Aims/hypothesis. Our aims were to investigate the concentrations and prevalence of autoantibodies against the Mr 65.000 isoform of glutamate decarboxylase (GAD65) and the tyrosine phosphatase-like protein (IA-2) in adults and to test the hypothesis that GAD65 and IA-2 autoantibodies in a regional population are related to abnormal oral glucose tolerance.(More)
BACKGROUND Treatment of coeliac disease (CD) requires lifelong adherence to a strict gluten free diet (GFD) which hitherto has consisted of a diet free of wheat, rye, barley, and oats. Recent studies, mainly in adults, have shown that oats are non-toxic to CD patients. In children, only open studies comprising a small number of patients have been performed.(More)
Infant feeding history was investigated in 72 celiac and 288 age-matched reference children in a retrospective questionnaire study. The reply rate was 100% in celiac and 91.6% in reference children. The celiac children were breast-fed for a significantly shorter time than reference children, and they were less often breast-fed at the introduction of gluten.(More)
Twenty-seven infants who survived intensive care during early infancy in the pioneering period of neonatal intensive care (1956-1965) were investigated after 8-17 years. The selection criterion was maintenance of a tracheotomy for more than 15 days during the first 12 months of life. A variety of clinical, physiological, radiological and psychiatric(More)
Experiments were performed on 4 non-anaesthetized dogs with chronic gastric fistulae. Gastric tonus was studied by volume and inflow rate recording at low pressure heads. Gastric tonus was not affected by propranolol or phentolamine. It was markedly reduced by atropine, presumably by blocking excitatory cholinergic nervous activity. Guanethidine induced a(More)
Experiments were performed on anaesthetized dogs. Vagotomy was followed by an increase of gastric tone. The phasic responses of gastric tone to efferent vagal electrical stimulation were not separable in these experiments as they are in cats. Oesophageal distension, however, produced a marked gastric relaxatory response, which, as in cats, was(More)
