Patent number: 7745613Abstract: Carbonyl compounds generated and accumulated in the peritoneal dialysate can be inactivated or eliminated by a carbonyl compound-trapping agent such as aminoguanidine. Carbonyl compounds generated during sterilization and storage of the peritoneal dialysate can be eliminated by pre-contacting with the trapping agent. Further, it is possible to eliminate carbonyl compounds transferred from the blood to the peritoneal cavity of the patient during peritoneal dialysis treatment, by adding the trapping agent to the peritoneal dialysate or by circulating the fluid through a carbonyl compound-trapping cartridge. Intraperitoneal protein modification by carbonyl compounds is inhibited by the present invention, thereby sufficiently reducing peritoneal disorders associated with peritoneal dialysis treatment.Type: GrantFiled: September 22, 2006Date of Patent: June 29, 2010Assignees: Tokai University Educational SystemInventor: Toshio Miyata

Patent number: 7736472Abstract: A pressure source material is loaded into a space having constraint device 1, which is formed partly by optically transparent material 1a, 1b, and is disrupted under volume constraint. Light energy is externally supplied to the pressure source material constrained in the space through the optically transparent material by employing the device to apply light energy. The disruption of atomic bonds in the pressure source material is induced by heating the pressure source material above the boiling point thereof through the supplied energy. Exceptionally high pressures are generated in the space by the use of expansive forces arising from the disruption of atomic bonds. Such a configuration can implement ultrahigh pressure abilities that has not been achieved, so far.Type: GrantFiled: January 2, 2008Date of Patent: June 15, 2010Assignee: Tokai University Educational SystemInventor: Yasushi Kawashima
