Studies were made on the vitamin B_6 contents in various organs of rat caused by subcutaneous injection of pyridoxine hydrochloride. In sound stimulated animals, the vitamin B_6 contents of each organ reached the maximum in 15 minutes after an injection, while in the control animals, it was needed 30 minutes to reach the maximum. The contents, themselves, were higher in the stimulated animals than in the control ones. The most remarkable result was observed in the case of pyridoxal, namely the increase caused by an injection was kept even 60 minutes after. The tendency was more remarkable in the 2 weeks stimulated animals than in the one week stimulation. Urinary vitamin B_6 excretion was also higher in the stimulated rats when 5 μg of pyridoxine hydrochloride was injected per g- of body weight. However, the stimulation did not affect on the ratio of three types of vitamin B_6.
