五、试验分四组：(1) Control组假手术组，Wister大鼠麻醉后，开腹后，即将伤口缝合，6h后切取左肾；(2) ECs组供肾经ECs(不含脂质体/ODN复合物)低温缺氧保存6h，移植到受体大鼠6h后切取移植肾；(3)deeoy onN组供肾经含1 pM的deeoy onN脂质体复合物的ECs 低温缺氧保存6h，移植到受体大鼠6h切取移植肾；(4)sc~。

The descending rates were 19.4% and 21.4%, respectively, which showed significant differences (P.01). While in the photopic environment, the average dynamic visual acuities under the conditon of acute mild hypoxia didn't show significant differences, compared with those under the normal condition.

结果：在暮视光环境条件中，2种（30、45 km/h）纵向动态视力的平均值急性轻度缺氧状态下比正常状态下有明显下降（P.01），下降率分别为19.4%和21.4%；在明视光环境条件中，纵向动态视力的平均值急性轻度缺氧状态下与正常状态下相比无显著变化。

The Na+ and K+ currents of hippocampal neurons before and after hypoxia-reoxygenation with xionggui diwan pretreatment: Before hypoxia-reoxygenation, the ampli tudes of Ⅰ Na and J K of hippocampal neurons at the threshold point were very similar, without significant difference.

芎归滴丸预处理后缺氧-复氧前后海马神经元的Na+、K+变化：缺氧-复氧前海马神经元Ⅰ Na Ⅰk在阈值处的幅度很接近，差异无显著性意义。

Changes in brain tissue similar to those of newborn in HIE were detected after 2 hours of hypoxia and ischemia.Meanwhile,swelling of kidneys,hemorrhage below encapsules,swellin of tubular epithelial cells,necrosing and falling of a few tubular epithelial cells,and narrowing of tubular lumens were observed.The basement membranes of renal tubules remained normal ...

结果发现新生猪经2小时缺氧缺血后，在脑组织出现类似新生儿HIE病理损害的同时，肾脏出现肿胀，包膜下出血，肾小管上皮细胞肿胀，管腔变窄，少数上皮细胞坏死脱落，肾小管基膜完整，血清尿素氮及肌酐明显升高（P＜0.025及P＜0.05），表明在HIE状态下新生猪已出现肾脏的病理及功能损害，但损害程度较轻，解除缺氧72小时后，上述损害基本恢复正常。

When A〓-A〓-O-A〓 system, using fixed beds as anaerobic and anoxic reators and draft-tube fluidised bed as aerobic reactor (total hydraulic residence time 26. 2h, 9, 5, 7. 2 and 5h for each stage, and recycle ratio of mixed liquor from oxic reactor to the first anoxic reactor 5: 1), is used, the removal rates of COD, NH〓N and TN reach 97, 95. 5 and 90% respectively (influent COD, NH〓-N and TN 1204. 8, 274. 3 and 443mg/l respectvely).

采用A〓-A〓-O-A〓流程和简捷硝化-反硝化过程，以固定床作厌氧反应器和缺氧反应器，以内循环式生物反应器作好氧反应器，系统总水力停留时间为26.2h，各段停留时间分别为9h，5h，7.2h和5h，好氧反应器和第一级缺氧反应器之间的混合液回流比为5：1，系统进水COD为1204.8mg/l，NH〓-N为274.3mg/l，TN为443mg/l时，COD、NH〓-N和TN的去除率分别可达97%、95.5%和90%。

This article introduces the effect of high central nervous system,changes of cerebral blood flow after hypoxia,damage of hypoxia to neurons in the respiratory center,neurotransmitters and neuromodulators in hypoxic respiratory depression.

Barnard等[2]在成年动物也发现了类似的情况，并且指出，缺氧2h内，颈动脉窦传入神经放电一直加强。以上研究结果提示，不论在新生动物还是成年动物，缺氧性呼吸抑制的发生都有其中枢来源。

The degree interrelates partly with the structure of sleep, and totally with SaO2 and total arousal index.
