    Interleukin-1 inhibits keratan sulfate production by rabbit chondrocytes: Possible role of prostaglandin E2 (1995)

    Notes: Abstract We investigated the importance of prostaglandin E2 (PGE2) release in interleukin-1 (IL-1)-induced inhibition of aggrecan synthesis by chondrocytes. Keratan sulfate (KS) production was measured in parallel with PGE2 release in chondrocytes. IL-1 inhibited KS production and stimulated PGE2 release. In the presence of PGE2, there was a dosedependent decrease in baseline KS production. Indomethacin and dexamethasone partially blocked the IL-1-induced PGE2 release while KS production recovered. Our results suggest that IL-1 inhibits KS production, in part, by stimulating the release of PGE2.

    Infrahyoid spread of deep neck abscess: anatomical consideration (1998)

    Notes: Abstract. The aim of this study was to determine the pathway of infrahyoid extension of the oropharyngeal abscess considering the anatomy of the fascial spaces by cross-sectional imaging. CT scans and MR images were retrospectively reviewed in ten patients with known infrahyoid extension of oropharyngeal abscesses (eight with acute tonsillitis, two with acute phlegmonous oropharyngitis). In seven of eight patients tonsillar abscesses descended along the deep cervical fascia converging on the hyoid bone and further accumulated in the anterior cervical space through which extension to the mediastinum took place in four patients. In seven patients the abscesses involved the retropharyngeal space at the infrahyoid neck. In two of these seven patients the abscesses directly extended down into the upper mediastinum through the retropharyngeal space. In one patients of the seven mediastinal spread of an abscess occurred through the posterior cervical space, not through the retropharyngeal space. Cross-sectional imaging is valuable in the evaluation of deep neck abscesses and the pathway of spread. The anterior cervical space in the infrahyoid neck is important for mediastinal extension of pharyngeal abscesses.

    Optical properties of impurity atoms in pressurized superfluid helium (1995)
    Springer
    The European physical journal 98 (1995), S. 387-390

    Notes: Abstract We report on the optical properties of alkali atoms (Cs and Rb) in the pressurized superfluid helium. We observed excitation and emission spectra at various pressures from the saturated vapor pressure to about 25 atm. The theoretical calculations on the basis of the atomic bubble model have also been worked out. The qualitative agreement between the theoretical and experimental results with respect to the peak shift, the linewidth, and their pressure dependence is achieved in the framework of the spherical atomic bubble model. TheD 2 excitation spectra with the double peaks are interpreted qualitatively in terms of the Jahn-Teller effect, indicating the existence of the nontotally symmetrical density distribution of the surrounding helium atoms.
