According to the 22nd edition of "The American Illustrated Medical Dictionary",dialysis[dia=through,apart,across or between;lysis=to loose]is defined as the process of separating crystalloids and colloids in solution by the differences in their rates of diffusion through a semipermeable membrane:crystalloids pass through readily,colloids very slowly or not at all(1).……展开更多
