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.
