查询词典 ischemia

Methods Chronic forebrain ischemia model was made by permanent occlusion of bilateral carotid arteries. The cognitive function of the rats were estimated by Morris water maze test and rCBF in prefrontal cortex, parietal cortex, hippocampus and subcortex was assessed by laser doppler flowmetry on any different timepoint after operation (24 h, 7, 14 d, 1, 2, 3, 4 mon).

Aim: To investigate time of sublethal cerebral ischemia and time of protective effects of CA1 neurons.

目的：探讨预缺血时间及间隔时间窗对CA1区锥体细胞的影响。

The expression of heat shock protein 70 was significantly greater at the ends of sublethal ischemia/reperfusion in UP rats than in control rats.

大鼠静脉给予10mg/kg的U50，488H，当24小时后心脏在遭受缺血/再灌注损伤后，其心肌细胞内HSP70的表达较对照组明显增加。

This phenomenon was called cerebral ischemic tolerance, and the sublethal brain ischemia given in advance was called cerebral ischemic preconditioning.

远端缺血预处理是指预先对靶器官以外的组织或器官进行缺血预处理，使靶器官产生缺血耐受的现象。

Recently, with profound studies of ischemic preconditioning, protective effect of remote organ preconditioning which was a brief episode of sublethal ischemia in an organ remote from the target organ, was found.

近来，随着缺血预处理研究的深入，发现了远隔器官缺血预处理现象，为采用非生命器官的短暂亚致死性缺血预处理对抗心脑等生命器官的缺血/再灌注损伤提供了线索。

Sublethal ischemic preconditioning induced chaperone hsp70 expression in the CA1 neurons after 24 h reperfusion following 10-min ischemia.

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
