  1. 21. Humoral immune responses to allergens in early childhood

    Författare :Kaja Julge; Örjan Strannegård; Sirje Velbri; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Sensitivity to eight standardized allergen extracts (Solu-Prick SQ, ALK, Hørsholm, Denmark) was assessed in 1580 schoolchildren. The prevalence of atopic sensitization among these 10-12-year-old children was 3--4 times lower in Estonia (8.1-14.3%) than in Sweden (24. LÄS MER

  3. 22. Environmental Factors in Relation to Asthma and Respiratory Symptoms among Schoolchildren in Sweden and Korea

    Författare :Jeong-Lim Kim; Gunilla Wieslander; Dan Norbäck; Lena Elfman; Nils Åberg; Uppsala universitet; []
    Nyckelord :Medical sciences; Allergen; allergy; asthma; dampness; diet; environment; formaldehyde; nitrogen dioxide; plasticizer; schoolchildren; ultrafine particles; MEDICIN OCH VÅRD;

    Sammanfattning : This thesis studied environmental factors in relation to asthma and respiratory symptoms among schoolchildren in two countries. In Sweden, 1014 pupils (5-14 year) in 8 schools participated. Wheeze was reported by 7.8%, current asthma by 5. LÄS MER

  4. 23. Indoor environment and recurrent wheezing in young children

    Författare :Gunnel Emenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Child; asthma; allergy; wheezing; air pollution; NO2; indoor air quality; building construction; ventilation system; indoor humidity; house dust mites; damp buildings; moisture; moulds; prospective studies; child;

    Sammanfattning : Recurrent wheezing is one of the most common causes of morbidity and hospitalisation among infants and young children in many westernised countries. Respiratory infections and exposure to tobacco smoke have been identified as important risk factors. The indoor environment is also clearly of importance since we spend most of our time indoors.

  5. 24. The role of mast cell proteases in allergic disease and apoptosis

    Författare :Ida Waern; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mast cells (MCs) are key effector cells in allergic reactions, through the release of a wide variety of granule-stored and de novo synthesized inflammatory mediators. The MC secretory granules contain exceedingly high levels of serglycin proteoglycan and the heparin-binding proteases chymase, tryptase and carboxypeptidase A. LÄS MER

  7. 25. Human eosinophils and their activation by allergens via danger signal receptors

    Författare :Elin Redvall; Göteborgs universitet; []
    Nyckelord :human eosinophils; danger signals; allergen; formyl peptide receptors; CCR3; chemotaxis; degranulation; free oxygen radicals; receptor desensitization;

    Sammanfattning : Human eosinophilic granulocytes are polymorphonuclear cells with a powerful arsenal of cytotoxic substances in their granules, which are mainly found in the gastrointestinal mucosa, and the respiratory and genitourinary tracts. Their physiological role is incompletely understood, although it is likely they protect the mucosal surfaces, perhaps by recognizing danger signals present on microorganisms or released from damaged tissue.
