缺血再灌注脑组织病理形态及脂质过氧化的动态观察

目的:探讨缺血再灌注脑组织病理形态及丙二醛含量变化的关系.方法:阻断双侧颈总动脉和椎动脉结合低血压法复制兔脑完全性缺血再灌注模型,观察心脉龙对脑组织病理形态变化及脂质过氧化的影响.结果:心脉龙能抑制膜脂质过氧化作用,且缺血再灌注脑组织丙二醛含量变化与其病理形态改变具有一致性.结论:动态观察血液丙二醛,可作为评价脑缺血性疾病治疗和预后的检测指标.

Responses of CDKs and p53 in Delayed Ischemic Neuronal Death

Stroke is a debilitating disease that affects millions each year.While in many cases cerebral ischemic in jury can be limited by effectivw resuscitation or thrombolytic treatment,the injured neurons wither in a process known as delayed neuronal death(DND).Mounting evidence indicates that DND is not simply necrosis played out in slow motion but apoptosis is triggered.Of particular interest are two groups of signal proteins that participate in apoptosis-cyclin dependent kinases(CDKs) and p53-among a myriad of signaling events after an ischemic insult.Recent investigations have shown that CDKs,a family of enzymes initially known for their role in cell cycle regulation,are activated in injured neurons in DND.As for p53,new reports suggest that its up-regulation may represent a failed attempt to rescue in jured neurons,although its up-regulation was previously considered an indication of apoptosis.These observations thus rekindle an old quest to identify new neuroprotective targets to minimize the stroke damage.In this review,the author will examine the evidence that indicates the participation of CDKs and p53 in DND and then introduce pre-clinical data to explore CDK inhibition as a potential neuroprotective target.Finally,using CDK inhibition as an example,this paper will discuss the pertinent criteria for a viable neuroprotective strategy for ischemic in jury.
