  1. 1. Prevention of Postoperative Duodenal Ileus by COX-2 Inhibition Improves Duodenal Function in Anaesthetised Rats

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : John Sedin; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; duodenum; motility; enteric nervous system; luminal alkalinisation; CFTR; VIP; luminal Cl-; fluid secretion; solute absorption; mucosal permeability; 51Cr-EDTA; luminal osmolality; luminal hypertonicity; glucose; mannitol; orange juice; parecoxib; hexamethonium; mecamylamine; Physiology; Fysiologi;

    Abstract : Abdominal surgery inhibits gastrointestinal motility, a phenomenon referred to as postoperative ileus. Since the postoperative ileus disturbs duodenal physiology it is important to minimize the side effects of this condition. READ MORE

  2. 2. Regulation of Duodenal Mucosal Barrier Function and Motility The Impact of Melatonin

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Sommansson; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 51Cr-EDTA; bicarbonate secretion; duodenum; enteric nervous system; enterochromaffin cell; ethanol; hexamethonium; in vivo; mecamylamine; motility; mucosal permeability; parecoxib; rat; Physiology; Fysiologi;

    Abstract : The duodenal mucosa is regularly exposed to acid, digestive enzymes and ingested noxious agents. It is thus critical to maintain a protective barrier to prevent the development of mucosal injury and inflammation, which are often observed in situations when barrier function is impaired.

  3. 3. Effects of nicotine on mesolimbocortical dopaminergic neurotransmission : A pharmacological study in the rat

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Magnus Nisell; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nicotine; dopamine; ventral tegmental area; accumbens; prefrontal cortex; c-fos; drug-dependence; sensitization; mecamylamine; D; receptors; SCH 23390;

    Abstract : Tobacco-smoking represents a form of drug addiction to nicotine (NlC) and thereinforcing and dependence-producing properties of NIC depend largely on centraldopamine (DA) neurons, located in the ventral tegmental area (VTA) and projectingmainly to the nucleus accumbens (NAc; mesolimbic DA system) and the medial prefrontalcortex (PFC; mesocortical DA system). Generally, the mesolimbic DA system plays apivotal role in the reinforcing effects of natural rewards as well as of drugs ofabuse. READ MORE

  4. 4. Neurobiological basis of the nicotine withdrawal reaction : an experimental analysis

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Bengt E. Hildebrand; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rat; nicotine; nicotine withdrawal; behavior; locomotor activity; microdialysis; intracerebral injections; mesolimbocortical; dopamine; ventral tegmental area; nucleus accumbens; amygdala; immediate-early genes; c-fos;

    Abstract : The mesolimbocortical dopamine (DA) system is pivotal for the mediation of the reinforcing effects of many dependence-producing drugs. It consists of cell bodies in the ventral tegmental area (VTA) that project to e.g. the nucleus accumbens (NAC), the central nucleus of amygdala (CNA) and the medial prefrontal cortex. READ MORE

  5. 5. Nicotinic mechanisms in ethanol reinforcement. A neurochemical and behavioral study

    University dissertation from Göteborg

    Author : Mia Ericson; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Both smoking and alcohol consumption are known to cause severe health problems and there is an extensive co-abuse of tobacco and ethanol. The reinforcing properties of drugs of abuse may involve the brain mesolimbic dopamine system, that originates in the ventral tegmental area (VTA) and projects mainly to the nucleus accumbens.
