  1. 1. The Gastrin-ECL Cell Axis. Functional Aspects

    Detta är en avhandling från Maria Björkqvist, Department of Physiological Sciences, Pharmacology, BMC F13, 221 84 LUND

    Författare :Maria Björkqvist; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; Calcium channels; CCK receptor antagonists; Misoprostol; Galanin; Somatostatin; Pancreastatin; Histamine; VIP; Gastrin; PACAP;

    Sammanfattning : The ECL cells constitute a prominent endocrine cell population in the acid-producing part of the stomach. They are controlled by circulating gastrin released from G-cells in the antrum. In response to gastrin, they secrete histamine, that in turn stimulates the parietal cell to secrete acid. LÄS MER

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

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Xi-Qin Ding; Lund University.; Lunds universitet.; [1997]
    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. 3. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Rebecca Gagnemo Persson; Lund University.; Lunds universitet.; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; rat; chicken; parathyroid gland; stomach; vitamin D; PTH; CT; calciotropic hormones; Gastrin; calcium; ECL cell; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Sammanfattning : Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. LÄS MER

  4. 4. The Role of CCK-A and CCK-B Receptors in the Trophic Control of Pancreas and Oxyntic Mucosa in the Rat

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Anna-Greta Nylander; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; trophic effects; rats; portacaval shunt; oxyntic mucosa; gastrin; Cholecystokinin; enterochromaffin-like ECL cells; CCK-A CCK-B receptor; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Cholecystokinin (CCK) and the related hormone gastrin have been claimed to exert trophic effects in the pancreas and gastrointestinal tract. Two types of receptors for CCK and gastrin are known to exist, the CCK-A and the CCK-B receptor. They differ in their affinty for CCK and gastrin. LÄS MER

  5. 5. Secretory activity in isolated rat stomach ECL cells

    Detta är en avhandling från Erik Lindström, Dept. of Pharmacology, Sölvegatan 10, 223 62 Lund, Sweden

    Författare :Erik Lindström; Lund University.; Lunds universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; Calcium channels; Adrenaline; Pancreastatin; Prostaglandin E2; Galanin; Somatostatin; Histamine; Gastrin; VIP; PACAP; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid.
