Angel yeast polysaccharide is said to be a professional anti-radiation product approved by the state? Who used it? Tell me about the effect. urgent

Yeast polysaccharide is a multifunctional factor, which has the functions of regulating immunity, antivirus and antitumor. As early as 1939, Weicker et al. observed that yeast autolysate could improve the decrease of white blood cell count in irradiated mice. In the subsequent study, it was found that yeast nucleic acid and its hydrolysate were related to this effect. Yeast polysaccharide has a good protective effect on irradiated white blood cells and red blood cells. An experiment by the US Air Force showed that yeast polysaccharide can protect air force pilots from radiation damage.

A large number of studies have shown that some antioxidants (such as yeast selenium, vitamin C, vitamin E, β -carotene and some flavonoids) have certain protective effects on biological radiation damage. Yeast polysaccharide has a good protective effect on radiation damage. Yeast polysaccharide is a new functional factor yeast extracted by modern biotechnology, which mainly contains dextran and mannan. Studies have shown that dextran can inhibit the increase of NO and the decrease of SOD caused by TAA oxidative damage. Experts believe that dextran can enhance hematopoietic activity (including the production of granulocytes, monocytes and red blood cells), so its anti-radiation effect is related to promoting hematopoietic function. However, mannan in yeast polysaccharide can adsorb toxins produced by radiation in vivo, and mannan and dextran have synergistic effect.
