Analysis of Heart Rate Variability during Acute Exposure to Hypoxia. 急性缺氧条件下的心率变异性分析
Conclusion Dimethoate has adverse effects on cardiovascular function of rats after acute exposure. 结论：接触乐果短时间内可导致大鼠心血管系统功能的改变。
For all species tested, the immediate effect of acute exposure to high concentrations of NF3 is extensive methemoglobin formation with subsequent hypoxia. 对于测试的所有物种，急性暴露于高浓度NF3的直接影响是大范围高铁血红蛋白形成和并发的组织缺氧。
Objective The aim of this study was to determine whether psychomotor performance and visual reaction time were affected by acute exposure to mild or moderate hypoxia. 目的研究急性轻、中度缺氧暴露对人的心理运动及视觉反应时的影响。
In the acute exposure group,fertilization time was 140 days after irradiation with 2.OGy,and the spermatogonia were mainly injured. 2.
