摘要 阿片肽及其受体系统在缺血性脑卒中的病理生理发展过程中具有非常重要的作用。一方面脑缺血导致内源性阿片肽的含量升高,而阿片受体的表达量明显下降;另一方面阿片类物质可能通过调节脑血管收缩、保护脑神经元损伤及影响机体免疫内分泌系统等几方面来影响缺血性脑卒中的发展。因此调节阿片系统活性的药物有可能成为脑卒中防治研究的新方向。 Opioid peptides and their receptors play an important r ole in the pathophysiologic process of stroke. The concentration of endogenous o pioid peptides elevates, while the density of opioid receptors decreases in CNS during cerebral ischemia; on the other hand, opioids influence the development o f stroke through regulating the contraction of cerebral vessel, immuno-endocrin e system and neuroprotection against injury. Thus, drugs that regulate the opioi d system may be a new therapeutic approach for prevention and treatment of cereb ral ischemia.
