STUDIES ON THE ASCORBIC ACID METABOLISM OF ANIMALS IN HIGH TEMPERATURE ENVIRONMENT : (II) ON THE ASCORBIC ACID CONTENT AT CONTINUOUS LONG-TIME EXPOSURE TO HOT ENVIRONMENT

Abstract

Guinea pigs were exposed to a hot environment (35℃, 60-65% humidity) for 8 hours daily for 3 weeks. The change of the ascorbic acid content in their various tissues were investigated thereby. A long-time exposure to a hot environment less than 35℃ did not cause a decrease in the ascorbic acid content of the tissues. This finding suggests that the animals might have adapted to a high temperature environment and that a long-time exposure to the treatment might not cause a promotion of ascorbic acid metabolism.
