STUDIES ON THE DISTRIBUTION AND PHOSPHATE TURNOVER OF THE ACID-SOLUBLE PHOSPHORUS COMPOUNDS IN VARIOUS NORMAL AND NEOPLASTIC TISSUES OF RATS. II. COMPARISON OF THE CHROMATOGRAMS OBTAINED WITH VARIOUS TISSUES INCLUDING TUMOURS (ENGLISH TEXT)
Using a modified semi-micro gradient elution method of chromatography, the distribution of the acid-soluble nucleotides in various normal and neoplastic tissues of rats was compared and the variations of the distribution are described. The distribution and phosphate turnover of the acid-soluble phosphorus compounds were also studied by intraperitoneal injection of P/sup 32/ followed by the chromatographic analysis. The distribution patterns of nucleotides and radioactivity in liver, muscle, heart, lung, thymus, spleen, testicles, brain, fetal liver, and experimental hepatomas are illustrated and the differences between these tissues were pointed out. The characteristics of the experimental hepatoma tissue as compared with the normal liver tissue are as follows: The concentration of oxidized DPN was low; the incorporation of P/sup 32/ inorganic phosphate into glucose 6-phosphate and L- alpha -glycerophosphate was absent or, if any, very low; radioactivity of inorganic phosphate in the total acid-soluble radioactivity was extraordinarily high as compared with other tissues besides the liver tissue.
