Stool fluid has been obtained for analysis by homogenization and high speed centrifugation of fresh stool. This fluid, from two healthy individuals with soft stools has been compared with stool dialysate obtained in vivo by retrieval of swallowed dialysis bags from their stools. Stool fluid was more acid, with a higher osmolality, an increased concentration of organic anions, sugar and ammonia, and a lower bicarbonate concentration than dialysate in vivo. It is suggested that in the individuals studied, dialysate in vivo may not be in equilibrium with the stool fluid surrounding it, and may not represent a true dialysate of faecal water.
通过对新鲜粪便进行匀浆和高速离心获取粪便液用于分析。已将来自两名粪便柔软的健康个体的这种液体，与通过从其粪便中取回吞咽的透析袋在体内获得的粪便透析液进行了比较。与体内透析液相比，粪便液酸性更强，渗透压更高，有机阴离子、糖和氨的浓度增加，碳酸氢盐浓度更低。研究表明，在所研究的个体中，体内透析液可能与其周围的粪便液未达到平衡，可能并不代表粪便水的真正透析液。
