Strips of human pulmonary arteries from patients undergoing surgery for lung tumour were incubated with [3H]-noradrenaline. Subsequently, they were superfused with physiological salt solution containing cocaine and corticosterone. Tritium overflow from the strips was stimulated by transmural electrical impulses (2 Hz). The electrically evoked overflow of(More)
Strips of human saphenous veins were incubated with [3H]noradrenaline and subsequently superfused with physiological salt solution containing cocaine, corticosterone and propranolol. The electrically (6 Hz) evoked overflow of tritium (78% of which was accounted for by unmetabolized [3H]noradrenaline) was abolished by tetrodotoxin or omission of Ca2+ from(More)
We used strips of human pulmonary arteries from patients undergoing surgery for lung tumor to investigate whether or not this human tissue (like that of the rabbit) is endowed with inhibitory presynaptic alpha 2-adrenoceptors. The strips were incubated with [3H]noradrenaline and subsequently superfused with physiological salt solution containing cocaine,(More)
The Council Directive of the European Communities 97/43/Euratom requires dose assessment, especially for X-ray examinations of children and if high doses to the patient are involved. Both these aspects apply in cardiac catheterization and angiocardiography of children. Effective doses are a good indicator of radiation risk, particularly for leukaemia.(More)
Strips of the rabbit pulmonary artery were incubated with 3H-noradrenaline and subsequently superfused. In strips superfused with Ca2+-free solution containing K+ 64.7 mmol/l, tritium overflow was stimulated by introduction of Ca2+ 1.6 mmol/l; in strips superfused with physiological salt solution, stimulation was carried out with veratridine 30 mumol/l,(More)
We investigated the urinary tract in 19 out of 30 children having the Williams-Beuren-Syndrome. 14 of these children showed all signs of the syndrome, whereas 8 children had only the typical cardiological findings without the pathognomonic facies and without major mental retardation. These two different types will be designed as type I and type II(More)
Balloon valvuloplasty (BVP) of pulmonary stenosis (PST) was performed in 305 infants and children in 20 heart centres of the Federal Republic of Germany. 273 patients suffered from isolated PST. Their age ranged from 3 days to 18 years (mean = 5.85 +/- 4.82 years), their weight from 2.9 to 60 kg. The pressure gradient was measured invasively in the sedated(More)
Description and discussion of the findings in a five month old infant and a six year old boy, in whom unilateral absence of the pulmonary artery contralateral to the aortic arch could be demonstrated by means of angiocardiography. The infant, having absence of the right pulmonary artery associated with patent ductus arteriosus and obstructive pulmonary(More)
The diagnosis "innocent murmur" is made when there is no evidence for a heart disease either by history nor by examination, auscultation, electrocardiogram or echocardiography. The purpose of the present study was to determine the usefulness of echocardiography for diagnosing of an innocent heart murmur and further to compare the findings of ultrasound with(More)
Description of the history, the clinical findings, and the autoptic results in a 5-days-old newborn child with a truncus arteriosus (Type I) and an interrupted aortic arch (Type B). Perfusion of the distal aortic arch by a wide open Ductus arteriosus. Additional anomalies: Atrial septal defect with partial anomalous pulmonary venous drainage of the right(More)
