The synthesis of DNA was studied in the proximal tibial growth plate of 25-day-old healthy NMRI mice by using the thymidine analog bromodeoxyuridine (BrdUrd), which is incorporated into cells in the S-phase. Such cells were found only in the upper three fifths of the morphologically defined proliferating zone. This zone was therefore subdivided into a(More)
Sections from the nasal cavity of 12-day-old Swiss albino mice (NMRI strain) were subjected to lectin histochemistry. A panel of biotinylated lectins (Con A, WGA, s-WGA, PNA, SBA, DBA and UEA I) and a horseradish peroxidase-conjugated lectin (GSA II) showed marked differences in binding to the respiratory and the neuroepithelial cells. SBA (affinity for(More)
An immunocytochemical battery comprising 9 antibodies specifically distinguishes 80% of the epithelial malignant mesotheliomas from adenocarcinomas. The discriminatory power of antibodies to calretinin was tested together with this battery to determine whether the performance thereby could be improved. The study comprises 119 mesotheliomas of epithelial or(More)
We studied kinetics in the epiphyseal cartilage of the brachymorphic (bm/bm) mouse, combining morphometry and labeling with halogenated nucleotides. The defective synthesis of the sulfate donor PAPS in these homozygous mutants is evident in tissues with a large production of glycosaminoglycans; these compounds become undersulfated. Compared with their(More)
Syndecans are transmembrane proteoglycans implicated in the regulation of cell growth and differentiation, by interacting with growth factors. Although syndecans play a major role in regulating cell morphology, little is known about their subcellular distribution and in vivo association with the cytoskeleton. To address this question, we investigated the(More)
The effect of orally administered immunoglobulin (IgAbulin) on chronic non-specific diarrhoea of infancy was studied in seven children, median age 26 (21-36) months and duration of diarrhoea 32 (18-84) weeks. Routine laboratory tests for malabsorption and small bowel biopsies were taken in all children before and after 3 weeks of IgAbulin treatment. The(More)
A battery of immunocytochemical analyses, previously established to distinguish between malignant mesothelioma and metastatic adenocarcinoma, was extended by analysing the same cases with three other commercially available antibodies. Altogether, 11 antibodies were studied in mesotheliomas diagnosed by other means, using 14 different immunocytochemical(More)
BACKGROUND/AIMS In previous studies we have shown that variations in the properties of the stratum corneum are reflected by alterations in electrical impedance. The aim of this study was to explore the ability of the electrical impedance technique to detect changes in the lipid content of the stratum corneum, and to compare It with the other non-invasive(More)
Malignant mesotheliomas show a highly variable aggressiveness, but it is difficult to predict the outcome in the individual case at the time of diagnosis. Glutathione S-transferases are detoxification enzymes that have been correlated with the prognosis in some tumours. We have therefore assessed the value of GST expression as a prognostic parameter in(More)
