摘要 目的:通过检测肠壁组织中酪氨酸激酶受体C-kit蛋白(C-kit)的表达及分布,观察Cajal间质细胞在腹泻型肠易激综合征模型大鼠小肠、回盲部及结肠中的变化,并初步探讨其变化在肠易激综合征中的意义。方法:通过对新生大鼠结直肠扩张(colorectal distension,CRD)制备肠易激综合征模型,40d后观察大便性状;通过腹壁回撤反应(abdominal withdrawal reflex,AWR)评分评估内脏敏感性;小肠、回盲部及结肠组织常规HE染色,光镜下观察病理学变化;免疫组化检测肠壁组织中C-kit的表达及分布。结果:实验组大鼠大便Bristol评分明显升高;在相同压力的直肠刺激下AWR评分明显高于对照组;小肠、回盲部及结肠组织的C-kit表达显著增强。结论:新生大鼠结直肠扩张可以制备肠道分泌、运动和内脏敏感性均增强的肠易激综合征模型;Cajal间质细胞可能在腹泻型肠易激综合征发病中有重要的意义。
