The results indicate:(1). The site of pulmonary vasoconstriction induced by hypoxia may be precapillary.

实验结果表明：①缺氧所致的成年山羊肺动脉压增高，可能是毛细血管前阻力血管收缩的结果。

He invented the first successful high-altitude pressure suit in the 1930's, so he wouldn't pass out from lack of oxygen when he was thousands of feet up in the air.

他想打破以往的飞行高度纪录，于是在1930年成功地发明了第一件高空压力服，这使他在几千尺的高空上不会因缺氧而昏迷。

By now, it has not been proved that pulmonary artery has ramus communicans.

到目前为止，还没有充分的证据证明肺动脉存在交通支，加之CPB时的无搏动性血流灌注，因此，相对来说肺脏处在"高温与缺氧"状态。

Cerebral ischemia or hypoxia resulted from low perfusion plays a central role in secondary brain injury.

灌注不足导致的缺血缺氧是继发脑损伤的中心环节。

The expression of NOSⅢ mRNA was detected semiquantitatively by reverse transcription-polymerase chain reaction.③Immun ocytochemistry was used to detect the expression of NOSⅢ protein.

将原代培养的CAEC进行缺氧1 h，复氧2、6、12和24 h，用逆转录-聚合酶链式反应和免疫细胞化学方法检测NOSⅢmRN A和蛋白质表达的变化。

But the tetragonal phase in the surface region transforms easily to monoclinic phase when the samples are exposed to air.

这可能是由于在缺氧条件下样品表面形成了一种具有氧空位的扭曲结构，这种结构可以阻止四方相到单斜相的转变。

The increase of leptin expression and the decrease of adiponectin expression inpreeclampsia are closely correlated with hypoxia of trophoblast.

结论子痫前期中瘦素表达的增加与脂联素减少与滋养细胞缺氧是密切相关的。

It is suggested that the ultramicroscopic pathological changes of parietal lobe of cortex during hypobaric anoxia are consistent with the changes of morphology and enzymic activity.

大鼠在不同高度急性缺氧时所发生的一系列超微病理学变化与组织形态学及酶活性变化一致，且表现得更明显，也是各种生理学紊乱、酶活性降低及组织学改变的基础。

24H treatment group compared with 24h model group: the density of light of HSP70 of the group increased and which of TGF-β〓, is not different with the model group; the density of the light the HSP70 of the Baicalin group increased and which of it the TGF-β〓, increased with the model group; the density of light of the Concha Margatitifera Usta is not different and which of TGF-β〓, increased with the model group; the density of light of the Cholic Acid group is not different and the density of light of it of TGF-β〓 increased with the model group; the density of light of the Hefang Group is not different and which of TGF-β〓 is not different than the model group.

合方治疗脑缺血12小时组缺血脑组织TGF-β1光密度值较缺血12小时模型组无显著性差异（p＞0.05）。本实验结果发现，与单纯缺血12小时、24小时大鼠相比，药物干预组缺血侧大脑皮层TGF-β1免疫反应明显增强，计算机辅助图像半定量分析两组间缺血侧大脑皮层TGF-β1免疫阳性细胞数差异非常显著。说明药物对局灶性脑缺血损伤可能有一定保护作用，其机制可能与诱导脑细胞TGF-β1合成增加有关。然而，药物调控TGF-β1表达，其促TGF-β1表达增强的机制可能是这样的：脑缺血时TGF-β1mRNA表达增加可能与缺氧诱导神经和胶质细胞刺激生长因子表达有关。

Both parameters were closer to those of lowlanders in Tibetan than in Han, which may contribute to less hypoxic pulmonary vasoconstriction in Tibetan.

血浆中ET和NO含量的不同可能是世居高原藏族缺氧性肺动脉收缩反应钝化的原因之一。
