Patent number: 8460930Abstract: 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.Type: GrantFiled: January 22, 2010Date of Patent: June 11, 2013Assignee: JMS Co., Ltd.Inventors: Satoshi Hirai, Kasumi Ogata

Patent number: 8449496Abstract: The present invention is a peritoneal function testing method characterized by using a ratio MTACun/MTACc calculated using MTACun and MTACc as an index for a peritoneal function test, where MTACun is an overall mass transfer-area coefficient for urea nitrogen and MTACc is an overall mass transfer-area coefficient for creatinine. The use of MTACun/c of the present invention in this way enables examination of the future peritoneal function of a patient (a mechanism of deterioration in peritoneal function). To be specific, MTACun and MTACc can be obtained by computing Pyle-Popovich model. In addition, the peritoneal function testing method may further calculate a permeability coefficient for cell pores (LPSC) and an overall permeability coefficient (LPS) from Three-Pore Theory model while obtaining a ratio LPSC/LPS calculated using the LPSC and the LPS, and may use the LPSC/LPS ratio and the MTACun/MTACc ratio as indexes for the peritoneal function test.Type: GrantFiled: May 21, 2009Date of Patent: May 28, 2013Assignee: JMS Co., Ltd.Inventors: Hiroyuki Hamada, Masahiro Okamoto

Patent number: 8414515Abstract: A conduit tube (90) that communicates with an intracardiac blood inflow port (50) and a liquid medicine injection port (72) and allows blood from the intracardiac blood inflow port and a liquid medicine from the liquid medicine injection port to flow into a cardiotomy section (2) is inserted from above downward in the cardiotomy section 2. A blood flow channel (93) for the flow of blood and a liquid medicine flow channel (95) for the flow of a liquid medicine are formed independently of each other in the conduit tube. With respect to the vertical direction, the lower end of a blood conduit tube portion (94) that forms the blood flow channel is located at a lower position than the lower end of a liquid medicine conduit tube portion (96) that forms the liquid medicine flow channel. This prevents the generation of negative pressure in the liquid medicine flow channel due to the flow of blood. It also reduces the resistance to the inflow of a liquid medicine into the cardiotomy section.Type: GrantFiled: August 21, 2008Date of Patent: April 9, 2013Assignee: JMS Co., Ltd.Inventors: Yutaka Katsuno, Minoru Tanaka
