抄録

Some reports had been made of the decrease in the level of the total thiamine in brain under the noise condition.<br>The author intended to investigate the thiamine metabolism of brain and liver, using rats and rabbits, in connection with the disturbance of glycolysis of diencephalon in exposure to noise as had been mentioned previously.<br>The noise condition was the same as that in the previous report. As to the periods of exposure to noise, the animals were divided into 3 groups; 3 hours once, 8 hours/day twice, and 8 hours/day 5 times.<br>As the results, the decrease in the level of the total thiamine in brain was not observed. But the level of the total thiamine in liver decreased in the 8 hours/day 5 times group.<br>Therefore, it is said that the diencephalic dysfunction in exposure to noise is not closely related to the thiamine metabolism.
