3H-p-Aminoclonidine binding to platelets of children and adolescents with major depressive disorder was compared to that of a healthy control population. Significantly higher alpha 2-adrenoceptor Kd and Bmax values were observed in the patient population. 3H-Dihydroalprenolol binding to lymphocyte membranes of the same patient population showed(More)

Levels of plasma norepinephrine (NE), free 3-methoxy-4-hydroxyphenylglycol (MHPG), and cortisol in adolescents with major depressive disorder (10 girls, 1 boy; mean +/- SD age = 16.4 +/- 1.6 years, range = 14-19 years) did not differ significantly from those in a group of healthy adolescents (17 girls, 12 boys; mean +/- SD age = 15.9 +/- 1.5 years, range =(More)
