    Description / Table of Contents: Zusammenfassung Bei 48 plötzlichen Kindstodesfällen und in einem Vergleichskollektiv (n=18) wurden in jeweils drei verschiedenen topographischen Regionen planimetrisch Innenumfang und Mediaquerschnittsflächen der Aa. vertebrales bestimmt. Unter Berücksichtigung eines experimentell ermittelten Meßfehlers fand sich in beiden untersuchten Gruppen in mehr als der Hälfte der Fälle ein gesicherter Seitenunterschied. Diese Seitenunterschiede waren zum Teil erheblich und lassen hämodynamische Konsequenzen erwarten. Es werden die Beziehungen zum plötzlichen Kindstod erörtert.
    Notes: Summary The internal circumference of the vertebral artery and the cross-sectional area of its tunica media were measured planimetrically at three different topographical sites in 48 cases of sudden infant death syndrome (SIDS) and 18 reference cases. Based on preliminary determination of the error of measurement, both groups studied showed significant differences between sides. As the degree of differences is often marked, impressive haemodynamic consequences can be expected. The findings are discussed with regard to SIDS.

    Notes: Summary Changes in the expression of glial fibrillary acidic protein by astrocytes in the primary visual cortex of adult albino rats were analyzed with immunohisto-chemistry after unilateral destruction of the dorsal lateral geniculate nucleus. An increase in number of glial fibrillary acidic protein-immunoreactive astrocytes could be detected in the visual cortex of the side ipsilateral to the lesion in the short-term survival group (7–11 days post lesion), but this increase was extremely reduced after a postlesional survival time of 150 days. The quantitation of the glial response by image analysis showed, that the initial increase was mainly localized in the cortical layers II–IV, where the geniculo-cortical input terminates. The transient nature of this process was revealed by the measurements in the long-term survival group, where differences between experimental and control sides were substantially reduced. We conclude, that the remote glial response in the visual cortex is transient and that its disappearance indicates the end of a postlesional adaptation period in the neuropil.
