有人已经指出,艾氏腹水癌小鼠的腹水液中存在着拮抗肿瘤生长的抑素和溶癌因子。1976年以来,北医生化教研室陈明等首先从艾氏腹水癌小鼠的腹水中分离到一种抑癌因子,并与有关单位协作相继进行了报导。本文主要从人癌患者的胸腹水中分离到抑癌因子,并对其活性进行检测,现初步报导如下。 It has been pointed out that the ascites fluid of mice with Ehrlich ascites carcinoma has somatostatin and oncolytic factors that antagonize tumor growth. Since 1976, Chen Ming et al., first of all, have separated a cancer suppressing factor from the ascites of mice with Ehrlich ascites carcinoma, and have reported in collaboration with relevant units. In this paper, we isolated the tumor suppressing factors from the pleural and abdominal waters of human cancer patients and detected their activity. The preliminary reports are as follows.
