查询词典 hypoxia

Objective To observe the changes of the concentration of Ca2+, contents of cAMP, CaM and activity of Ca2+/CaM-PK II in pheochromocytoma PC12 cells after combined soman and hypoxia injury.

目的 观察缺氧复合梭曼中毒后大鼠肾上腺嗜铬细胞瘤PC12细胞内游离钙的浓度(［Ca2+］)、cAMP、钙调蛋白和钙调蛋白激酶Ⅱ（Ca2+/CaM-PK Ⅱ）的变化。

Results The changes of ［Ca2+］, the contents of CaM, cAMP were significantly higher in hypoxic and soman intoxicated group than in soman intoxicated group and control group under hypoxia; but the activity of Ca2+/CaM-PK Ⅱ were significantly decreased.

结果 缺氧中毒组PC12细胞cAMP、CaM含量在中毒后24 h明显高于单纯中毒组、缺氧对照组和正常对照组；缺氧中毒组PC12细胞Ca2+/CaM-PK Ⅱ活性在中毒后24 h明显低于单纯中毒组、缺氧对照组和正常对照组。

Soman intoxication ; hypoxia ; nerve cell ; calcium

梭曼中毒；缺氧；神经细胞；钙

Pulmonary vascular α〓 andβ〓 gene expression levels responsed to hypoxia and salbutamol using in situ hybridization.

原位核酸分子杂交检测缺氧及salbutamol对大鼠肺血管α〓B及β〓基因表达的影响，3。

After analyzing the Sp1 DNA sequence within 5'-UTR and promoter region, we found one typical IRES-conserved sequence localizing within 5'-UTR of Sp1 genomic sequence. The reporter assay and polysome distribution assay revealed that Sp1 could be accumulated strongly and rapidly under hypoxia/ischemia neuron cells.

在Polysome distribution assay的结果显示，Sp1在缺糖缺氧之后转译效率有提高的情形，接著分析Sp1 5'-UTR，发现可能存在一个典型的IRES结构，利用bicistronic assay也证实了Sp1的堆积是透过IRES所导致。

Results: the co pretreatment group received pre-exposure to 250 ppm of co significantly reduced the expression of chop in the heart compared with i-r group; however, hypoxia pretreatment group showed no such effect.

结果：给予250 ppm的co前处理组家兔的心肌chop表达明显低于i-r组；而低氧前处理组没有此作用。

BackgroundIschemic preconditioning refers to the increased tissue resistance to ischemia reperfusion injury that can be induced by the pre-exposure to one or more brief periods of hypoxia followed by reoxygenation.

背景： 缺血预处理是短期缺血应激使机体组织对随后更长时间缺血再灌注损伤产生明显保护作用的一种适应性机制，缺血预处理的保护作用具有呈初始阶段、延迟阶段双峰表现的特点。

Results: The CO pretreatment group received pre-exposure to 250 ppm of CO significantly reduced the expression of CHOP in the heart compared with I-R group; however, hypoxia pretreatment group showed no such effect.

吸入低浓度的CO（250 ppm）能明显改善心肌缺血-再灌注损伤；其机制可能为外源性CO缓解缺血-再灌注激发的过度内质网应激，抑制CHOP过表达，减轻ERS相关细胞凋亡的发生，从而减轻心肌缺血-再灌注损伤。

The early intervention on haematoma surround tissue by early input oxygenised liquid during hypertensive cerebral haemorrhage surgery that could effectively relieve cerebral oedema and improve cerebral ischemic hypoxia to save reversibly injured neurons surrounding haematoma,is an effective intervention, which is helpful to the cerebral protection in the patients with hypertensive cerebral haemorrhage.

在高血压脑出血术中早期输入携氧液对血肿脑周围组织提供早期干预，有效减轻脑水肿，改善脑组织缺血缺氧，挽救血肿周围可逆性损伤的神经元是一项有效的措施，有利于高血压脑出血患者的脑保护。

Objective To study the changes of N-methyl-D-aspartate-receptor-channels current in developing hippocampal neurones during hypoxia and effect of adenosine intervention.

目的 研究缺氧对发育中的海马神经元N-甲基－D门冬氨酸受体通道电流的影响及腺苷干预作用的离子通道机制。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
