失重可以引起人体一系列生理功能紊乱,许多学者认为这些紊乱和失重时的脑微循环和脑功能有关,但此方面的报道甚少。因此本实验采用兔头低位20°悬吊方法。模似失重所引起的体液头向分布和低动力,观察53只兔在悬吊期间脑微血管的显微和超微结构、血中的cAMP和cGMP及脑电超慢涨落的变化。结果表明悬吊后
Weightlessness can cause a series of physiological disorders in the human body. Many scholars believe that these disorders are related to brain microcirculation and brain function when weightless, but there are few reports in this regard. Therefore, this experiment uses rabbit head low 20 ° suspension method. The distribution and low dynamics of body fluids caused by simulated weightlessness were observed. Microscopic and ultrastructural changes of brain microvessels, cAMP and cGMP in blood and ultra-slow fluctuations of EEG were observed in 53 rabbits during suspension. The results show that after suspension
