Angiectasis, permeability were increased , inflammatory cell were transuded; The cardiac muscle injury conditions after hypoxia 4 h were similar with hypoxia 2h group, appeared lipid droplet, implied the oxidative metabolism of lipid got obstacle started from then; The cardiac muscle injuried conditions were got little improvement in hypoxia 6 and 8 hours team, mitochondria were increased and aggregatived, normal cell junction, sarcomere contract weaked; in hypoxia 10h group , mitochondria were increased and aggregatived obviously, a few glycogenosome were assembled, transverse tubule were expanded, all the changes may be the adaption of Gansu zokors in the hypoxia tolerance process to 4% hypoxia extent gradually.

在4%严重低氧耐受过程中，甘肃鼢鼠心肌超微结构在2h组出现血管扩张，通透性增加，有炎细胞渗出，异染色质边集；4h组心肌损伤状况与2h组接近，出现脂滴，提示脂类的氧化代谢在此时开始发生障碍，6和8h组心肌损伤状况逐渐好转，线粒体聚集增多，细胞连接正常，肌小节收缩较前有所减弱；10组线粒体增多聚集，线粒体脊增粗更为明显，少量糖原颗粒聚集，脂滴较前有所减少，横小管扩张增大变粗，出现了与能量代谢有关的结构适应性变化。

METHODS: While hypoxia-reoxygenation groups were not given any medicine intervention as control, the treatment of xionggui diwan 1×10-6mol/L was subdivided into xionggui diwan 1 × 10-6 mol/L + non-hypoxia and xionggui diwan 1 × 10-6 mol/L + hypoxia groups, and the treatment of xionggui diwan 10 × 10-6 mol/L was subdivided into xionggui diwan 10 × 10-6 mol/L + non-hypoxia and xionggui diwan 10 × 10-6 mol/L + hypoxia groups.

缺氧-复氧前后组分为两个亚组(即缺氧-复氧前、缺氧-复氧后)，均不进行药物干预；芎归滴丸1×10-6 mol/L组分为两个亚组(即芎归滴丸1.0×10-6mol/L+不缺氧组、芎归滴丸1×10-6mol/L+缺氧组)；芎归滴丸10×10-6mol/L组分为两个亚组(即芎归滴丸10×10-6 mol/L+不缺氧组、芎归滴丸10×10-6mol/L+缺氧组)。

Myspalax cansus (Rodentia, Myospalacinae, Myspalax)which lives on the loess plateau of our country. This unique underground rats life-long living under the cave, it developed many hypoxic tolerance protect mechanism to adapt its special circumstances at in organsall levels. In this study,we used Gansu zokor and SD rats (Sprague-Dawley)for the object, do serious hypoxia tolerance experiment, to explore the hypoxia tolerance extreme of Gansu zokor, analysis the difference hypoxia tolerance between Gansu zokor and SD rats at same oxygen concentration; The changes on their cardiac muscle organization structures in hypoxia tolerance process ; The expression of HSP70 between normoxic and hypoxic control in cardiac muscle organization of two animals , to find the relativity in all the results.

甘肃鼢鼠隶属啮齿目，鼢鼠亚科，鼢鼠属，是我国黄土高原特有地下鼠，由于终生营地下洞穴生活，使得甘肃鼢鼠发展出良好的低氧耐受保护机制，本研究以甘肃鼢鼠和SD大白鼠(Sprague-Dawley)为对象，进行低氧耐受实验，探寻甘肃鼢鼠的低氧耐受极限，比较二者低氧耐受的差异；以及低氧耐受不同时程，二者心肌组织显微和超微结构的变化差异；比较分析左心室组织中HSP70的表达变化和心肌耐受过程中组织结构变化的相关性。

hypoxia：缺氧

摘要: 缺氧(Hypoxia)是指氧气水平低于5%的一种状态,是正常的胚胎发生时自然存在的现象. 在器官形成期间,局部的缺氧环境似乎可作为血管生成的信号来刺激血管生成因子的产生,在一定程度上类似于在各种肿瘤细胞中诱导血管生成分子时伴随缺氧.

hypoxia：氧不足

呼吸系统-(1)不正常的肺功能. (2)对氧不足 ( hypoxia) 的敏感度下降. (3)对血碳酸过多 ( hypercapnia ) 的反应明显的下降.

hypoxia：组织缺氧

波士顿Dana-Farber癌症研究所(Dana-Farber Cancer Institute)的Bruce Spiegelman博士研究团队发现一个重要的代谢调控分子一PGC-1α,能感知血管中的低氧量及低营养量的危险性,随即促使血管生成以弥补氧气或营养成分的不足,这条路径很像组织缺氧(hypoxia)的现象.

hypoxia：低氧

(一)低氧(hypoxia)对人员的影响:低氧是威胁进入高原人员健康的最大"天敌". 由于高原地区海拔高,空气稀薄、缺氧、寒冷、昼夜温差大,因此进入这一地区的人员大都会出现不同程度的高原反应. 轻者恶心呕吐,头重脚轻,呼吸紧迫;重者头部剧疼,

hypoxia training：高地训练

那是一种国力与科学实力的宣扬,因此,运动科学被视为是选手竞技能力的加强,也就是在竞技运动中如何去赢的科学(陈全寿,1995);赢的科学包罗万象,诸如五大类增补剂(ergogenicaids)、高地训练(hypoxia training)、心智训练(mental training)等,
