美国研制出一种能早期发现癌症的新型诊断用药。据报道,此种药物属单色抗体,它具有寻找癌细胞并与之结合的特性,即使是很小的肿瘤也能灵敏地探出。该药目前已用作直肠癌、结肠癌及肝癌临床试验阶段的诊断用药。将具有某种与特定癌细胞结合功能的单色抗体与锝等放射性同位素结合,将此诊断用药用大自鼠作试验。用药后即聚集于肿瘤部位。用医学检查中比较普
The United States has developed a new diagnostic drug that can detect cancer early. According to reports, the drug is a monochromatic antibody that has the property of finding and binding to cancer cells. Even small tumors can be detected with sensitivity. The drug has been used as a diagnostic drug for clinical trials of rectal cancer, colon cancer, and liver cancer. A single-color antibody having a certain function of binding to a specific cancer cell is combined with a radioisotope such as cesium, and the diagnostic drug is tested with a large mouse. After treatment, it accumulates at the tumor site. Compared with medical examination
