  1. 16. On minor salivary gland secretion in children, adolescents and adults

    Författare :Mikael Sonesson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Det finns få studier om de små spottkörtlarna, men deras främsta funktion anses vara att skydda individen genom att utsöndra ett skyddande sekret som utgör en slags barriär mot främmande och sjukdomsframkallande substanser. Från observationer på vuxna är det känt att körtlarna producerar en rad antibakteriella ämnen, tillhörande det specifika och det ospecifika immunförsvaret. LÄS MER

  3. 17. Molecular structure and intracellular location of five RNA : associated proteins in the salivary glands of the dipteran Chironomus tentans

    Författare :Sun Xin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :hnRNPs; RNA-binding domains; shuttling proteins; non-shuttling proteins; nucleo-cytoplasmic transport; SR proteins;

    Sammanfattning : The structure and intracellular flow of specific RNA-associated proteins have been characterized in the salivary gland cells in the dipteran Chironomus tentans. These cells contain four polytene chromosomes (I-IV), two of which harbour a nucleolus. LÄS MER

  4. 18. Head and Neck Cancer : Factors Affecting Tumour Growth

    Författare :Kaarina Sundelin; Elisabeth Paulette-Hultcrantz; Karin Öllinger; Karin Roberg; Hans Gustafsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; Chemoradiotherapy; Tumour; Malignant salivary; Metallothionein; Neo-angiogenesis; Metastases; Cytokine tumour necrosis factor-alpha; hepatocyte growth factor; Oncology; Onkologi;

    Sammanfattning : Head and neck cancer is the fifth most common cancer worldwide with an estimated annual global incidence of over 500 000 cases. These malignant tumours develop in the mucosal linings of the upper respiratory tract or in the salivary glands. The most common sites are in the oral cavity and larynx. LÄS MER

  5. 19. Modulation of serous salivary gland function by the sympathetic nervous system : a biochemical and ultrastructural study with special reference to β-adrenoceptor subtypes

    Författare :Roger Henriksson; Umeå universitet; []
    Nyckelord :Rat parotid gland; guinea-pig submandibular gland; ß-adrenoceptor subtypes; sympathetic denervation; sympathetic superstimulation; amylase secretion; cyclic AMP; ultrastructural stereology;

    Sammanfattning : The aim of the present investigation was to study the influence of the sympathetic nervous system and of various adrenoceptor agents on enzyme secretion and morphology in rat parotid and guinea-pig submandibular glands. Biochemical methods were combined with electron microscopical techniques. LÄS MER

  7. 20. Studies on the prevalence of reduced salivary flow rate in relation to general health and dental caries, and effect of iron supplementation

    Författare :Håkan Flink; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Unstimulated whole saliva; stimulated whole saliva; resting saliva; xerostomia; dry mouth; hyposalivation; caries; remaining teeth; body mass index; iron deficiency; serum ferritin; circadian rhythm;

    Sammanfattning : Background: Reduced salivary flow is a condition that affects oral health. Its prevalence is unknown in young and middle-aged adults and there is no known treatment that permanently increases the salivary flow rate. Reduced salivary flow is related to dental caries, the most common oral disease. LÄS MER
