  1. 1. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics

    Författare :Trygve Sjöberg; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; arteries; veins; lymphatis; contraction; in vitro; in vivo; adrenergic receptors; noradrenaline; cirazoline; phenylephrine; clonidine; calcium antagonists; nifedipine; diltiazem; prostaglandins; thromboxane A2; U-46619; BM-13.505; indomethacin;

    Sammanfattning : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. LÄS MER

  3. 2. Ischemic Cell Death in the CNS - applications of a new in vitro model

    Författare :Tobias Cronberg; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; Neurology; astrocyte; stroke; adenosine; hyperglycaemia; glucose; free radicals; calcium; in vitro; brain ischemia; slice; neuropsychology; neurofysiologi; neurophysiology;

    Sammanfattning : Ischemic brain damage is a common cause of death and disability. A global ischemic insult is usually the result of a transient cardiac arrest while occlusion of cerebral blood vessels leads to focal ischemic lesions, commonly termed stroke. LÄS MER

  4. 3. Opioids regulate proliferation of neural progenitors. A study on the effects of opioids on adult rat hippocampal progenitors in vitro and in vivo

    Författare :Anders I. Persson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Opioid; brain; hippocampus; rat; neurogenesis; progenitor; stem cell; b-endorphin; calcium; MAPK;

    Sammanfattning : The opioid receptors were among the first pharmacologically described brain receptors. These opioid receptors have thereafter been shown to mediate effects on proliferation and differentiation in both the embryonal and adult central nervous system. LÄS MER

  5. 4. 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

  7. 5. On the mechanisms and physiological function of somatodendritic dopamine release in substantia nigra

    Författare :Filip Bergquist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium channels; dopamine release; microdialysis; rotarod; SNARE; striatum; substantia nigra;

    Sammanfattning : Somatodendritic release of neurotransmitters is a neuronal function that is poorly understood in comparison with the more abundant terminal release. This study aimed at characterising somatodendritic dopamine release in substantia nigra in terms of release mechanisms and possible physiological function in motor control. LÄS MER
