    Description / Table of Contents: Zusammenfassung Die Geruchsunterschiede mehrererexo-Isocamphanylcyclohexanole werden durch den Vergleich der Molekülform erklärt. Mittels einer teilweisen Anpassung der molekularen Oberflächen werden die notwendigen strukturellen Bedingungen für den Sandelholzgeruch bestimmt.
    Notes: Summary The odour differences of variousexo-isocamphanylcyclohexanols are explained by molecular shape comparison. A partial matching of the molecular surfaces is used to evaluate necessary structural conditions for the Sandalwood scent.

    Notes: Abstract Regional cerebral glucose metabolism (rCMRGlc) and dopamine D2 receptor binding were measured in a 31-year-old, severely affected, untreated patient with Wilson's disease of 3 years' duration using positron emission tomography and18F-deoxyglucose and18F-methylspiperone ([18F]MSP), respectively. There was a severe reduction of striatal and extrastriatal rCMRGlc as well as of striatal [18F]MSP accumulation rate. After 1 year of treatment withd-penicillamine, striatal and extrastriatal rCMRGlc and striatal [18F]MSP accumulation rate reached almost normal levels. It is hypothesized that recovery of motor functions due to copper trapping therapy was associated with an increase in basal ganglia activity and a re-expression or upregulation of dopamine D2 receptors.

    Notes: Abstract Using positron emission tomography (PET), the regional cerebral metabolic rate of glucose consumption (rCMRGlc) was measured in 14 patients with Wilson's disease (WD) and 23 normal subjects. In WD patients, cerebellar, striatal and — to a lesser extent — cortical and thalamic rCMRGIc were significantly decreased compared with controls. Striatal rCMRGIc was significantly reduced in those 4 patients who had recently started decoppering therapy as compared with striatal rCMRGlc measured in those 10 patients with longer duration of medication. Caudate rCMRGlc correlated significantly with various signs of extrapyramidal dysfunction. Cerebellar, thalamic and cortical rCMRGlc correlated significantly with the severity of pyramidal signs. These data indicate that the PET measurement of rCMRGIc may be a useful tool to evaluate cerebral involvement in WD and to monitor the response to treatment.
