BACKGROUND Fifteen (+/-)3,4-Methylenedioxymethamphetamine (MDMA) users, who did not show other drug dependencies or prolonged alcohol abuse, and 15 control subjects were included in the study. METHODS Prolactin (PRL) and cortisol (CORT) responses to the serotonergic agonist d-fenfluramine (D-fen), clinical psychobehavioral changes, and psychometric(More)
Neurotransmitter-neuroendocrine and cardiovascular responses to the administration of a psychologically stressful mixed-model test (Mental Arithmetic, Stroop Color Word Interference Task, Trier Social Stress Test) were examined in 20 male peripubertal subjects affected by anxiety disorder (group A: 14 with generalized anxiety disorder, 6 with generalized(More)
Correlations between sensation-seeking (SS) personality dimension and plasma concentrations of norepinephrine (NE), epinephrine, and NE-dependent testosterone (T), cortisol and prolactin (PRL) were studied in 74 physically and psychologically healthy male volunteers, in order to see whether or not the noradrenergic system is involved in the modulation of(More)
PURPOSE Studies investigating temperament traits of drug abusers and their biological correlates have disclosed high rates of novelty seeking (NS) in opiate addicts, possibly based on dysfunctions of the dopaminergic (DA) system. The aims of the present study were to see whether or not the monoamine functions were impaired in detoxified addicts and whether(More)
Previous studies of hormonal and neurophysiological changes in response to psychological stress in humans have produced contrasting findings due to differing experimental procedures and consistent individual variability. Habituation effects, which influence physiological coping in response to exposure to repeated stress, need to be investigated more(More)
Studies investigating temperament traits in humans and their biological correlates have found high levels of novelty seeking (NS) linked with dopaminergic system changes, and particularly a deficit of dopamine transporter. Harm avoidance and reward dependence, on the other hand, appeared to be associated, respectively with serotonin and noradrenaline(More)
OBJECTIVE This study was conducted to determine the nature of the reaction of nonalcoholic adult children of alcoholic (ACOA) fathers to the experimental induction of aggression. Of particular interest was the relationship between biochemical factors and personality traits during a stressful event experienced by persons at risk for alcoholism. METHOD(More)
by the Color Doppler ultrasound. The endocrinological testicular function was preserved. Unfortunately, both patients were diagnosed with complete azoospermia with histological tubular sclerohyalinosis. The postoperative stretched penile measurement demonstrated a real penile lengthening of 1.5 cm in both cases, which was found acceptable by both patients.(More)
