目的探讨维拉帕米对单侧输尿管梗阻(UUO)大鼠肾间质纤维化的影响。方法将24只大鼠随机分为对照组(即假手术组)、UUO模型组、维拉帕米治疗组,采用单侧输尿管梗阻模型,术后8天观察梗阻肾组织病理改变,比色法测定肾组织羟脯氨酸(HYP)、丙二醛(MDA)和超氧化物歧化酶(SOD)含量,并应用放射免疫法检测血浆和肾组织内皮素-1(ET-1)的含量。结果与对照组比较,模型组肾组织HYP和MDA含量明显升高,血浆和肾组织内皮素-1含量明显升高,肾组织SOD含量显著下降(P<0.01),维拉帕米治疗组与模型组相比,肾组织HYP和MDA含量明显下降,血浆和肾组织内皮素-1下降,肾组织SOD含量显著升高,差异均有显著性(P<0.05)。结论维拉帕米能减少单侧输尿管梗阻大鼠脂质过氧化物的产生,降低血浆和肾组织内皮素-1的含量,增加抗氧化酶的含量,从而阻抑UUO大鼠肾间质纤维化。 |

ObjectiveTo investigate the effect of varapamil on kidney of rats with interstitial fibrosis after unilateal ureteral obstruction(UUO).MethodsTwenty-four rats were randomLy assigned to shame operation group(normal group),UUO group and varapamil treatment group after unilateral ureteral obstruction.Renal tissues were examined by light microscopy 8 days after operation.Hyd -roxyl puamino acid (HYP),Malondiadehyde(MDA) and superoxide dismutase(SOD) content were measured.Endothelin (ET-1) was measured by radioimmunoassay.ResultsIn comparison with shame operation group,HYP and MDA content significantly increased,the level of plasmic and renal endothelin-1 significantly increased,SOD content significantly decreased(P<0.01).In comparison with UUO group,varapamil signicantly ameliorated what had mentioned (P<0.05).ConclusionsVarapamil can suppress renal interstitial fibrosis by reducing lipid peroxidation production and reducing the level of plasmic and renal endothelin-1 and improving antioxidative enzyme contents. |
