  1. 11. In vitro studies on cholecystokinin-induced inhibition of acid formation in gastric glands

    Författare :Per Bengtsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The design of methods useful for the preparation of viable glands and cells from the gastric mucosa allowed detailed studies on the mechanisms that regulate gastric acid secretion. The preparation of rabbit gastric glands was the first suitable method to be used and a number of important scientific contributions have been accomplished with this method. LÄS MER

  3. 12. Opioid-induced cholecystokinin release in the CNS-neurochemical mechanisms and effects of sciatic nerve lesion

    Författare :Henrik Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cholecystokinin (CCK) and opioid peptides have a similar distribution in the nervous system and CCK has been demonstrated to counteract opioid-induced analgesia at spinal and supraspinal level. An increased spinal release of CCK has been suggested to be a mechanism for the relative resistance to opioid analgesic drug in certain pain conditions following nerve lesions (i. LÄS MER

  4. 13. Experimental studies on the sources, pathways and targets for volume transmission in the rat brain

    Författare :Anders Jansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :volume transmission; extracellular space; monoamines; Dl D2 receptors; 5HT2A receptors; nitric oxide; interleukin-1ß; cholecystokinin; galanin;

    Sammanfattning : Volume transmission has been defined as the three-dimensional diffusion or convection of transmitters in the extracellular space (ECS) and cerebrospinal fluid (CSF) over a larger distance than the synaptic cleft. The regional localization of dopamine (DA) nerve terminals and dopamine Dl and D2 receptors in nucleus accumbens were studied in detail using double immuno-labelling. LÄS MER

  5. 14. Characterization of neuropeptide, monoamine, and amino acid release in the basal ganglia of the rat : neuronal dependence and reciprocal interactions

    Författare :Zhi-Bing You; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :amino acids cholecystokinin dopamine dynorphin microdialysis morphineneostriatum rat substantia nigra.;

    Sammanfattning : Functional interactions in the basal ganglia of rats were characterized with in vivomicrodialysis. The study was mainly focused on the dynorphin and cholecystokinin (CCK) systems. The extracellular levels of both dynorphin B and CCK were found in the pM range inthe neostriatum and substantia nigra under basal conditions. LÄS MER

  7. 15. Neuro-immune communication: role of the vagus nerve : an electrophysiological study

    Författare :Violeta Bucinskaite; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cholecystokinin; CCKA; CCKB; cytokines; IL-1[beta]; illness; nerve activity; NIDDM; OLETF; the vagus; vagotomy;

    Sammanfattning : Defence mechanisms involve close interactions between the nervous and immune systems following an immune challenge. The vagal pathways which modulate major visceral functions under normal conditions are also important neural pathways for the transmission of information on peripheral conditions to the CNS. LÄS MER
