  1. 16. The kallikrein-kinin system in primary hypertension : dynamics of circulating components of the kallikrein-kinin system in relation to the renin-angiotensin-aldosterone system

    Författare :K. Peter Öhman; Linköpings universitet; []
    Nyckelord :aldosterone; angiotensin Il; blood pressure; human; prekallikrein; renin; tissue kallikrein; MEDICINE; MEDICIN;

    Sammanfattning : Kinins are potent vasodilatory and blood pressure lowering peptides, with additional effects on renal handling of electrolytes and water. The kallikrein-kinin system consists of two separate entities, one confined to the circulation and the other to both tissues and the circulation. LÄS MER

  3. 17. Analysis of Angiographies in Human Healthy Eyes and in Open-angle Glaucoma : Retinal Mean Transit Time and Optic Nerve Head Circulation

    Författare :Gunilla Bjärnhall; Albert Alm; Göran Sperber; Selim Orgul; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Oftalmologi;

    Sammanfattning : Purpose of the studies was to develop a more robust technique to determine retinal mean transit time in healthy and in glaucoma eyes and to evaluate the circulation of the optic nerve head in glaucoma patients.The retinal mean transit time impulse-response method was evaluated in human healthy eyes and normal values and reproducibility were tested.

  4. 18. Galanin in the pituitary and in human circulation : clinical and experimental studies

    Författare :Eva Grenbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The neuropeptide galanin has important roles in the central and peripheral nervous systems where it affects memory, seizure activity, appetite and pain transmission. Galanin is also present in the endocrine system and one of its most prominent effects is to stimulate the release of growth hormone (GH). LÄS MER

  5. 19. Local Immune regulation in human pregnancy : with focus on decidual macrophages

    Författare :Charlotte Gustafsson Lidström; Christina Ekerfelt; Eva Sverremark-Ekström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; placenta; leukocyte; ELISPOT; Clinical immunology; Klinisk immunologi;

    Sammanfattning : During pregnancy, the woman carries a fetus partly foreign to her immune system, because of the expression of paternal antigens. Despite this, the fetus is normally tolerated and not rejected, as is often the case with organs in allogeneic transplantations. LÄS MER

  7. 20. Histamine receptors and neuropeptides in the cranial circulation

    Författare :Anders Ottosson; Rättsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; Human - arteries - CGRP - SP - mast cells; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The sensory neuropeptides substance P (SP) and calcitonin gene-related peptide (CGRP) are present in human cerebral, meningeal and temporal arteries, as are peptides associated with the sympathetic (neuropeptide Y, NPY) and parasympathetic (vasoactive intestinal peptide, VIP) nervous system. NPY is a vasoconstrictor in cerebral and meningeal arteries and potentiates noradrenaline (NA) as a vasoconstrictor in temporal arteries. LÄS MER
