高血压循环内皮祖细胞变化和动脉弹性的关系

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2012
【目的】本研究旨在探讨高血压患者循环内皮祖细胞(EPC)数量和功能变化与动脉弹性的关系。【方法】检测20例高血压患者和21例年龄匹配血压正常者的大动脉弹性(C1)和小动脉弹性(C2)。同时用流式细胞仪测定测定CD34和KDR双标阳性循环内皮祖细胞水平,ac-LDL及lectin荧光标记方法评估体外培养内皮祖细数量,检测内皮祖细胞的迁移和增殖能力。【结果】与血压正常者相比,高血压患者C1和C2减退,循环内皮祖细胞迁移和增殖功能明显下降,但是两组患者内皮祖细数量无明显差别 ...

聚合物外套避雷器密封试验的革新

open access: yesDianci bileiqi, 1995
聚合物外套避雷器密封试验的革新传统的瓷质外套避雷器的密封试验方法不适用于聚合物外套避雷器,因为它内部没有气体空间。提出的新方法是把试品先进行热水循环,促进其老化和进水,然后测定其界面泄漏电流以预测其密封性。建议工厂也对此方法进行验证。[摘自Trans...
