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

    Author : Håkan Blom; Herbert Helander; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Interdigestive and postprandial small bowel motility : an experimental study in the rat with special emphasis on the effects of vagotomy and neurotensin

  5. 3. Neuro-immune communication: role of the vagus nerve : an electrophysiological study

    Author : Violeta Bucinskaite; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cholecystokinin; CCKA; CCKB; cytokines; IL-1[beta]; illness; nerve activity; NIDDM; OLETF; the vagus; vagotomy;

    Abstract : Defence mechanisms involve close interactions between the nervous and immune systems following an immune challenge. The vagal pathways which modulate major visceral functions under normal conditions are also important neural pathways for the transmission of information on peripheral conditions to the CNS.

  6. 4. Peripherally administered choleocystokinin-8 increases neurotrophins in the brain

    Author : Paola Tirassa; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NGF; BDNF; CCK-8; glutamate; GABA; CCK receptors; hypothamalus; hippocampus; Choline Acetyltransferase; fimibria-fornix transection; vagotomy; vagal stimulation; RT-PCR; ELISA;

    Abstract : The aim of this thesis was to test the hypothesis that the gastric hormone Cholecystokinin-8 (CCK-8) can modulate the production of Nerve Growth Factor (NGF) in the brain. NGF is the first discovered and the best characterized neurotrophic factor which plays a crucial role in the survival and development of basal forebrain cholinergic neurons (BFCN). READ MORE

  7. 5. Role of corticotropin-releasing factor, somatostatin and leptin in vagal nerve function and control of gastric emptying

    Author : Ulrika Smedh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The overall aim of this thesis was to study the effects of centrally acting CRF and leptin, and peripherally acting somatostatin on gastric emptying of glucose. Freely moving rats bearing chronic intragastric fistulas received intragastric infusions (1.0 ml/min) of glucose (12.5 % or 25 %) during 6-18 min. READ MORE
