查询词典 ischemia

In transient cerebral ischemia and early reperfusion,the reason of blood-brain barrier opening was the addtion of plasma vesicle in brain capillary endothelial cell.

短暂脑缺血及再灌流早期血-脑脊液屏障通透性的改变，主要是由于内皮细胞中胞饮小泡数目增多所致。

Results The average onset age of moyamoya disease was very young. Female was dominant in our studied. Younger patients with moyamoya disease mainly suffered cerebral ischemia (87.5%). Adult patients suffered more cerebral hemorrhage (41.2%). Among clinical manifestations, headache, vertigo, paralysis, hemiplegia or alternative hemiplegia were common symptoms. Sometimes aphasia, dementia, visual acuity were decreasing, epilepsy and chorea minor might occur. 14 cases had received CT examination, but none was diagnosed moyamoya disease by CT. All patients received MRI and MRA examinations were diagnosed as moyatnoya disease.

结果 烟雾病发病平均年龄较轻，女性多于男性；少儿烟雾病患者以缺血改变为主(87.5%)，成年烟雾病患者缺血改变(58.8%)与出血改变(41.2%)相当；临床以头痛、头晕、肢体无力或偏瘫或交替性瘫痪为主要表现，同时可伴失语、智能下降、视力下降、癫痫发作、小舞蹈发作等表现。14例行头CT检查仅示颅内病灶，均未提示烟雾病；25例均行MRI和MRA检查发现颅内病灶，显示颈内动脉虹吸末段和大脑前或中动脉近段狭窄或闭塞，并有脑基底部异常血管网及侧支循环形成，均被诊断为烟雾病。

Serum NO-2/NO-3 and cGMP in 52 cerebral ischemia patients were measured with copper-coated cadmium reduction method and radioimmunoassay.

采用镀铜镉还原法和放射免疫法对52例脑梗死患者血清中NO-2/NO-3和cGMP的含量进行检测。

PART 1 EXPRESSION OF MMP/TIMP IN SKELETAL MUSCLE OF ARTERIAL OCCLUSION DISEASE MODELS OF DOG'S HIND LIMB Objective To study the distribution changes of typeⅠand typeⅢcollagen in skeletal muscle of arterial occlusion disease models of dog's hind limb and the expression of MMP-2/TIMP-2 in skeletal muscle of arterial occlusion disease models of dog's hind limb. To investigate the significances of collagen metabolism and MMPs in skeletal muscle remodeling due to ischemia.

第一部分MMP/TIMP在犬后肢动脉闭塞性病变模型骨骼肌中表达的变化目的研究Ⅰ型胶原、Ⅲ型胶原在犬后肢动脉闭塞性病变模型骨骼肌的分布变化以及MMP-2、TIMP-2在犬后肢动脉闭塞性病变模型骨骼肌表达的变化，探讨胶原代谢和基质金属酶系统在缺血导致的骨骼肌重塑中的意义和作用。

In our study, RIPC was achieved by temperarily tightening the right hindlimb with an elastic rubber tourniquet to cause ischemia.

我们将大白鼠（250±30g）施以300－350 mmHg的后肢缺血压力，并且依据后肢缺血时间的不同分成四个组别，在最后一次后肢缺血循环结束24小时后，进行可逆的缺血性中风90分钟。

Repetitive nocturnal hypoxemia and arousals lead to ischemia reperfusion, cellular degeneration, and apoptosis, cardiac remodeling; and provide fertile environment for reentrant arrhythmias.

反复的夜间低氧血症和觉醒导致局部缺血再灌注，细胞变性和凋亡，心肌重塑，并为折返型心律失常的发生提供环境。

Methods: The cerebral cortical astrocytes and neurons of rats were cultured and the model of simulated cerebral ischemia and reperfusion was set up in vitro. The activity, survival rate, death rate of the neurons, leakage rate of lactate dehydrogenase and the activity of nitric oxide synthase of cerebral cortical neurons were measured after 18 boors of reperfusion.

分离纯化培养大鼠大脑皮质Ast和神经元，体外模拟脑缺血再灌注损伤模型，用ACM培养损伤后的神经元，测定其神经元的活性、存活率、死亡率、培养液乳酸脱氢酶的漏出率和NOS强阳性细胞的表达量。
