绿十字社和美国田纳西大学,共同进行了只对癌细胞具有特异作用的糖蛋白抗癌剂的研制工作。他们从人尿中把尿激酶分离精制,并作为血栓溶解剂销售于市场,而用这个生产过程又发现了新的糖蛋白质,是分子量为2～4万的生理活性物质。如果根据田纳西大学的试管内试验,它对人的正常细胞没有作用,而对乳腺癌、肺癌等的癌细胞增殖具有显 Green Cross and the University of Tennessee in the United States have jointly developed glycoprotein anticancer agents that have specific effects on cancer cells. They isolated and purified urokinase from human urine and marketed it as a thrombolytic agent. With this production process, a new glycoprotein was discovered, which is a physiological active substance with a molecular weight of 2 to 40,000. According to the in vitro test at the University of Tennessee, it has no effect on human normal cells, but it has significant effects on the proliferation of cancer cells such as breast cancer and lung cancer.
