中药在改善模拟失重兔主要脏器形态学变化中的作用

通过实验探讨中药作为一种新的防护措施的可能性。实验动物为53只白兔,用头低位悬吊方法模拟失重,时间7天。实验前将兔分为四组:对照组,悬吊组,川芎组,丹黄组,实验中分别喂水或喂中药。实验后取脑、心、肺、肾、腹主动脉、比目鱼肌等6个脏器制片,进行组织学观察。结果是两种中药均有改善模拟失重兔主要脏器血循环和组织结构的作用,丹黄合剂的作用优于川芎。这说明中药作为一种新的防护措施是有希望的。

THE EFFECTS OF CHINESE HERB MEDICINE IN IMPROVING MORPHOLOGICAL STRUCTURE OF INTERNAL ORGANS IN SIMULATED WEIGHTLESSNESS RABBIT

The purpose of this experiment is to investigate whether some kind of Chinese herb medicine has the effect of decreasing the morphological changes of internal organs in rabbit under simulated WL. 53 rabbits are exposed to headdown suspension to simulate the influence of WL. The rabbits are divided into four groups: contrast group, head-down suspension group, Chuan-Qipng group and Dan-Huang group (Chuan-Qiong, Dan-Huang, names of Chinese medicine). Morphological changes of the brain, lungs, heart, kidney, aorta and so-leus muscle are observed. The result showes the Chuan-Qiong (CQ) or Dan-Huang mixture (DH) has effects of improving the conditions of circulation and structure of organs in SWL rabbits, and the effect of DH seem to be better than that of CQ. So the Chinese herb medicine may have a good prospect of being used in space flight.
