  2. 1. Studies on Prostanoid Production in the Umbilicoplacental Circulation

    Author : Pia Saldeen; Malmö Reproduktionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gynaecology; Obstetrics; Umbilical; Thromboxane; Pulsatility Index; Prostacyclin; Pregnancy; Placenta; Peroxidation; Growth restriction; Endoperoxides; Endothelium; Doppler; Diabetes; sexualitet; reproduktion; andrologi; gynekologi; andrology; reproduction; sexuality; Obstetrik;

    Abstract : The fetoplacental circulation is a low pressure system with a high vascular prostacyclin to thromboxane (Pc/Tx)synthesis ratio. In intrauterin growth restriction (IUGR) and diabetes the prostanoid balance may be altered. READ MORE

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

    Author : Trygve Sjöberg; Thoraxkirurgi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Functional characterisation of receptors for cysteinyl leukotrienes in smooth muscle

    Author : Eva Wikström Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cysteinyl leukotrienes; leukotriene receptor; histamine; antigen; smooth muscle; lipoxin; thromboxane; Schultz-Dale reaction;

    Abstract : The cysteinyl leukotrienes (leukotriene C4, D4 and E4) have potent biological actions which significantly contribute to the airway obstruction in asthma. Several of these effects are blocked by drugs known as CysLT1-receptor antagonists, which have been introduced as new treatment for asthma. READ MORE

  7. 5. Studies on antibodies against phospholipids

    Author : Leopold Årfors; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Antiphospholipid syndrome; anticardiolipin antibodies; lupus anticoagulants; platelets; platelet activation; complement activation; endothelial cells; thromboxane; prostacyclin; acetylsalicylic acid.;

    Abstract : The main clinical features of the antiphospholipid syndrome (APLS) are arterial and venous thrombosis, repeated spontaneous abortions and thrombocytopenia. Diagnosed concomitant with an underlying disease the designation is secondary APLS; otherwise primary APLS. READ MORE
