- W1488254967 abstract "目的观察P物质(SP)对人脐静脉张力的调节及其对体外培养人脐静脉内皮细胞(HUVEC)膜上Ca2+通道及胞浆内游离Ca2+浓度[(Ca2+)i]的调控作用.方法应用常规生理记录仪,记录SP对人脐静脉张力的影响,用共聚焦激光扫描显微术和膜片钳单通道记录技术对体外培养HUVEC胞浆内(Ca2+)i、膜上Ca2+通道开放情况进行观察.结果SP具有内皮依赖性舒张人脐静脉的作用,促使体外培养HUVEC胞膜上Ca2+通道开放和胞浆内(Ca2+)i明显升高.结论SP对人脐静脉张力的舒张作用可能通过HUVEC胞浆内储存的(Ca2+)i释放和膜上Ca2+通道开放,达到其调节效应." @default.
