The dissolution rates of cholesterol in model bile salt solutions are controlled by diffusion in slowly flowing bile and by interfacial kinetics in rapidly flowing bile. At low flow, dissolution varies with the square root of bile flow and can be predicted, a priori, from existing correlations of mass transfer. At high bile flow, dissolution is independent of bile flow and is probably dominated by the rate of micelle adsorption. These results show that cholesterol gallstone dissolution, a potential nonsurgical therapy for cholelithiasis, can be accelerated little in slow bile, but more significantly in rapidly flowing bile.
胆固醇在模拟胆盐溶液中的溶解速率,在缓慢流动的胆汁中受扩散控制,在快速流动的胆汁中受界面动力学控制。在低流速时,溶解速率随胆汁流速的平方根变化,并且可以根据现有的传质相关性事先预测。在高胆汁流速时,溶解与胆汁流速无关,可能受胶束吸附速率主导。这些结果表明,胆固醇胆结石溶解作为一种潜在的胆结石非手术治疗方法,在缓慢流动的胆汁中加速效果甚微,但在快速流动的胆汁中加速效果更显著。
