  2. 21. Opioids and regulation of breathing

    Author : Åsa Österlund Modalen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Sameridine; partial - opioid agonist; local anesthetic; morphine; ventilation; respiratory depression; hypercarbia; hypoxia; frakefamide; peripheral -opioid agonist;

    Abstract : A most important challenge even in modern medicine is effective treatment of pain. Respiratory depression is the most feared side effect of analgesic treatment in the clinical situation. READ MORE

  4. 22. The human carotid body in sensing and signaling of oxygen and inflammation

    Author : Jessica Kåhlin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : carotid body;

    Abstract : Oxygen is essential for cell survival and global oxygenation is closely monitored in order to protect tissues from hypoxic damage. The carotid body is an important systemic oxygen sensor responding to hypoxia and a multitude of other blood borne stimuli, including inflammatory mediators. READ MORE

  5. 23. Regulation of cardiorespiratory homeostasis in adult and developing rat by catecholamines : effects of hypoxia

    Author : Julie Peyronnet; Karolinska Institutet; Karolinska Institutet; []
    Keywords : hypoxia; brainstem; catecholamines; chemoreflexe; ventilation; perinatal rat;

    Abstract : The aims of the present study were as follow 1) to characterise the neuroplasticity of sympathetic ganglia in the adult rat, after exposure to long-term hypoxia and/or axotomy of the superior cervical ganglion (SCG). The cellular distributions of TH (tyrosine hydroxylase, the rate-limiting enzyme in catecholamine biosynthesis) and VIP (vasointestinal peptide, which enhances the expression of TH) were examined.

  6. 24. Respiratory drive assessment : an evaluation of the breath-by-breath occlusion pressure method in man

    Author : Lars Gösta Hellström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A simplified concept of respiratory drive is to consider it as the integrated "output" from the CNS to the respiratory "pump" muscles. This drive is a result of a complex central respiratory pattern generation, and can in abnormal situations, e.g. of pathological or pharmacological origin, be altered. READ MORE

  7. 25. Novel aspects on osmolality and plasma sodium during pregnancy and labour

    Author : Vibeke Moen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This thesis was designed to study causes and effects of changes in plasma sodium and osmolality during pregnancy and labour. The physiological changes of early pregnancy include reduction in plasma sodium and osmolality, as well as increased ventilation with reduced arterial pCO2. These changes are usually considered due to progesterone. READ MORE
