目的 通过对单结合胆红素(monoconjugated bilirubin,MCB)水溶液超微形态及早期动态变化进行观察并与非结合胆红素(unconjugated bilirubin,UCB)对照,探讨MCB与胆石形成的关系;为MCB和UCB在胆汁中的超微形态提供参考依据.方法 用透射电镜对MCB与UCB的相对生理水溶液进行了动态观察.结果 发现MCB的动态变化可分为4个阶段:(1)出现微小颗粒组成的圆形聚集物;(2)微小颗粒消失,融合成等大的融合物;(3)融合物进一步聚集成较大融合物;(4)较大融合物周边出现溶化现象,同时析出小规则类似UCB超微形态物.UCB的动态变化可分为3个阶段:(1)出现大小不等块状物;(2)块状物有聚集趋势,没有熔化与融合现象;(3)聚集物进一步聚集增大.结论 MCB的水溶解度较小,容易从胆汁析出并聚集,其理化性质不稳定,早期形态变化活跃,可能在胆石形成的始动期起重要作用;UCB理化性质稳定,在胆汁中也容易聚集、沉淀形成胆石.
目的 通過對單結閤膽紅素(monoconjugated bilirubin,MCB)水溶液超微形態及早期動態變化進行觀察併與非結閤膽紅素(unconjugated bilirubin,UCB)對照,探討MCB與膽石形成的關繫;為MCB和UCB在膽汁中的超微形態提供參攷依據.方法 用透射電鏡對MCB與UCB的相對生理水溶液進行瞭動態觀察.結果 髮現MCB的動態變化可分為4箇階段:(1)齣現微小顆粒組成的圓形聚集物;(2)微小顆粒消失,融閤成等大的融閤物;(3)融閤物進一步聚集成較大融閤物;(4)較大融閤物週邊齣現溶化現象,同時析齣小規則類似UCB超微形態物.UCB的動態變化可分為3箇階段:(1)齣現大小不等塊狀物;(2)塊狀物有聚集趨勢,沒有鎔化與融閤現象;(3)聚集物進一步聚集增大.結論 MCB的水溶解度較小,容易從膽汁析齣併聚集,其理化性質不穩定,早期形態變化活躍,可能在膽石形成的始動期起重要作用;UCB理化性質穩定,在膽汁中也容易聚集、沉澱形成膽石.

Objective To study the correlation between MCB(Monoconjugated bilirubin) and the formation of the gallstone and provide some useful information on the morphology and ultrastructure change of MCB and UCB(Unconjugated bilirubin) in bile.Methods The morphology and ultrastructure change of MCB and UCB in water solution were observed dynamically by transmition electron microscope at early stage of stone formation.Results The change of MCB can be divided into 4 stages:1) circular aggregations of particles appeared;2) The particles incorporated and formed same size small masses;3) The small masses incorporated and formed big masses;4) The edges of some big masses were dissolved;some masses similar to UCB were separated out.The morphology and uhrastructure change of UCB can be divided into 3 stages in water solution: 1) some square masses appeared in different size;2) the masses had a tendency to aggregate together,but not dissolved and incorporated;3) the aggregations of masses became lager.Conclusion The MCB has little solubility in water solution and easily separate out and aggregate in bile.MCB is unstable and actively change in early conformation and may play an initial role in stone formation.The UCB is stable and also easily aggregate precipitate in bile,which contribute to the formation of stone.
