本实验采用头低位20°悬吊方法,造成体液头向分布,观察4组(对照组,头低位悬吊3、7、15天组)兔的脑超微结构和显微结构的变化,结果表明悬吊后兔脑出现明显的微血管组织结构的变化,这些变化在悬吊后第三天最明显,15天时有恢复趋势。 In this experiment, head low 20 ° suspension method, resulting in head to body fluid distribution, observed in 4 groups (control group, the first low hanging 3,7,15 days group) rabbit brain ultrastructure and microstructure changes, the results The results showed that there were obvious changes of microvessel structure in the rabbit brain after suspension. These changes were the most obvious on the third day after suspension and tended to recover on the 15th day.
