腹膜透析中物质跨腹膜转运的数学模型

Trans-membrane Transport Kinetic Models in Peritoneal Dialysis

腹膜是生物半透膜。我们综述了腹膜透析过程中溶质和水跨腹膜转运的几种数学模型,包括膜模型、三孔模型、扩展三孔模型、分布模型。它们分别从不同方面揭示了腹膜的物质转运机理。重点介绍了三孔模型。

The peritoneum is a biologic semi-permeable membrane. This article presents some kinetic models of fluid and solute trans-peritoneal transport in peritoneal dialysis including the membrane model, the three-pore model, the extended three-pore model and the distributed model. In these models different trans-peritoneal transport mechanisms were revealed. The three-pore model is emphasized.
