摘要:
In producing a titanium strip using a continuous hot strip mill, the invention discloses a method of producing a titanium hot coil by a continuous hot rolling system characterized by the steps of heating a titanium slab to 700.degree.-950.degree. C. inside a heating furnace, then performing the hot rolling, and winding the hot rolled strip in a coil form while the strip is kept at a temperature of not lower than 450.degree. C. under a condition that at the time of taking up the leading portion of the resulting titanium hot rolled strip after hot rolling, its trailing portion is being caught by the final stand roll of a finishing mill of the continuous hot strip mill.

A novel process for preparing tumor-specific T cells is disclosed. According to the invention, antitumor-active, tumor-specific T cells are prepared by transducing a TCR gene from a tumor-specific CTL into antitumor-active T cells that have been nonspecifically activated, thus enabling tumor-specific cellular immunotherapy to be carried out from even small amounts of blood. MHC class I-restricted, tumor-specific Th cells are obtained by the method, allowing for the production of cells that react with tumor cells expressing an MHC class I molecule and show a helper activity and an antitumor activity.

An objective of the present invention is to provide novel therapeutic agents for cancer, which have an excellent antitumor effect in cancer patients by enhancing their immune function. The present inventors discovered that the administration of at IL-6 inhibitor and/or gemcitabine or a salt thereof to tumor-bearing organisms yields an excellent antitumor T cell response-enhancing effect, and completed the present invention. In addition, the present inventors discovered that the T cell response-enhancing effect produces an excellent antitumor effect.

Safe handling spraying device, which comprises a reservoir where is assembled an actuating lever or, manually or automatically actuating air pumps, that perform the internal reservoir pressurization. Inside of it, there is a pressure chamber where is stored water and the Chemical Concentrated product that is inside a pliable tightly closed bag. The reservoir (10) is designed for supplying water (Ag), the chemical concentrated product (CCP) is stored separately in a pliable container (12). The pliable container (12) is disposed inside of a pressure chamber or water reservoir (10), so that the same pressure defined inside the reservoir (10) is applied to the pliable container (12) simultaneously. The output end of the pliable container (12) is connected to the inlet of a mixing device (20) which doses the CCP continuously. After the CCP had been mixed with water, it communicates with a hose provided with an actuating trigger (30) and spraying nozzle (27) at the free end.

A fuel cell includes a solid polymer electrolyte membrane and cathode and anode catalyst layers held between a fuel electrode substrate having a surface area larger than that of the cathode catalyst layer and an oxidizer electrode substrate having a surface area larger than that of the anode catalyst layer. The fuel electrode substrate includes a fuel-sealing support portion surrounding the cathode catalyst layer. The oxidizer electrode substrate includes an oxidizer-sealing support portion surrounding the anode catalyst layer. The fuel-sealing and oxidizer-sealing support portions each include pores partially or wholly filled with a resin. The fuel-sealing support portion is bonded to the membrane by the resin at a position closer to an outer edge of the membrane than is the cathode catalyst. The oxidizer-sealing support portion is bonded to the membrane by the resin at a position closer to the outer edge of the membrane than is the anode catalyst.
