    Keto-enol tautomeric equilibrium of acetylacetone in trifluoromethane near the critical temperature (1991)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The keto-enol tautomeric equilibrium of acetylacetone in trifluoromethane were studied at 300±0.5 K (1 K above the critical temperature) from 130 kg m−3 to 800 kg m−3 by using FT–NMR. No anomalous behavior near the critical point has been found within the experimental error. The equilibrium constant decreases rapidly in the low density region (〈200 kg m−3) and the decreasing rate reduces with increasing the density of solvent. The density dependence is interpreted by the hydrogen bonding between trifluoromethane and acetylacetone.

    Zymograms and histochemistry of non-specific esterase in the salivary glands (1969)
    Springer
    Histochemistry and cell biology 18 (1969), S. 302-313

    Topics: Biology , Medicine
    Notes: Summary Zymogramic analysis of esterase in the mouse, rat and guinea-pig salivary glands was undertaken and demonstrated species and organ specificities of esterase with electrophoretic method. Salivary glands esterase was classified into A, B and C types based on the electrophoretic mobility. Mouse submandibular gland had the most complicated pattern, while guinea-pig showed the simpliest patterns which was devoid of B type of esterase. Rat salivary glands exhibited rather regular patterns. Similar zymogram patterns were obtained with many kinds of ester compounds, that is simple and substituted naphthol esters and indoxyl derivatives. The tests of inhibition and activation for esterase activity was obtained. Histochemical properties applied to inhibitor test in the esterase zymogram patterns showed no marked differences between ducts and acini.

    Lower eyelid reconstruction preserving symmetry of bilateral palpebral fissure (1991)
    Springer
    European journal of plastic surgery 14 (1991), S. 137-138

    Notes: Summary A method for lower eyelid reconstruction is reported. The lower lid defect is reconstructed with a composite flap including skin and orbicularis oculi muscle from the ipsilateral upper eyelid. To cover the donor eyelid defect, a composite graft (skin and the orbicularis oculi muscle) is taken from the contralateral upper lid. The width of the graft is half of that of the flap so that the resulting contour of the bilateral palpebral fissures is symmetrical. The donor scar is invisible being placed in the natural lid fold. The color and texture match of the reconstructed lower lid is excellent. This is a simple technique which can be done as an outpatient.
