[Preliminary study on protecting effect of two kinds of Chinese medical herbs on changes of three physiology systems in suspended rats].

Objective. To observe the protecting effect of two kinds of Chinese medical herbs on changes of blood circulation, muscle and skeletal systems in tail suspended rats. Method. Changes of blood circulation, muscle and skeletal systems in tail suspended rats (n=15), Chinese medical herb group 1 (n=15) and Chinese medical herb group 2 (n=15) after 30 d tail suspension were compared with those in control group rats (n=15). Result. Two kinds of Chinese medical herbs have obvious effect on improving the condition of blood circulation, and have some effects on improving the muscle and skeletal systems in tail suspended rats. Conclusion. Chinese medical herbs have a good prospect of being used in space flight, and further studies are needed.
