查询词典 hypoxia

Results In hypoxia control group, the time for OPS to disappear was (186±16) seconds; HIP occurred in all slices within about 10 minutes of hypoxia and lasted for (113±16) seconds. When normal ACSF superfusion was restored, the rates of OPS recovery and OPS amplitude were 25% and (30±23)% respectively.

结果 缺氧组OPS消失时间为(186±26)s，在缺氧10min左右，均出现HIP，持续时间为(113±16)s；恢复供氧后，OPS恢复率和恢复幅度分别为25%和(30±23)%。

By superfusion of ET-1,the hypoxia-induced decrease in RPF was remarkably potentiated and the occurrence of pacemaker arrest was shifted to an earlier time. The h3,poxia-induced effects could be effectively attenuated after pretreatment with BQ-123,implying the role of endogenous ET-1 release in hypoxia-induced effects.

ET-1可显著加重缺氧所致的RPF降低，使起搏细胞停跳时间前移；而以ET*受体阻断剂BQ-123预处理窦房结标本后，则能有效地缓解缺氧对起搏细胞的效应，提示内源性ET-1的释放在缺氧效应中的作用。

The result indicates that Bassia rapa L. 65%, 95% alcohol extract and water extract can prolong the survival time of mice in hypoxia under ordinary pressures significantly. It can also prolong the survival time of mice with acute cerebral ischemia and sodium nitrite significantly, and increase the number of erythrocytes and the content of hemoglobin. It demonstrates that Bassia rapa L. extract has anti-hypoxia activity.

结果表明，芫根水提取物、65%乙醇提取物及95%乙醇提取物均能明显延长模型小鼠在常压缺氧、急性脑缺血性缺氧及亚硝酸钠中毒时的存活时间，并可增加外周血象中红细胞数与血红蛋白含量，显示芫根提取物具有抗缺氧活性。
