摘 要: | ![]() 目的探讨降钙素基因相关肽(CGRP)和内皮素受体A(ETRA)在蛛网膜下腔出血(SAH)后脑组织中的表达情况及意义。方法日本大耳白家兔45只,随机分为SAH模型组(20只),盐水对照组(15只),穿刺对照组(5只),空白对照组5只。采用枕大池2次注血法制作SAH的动物模型,并进行CGRP和ETRA的免疫组化染色,观察CGRP和ETRA的免疫表达。结果CGRP和ETRA免疫阳性标记在SAH组模型均有表达,CGRP阳性细胞在1h时少量表达,3~7d时表达明显,其中5d时最显著,10d时阳性细胞表达已经减少,但未达到正常水平。SAH模型组ETRA主要表达在神经元和胶质细胞胞浆内,建模后1h时染色较淡;3d时染色最强烈;5d时染色较3d弱,此后染色逐渐变淡。结论SAH后脑组织CGRP和ETRA的表达增强,并呈现明显的动态改变,但两者的变化趋势并不同步;CGRP和ETRA可能在延迟性神经功能障碍的发生与发展中起重要作用。

Abstract: | ![]() Objective To study the expression and the significance of calcitonin gene-related peptide (CGRP) and endothelin receptor A (ETRA) in the brain tissue after subarachnoid hemorrhage (SAH). Methods Forty-five Japanese rabbits were randomly divided into four groups, including SAH-group (n = 20), saline-group (n = 15), puncture-group (n = 5) and blank-group (n = 5). The SAH animal model was established by autologus arterial blood injection into the cisterna magna twice. Immunohistochemical staining for GCRP and ... |
