METHODS : A small intestinal villosity microvessels model and a circulatory simulation system were made .

方法： 根据 小肠 绒毛微血管 结构 设计 制作了 体外模型，建立一套模拟体循环系统。

Simulation study of hemodynamic of small intestinal villosity microvessels in vitro

小肠 绒毛微循环的血流动力学体外研究

Objective To detect the effect of cell apoptosis and regulator gene ( bcl-2 and bax ) in the villosity tissue of dysontogenesis .

目的研究胚胎停止生长患者 绒毛组织中的细胞凋亡及细胞凋亡调控基因bcl-2和bax在凋亡的作用。

DNA content and the aneuploid cell number of malignant mole and choriocarcinoma were markedly higher than those of hydatidiform mole and normal villosity . There were significant differences ( P < 0.01 ) between them .

着 丝 点 结构 变异 与 消失对非整倍体细胞 形成的影响恶性葡萄胎和绒毛膜癌明显高于良性葡萄胎和正常 绒毛，有显著性差异（P<0.01）。
