1. 6. Regulation of experimentally induced airway obstruction

   Författare :Eva G. Lindström; Jan Lötvall; Linköpings universitet; []
   Nyckelord :airway obstruction; antigen; capsaicin; epithelium; inflammatory mediators; sensory neurons; tube preparation; tachykinins; formoterol; histamine; presynaptic inhibition; in vitro; guinea pig; MEDICINE; MEDICIN;

   Sammanfattning : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. LÄS MER

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

   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

4. 8. Function of granulocytes after burns and trauma, associations with pulmonary vascular permeability, acute respiratory distress syndrome, and immunomodulation

   Författare :Joakim Johansson; Folke Sjöberg; Lennart Lindbom; Sven-Erik Ricksten; Linköpings universitet; []
   Nyckelord :ARDS; azurocidin; burn; CAP-37; critical care; granulocyte; HBP; histamine; intensive care; leucocyte; leukocyte; mediator; methylhistamine; MOF; oedema; neutrophil; permeability; PMN; trauma; vascular permeability;

   Sammanfattning : Background: Our innate immunesystem protects us from infections but, since its methods is not all specific for microorganisms, may also induce collateral damage.Severe physical injury often proved deadly throughout evolution. Such injuries may induce massive collateral damage. LÄS MER

5. 9. Subsets of Human Dendritic Cells and their Role in Allergy

   Författare :Kristina Lundberg; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergy; Dendritic cells; histamine; antibody mediated allergen-presentation; Dendritic cell subsets;

   Sammanfattning : The immune system has evolved to protect the human body against harmful invaders. At the same time, development of tolerance against self-derived and innocuous foreign antigens is of vital importance in order to avoid detrimental immune disorders. In allergic conditions, hypersensitivity is developed against harmless antigens, such as pollen. LÄS MER

7. 10. Effects of Motion Sickness on Human Thermoregulatory Mechanisms

   Författare :Gerard Nobel; Ola Eiken; Nigel A.S. Taylor; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motion Sickness; autonomic thermoregulation; behavioural thermoregulation; hypothermia; acetylcholine; histamine; Physiology; Fysiologi;

   Sammanfattning : The presented studies were performed to investigate the effects of motion sickness (MS) on human autonomic and behavioural thermoregulatory mechanisms during cold stress and in a thermoneutral environment. The roles of histaminergic and cholinergic neuron systems in autonomic thermoregulation and MS-dependent dysfunction of autonomic thermoregulation were studied using a histamine-receptor blocker, dimenhydrinate (DMH), and a muscarine-receptor blocker, scopolamine (Scop).
