一.引言治疗癌症的主要方法有三种:外科手术,放射疗法和化学疗法。但近十余年来世界上普遍认为癌的免疫疗法是更为优越的方法。所谓免疫疗法就是刺激人体非特异性防御机能,特别是在机体的免疫功能受损伤酌情况下刺激宿主免疫系统以达到防治疾病的目的。寻找免疫促进剂是当今发展新药的方向之一。实际上,这种治疗方法过去已经使用,但未受到象现在那样重视。例如注射人体自身血液或牛奶蛋白质,注射去活性的大肠杆菌,或诸如芥末油之类的特殊发炎剂,以及后来发展起来的免疫增强剂卡介苗(常称BCG)等。多糖作

Such as the injection of human body’s own blood or milk protein, injection of deactivated E. coli, or special inflammatory agents such as mustard oil, as well as the subsequent development of BCG as an immunopotentiator.
