查询词典 ischemia

The HRV decreasing was correlated tightly with the degree of coronary artery stegnosis and the quantity of coronary artery involved in CAD patients, it indicated that myocardial. ischemia was important cause for HRV decreasing, and CAD severity could be predicted possibly with the Lower HRV.

冠心病患者，心率变异降低不仅与冠脉狭窄严重度有关，而且与冠脉病变的广泛程度有关，提示心肌缺血是冠心病患者HRV降低的重要因素，HRV降低程度对冠心病严重度可能有预测价值。

目的 研究云南产鼠尾草属药物滇丹参、甘西鼠尾、褐毛甘西鼠尾对心肌缺血再灌注损伤的保护作用，并与丹参进行对比。

Wright, Salvia przerwalskii Maxim, Salvia przewalskii Maxim var mandarinorum stib can ameliorate the abnormality of the hemodynamics and have the cardioprotective effects in myocardial ischemia/reperfusion in rat hearts.

滇丹参、甘西鼠尾、褐毛甘西鼠尾能改善急性心肌缺血引起的血流动力学异常；对在体和离体缺血/再灌注引起的心肌损伤具有保护作用。

H. Wright, Salvia przerwalskii Maxim, Salvia przewalskii Maxim var mandarinorum stib have the cardioprotective effects in myocardial ischemia/reperfusion in rat hearts.

滇丹参、甘西鼠尾、褐毛甘西鼠尾对在体和离体缺血／再灌注心肌有保护作用。

HAase may degrade antiangiogenic HA of extracellular matrix, which may stim ulate proliferation of endothelial cells and enhance the curative effect of grow th factors to myocardial ischemia.

HAase可降解细胞外基质中具有抗血管新生作用的HA，促进内皮细胞的增殖，有可能提高促血管生长因子治疗心肌缺血的局部疗效。

It has been demonstrated that STAT3 is activated after cerebral ischemia/reperfusion in cortex and striatum.

以往的研究表明，在脑缺血/再灌注的皮层和纹状体组织中信号转导与转录激活子-3 (STAT3)被激活。

NO is involved in the regulation of DA release from striatum during cerebral ischemia.

NO参与了缺血时纹体DA释放的调节。L-NNA抑制半球缺血时DA的不正常释放可能是其保护缺血大脑的机制之一。

Results Lorcainide at concentration of 0.62mg/L,1.25mg/L and 2.50mg/L had a tendency of decreasing the incidence of arrhythmia during ischemia (P＞0.05),and at 1.25mg/L and 2.50mg/L significantly decreased incidence of arrhythmia during early reperfusion (P＜0.05).Its antiarrhythmic effect was accompanied with elevation of subendocardial threshold,significant abbreviation of action potential duratin in subendocardium and subepicardium,and complete or partly delay of transmural conduction time of pulses.

结果 劳卡胺分别在0.62mg/L、1.25mg/L及2.50mg/L剂量时使缺血性心律失常发生率轻度降低(P＞0.05)，后2种剂量使再灌注早期心律失常发生率明显降低(P＜0.05)；降低心律失常发生率同时可提高心内膜下心室肌兴奋阈，延长心内、外膜下心室肌细胞动作电位时程，延迟或部分延迟冲动跨壁传导时间。

Results Compared with normal group and sham operated control groups, BrdU positive and Nestin positive cells were increased in the hippocampus, dentate subgranular zone and subependymal zone in operated groups after 24 hours of reperfusion of omni-cerebral ischemia.

结果 脑缺血再灌流24 h后，海马、齿状回和室管膜下区的BrdU阳性细胞和Nestin阳性细胞增多，7～10 d达到高峰，术后20 d仍有表达；在室管膜下区，BrdU阳性细胞和Nestin 阳性细胞有向皮质、海马迁移的现象。

Results compared with normal group and sham operated control groups, brdu positive and nestin positive cells were increased in the hippocampus, dentate subgranular zone and subependymal zone in operated groups after 24 hours of reperfusion of omni-cerebral ischemia. the expression of brdu and nestin reached a peak 7-10 days after the operation, and could still be detected 20 days after the operation. the migration of brdu positive and nestin positive cells to the cerebral cortex and hippocampus was observed in subependymal region.

结果 脑缺血再灌流24 h后，海马、齿状回和室管膜下区的brdu阳性细胞和nestin阳性细胞增多，7～10 d达到高峰，术后20 d仍有表达；在室管膜下区，brdu阳性细胞和nestin 阳性细胞有向皮质、海马迁移的现象。

However it can often be frust ating for a child when people are unable to pronounce their name.

但它往往可以令人沮丧的一个孩子当人们无法断言他们的名字。

All these compounds were obtained from this genus for the first time. Compound, 4-cumylphenol, was a new nature product.

所有化合物均为首次从本属海藻中分离得到，其中4cumylphenol为新天然产物。
