Abstract: The present invention is a peritoneal dialysis and hemodialysis hybrid-remedy planning method using an index that is shared by both peritoneal dialysis and hemodialysis and indicates an effect of dialysis. To be specific, the index is M/C(0)/VB, which is obtained by dividing a ratio M/C(0)—where M is a removal amount of a solute for a fixed time period, and C(0) is a concentration of the solute in blood before the dialysis—by a patient's body fluid volume, VB. The present invention is capable of representing the dialysis effect of PD and HD as an integrated sum, and achieving concise and explicit PD and HD hybrid-remedy planning.

Abstract: The present invention provides a method for controlling the proliferation and differentiation of cord blood-derived hematopoietic stem cells with excellent safety when proliferating them by culturing. The hematopoietic stem cells are inoculated into a medium containing a sonicated liquid component of cord blood. The proliferation and differentiation of the cord blood hematopoietic stem cells can be inhibited in the presence of the sonicated liquid component of cord blood. On the contrary, the proliferation of cord blood hematopoietic stem cells can be accelerated by inoculating the hematopoietic stem cells into a medium containing a non-sonicated liquid component of cord blood. Thus, according to the present invention, by using serum derived from cord blood, it is possible to regulate the inhibition of the proliferation and differentiation of cord blood hematopoietic stem cells and the acceleration of the proliferation of the same as desired.
