目的:研究黄芪总黄酮(totalflavonoidsofastragalus,TFA)对缺血再灌注损伤的防护作用。方法:应用家兔失血性休克/再灌注模型(shock/repercusion,S/R),观察损伤后血浆中一氧化氮(nitricox ide,NO)代谢终产物亚硝酸盐(NO2)的变化及TFA和磷脂酶A2阻断剂氯喹(Chlq)治疗对其的影响。结果:数据表明S/R后24h内血浆中NO2含量,与血pH值及二氧化碳总量(TCO2)下降呈正相关;TFA和Chlq可在一定程度上阻断NO的减少,且对维持体内酸碱平衡有一定作用。结论:TFA对缺血再灌注损伤具有防护作用。 |

Objective: To study the protective effect of total flavonoids of Astragalus (TFA) on ischemia/reperfusion injury. Methods: Change of nitrite (NO 2), the terminal product of nitric oxide (NO) metabolism, and the effect of TFA and chloroquine (a phospholipase A 2 inhibitor) on it were observed with hemorrhagic shock/reperfusion injury (S/R) rabbit model. Results: Plasma NO 2 content was positively correlated with blood pH and total carbon dioxide content lowering. TFA and chloroquine could block the decrease of NO in certain degree and might have some effect on maintaining acid base balance of body. Conclusion: TFA has protective effect on ischemia/reperfusion injury. |
