目的 研究欧洲越桔花青素提取物对常压缺氧负荷小鼠抗缺氧能力的影响。

Methods The model of cerebral ischemia and anoxia in mice was established by decollation and ligating common bicarotid artery the effect of BVF on the survival time of the mice,and the time of catching their breath after mice decollated,and mouse brain capillary vessel permeability were observed.

采用小鼠断头、结扎双侧颈总动脉等脑缺血缺氧模型，观察苦菜总黄酮对脑缺血缺氧小鼠存活时间、断头小鼠喘息时间及脑毛细血管通透的

It has been thought that EPO plays a major role in high altitude hypoxiainduced erythrocytosis.

一般认为组织缺氧时EPO分泌增加可能是高原缺氧红细胞增多的原因。

Objective: As an important adaptation mechanism to hypoxia, erythrocytosis resulting from high altitude hypoxia maintains an adequate Oa delivery in blood.

目的：高原缺氧时红细胞增多，红细胞适度增多可以改善组织供氧，是缺氧习服-适应的重要机制之一。

The nestin in the cortex, hippocampus and extraventricular zone was significantly increased after HIBD, peaking at 7 days.

外源性bFGF可以明显增加新生大鼠缺氧缺血脑损伤后nestin蛋白表达，在缺氧缺血脑损伤后的神经元再生与修复中发挥一定保护作用。

One of these is a condition called hypoxia. It results from a lack of oxygen to the brain.

其中有一个情况称为组织缺氧，这种状况是由于大脑缺氧而引起的。

After hypoxia, the expression of BDNF and GDNF protein in NSC increas, and NYA can up-regulate the expression of BDNF and GDNF protein.

缺氧损伤后，神经干细胞内BDNF、GDNF蛋白表达增强，脑溢安能上调缺氧损伤神经干细胞内BDNF、GDNF蛋白的表达。

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。

Methods:Unsexed SD rats were randomly divided into shamming operation group and HIBD group.Rat models of acute brain hypoxic-ischemic were established.The expression of IL-1,IL-6 and IL-8 mRNA at days 1,3 and 7 respectively after injection was measured by rt-PCR method.

通过结扎左颈总动脉致大鼠脑急性缺血，后给8%氧气+92%氮气的混合气体致脑急性缺氧，建立大鼠脑急性缺血缺氧模型，在3个时相点采用rt-PCR方法测定假手术组、HIBD组脑组织中IL-1、IL-6和IL-8 mRNA含量变化。

AIM: The aim of this study is to investigate the possible role of potassium channel in hypoxic pulmonary vasoconstriction.

目的：以人离体肺动脉环缺氧张力变化为对象研究钾通道在缺氧性肺血管收缩发生中的作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
