Studies on the Phosphoric Acid Metabolism of the Brain with Radioactive Isotope (32)P Part 2. The Phosphoric Acid Metabolism of the Rabbit Brain in a State of Latent, Local Anaphylaxis

By pursuing the behaviors of migrating (32)P in the brain and in various phosphoric acid fractions of the rabbits with latent, local cerebral anaphylaxis as well as of normal rabbits after injecting (32)P into the cisterna magna in either case, the author made a comparative study of the phosphoric acid metabolism in the brains of the two groups from the different behaviors of (32)P. In the case of the rabbits with latent, local cerebral anaphylaxis besides an increase in the rate of (32)P migration to inorganic phosphoric acid fractions and phosphoprotein fractions, a marked decrease in the rate of (32)P migration to phospholipid fractions can be observed as compared with that in normal rabbits. It is to be considered that on the whole the phosphoric acid metabolism in the brain of the rabbits with latent, local cerebral anaphylaxis shows a declining tendency.
