12종의 암 조직을 분석한 결과 지용성 아미노산인 트립토판이 대조군에 비해서 8배나 많았고 황과 인 및 철은 $80{sim}1,400$배나 많았으며 구리와 아연은 아주 적게 들어 있었다. 이들 영양성분들이 암 조직 단백질의 거대화와 비정상적인 조직증식에 관여할 가능성이 있을 것으로 추정된다.
In order to investigate the nutrients, such as amino acids and minerals concerned to propagate the cancer cells, cancerous tissues such as neuroblastoma with liver meta, cancer in situs. CIS, meta. squ. cell cancer, R/O squ. cell cancer, macro. RIF, metastatic papillary cancer. neck, stomach cancer, lung cancer, intestinal obs., 3 kinds of rectal cancers were analyzed. Tryptophane, a fat soluble amino acid, and minerals such phosphorus, sulfur and iron were contained exceptionally high in cancerous tissues than that of normal cells. And copper and zinc minerals were contained very low level in cancerous cells. Therefore, we can deduce that those constituents might be concerned to the formation of cancerous tissues.
