    Notes: Summary The levels of plasma testosterone, testosterone-oestradiol binding globulin (TeBG) and total serum acid phosphatase (TSAP) following antiandrogenic hormone therapy were investigated in 17 patients with prostatic carcinoma. The low levels of plasma total and free testosterone induced by castration decreased further after diethylsitlboestrol diphosphate (DES-D) administration. Plasma TeBG binding capacity after castration was 118.9% of the pre-treatment level and increased to 193.9%, 204.0% and 212.7% at 1, 2 and 3 weeks after DES-D dosing. The in vitro binding of 3H-testosterone to TeBG was not influenced in the presence of DES-D or stilboestrol. Clinical response following the DES-D therapy was associated with a decrease in the levels of TSAP. A significantly inversed correlation was found between the decrease in TSAP and increase in TeBG at completion of DES-D therapy. These results suggest that the high binding capacity of TeBG lowers the biologically active fraction of testosterone and thus may produce clinical effects.

    Notes: Abstract Shear viscosity, shear stress and first normal-stress difference have been investigated for glass- and vinylon-fiber filled polyethylene melts over a wide range of shear rate by means of three kinds of instruments. The influence of fiber content and fiber properties on the rheological properties is discussed. The viscosity increases with increasing aspect ratio and fiber content, and the influence of these parameters on the flow properties is evident at low shear rates. The first normalstress difference increases more rapidly with increasing glass fiber content, especially at low shear stresses. The influence of vinylon fibers on the first normal stress-difference vs. shear-stress relationship is different from that of glass fibers.

    Dynamic flow properties of vinylon fibre and glass fiber reinforced polyethylene melts (1984)
    Springer
    Rheologica acta 23 (1984), S. 408-416 
    Details
    ISSN: 1435-1528
    Keywords: Fiber-filled polyethylene melt ; glass fiber ; vinylon fiber ; dynamic flow properties

    Topics: Chemistry and Pharmacology , Physics
    Notes: Abstract An experimental study of the dynamic shear flow properties of polyethylene melts filled with glass fibers and vinylon fibers was carried out and comparison with the steady shear flow properties was made. The effects of loading level and the characteristics of the fibers on the rheological properties of the fiber-filled systems is discussed. The rigidity and complex viscosity of the fiber-filled systems is sensitive not only to the quantity of fibers but also to their length, distribution and properties. The Cox-Merz empirical law for complex viscosity and steady shear viscosity, and Roscoe's empirical relation for estimating the normal-stress coefficients are both able to be applied to pure polymer melts but not to fiber-filled systems.
