title: Serotonin (5-HT) uptake by blood platelets in anorexia nervosa.
abstract: Platelet serotonin (5-HT) uptake was determined in 15 underweight anorexia nervosa patients and a control group of 15 healthy individuals. The Vmax (picomoles/10(8) platelets/5 min) was 424 +/- 103 in patients and 424 +/- 69 in controls. The Km was 1.19 +/- 0.2 microM in patients and 1.08 +/- 0.17 microM in controls. The differences between the groups were not significant. These findings do not support the hypothesis that serotonin metabolism is disturbed in anorexia nervosa.
