大花红景天对悬吊大鼠和职业运动员的防护作用(英文)

Protective Effects of Rhodiola Crenulata on Rats Under Antiorthostatic Position and Professional Athletes

红景天是一种适应原样的药物,具有增强机体非特异性耐力的功能。我国大约有七十多种红景天,主要分布在西北、华北和东北地区。部分红景天的药理作用已有不少报导,但涉及大花红景天的较少。本文介绍大花红景天两方面的研究结果:1.大花红景天对模拟失重条件下(尾吊大鼠)动物机体的部分生理反应的影响;2.健康人(职业运动员)服用后对心肺功能等指标的影响。实验结果表明,大鼠在连续7天悬吊后出现了体重降低,腓肠肌萎缩,胸腺萎缩,腓肠肌蛋白含量降低等不良反应,能被大花红景天明显地纠正。健康人连续服用75天后,提高他们运动成绩,改善了在自动跑台上作功总量,显著提高运动时的最大耗氧量和分钟通气量,而且没有发现不良反应。这表明该药安全无毒,是一种对机体有良好效用的草药。它应该有更广泛的应用前景,特别在提高航天员对多种环境不良因素耐力方面具有应用可能性。

This paper reported the results of pharmacological studies on R.crenulata in head down tilted rats and 11 professional athletes.The results showed that R.crenulata from the western region of Sichuan province is a non-poisonous and effectiveherb.It protected the head down rats from atrophy of soleus muscle and thymus,avoidedexcessive decrease of soleus myoprotein content and body weight.Under conditions of phy-sical stress on a motor-driven treadmill,athletes who took R.crenulata had greater Ve,Vo_(2max),and higher ability of doing work than the controls.After medication for 75 days,their sport records raised significantly without any discomfort.It demonstrated that R.crenulata has favorable effects on organisms and has a good prospect of further use in astro-nauts.
