Abstract Quantitative assessment of the nucleic acid content in preparations stained with gallocyanin and chrome alum was carried out in 20 cases of gastric carcinoma. Coefficients representing the ratios between DNA+RNA of the nucleus and RNA of the cytoplasm and between DNA of the nucleus and the total RNA in the nucleus and cytoplasm, and the index of DNA accumulation were compared in adenocarcinomas and in undifferentiated carcinomas of the stomach. The ratio between the area of nucleus and cytoplasm and the ratio of DNA+RNA of the nucleus to RNA of the cytoplasm were statistically significantly higher in the adenocarcinomas than in the undifferentiated gastric carcinomas. This suggests a lower level of differentiation of the adenocarcinoma of the cells than of tumor cells from undifferentiated forms of gastric carcinoma.
