  1. 16. Effect of Cholecystokinin-B/Gastrin Receptor Antagonists on Rat Stomach ECL Cells

    Författare :Xi-Qin Ding; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Helicobacter pylori infection and associated stomach pathology in the adult general population

    Författare :Tom Storskrubb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The discovery of H. pylori infection has had a tremendous impact on the understanding and treatment of upper gastrointestinal diseases. It causes gastritis, sometimes developing to atrophy and intestinal metaplasia (IM), both considered as premalignant conditions and it is an important risk factor for peptic ulcer and non-cardia gastric cancer.

  4. 18. Helicobacter pylori associated effects on inflammatory radical formation and angiotensin II receptors in the stomach

    Författare :Anders Elfvin; Göteborgs universitet; []
    Nyckelord :Helicobacter pylori; Mongolian gerbil; gastric adenocarcinoma; nitro-radical; iNOS; nitric oxide; nitrotyrosine; oxy-radical; myeloperoxidase; angiotensin II; AT1R; AT2R;

    Sammanfattning : Helicobacter pylori infection of the stomach always results in mucosal inflammation and a marked systemic immune response. Despite the profound host defence reactions the bacterium avoids elimination and persists in the mucosa. This results in chronic inflammation and an increased risk for peptic ulcers and adenocarcinoma. LÄS MER

  5. 19. Differential maturation of Na+,K+-ATPase in the rat : transcriptional regulation by glucocorticoids

    Författare :Zheng-Ming Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :glucocorticoids; ontogeny; Na ; K -ATPase; H ; K -ATPase; iontransporter; kidney; lung; heart; stomach; colon.;

    Sammanfattning : Na+,K+-ATPase is a ubiquitous transmembrane enzyme that creates the electrochemical gradient across the cell membrane. Na+,K+-ATPase activity is low in many immature tissues. LÄS MER

  7. 20. Functional role of a constitutively active dioxin/Ah receptor in a transgenic mouse model

    Författare :Patrik Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dioxin Ah receptor; TCDD; dioxin; stomach tumor; osteopontin; peritoneal B1 B cells; transcription factor; gene expression;

    Sammanfattning : The dioxin/ Aryl hydrocarbon receptor is a ligand-activated transcription factor that mediates most (if not all) of the toxic effects of the group of highly potent environmental pollutants collectively called dioxins and PCBs, including the highly toxic compound 2,3,7,8tetrachlorodibenzo-p-dioxin (TCDD). The toxic effects include immune suppression, endocrine disruption, impaired reproduction and carcinogenesis. LÄS MER
