  1. 21. Hypoxia and auto resuscitation in the neonatal rodent with special reference to the sympatho-adrenal system

    Författare :Shi-Zeng Yuan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adrenal medulla; apnea; asphyxia; autoresuscitation; catecholamines; SIDS;

    Sammanfattning : Preterm infants exhibit irregular breathing with frequent episodes of apnea, which may be associated with cyanosis and bradycardia. Perinatal asphyxia causes a considerable amount of morbidity and mortality that occurs during early life. Studies of mechanisms responsible for perinatal asphyxia are therefore very important.

  4. 23. Allergy to laboratory animals : risk factors for development of allergy and methods for measuring airborne rodent allergens

    Författare :Anne Renström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :laboratory animal allergy; atopy; IgE; methacholine provocation; aeroallergen measurement; ELISA; monoclonal antibody; Mus m 1; Rat n 1;

    Sammanfattning : Between 10-50% of workers exposed to laboratory animals, mainly rats or mice, develop laboratory animal allergy (LAA) with symptoms of rhinitis, conjuctivitis, asthma, or urticaria, and IgE against animal allergens. Symptoms often arise within the first years of animal work. Up to half of the symptomatic subjects develop asthma. LÄS MER

  5. 24. Microcirculation in native and transplanted rodent pancreatic islets with special reference to the influence of diabetes mellitus

    Författare :Per-Ola Carlsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic islets; islet microcirculation; microspheres; micropuncture technique; islet blood flow; islet capillary pressure; oxygen tension; transplanted islets; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The aim of the present work was to characterize the islet microcirculation in animal models of type 1 and type 2 diabetes, as well as in islets transplanted to diabetic or normoglycemic recipients. For this purpose, a microsphere technique was evaluated and applied for measurements of islet blood flow in mice. LÄS MER
