摘要
总结了近年来本实验室有关模拟失重对心血管功能影响及下体负压对抗作用的研究。讨论了模拟失重致立位耐力不良的机理可能与心血管功能降低、脑血流降低及内分泌改变等有关 ,以及采用数学模型方法探讨失重致立位耐力降低机制的作用意义。
Studies on effect of simulated microgravity on cardiovascular function and counter effect of lower body negative pressure(LBNP) in recent years were summarized. The mechanism of simulated microgravity induced orthostatic intolerance may involve the reduction of cardiovascular function and cerebral blood flow, and endocrine changes. The significance of mathematical model in the study of mechanism of microgravity induced orthostatic intolerance was also discussed. The counter effect of LBNP was emphasized.
