Studies on the Fluorescent Substance in Gastric Juice from Patients Suffering from Stomach Carcinoma

Abstract

Abstract: This paper reports a characteristic fluorescent substance in gastric juice from the patients suffering from stomach carcinoma and its probable existance form. The systematic separation for the gastric juice with stomach carcinoma was carried out by biochemical methods. The comparisons of the fluorescence spectra and excited spectra of the gastric juice with stomach carcinoma with that of the aqueous solution of riboflavin and the experiments based on the properties of riboflavins make us come to the conclusion that the characteristic fluorescent substance in the gastric juice from the patients of stomach carcinoma is riboflavin-binding protein and probably exists in phospholipid membrane.

Key words: Gastric juice, Riboflavin, Fluorescence
