1. 1. Effects of nitric oxide on gastric acid secretion in human gastric mucosa : functional and morphological studies

   Författare :Anna Berg; Gunnar Flemström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Hydrochloric acid (HCI) is secreted in high amounts by parietal cells in the human gastric mucosa and the resulting low pH constitutes an important factor for creating a suitable environment for the digestion. The normal gastric mucosa is equipped with an arsenal of protective mechanisms against the extreme chemical environment which the gastric acid creates. LÄS MER

3. 2. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

   Författare :Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
   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. 3. The Gastrin-ECL Cell Axis. Functional Aspects

   Författare :Maria Björkqvist; Institutionen för experimentell medicinsk vetenskap; []
   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. 4. 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

7. 5. Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat

   Författare :Peter Ericsson; Drug Target Discovery; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The ECL cells constitute the major endocrine cell population in the acid-producing part of the stomach. Gastrin from G cells in the antrum is the main stimulus of gastric acid secretion. Gastrin stimulates the ECL cells in the oxyntic mucosa to mobilize histamine, which in turn stimulates the parietal cells to produce hydrochloric acid. LÄS MER
