  1. 1. 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; 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

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

    Author : Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Factors related to the occurrence of gastric adenocarcinoma subtypes

    Author : Anna Mia Ekström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; gastric; cancer; incidence; trend; cardia; Laurén; histologic; misclassification; antioxidant; completeness; vegetable; fruit; occupation; phenoxy; metal; forestry; Helicobacter pylori; smoking;

    Abstract : Gastric cancer is the second most common cancer worldwide, but the etiology remains poorly understood. A spontaneous global decline has reduced the number of victims in most Western countries while Japan and China have screening programs in place due to the magnitude, and the serious prognosis, of this malignant disease.

  4. 4. Aspects on prognosis of cancers of the oesophagus and gastric cardia

    Author : Martin Sundelöf; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Oesophagus; adenocarcinoma; squamous-cell carcinoma; gastric cardia; prognosis; lifestyle factors; palliation; dysphagia;

    Abstract : Oesophageal cancer is an aggressive form of cancer with a poor prognosis. The two main histological types are squamous-cell carcinoma and adenocarcinoma. In the Western world the incidence rate of adenocarcinoma of the oesophagus, previously rather rare, has shown a dramatic increase in recent decades. READ MORE

  5. 5. Clinical Pharmacokinetics of Small Doses of Ethanol : Role of Gastric Emptying and Other Influences in the Upper Gastrointestinal Tract

    Author : Stergios Kechagias; Risto Roine; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : This thesis deals with the clinical pharmacokinetics of small doses of ethanol as influenced by conditions in the proximal gut. The bioavailability of orally administered ethanol depends to a large extent on gastric emptying, which is influenced by pre-treatment with drugs and other clinically relevant factors in the upper gastrointestinal tract.
