The protective effect of polysaccharides of Huangmo (a kind of mushroom) (PSH) given preventively to mice exposed to X rays on their 30 day survival rate and immunologic function was observed. The results show that PSH increased the 30 day survival rate in mice exposed to a lethal dose of X rays, with the protection index being up to 1.72, which suggest that the protective effect of PSH is similar to that of polysaccharides of Ginseng. In addition, in mice exposed to a dose of 2.0 Gy, PSH significantly enhanced the ability of splenocytes to produced IL 2 and γ IFN, activated splenic NK cells, and speeded up the progression of cell cycle in thymocytes, which suggest that for PSH, there may be a certain protective effect on mice exposed to X rays, with enhancing their immunologic function significantly.
