Effect of a nutritive-tonic drink on stress-induced serum glucocorticoid in the mouse.
We evaluated stress during "restraint with gnawing (R+G+)" and "restraint without gnawing (R+G-)" in a mouse system. R+G- induced a higher serum glucocorticoid level than R+G+. Zena F-III (a nutritive-tonic drink prescribed as "Kampo", a traditional Japanese medicine with its origin in Chinese medicine) reduced the glucocorticoid elevation in R+G+, but not in R+G-. These results support the hypotheses that (i) activity, such as gnawing, which potentially leading to escape from distress, reduces the severity of emotional distress and (ii) Zena F-III reduces the severity of mental or emotional fatigue, or increases motivation, in a stressful situation that the animal can manage itself.
