  1. 1. Physiological and pathophysiological regulation of ECL-cell activity

    Detta är en avhandling från Institute of Experimental Medical Sciences

    Författare :Maria Lundgren; Lund University.; Lunds universitet.; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy; toxicology; Pharmacological sciences; pharmacognosy; Gastroenterologi; endothelin; gastrin; ischemia-reperfusion; Physiology; Fysiologi; Gastro-enterology; pancreastatin; histamine; microdialysis; ECL-cell; stomach; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin A-derived peptides in response to circulating gastrin. Mobilized histamine stimulates acid secretion from adjascent parietal cells. LÄS MER

  2. 2. Biological significance of ECL-cell histamine

    Detta är en avhandling från Department of Pharmacology, Lund University

    Författare :Kjell Andersson; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; ultrastructure; gastric acid secretion; a-fluoromethylhistidine a-FMH ; stomach; oxyntic mucosa; histidine decarboxylase HDC ; Enterochromaffin-like ECL cell; histamine; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : In the oxyntic mucosa of the mammalian stomach, histamine is stored in enterochromaffin-like (ECL) cells and in mucosal mast cells. The activity of the histamine-forming enzyme, histidine decarboxylase (HDC), is high in ECL cells but lower in the mucosal mast 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 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

  5. 5. Histamine and chromogranin A-derived peptides in rat stomach ECL cells

    Detta är en avhandling från Per Norlén, Dept. of Pharmacol. Sölveg. 10, S-22362 Lund, Sweden

    Författare :Per Norlén; Lund University.; Lunds universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacy; pharmacognosy; Pharmacological sciences; CGRP adrenaline; galanin; VIP; PACAP; somatostatin; gastrin; microdialys; pancreastatin; chromogranin A; histamine; ECL cell; rat stomach; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : The ECL cells constitute the predominant endocrine cell population of the stomach. They secrete histamine which is a major stimulator of acid secretion. Chormogranin A (CgA)-derived peptides, such as pancreastatin, are co-secreted with histamine. LÄS MER
