药物对高原人体运动血液流变学的干预效应

目的探讨药物对高原人体运动前后血液流变学的影响。方法对进驻海拔4100m高原20天的40名健康青年随机分为红景天组、乙酰唑胺组、西氏胶囊组和对照组，每组10人，在安静时、服药前、后及踏阶运动后分别检测红细胞压积(HCT)、血液粘度(η

Effects of Drugs on Hemorrheology Before and After Exerctse at High Altitude

Objective:To study the effects of drugs on hemorrheology before and afetr exercise at high altitude.Methods:The 40 healthy youth were randomly divided into 4 groups (Rholida,Acetazolamide,Xi′s capsule and Control group),who have stayed high altitude (4100m) for 20 days to determine their HCT,ηb,ηp,ηr,IR,TK,VAI and TFL at rest state,before and after taking drugs,and after stair-exercise.Result:All those indexes decrease of after stair-exercise (P<0.05 or 0.01).After taking drugs for 6 days,the Rholida group′s ηb,ηp,ηr,IR,TK and VAI decreased,the Xi′s capsule group′s indexes except HCT decreased,and all those indexes of Actazolamide group decreased (P<0.05 or 0.01),but there is no statistics meaning in Control group(P>0.05).Before stair-exercise,the ηb,ηp,IR,TK,VAI and TFL decreased afetr taking drugs,but after stair-exercise,the ηb,ηp decreased notably in three drug groups (P<0.05 or 0.01).Conclusion:Rholida,Acetazolamide and Xi′s capsule could improve the tissne microcircultion and hemorrheology at altitude.
