Serum melatonin and urinary 6-sulfatoxymelatonin in major depression.

In this study, serum melatonin and urinary 6-sulfatoxymelatonin (aMT6s) were measured in 14 major depressive inpatients, compared to 14 matched controls according to age, gender, season and hormonal treatment in women. Moreover, the relationship between serum melatonin and urinary aMT6s levels was analysed in the two groups. Results indicated that the two groups of subjects showed a clear melatonin rhythm without significant difference in the mean level of melatonin or aMT6s, in the area under the curve of melatonin or in the melatonin peak.

Temperament and character inventory (TCI) and depression.

Although several studies have assessed the relationships between the temperament dimensions of the Cloninger model of personality and depression, little is known about the role played by the character dimensions proposed by the seven-factor model of Cloninger in depression. In this study, the relationships between the Temperament and Character Inventory (TCI) and depression were examined in a sample of 40 major depressive patients and 40 healthy controls. Depressed patients exhibit higher harm avoidance and self-transcendence scores as well as lower self-directedness and cooperativeness scores as compared to healthy controls.
