中文摘要：
利用存在缺陷的LB膜来模拟受损伤的肾上皮细胞膜诱导肾结石矿物草酸钙（caoxa）晶体生长．经2．5mmol·L^-1。的草酸钾溶液对二棕榈酰磷脂酰胆碱（DPPC）的LB膜进行处理后，可强化LB膜中液态扩张相（LE）和液态凝聚相（LC）之间的结构差异，原子力显微镜（AFM）证实了圈状缺陷的存在．以LB膜的圈状缺陷为模板，诱导了一水草酸钙（COM）晶体环状图案．相比之下，未经草酸钾处理的LB膜只诱导生成零散的六边形COM晶体．
英文摘要：
Defective LB film was used as model for injured renal epithelial membrane to induce the growth of calcium oxalate monohydrate （COM） crystals, which was the major inorganic component found in renal calculi. After the LB film of dipalmitoylphosphatidylcholine （DPPC） was treated by 2.5 mmol·L^-1 potassium oxalate, the structural differentiation between liquid expanded （LE） phase and liquid condensed （LC） phase in LB film was strengthened and circular defects appeared. These circular defects were proved by atomic force microscopy （AFM）. Such circular defects could induce ring-shaped patterns of COM crystals. In comparison, the LB films without pretreatment by potassium oxalate only induced randomly growth of COM crystals.
