[Olinescu A et al:Arch Roum Path Exp Microbiol 39(2):121,1980(英文)] α_2巨球蛋白是人血浆中一种大分子糖蛋白,具有特殊之空间结构。它的生物学功能至今尚未完全确定。曾有报告它对遭受γ射线致死性剂量照射的小鼠有保护作用,能提高其存活率和脾指数,并促进骨髓和脾脏中细胞的再生。本文作者应用体重19～20g的 [Olinescu A et al: Arch Roum Path Exp Microbiol 39 (2): 121, 1980 (English)] α-2 Macroglobulin is a macromolecular glycoprotein in human plasma with a special spatial structure. Its biological function has not yet been completely determined. It has been reported that it has a protective effect on mice exposed to lethal doses of gamma rays, increasing its survival rate and spleen index and promoting cell regeneration in the bone marrow and spleen.
