摘　　要：体外模拟胆结石实验中,研究了腺嘌呤对金属离子-脱氧胆酸凝胶模拟体系的有序结构生成时间、生长速度和有序形貌及微观结构的影响。用扫描仪、体视显微镜和电子扫描显微镜观测有序结构的形貌;红外光谱分析表征有序沉淀物的微观结构。实验结果表明:腺嘌呤改变体系有序结构的时空图案及沉淀组成,有显著影响;红外谱图分析显示腺嘌呤参与体系中金属离子的配位。通过考察人体中重要的生命物质对结石影响的研究,学生兴趣浓,实验内容阶段性、可操作性强,与本科生的专业基础联系密切,应用于本科生的研究型开放实验教学系统,有利于培养学生的创新能力。A vitro experiment is designed to simulate gallstone generation in order to study the effect on the time of the orderly structure, growth rate and the orderly morphology and microstructure structure of adenine to metal ion-deoxycholic gel system. Scanner, stereomicroscope and electron scanning microscope are used to record the morphology of ordered structure, FTIR is used to analyze and characterize the microstructure of ordered precipitates. After a series of experiments, results showed that adenine participates in the coordination of sediment of any simulation systems and affects the ordered structure of any simulation systems. By the investigation of gallstone generation affected by adenine, students show their interests in learning. The experiment content has the features of stage and operation, has a close connection with student specialty, and is helpful to cultivate innovation ability of students.
