    Sammanfattning : The present studies were performed to elucidate several physiological and clinical questions of calcitonin (CT) and parathyroid hormone-related protein (PTHrP) such as: a) Does age influence the basal and calcium-stimulated levels and circulating molecular forms of CT in healthy females? b) Are osteoporotic patients lacking circulating monomeric CT? c) How is salmon CT (sCT) absorbed and cleared during treatment of diseases? d) Is there any effect of acute physical activity on circulating CT, PTH, PTHrP and bone metabolic markers? e) Is there an absorbance of PTHrP in milk by the neonate? and f) Are there any interactions between CT and PTHrP? In addition, by use of time-resolved dissociation and enhancement lanthanide fluorometry, the effort was put to develop two-site immunofluorometric assays (IFMA) for sCT and PTHrP as well as a quantitative competitive PCR (QC-PCR) for measuring PTHrP mRNA and use these methods in some of the investigations. Heterogeneity of CT forms in serum was disclosed after immunoextraction, fast protein liquid chromatography (FPLC) and radioimmunoassay (RIA) in healthy females and osteoporotic patients. LÄS MER
