  2. 1. Regulation of the exocrine pancreas in growing pigs, with special emphasis on entero-pancreatic reflexes

    Author : Lena Evilevitch; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kidney bean lectin; Animal physiology; Djurfysiologi; duodenum; entero-pancreatic reflex; insulin; lipas; amylas; trypsin; weaning; development; maturation; inhibition; CCK-receptors; Exocrine pancreas; CCK; pig;

    Abstract : The regulation of the exocrine pancreas has been under thorough investigation for many decades. In rats, cholecystokinin (CCK) is considered to be the major gut hormone stimulating the pancreas to releasing the digestive enzymes. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Effect of Cholecystokinin-B/Gastrin Receptor Antagonists on Rat Stomach ECL Cells

    Author : Xi-Qin Ding; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; gastrin; cholecystokinin CCK receptors; ECL cells; CCK-B gastrin receptor antagonists; histidine decarboxylase HDC ; histamine; pancreastatin; chromogranin A CGA ; gastric acid secretion.; cytochemistry; Histology; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The histamine- and pancreastatin- containing ECL cells in the acid-producing mucosa of the rat stomach operate under the control of circulating gastrin. The present work examines how cholecystokinin (CCK)-B/gastrin receptors regulate the activity of the ECL cells. READ MORE

  6. 4. Aspects on the psychopharmacology of cholecystokinin

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

    Abstract : 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. READ MORE

  7. 5. 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
