Three commercially available kits for 1,25-dihydroxyvitamin D [1,25(OH)2D] determination were compared with a liquid-chromatographic method. Serum samples were analyzed for 1,25(OH)2D from 70 healthy subjects (age 2.2-17.5 years; 35 males, 35 females), some (n = 5) given orally high vitamin D3 doses. In addition, 1,25(OH)2D was measured in 28 patients with(More)
The action of ergotamine on the 5-hydroxytryptamine (5-HT) venous sensitivity was studied in ergotamine abuser and non-abuser migraine patients. Ergotamine abusers showed reduced 5-HT hand vein contraction during abuse, compared to seven days after ergotamine withdrawal. In non-ergotamine users, the 5-HT venoconstriction was not significantly modified 12 h(More)
The vasoconstrictor activity of sumatriptan and ergotamine were compared by injecting these drugs in the hand vein of migraine subjects. We used the "venotest method", which permits the evaluation of the venoconstrictor effect of small doses of drugs, acting locally in the hand vein. Sumatriptan injected at increasing doses in the hand vein provoked(More)
OBJECTIVE Acute lung injury still accounts for postoperative mortality after cardiopulmonary bypass (CPB). The safety and the efficacy of pulsatile pulmonary perfusion (PPP) during CPB were analyzed. Preliminary results of the first PPP trial in human beings are reported. METHODS Thirty low-risk coronary artery bypass grafting (CABG) patients were(More)
Organizational features of the ipsilateral representation in the cat face motor cortex were investigated by using the technique of intracortical microstimulation (less than 30 microA). In 4 intact animals, 61 efferent zones controlling facial muscles were identified. They were devoted to contralateral muscles (contralateral efferent zones; n = 35),(More)
Extracorporeal life support (ECLS) to manage acute antiarrhythmic drugs toxicity in neonates has never been reported. Here presented is a case of venoarterial extracorporeal membrane oxygenation support in a newborn with refractory low cardiac output as a result of acute Ca-channel and β-receptor antagonist toxicity for treatment of paroxysmal(More)
