Anti-radiation drugs refer to drugs for protection against nuclear radiation damage. At present, there are Chinese herbal medicines, such as ginseng, Ganoderma lucidum, Rhodiola rosea, etc.; free radical scavengers, such as WR-2721 (S-2-(3-aminopropylamino)ethylthiophosphate); and anti-radiation cytokine biochemicals, which are mainly interleukin-like cytokines, such as IL-1, IL-6, and IL-11, etc. 1. 1. Herbal medicines: ginseng, ganoderma lucidum, rhodiola rosea, etc., which have the functions of enhancing immunity and improving hematopoiesis, as well as improving the antioxidant capacity of the body and inhibiting the activity of free radicals, thus effectively reducing DNA damage and enhancing DNA repair. 2. Free radical scavenger compounds: WR-2721 (S-2-(3-aminopropylamino) ethyl phosphorothioate), which binds with free radicals through their unsaturated bonds or redox reactions, thus eliminating or attenuating radiation damage. 3. Anti-radiation cytokine biochemical drugs: mainly interleukin cytokines such as IL-1, IL-6 and IL-11. IL-1 can effectively remove free radicals and reduce radiation damage; IL-6 can significantly reduce reactive oxygen radicals in normal tissues and play a protective role against radiation by reducing the degree of free radical damage; IL-11 has the ability to improve hematopoietic function, thereby increasing peripheral blood cells. If a person is irradiated by nuclear radiation, he or she should be taken to a hospital immediately and treated under the guidance of a doctor without delay, so as not to jeopardize his or her life.
