ＭＣＸ９１２是从蚯蚓中提取的一种活性蛋白，低剂量（１８～２．５Ｇｙ）分次照射条件下的辐射增敏作用，已被动物实验和临床研究所证实。但在单次大剂量照射条件下是否具有抗放作用，为此目的我们进行了初步实验研究。材料与方法：实验动物为纯系ＢＡＬＢ／Ｃ雄性小... MCX912 is an active protein extracted from earthworms. Radiation sensitization under low dose (18 ~ 2.5Gy) irradiation has been confirmed by animal experiments and clinical studies. But in a single high-dose irradiation conditions have anti-letting effect, for this purpose we conducted a preliminary experimental study. Materials and Methods: Experimental animals are purely BALB / C male small ...
