    Description / Table of Contents: Zusammenfassung Ein Säugling mit Phenylketonurie erhielt unbeabsichtigt für insgesamt 29 Monate eine phenylalaninarme Diät mit hoher alimentärer Säurelast. Eine vorübergehende Wachstumsretardierung und die Entwicklung von Harnsteinen dürften direkte Folgen, eine Karies im Alter von 6 Jahren möglicherweise eine langfristige Konsequenz der chronischen Säurebelastung gewesen sein. Das Beispiel dieser Krankengeschichte zeigt, daß eine chronische alimentäre Säurebelastung ernsthafte klinische Folgen haben kann.
    Notes: Summary An infant with phenylketonuria unintentionally received a highly acidic low phenylalanine diet for 29 months. Temporary growth retardation and urolithiasis were observed, probably as direct effects of chronic acid loading. Caries at the age of 6 years may be a late consequence. This case report shows that chronic dietary acid load may cause serious side effects.

    Notes: Abstract In the human placenta, besides the fetal blood vessel system a second extravascular contractile system exists. It is localized in the chorionic plate and runs in a longitudinal direction and adjacent to fetal blood vessels into the stem villi, where it forms perivascular contractile sheaths. Characteristically, cells of the extravascular contractile system are extremely long and spindle-shaped and give rise to fine cell processes, by which they obviously contact each other or insert into the basement membrane of the trophoblast. They show immunoreactivity with desmin, vimentin, α-actin, myosin, nitric oxide synthase type I (brain form) and dipeptidyl peptidase IV. The ultrastructure suggests that cells of the extravascular contractile system are related to smooth muscle cells, including subpopulations with myofibroblastic features. In stem villi a few cells are nitric oxide synthase type I immunoreactive. These cells are thought to be specialized smooth-muscle-like cells of the extravascular contractile system or cells of the extravascular contractile system related to paraneurons that generate nitric oxide, which, in turn, may modulate the tone of perivascular contractile sheaths. The high dipeptidyl peptidase IV activity suggests that modulation of the extravascular contractile system may also occur by substance P.

    Notes: Abstract Muonic x-ray spectra from the high-T c superconductor YBa2Cu3O6.95 have been measured in the superconducting and normal states. No significant differences were found between the two spectra when comparing the intensities of 27 lines.
