Studies on the plasma tryptophan and urinary 5-hydroxy-3-indoleacetic acid in expedition members residing in Antarctica
In order to clarify the possible relationship between the changes of behavior/personality and metabolic changes of 5-hydroxytryptamine (5-HT) in Antarctic expedition members, plasma tryptophan (Trp) and urinary 5-hydroxy-3-indoleacetic acid (5-HIAA) were studied for 24 winter-over and 19 summer-over...
