The defective Langmuir-Blodgett film of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine induced by potassium oxalate(K2C2O4) and its effect on nucleation and growth of calcium oxalate monohydrate were investigated with the aid of atomic force microscopy and scanning electron microscopy.

采用扫描电子显微镜和原子力显微镜研究了经不同浓度草酸钾(K2C2O4)处理后二棕榈酰磷酯酰胆碱的缺陷LB膜及其对一水草酸钙成核和生长的影响。

We also use rank sum test to analyse the differe- nce between the light pre-eclampsia group and the severe pre-eclampsia group (P=0.000),the early onset pre-eclampsia group and the late onset pre-eclampsia group (P=0.003). All of the results give the same conclude that the differences within the three groups are significant (P.05). Conclusion: We conclude that HLA-G proteins are normally expressed in invasive trophoblasts and HLA-G proteins expression is defective in most pre-eclamptic placenta.We propose that trophoblasts lacking HLA-G proteins are vulnerable to attack by the maternal immune system.

结论HLA-G分子特异性分布于胎盘EVCT的胞膜及胞浆中，生理妊娠组、子痫前期组间差异性存在表明其表达量的下降与子痫前期的发病相关；轻、重度子痫前期组间显著差异表明HLA-G分子表达量的下降与子痫前期病情严重程度相关，早发型重度子痫前期患者胎盘组织中HLA-G分子的表达明显低于迟发型组，提示我们HLA-G分子表达的降低程度还与发病早晚有关。
