Abstract
Antibody reacted with urine from cancer patients was produced in the rabbit sera immunized with the urine from gastric cancer patient which inhibited the reaction of anti-gastric cancer immune serum. Specimens of the intact urine from cancer patients showed the direct precipitation reaction with the anti-cancer urine serum by the agar gel diffusion technique, and the reaction of anti-cancer urine serum was inhibited by most of concentrated urine from cancer patients. The reaction was inhibited by D-glucosamine and D-galactosamine as simple sugars just like the reaction of anti-gastric cancer immune serum.
