ in Rat kidney with Unilateral Ureteral Obstruction

目的 :观察复方丹参注射液及苯那普利对梗阻性肾病大鼠的保护作用。方法 :采用单侧输尿管结扎的方法制备间质性肾炎模型 ,分别投以复方丹参注射液及苯那普利 ,检测肾组织中血管紧张素Ⅱ、内皮素含量及血管紧张素转换酶活性。结果 :复方丹参注射液组大鼠肾组织中血管紧张素Ⅱ含量为 42 .0 3± 13 .95 pg/mg ,较病理组 80 .19± 2 7.31pg/mg明显减少 ;苯那普利组为 32 .5 3± 8.0 7pg/mg ;肾组织中血管紧张素转换酶活性、内皮素亦有类似结果。 结论 :复方丹参注射液及苯那普利能有效地抑制梗阻性大鼠肾组织中血管紧张素转换酶的活性 。

Objective:To investigate the protective effects of Compound Danshen Injection and Benazepril on rats with obstructive nephrosis.Methods:The interstitial nephritis model of rat was established by ligating unilateral ureter. The model rats were given drug Compound Danshen Injection and Benazepril, respectively. The levels of angiotensin Ⅱ (Ang Ⅱ), endothelin (ET 1) and the activity of angiotensin converting enzyme (ACE) in renal tissues were measured. Results: The level of angiotensin Ⅱ of Compound Danshen Injection group was 42.03±13.95pg/mg lower that of pathologic group (80.19±27.31pg/mg). The level of Benazepril group was 32.53±8.07pg/mg. There were significant differences among them. The measuring results of ACE and ET 1 were similiar to that of Ang Ⅱ.Conclusion: Compound Danshen Injection and Benazepril can effectively inhibit the activity of ACE and decrease the levels of Ang Ⅱ and ET 1.
