    Description / Table of Contents: Summary In a family of Italian origin, we found four members with a considerable activity of creatine kinase inside their erythrocytes. All other clinical and hematological findings were normal. The enzyme anomaly seems to be inherited in the autosomal mode. The creatine kinase (CK) activity in freshly drawn blood was about 12 U/g Hb. The activity was higher in young red cells than in older ones. Studies with specific antibodies against human CK isoenzymes revealed the CK activity in Offprint requests to: Prof. Dr. H. Arnold (address see above) the probands' red cells to be due to about 90 % to the BB-isoenzyme normally found in brain and nerve tissue. The presence of CK in the erythrocytes does not seem to have any consequences for the energy metabolism of these cells. Creatine concentration was slightly elevated, but creatine phosphate could not be detected.
    Notes: Zusammenfassung Bei vier Angehörigen einer italienischen Familie fanden wir eine erhebliche Kreatinkinaseaktivität in den Erythrozyten. Sämtliche hämatologischen und klinischen Befunde unserer Probanden waren normal. Das abnorme Vorkommen der Kreatinkinase wird autosomal vererbt. In frisch entnommenem Blut hatte die Kreatinkinase eine Aktivität von etwa 12 U/g Hb. Die Aktivität war in jungen Erythrozyten höher als in älteren Zellen. Untersuchungen mit spezifischen Antikörpern gegen die menschlichen Kreatinkinase-(CK)Isoenzyme ergaben, daß die abnorme Kreatinkinase zu etwa 90 % dem BB-Isoenzym entspricht, das normalerweise in so hoher Konzentration nur im Gehirn- und Nervengewebe vorkommt. Die Gegenwart des Enzyms in den Erythrozyten der Probanden scheint keine Bedeutung für den Energiestoffwechsel der Zellen zu haben. Kreatin, das auch in normalen Erythrozyten vorkommt, ist auf etwa das Doppelte erhöht, während Kreatinphosphat genau wie in normalen Erythrozyten nicht nachweisbar ist.

    Description / Table of Contents: Summary Activity of creatine kinase isoenzyme MB in serum and variants of red cell acetylcholinesterase were determined in patients with Duchenne muscular dystrophy, in other forms of Dystrophy and in family members of Duchenne patients and healthy controls. Creatine kinase isoenzyme MB was observed only in all cases of DMD as well as variants of red cell acetylcholinesterase characterized by so-called inhibitor numbers. Carriers of Duchenne muscular dystrophy can be distinguished from Duchenne patients and healthy controls by estimation of Acetylcholinesterase variants.
    Notes: Zusammenfassung Die Aktivitäten der Creatinkinase und des Creatinkinase Isoenzyms MB im Serum sowie Varianten der Erythrozyten-Acetylcholinesterase wurden bei Patienten mit Muskeldystrophie Typ Duchenne (DMD) und anderen Formen sowie bei den Verwandten und gesunden Kontrollpersonen bestimmt. Nur bei Fällen von DMD konnten Creatinkinase-Isoenzyme MB wie auch Varianten der Acetylcholinesterase der Erythrozyten nachgewiesen werden.

    Description / Table of Contents: Summary We report the case of a 56-years old patient with clinical symptoms of an unresolved neuromuscular disease. Thelight microscopic studies of a muscle biopsy from the m. triceps shows the picture of a diffuse muscular atrophy. Byelectron microscopy, myelin-like degeneration zones with tubular-filamentous inclusions can be shown in the cytoplasma of the atrophic muscle cells. These filamentous structures correspond morphologically to the nucleocapside ofparamyxoviruses. These results lead, even without the proof of inflammatory cells, to the diagnosis of an “inclusion body” myositis also taking into account the clinical and electrophysiological findings.
    Notes: Zusammenfassung Es wird über einen 56jährigen Patienten mit den klinischen Symptomen einer unklaren neuromuskulären Erkrankung berichtet. Dielichtmikroskopische Untersuchung einer Muskelbiopsie aus dem m. triceps ergibt das Bild einer diffusen Muskelzellatrophie.Elektronenmikroskopisch werden im Cytoplasma der atropischen Muskelzellen myelinartige Degenerationsherde mit tubulär-filamentösen Einschlüssen nachgewiesen. Diese Filamentstrukturen entsprechen morphologisch dem Nucleocapsid von Paramyxoviren. Dieser Befund führt auch ohne den Nachweis interstitieller Entzündungszellen gemeinsam mit den klinischen und elektrophysiologischen Ergebnissen zur Diagnose einer „inclusion body myositis“.

    Notes: Abstract The nuclear polarization of an optically pumped3He target can be determined by optical methods if one makes some assumptions on the kinetics of the pumping process. Experiments and calculations have been carried out to examine whether these postulates are permissible. A good agreement between experiments and theory confirms the correctness of the assumptions and consequently justify the determination of the nuclear polarization by optical methods.
