Abstract
Urinary glucose level of rats was determined before, during, and after the first stress (avoidance conditioning) and the second stress (extinction) period for 65 days. The urinary glucose excretion did not increase during the first stress period. The increase appeared gradually during the second stress period and reached maximum soon after the stress was over. It did not restore completely to the normal level after the stress. It increased in all animals coincidentally with an anxiety behavior. The increase was 120% in average during the second stress, and was 276% at maximum after the stress. An increase in the urinary glucose was brought by the emotional stress, and is related closely to the decreased selection of glucide. Present experiment shows a glucosuria induced by the psychological stimuli, which was persistently resulted long after the termination of stimulation and the disappear·ance of anxiety.
