    Tamm-Horsfall glycoprotein in streptozotocin diabetic rats: a study of kidney in situ hybridization, immunohistochemistry, and urinary excretion (1995)

    Notes: Summary Tamm-Horsfall glycoprotein, present only in the kidney thick ascending limb of Henle's loop, was studied here in streptozotocin diabetic rats. Tamm-Horsfall glycoprotein mRNA in situ hybridization was performed on snap-frozen left kidneys; the right kidneys were perfusion-fixed with 4% paraformaldehyde and embedded either in paraffin, for Tamm-Horsfall glycoprotein immunohistochemistry, or in Epon for stereologic measurements. The length of the thick ascending limb of Henle's loop and the amount of glycogen were measured and the ultrastructure of the cells was evaluated. Urinary excretion of Tamm-Horsfall glycoprotein, calcium, magnesium and albumin was measured. After 10 and 50 days' duration of diabetes, kidney weight increased 20 and 41%, respectively and the length of the thick ascending limb of Henle's loop increased 28 and 56%, respectively, compared with controls. Substantial glycogen accumulations were present in the thick ascending limb of Henle's loop, and electron microscopy revealed a significant decrease in organelles and basolateral membranes. After 10 and 50 days' duration of diabetes, in situ hybridization of Tamm-Horsfall glycoprotein mRNA revealed a fourfold decrease, and the immunostaining for Tamm-Horsfall glycoprotein showed a threefold decrease as measured by densitometry. However, urinary Tamm-Horsfall glycoprotein excretion rate was increased fivefold and urinary concentration about twofold. Urinary calcium excretion increased threefold and magnesium twofold, but urinary albumin excretion was not significantly increased. The increased amount of Tamm-Horsfall glycoprotein, calcium and magnesium in the urine in diabetes occurs here concomitant with severe cellular damage in the thick ascending limb of Henle's loop.

    Ecology of benthic and epiphytic nematodes in brackish waters (1984)
    Springer
    Hydrobiologia 108 (1984), S. 201-217

    Notes: Abstract Abundances of benthic nematodes from shallow waters in Tvärminne, Finland and in Ringkøbing Fjord, Denmark averaged 1.2–1.5 106 individuals m−2. Less than 20 species were found. More than 80% of the individuals were made up by Anoplostoma viviparum, Chromadorita fennica, Axonolaimus spinosus, Daptonema trabeculosum and Sabatieria pulchra. S. pulchra is designated as an anoxybiotic species and is attracted to the root tips of young Potamogeton perfoliatus, whilst A. viviparum and C. fennica are oxybiotic species. Abundance of epiphytic nematodes extracted from submerged macrophytes in the Cladophora-Pilayella belt in the outer archipelago of the Finnish archipelago (July 1978) was estimated to reach 5 · 106 individuals m−2, equivalent to a biomass of 1.2 g org. C m−2. Abundance and biomass are smaller in the Potamogeton meadows in the inner archipelago, in littoral algal vegetation of the sea zone, and on sublittoral vegetation. Epiphytic nematode species composition is influenced by salinity and food availability and not by physiognomic types or silt contents of the vegetation in the Baltic Sea, European estuaries and lakes. Dominant species are: Chromadorina bioculata, Punctodora ratzeburgensis, Chromadorita tenuis, Adoncholaimus thalassophygas, Theristus acer, Monhystera parva, M. aff. filiformis and Chromadora aff. nudicapitata. A theory is proposed to explain observed seasonal changes in the species composition of epiphytic and benthic nematodes. During winter months, the submerged vegetation is mostly destroyed, being found as detritus on the sea bottom. Sampling benthic nematodes during winter thus includes epiphytic species living in the detritus. In spring the epiphytic nematodes detect the newly growing vegetation, leave the sea bottom, colonize the submerged vegetation and spend their life there.
