prolamine/atrophy

The entero-insular hormonal axis was studied in eleven conscious Beagle dogs, loaded with glucose orally and intravenously. In five of them, exocrine pancreatic atrophy was induced by pancreatic duct occlusion with prolamine, and documented by means of the p-amino-benzoic acid test. After oral

The effect of the occlusion of the pancreatic duct system with prolamine (Ethibloc) has been studied in animal experiments with dogs and mini-pigs. The solution becomes solid in the duct system and becomes disintegrated again within 11 days. This time, however, is sufficient to keep a high-grade

Prolamine is an alcoholic solution of zein, with the property of polymerizing within 15 minutes in a humid medium. Such a substance has been injected in the pancreatic duct of 10 pigs with a microsurgical technique, causing complete occlusion. The prolamine gel produces a progressive fibrosclerosis

The response of the pancreatic islet A- and B-cells after long-standing (eight years) pancreatic duct occlusion by prolamine, and subsequently developed acinar atrophy, was studied in five beagles, and the results compared with those in six sham-operated dogs. Intravenous arginine infusion (A-cell

Celiac disease is an immunologically mediated enteropathy of the small intestine, characterized by lifelong intolerance to the gliadin and related prolamines from wheat and other cereals, that occurs in genetically predisposed individuals. Symptoms result from structural damage to the mucosa of the

Duct-occluded segmental-pancreas transplants develop progressive fibrotic atrophy, even though endocrine function seems to be unaffected. To determine end-stage size of the graft and to evaluate magnetic resonance imaging (MRI) and computed tomography (CT), these imaging techniques were applied in

Four modifications of dealing surgically with the remaining pancreas after resection of the pancreatic head were compared to each other in dogs. Insulin response and corresponding blood sugar levels were controlled, the remaining pancreas was examined histologically. The obstruction of the

Graft morphology and endocrine function following vascularized pancreas transplantation by different surgical techniques were determined in streptozotocin-diabetic rats. Eight different surgical techniques were studied. Intestinal drainage of exocrine secretion was accomplished by

In a total of 18 'Göttingen' mini-pigs we studied basal glucose in the peripheral plasma, and the hormones insulin, glucagon, and somatostatin in the peripheral and portal plasma, as well as in extracts of pancreatic tissue, both in animals subjected to pancreatic duct occlusion with prolamine (Occ

Although duct obliteration is a safe and effective method for ablation of exocrine secretion in segmental pancreas transplantation, it remains to be clarified whether its effects are restricted to the exocrine tissue. In 20 dogs (beagles 9-15 kg) the right lobe of the pancreas was removed and the

Celiac disease is an inflammatory disorder of the small intestine induced by intake of wheat gluten and other prolamines in genetically susceptible individuals. This disease is manifested by an increased number of intraepithelial and lamina propria lymphocytes, villous atrophy, tissue remodeling and

Intolerance of gluten, resposible for Coeliac disease, is essentially shown by an auto-immune enteropathy, even if the cutaneous manifestation (herpetiform dermatitis) and perhaps certain neurological signs (cerebral syndrome, peripheral neuropathy) may be independent as well as associated with the
