VITAMIN B_6 METABOLISM IN HIGH TEMPERATURE EMVIRONMENT : (II) CHANGES OF THE CONTENTS OF VITAMIN B_6 AND PYRIDOXIC ACID IN THE INTERNAL ORGANS OF RABBITS AT HIGH TEMPERATURE

Abstract

Pyridoxine+pyridoxamine, pyridoxal and pyridoxic acid were determined in liver, kidney and brain of rabbits exposed to high temperature. Noticeable changes were not recognized by the exposure to 3 hours at 30 and 35℃, but at 37℃ vitamin B_6 content of the each organ and pyridoxic acid content of liver decreased. Decreases of vitamin B_6 and pyridoxic acid were recognized after the exposure to 12 hours at 30℃ or 48 hours at 35℃ in each organ, by the ordor of brain, kidney, liver, and pyridoxic acid, pyridoxal, pyridoxine+pyridoxamine
