1. 1. CCK-dependent pancreatic regulation and pancreatic functional impact on growth in young pigs

   Författare :Sofia Rengman; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pancreatin; pig; exocrine pancreatic insufficiency; pancreatic duct ligation; insulin; entero-pancreatic reflex; CCK-receptors; pentagastrin; Exocrine pancreas; cholecystokinin;

   Sammanfattning : The exocrine pancreas is mainly regulated via neuro-hormonal pathways. CCK-dependent regulatory pathways and CCK-receptor subtype involved seem to differ between mammalian species. LÄS MER

3. 2. Aspects on the psychopharmacology of cholecystokinin

   Författare :Diana Radu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cholecystokinin; brain; tripeptidyl-peptidase II; CCK receptors; schizophrenia; anxiety; stress; rat; monkey; human; pentagastrin; C-peptide; mRNA;

   Sammanfattning : This thesis includes studies of the effect of mild stress on brain cholecystokinin (CCK), anatomy of markers for CCK-ergic transmission in the brain and the systemic effect of CCK receptor stimulation in a clinical test for anxiety and fear. CCK is a brain-gut peptide acting as a neurotransmitter in mammalian brain via CCKA (CCK1) and CCKB (CCK2) receptors. LÄS MER

4. 3. Chromoendoscopy with particular reference to a modified endoscopic Congo red test

   Författare :Ervin Toth; Gastroenterologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastroenterologi; Gastro-enterology; therapy; diagnosis; gastrointestinal endoscopy; Chromoendoscopy; Congo red;

   Sammanfattning : Chromoendoscopy, endoscopic tissue staining, is an adjunctive method using chemical agents applied to the mucosal surface in order to aid gastrointestinal endoscopic diagnosis and therapy. Acid producing mucosa in the GI tract may be visualized endoscopically by Congo red staining in combination with stimulation of gastric acid production. LÄS MER

5. 4. Parietal cell regeneration in rat gastric mucosal wounds : a quantitative light and electron microscopical study

   Författare :Håkan Blom; Herbert Helander; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; gastric mucosa; gastric wounds; parietal cells; re­generation; pyloroplasty; truncal vagotomy; antrectomy; pen­tagastrin; cimetidine; carbacholine; stereology; light microscopy; electron microscopy; pH-studies;

   Sammanfattning : The aims of the study were to obtain a method with which it would be possible to produce standardized wounds in the gastric mucosa, and to follow the regeneration of the acid producing parietal cells in those lesions during different experimental conditions. Quantitative methods applied to light and electron microscopy were used. LÄS MER

7. 5. Secretory and anti-inflammatory actions of some gastro-intestinal hormones in salivary glands

   Författare :Hülya Çevik Aras; Göteborgs universitet; []
   Nyckelord :salivary glands; protein secretion; synthesis; inflammation; β-defensins; myeloperoxidase; cholecystokinin; gastrin; melatonin; nitric oxide; nerve stimulation;

   Sammanfattning : Textbooks generally state that the secretory activity of salivary glands is solely regulated by nerves. This view is challenged in the present Thesis, using the parotid gland of the anaesthetized rat as experimental in vivo model. LÄS MER
