Abstract: The present invention provides a composition for treating or preventing renal cell cancer, the composition comprising, as an active ingredient, D-allose and/or a derivative thereof and/or a mixture thereof, and being characterized by being administered through the intestinal tract (for example, oral administration). Moreover, the present invention provides a method for treating or preventing renal cell cancer in a subject, the method comprising administering a composition, which is for treating or preventing renal cell cancer and contains D-allose as an active ingredient, to a subject in need thereof through the intestinal tract (for example, oral administration).

Abstract: Provided is a pharmaceutical composition that is for prevention or treatment of urinary tract organ cancer, causes no adverse side effects, can be continuously used for a long time, and is administered to the urinary tract organ by injection into the urinary tract organ cavity. A solution for injection into the urinary tract organ cavity contains D-allose. The inside of the urinary tract organ cavity is the inside of the upper urinary tract and the inside of the bladder. The solution is for injection therapy into the urinary tract organ cavity. The solution uses enhancement of sugar uptake into cancer cells of the urinary tract organ (for example, RT112, 253J, J82) by D-allose. The solution contains D-allose together with a pharmaceutically acceptable diluent or carrier. The solution is a pharmaceutical composition for prevention or treatment of urinary tract organ cancer.

Abstract: To provide a composition for the treatment of renal cell carcinoma and a composition or a method for enhancing the uptake of a drug into renal cell carcinoma cells. Provided are a D-allose-containing composition for the treatment of renal cell carcinoma, and a D-allose-containing composition or method for enhancing the uptake of a drug into renal cell carcinoma cells. The composition is a pharmaceutical composition to be administered in an effective amount to patients requiring the treatment of renal cell carcinoma in humans or animals other than humans.

Abstract: A preservative solution for low temperature preservation of animal or human organs and animal or plant tissues or cells contains D-allose. For the human kidney, cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum, the preservation is conducted at from ?5 to 20° C. For cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum, the preservation is conducted at a temperature at which to start freezing to ?196° C. A method for the low temperature preservation of an animal or human organ and an animal or plant tissue or cell at a low temperature comprises (a) refluxing or immersing a preservative solution containing D-allose and the organ or the tissue or mixing the cell therewith, and (b) cooling the organ, the tissue or the cell to a low temperature of from ?5 to 20° C.

Abstract: [Problem] To provide a preservative solution for cells, tissues and organs using a rare sugar and a preservation method using the solution. [Means for Resolution] A preservative solution for cryopreservation of animal or human organs and animal or plant tissues or cells, the solution containing a rare sugar D-allose. A preservative solution for cryopreservation of the human kidney, cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum in which the cryopreservation is conducted at from ?5 to 20° C. A preservative solution for cryopreservation of cells derived from animals or humans, or human or animal sperm and/or ovum and/or fermented ovum in which the cryopreservation is conducted at a temperature at which to start freezing to ?196° C.
