    Description / Table of Contents: Zusammenfassung Klinische und histologische Befunde des Knochens bei einer 35jährigen Hausfrau mit membranöser Lipodystrophie (Nasu) oder lipomembranöser polycystischer Osteodysplasie (Hakola et al.) wurden beschrieben. Hauptsymptome der Patientin war progressive Demenz. Knochensymptome waren bis jetzt nicht bemerkt. Das Computertomogram des Gehirns zeigte Verkalkung der Basalganglien beiderseits. Multiple cystische Herde wurden auf dem Röntgenogramm der Beine dargestellt, und membrano-cystische Struktur wurde im Knochenmark des Talus mikroskopisch gefunden. Die chemische Analyse der Fettsäure des Talusknochenmarkes und Lysosomenzyme der weißen Blutkörperchen enthalten keine spezifischen Befunde. Mögliche Beziehung zwischen membranöser Lipodystrophie und Bindegewebserkrankungen wurde diskutiert.
    Notes: Summary The case is described of a 35-year-old housewife diagnosed as having membranous lipodystrophy (as described by Nasu et al. in 1970 and called lipomembranous polycystic osteodysplasia by Hakola in 1972). The main symptom of this patient was a slowly progressive dementia. Skeletal symptoms were not seen. The computerized tomogram of the brain showed calcification of bilateral basal ganglia and the plain roentgenograms of the bones revealed cystic radiolucent areas at the distal end of the bones of the patient's extremities. Histological examination of the curetted material from the right talus revealed a ‘membranocystic’ pattern. The fatty tissue curetted from the cyst of the talus and the lysosomal enzymes of the white blood cells were biochemically normal. A possible relationship between this disease entity and connective disorders is considered.

    Application of catheter-tip i.s.f.e.t. for continuousin vivo measurement (1980)

    Notes: Abstract A catheter-tip pH sensor was developed for possible clinical and biomedical application, using an ion-sensitive field-effect transistor (i.s.f.e.t.). Its signal drift in buffer solutions during continuous measurement was less than 3 mV in 24 h (equivalent to about 0·05 pH in 24 h). The electric insulation was perfect when soaked in buffer solutions for more than 3 months. A continuousin vivo pH measurement was successfully achieved in nonheparinised arterial blood of a japanese monkey. There was no significant sign of clot formation for 8 hours. It revealed quick responses to respiratory acidosis and alkalosis, and the observed pH values were in accordance with those confirmed by a blood pH analyser. Also, a catheter-tip pCO2 sensor was prepared, using the catheter-tip pH i.s.f.e.t. The response time was 2 min for a 90% change in CO2 tension. The muscle pCO2 monitoring tested with it indicated a similar result to those with medical mass spectrometer.
