A carcinogenesis inhibitor having no side effect and having an excellent effect by oral administration. A carcinogenesis inhibitor containing a hydantoin derivative or a pharmaceutically acceptable salt thereof as an active ingredient shows an inhibiting action for polyp formation and for cell proliferation, and has no side effect and highly safe whereby it is very highly useful as a pharmaceutical agent and a food such as supplement which prevent the occurrence and progress of cancer, inhibits the recurrence and metastasis of cancer and further achieves the therapeutic effect.

Carcinogenesis inhibitor

In an electrodeposition treatment of an iron-group metal ion-containing liquid, without being influenced by the properties of the iron-group metal ion-containing liquid, iron-group metal ions are efficiently removed from the liquid by precipitation. An anode chamberA provided with an anodeand a cathode chamberA provided with a cathodeare separated from each other by a cation exchange membrane, an iron-group metal ion-containing liquid is charged into the anode chamberA, a cathode liquid is charged into the cathode chamberA, and by applying the voltage between the anodeand the cathode, iron-group metal ions in the liquid in the anode chamberA are moved into the liquid in the cathode chamberA through the cation exchange membrane, so that an iron-group metal is precipitated on the cathode

Treatment method and treatment apparatus of iron-group metal ion-containing liquid, method and apparatus for electrodepositing Co and Fe, and decontamination method and decontamination apparatus of radioactive waste ion exchange resin
