1.
The gene expression levels of amyloid precursor protein(APP) and presenilin 1(PS1) in the peripheral blood samples of patients with Alzheimer s disease(AD) and their association with the disease were studied.
为了检测Alzheimer病(Alzheimer’s disease,AD)患者外周血中淀粉样前体蛋白(Amyloid Precursor Protein,APP)基因及早老素1(Presenilin 1,PS1)基因的表达情况,进而探讨APP及PS1基因的表达与AD的相关性,采用SYBRGreenⅠ的方法对45例AD患者、25例血管性痴呆(vascular dementia,VD)患者及60名正常对照组样本的mRNA进行绝对定量,检测得到APP基因及PS1基因在对照组中的表达水平分别为0。

补充资料：水平列管蒸发器
分子式：
CAS号：
性质：早期使用的一种简单的自然循环蒸发器。加热管为φ20～40mm的无缝钢管或铜管，管内通加热蒸汽，由加热管构成的水平管束浸没于溶液中。溶液在列管外沸腾蒸发并作自然对流。
