  1. 1. Intestinal IgA synthesis: Localization and requirements for IgA class switch recombination

    Författare :Peter Bergqvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgA; Intestine; Gut associated lymphoid tissue; class switch recombination; CD40; germ free;

    Sammanfattning : Production of IgA at mucosal surfaces is one of the most striking features of the mucosal immune system. Despite that IgA was first discovered in the 1950’s and secretory IgA described in gut secretions and breast milk in the mid 1960’s we still have limited information about the sites and exact requirements for IgA class switch recombination.

  3. 2. Influence of the microflora on gastrointestinal nitric oxide generation : studies in newborn infants and germ-free animals

    Författare :Tanja Sobko; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nitrite; nitrate; IBD; lactobacilli; probiotics; germ-free; SCFA; H 2; newborn infants;

    Sammanfattning : Interactions between intestinal bacteria and the host play an important role in physiological regulation of gut function and in development of various diseases. Nitric oxide (NO) exhibits a variety of biological actions in the gut including regulation of regional blood flow, gut motility, water and electrolyte transport and immunity. LÄS MER

  4. 3. Influence of probiotics and other external factors on intestinal biochemical microflora-associated characteristics : studies in vitro and in vivo in gnotobiotic mice and in pigs

    Författare :Maria E Cardona G; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gastrointestinal microflora germ-free mice; lactic acid bacteria; microflora- associated characteristics; piglets; probiotics.;

    Sammanfattning : The benefit of harboring a balanced intestinal microflora is well recognized. Therefore, in order to 'maintain or improve the intestinal flora, the use of microbial species as feed supplements, i.e. probiotics, has rapidly increased. LÄS MER

  5. 4. Influences of some exogenous factors on the gastrointestinal ecosystem

    Författare :Aina Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Intestinal ecosystem; Intestinal microflora; Germ-free life; MACs; Establishment; TPN; EN; Probiotics; Lactobacillus delbrueckii; Streptococcus thermophilus; Faecal enema;

    Sammanfattning : An intestinal ecosystem has three major actors, i.e., the macroorganism, the microflora and the environment. LÄS MER

  7. 5. Clinical, immunological and olfactory aspects of sinusitis and nasal polyposis : with special reference to patients with cystic fibrosis

    Författare :Gert Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal polyposis; sinusitis; cystic fibrosis; allergy; bacteria; in-patient; interleukin-8; muramidase; nasal lavage fluid; polymerase chain reaction; Pseudomonas aeruginosa; smell; olfaction; anosmia; hyposmia; olfactory threshold test; identification smell test; germ-free animal; T-cell receptor; normal microbiota.;

    Sammanfattning : The otorhinolaryngological approach to the problem concerning rhinosinusitis and nasal polyposis in the recessive genetic disorder of cystic fibrosis (CF) has been developed based on data from international studies. Opinions differ on how to treat the otolaryngological manifestations of CF (sinusitis, nasal polyps and hyposmia). LÄS MER
