    Notes: Summary Bilateral Parkinsonism has been observed in a 60-year-old female with a chronic subdural intracranial haematoma. Scattered, poorly marginated, hypodense areas within the ipsilateral pallidus and putamen were evident on the preoperative CT scans. The rapid neurological improvement following the surgical drainage of the subdural clot and the evolution of the densitometric features of the nuclear lesions, which became clear-cut, though smaller, in the following months, suggest a cause-and-effect relation between the haematoma and the clinical symptomatology. To the best of our knowledge this is the first case in which anatomical lesions within the basal ganglia could be detected neuroradiologically.

    Description / Table of Contents: Zusammenfassung Sowohl in phasischen wie auch in tonischen Muskeln von Ratten, welche mit 20–25 Diazacholesterol behandelt wurden, wurden diskrete Strukturänderungen festgestellt: Änderungen der Umrisse der Einzelfasern, zahlreiche Fasern mit „Mottenfraß“, seltene Ringfasern. Histochemische Reaktionen für oxidative Enzyme im Extensor digitorum longus myotonischer Tiere zeigten außerdem häufig größere Gruppen von Typ-I-Fasern und Fasern vom Zwischentyp als bei normalen Kontrollen (Tendenz zum „Type-Grouping“). Quantitative Auswertung zeigte im Extensor digitorum longus und im Soleus myotonischer Ratten eine mäßige Hypotrophie der Typ-I-und Typ-II-Fasern mit einer Zunahme der Anzahl der Fasern vom Typ I und vom Typ III im Extensor digitorum longus und einer signifikanten Abnahme des nicht dominanten Fasertypus im Soleus. Die Befunde werden besonders im Hinblick auf eine neurogen vermittelte oder unmittelbare Wirkung der Substanz auf die Muskelfaser diskutiert.
    Notes: Summary In both fast and slow muscles of rats treated with 20–25 diazacholesterol there were qualitative alterations, such as changes of fiber outlines, numerous moth-eaten fibers and rare ring fibers. In addition there were generally larger groups of Type I and intermediate fibers than in normal controls (“type-grouping” tendency) in the preparations for oxidative enzymes in the extensor digitorum longus (EDL) of myotonic animals. Quantitative evaluations of EDL and soleus of myotonic rats revealed moderate hypotrophy of Type I and Type II fibers with an increase in the number of Type I and of Type III fibers in the EDL and a significant decrease of the nondominant fibers in the soleus muscle. The data are discussed in the light of a neurally mediated and/or direct action of the drug on the muscle fiber.
