恶性肿瘤是一个常见病,它严重威胁着人类的健康。许多科学工作者,从不同的学科和角度来研究肿瘤的生物化学和代谢的特点,但遇到的主要困难,是癌细胞与正常细胞之间,在生化成份上只有量的差别,而质的差异不很突出,迄今尚未被人们所充分认识。因此,要寻找亲肿瘤的,有特异性的标记化合物,自然有一些困难。尽管如此, Malignant tumors are a common disease that seriously threatens human health. Many scientists have studied the characteristics of the biochemistry and metabolism of tumors from different disciplines and perspectives, but the main difficulty encountered is the difference in the amount of biochemical components between cancer cells and normal cells. The differences are not very prominent and have not yet been fully understood by people. Therefore, to find a pro-tumor, there are specific marker compounds, naturally there are some difficulties. despite this,
