The invention ligatures the single ureter into mouse kidney fiber mode, watches the stomach treatment function on DS. Wherein, the 3D mouse is randomly divided into four groups as false surgery group, mode group, DS group and anode contrast chlorine group; after 7 days after feeding drug, killing the mouse, taking out the kidney, slicing with paraffin, colorizing with HE, watching in light lens; the experiment proves that the DS group and anode contrast group have similar kidney state and mode; but the DS group and anode contrast chlorine group have reduced expansion degree of nephric tubule epithelial cell, to reduce the foam generation, and the ill parts are distributed in sheets, whose range is less than 25% and different significance is lower than 0.05; using 293 cell to detect the effect of DS on the fiber cell increment, while the result proves that when DS density is 500mg/ml, it can restrain the 293 cell increment caused by vessel contract element II, similarly as the restrain function of DS on the mouse kidney filter process.
