摘要: 背景与目的: 观察芎芍胶囊含药血清对人脐静脉内皮细胞(human umbilical vein endothelial cell,HUVEC) 一氧化氮(nitrogen monoxidum,NO)、诱导型一氧化氮合酶(inducible nitricoxide synthase,iNOS)、内皮型一氧化氮合酶(endothelial nitricoxide synthase,eNOS)表达的影响,探讨芎芍胶囊促血管新生的作用机制。 材料与方法: 不同芎芍胶囊药物浓度的含药血清(分为4.17、8.33和16.66 mg/ml共3组)培养HUVEC细胞24 h后,比色法检测培养液中NO、iNOS的含量,RT-PCR检测HUVEC细胞中iNOS、eNOS的表达。 结果: 4.17 mg/ml含药血清组培养上清液中NO含量较对照组增加(P<0.01);4.17和8.33 mg/ml含药血清组iNOS含量较对照组增加(P<0.01)。RT-PCR结果显示,4.17 mg/ml含药血清组HUVEC细胞的eNOS mRNA和iNOS mRNA的表达均增加(P均<0.01),8.33和16.66 mg/ml组HUVEC细胞的eNOS mRNA和iNOS mRNA表达均减少(P均<0.01)。 结论: 4.17 mg/ml芎芍胶囊含药血清组促进血管新生可能与增加iNOS、eNOS mRNA表达,促进NO合成与分泌有关。

Abstract: BACKGROUND AND AIM: To explore the mechanism of xiongshao capsule on inducing angiogenesis by measuring its effects on nitrogen monoxide(NO), inducible nitric oxide synthase(iNOS) and endothelial nitric oxide synthase(eNOS) in human umbilical vein endothelial cells. MATERIALS AND METHODS: Serologic pharmacology method and reversed transcriptive polymerase chain reaction(RT-PCR)assay were used to measure the effects of serum containing different concetrations of xiaongshao capsule(4.17, 8.33 and 16.66 mg/ml, respectively) on NO and iNOS secretion and expressions of iNOS and eNOS mRNA. RESULTS: Serum containing 4.17 mg/ml xiaongshao capsule could promote the secretion of NO(P<0.01), whereas the concentrations of 4.17 and 8.33 mg/ml could promote the secretion of iNOS(P<0.01). RT-PCR showed serum containing 4.17 mg/ml xiaongshao capsule up-regulated the mRNA expressions of eNOS and iNOS significantly(P<0.01),and the concentraions of 8.33 and 16.66 mg/ml down-regulated the mRNA expressions of eNOS and iNOS significantly(P<0.01). CONCLUSION: The angiogenetic effect of serum containing 4.17 mg/ml xiongshao capsule may be attributed up-regulating the expressions of iNOS and eNOS mRNA and promoting nitrogen monoxid synthesis and secretion.
