    Notes: Abstract Theg-factor of the 364 keV state of184W was measured by the time integral angular correlation method using the high hyperfine fields at the tungsten nucleus in iron. The same experiment was performed with the 111 keV state giving the ratiog(364 keV)/g(111 keV)=1.02(14). Using this ratiog(364 keV-level)=0.286(35) was deduced. For the hyperfine fields of W in Fe, W in Co and W in Ni at 300 K −610(35) kG, − 358(23) kG and −80(3) kG respective have been determined.

    Notes: Abstract Time differentialγγ-angular correlation measurements have been performed to determine the electric interaction of the 2.3 MeVI=5− state of120Sn in different polycristalline antimony compounds. A calibration of the field gradient was achieved by Mößbauerexperiments with the 23.8 keVI=3/2+ state in119Sn using identical sources. From the ratio of the measured electric interactions the ratio of the quadrupole moments is deduced as: $$\left| {\frac{{Q(2.3{\mathbf{ }}MeV level,{\mathbf{ }}I = 5^ - ,^{120} Sn)}}{{Q(2.8{\mathbf{ }}keV level,{\mathbf{ }}I = {3 \mathord{\left/ {\vphantom {3 2}} \right. \kern-\nulldelimiterspace} 2}^ + ,^{119} Sn)}}} \right| = 2.86(15)$$ . Using 0.06 (2) b for the quadrupole moment of the 23.8 keV level in119Sn one gets for the quadrupole moment of the 2.3 MeV level in120Sn ¦Q(2.3 MeV level,I=5−,120Sn)¦=0.021 (8) b.

    Notes: Summary The cell content of a CSF sample of a patient with mumps meningoencephalitis was divided into 4 portions and cultured in vitro. The first two cultures were stained 24 hrs later with fluorescein conjugated sera by the indirect method. The cells brought together with the serum containing antibodies against mumps virus showed a bright yellowish fluorescence; the controls were free. The diagnosis of mumps meningoencephalitis could be confirmed by serologic methods and by virus isolation. The two remaining cultures were stained 2 weeks later in the same way. A monolayer of epithelial cells had grown out. By fluorescence it could be demonstrated that these cells still contained large amounts of virus material.

    Description / Table of Contents: Zusammenfassung Ein atypischer Fall von myatrophischer Lateralsklerose wurde beschrieben, dessen Besonderheit auf einer Frühmanifestation, auf einer länger dauernden Asymmetrie der Initialsymptome, auf dem Fehlen einer bulbären Symptomatik bei sonst sehr fortgeschrittener Symptomatik, auf einem ungewöhnlich langen Verlauf und auf konstanten Zeichen einer entzündlichen Reaktion im Liquor beruht. Die konstante Liquor-Pleocytose war Anlaß, ausgedehnte virologische Untersuchungen einzuleiten, die im Versuch einer Virusisolierung gipfelten. Es wurde schließlich aus dem Liquor ein Virus isoliert, welches dem TbE-Komplex der Arbovirus-Gruppe B (tick-borne Flaviviren) zugehört. Etwa 70% einer Gruppe von 19 ALS-Patienten aus Hamburg hatten mit diesem Virus offenbar Kontakt. Das Antikörpermuster des Falles ermöglichte eine Erklärung seiner Besonderheiten.
    Notes: Summary An atypical case of amyotrophic lateral sclerosis (ALS) is described, characterized by early manifestation, a long lasting course with asymmetry of the lesions, absence of bulbar symptoms in the presence of an otherwise very advanced symptomatology, and constant signs of an inflammatory reaction in the CSF which was the reason to initiate extensive virological studies, including procedures for virus isolation. A virus, belonging to the TbE complex of arbovirus group B (tick-borne flaviviruses), was finally isolated from the CSF. About 70% of the ALS cases in Hamburg/W. Germany, examined for antibodies, appearently had contact with this virus. The antibody pattern found made it possible to explain this exceptional case.

    Description / Table of Contents: Zusammenfassung Aus dem Liquor eines Patienten mit mehrjähriger amyotropher Lateralsklerose, aber mit langdauernder Pleozytose, wurde ein Virus isoliert und durch Serienblindpassagen an Mäusebabys adaptiert. Es gehört zum sog. TbE-Komplex der Togavirus-Gruppe B. Gehirnhomogenat von Babymäusen der 13. Passage wurde auf Mäuse, Hamster und Cynomolgus-Affen verimpft. Bei den Hamstern entwickelten sich nach subkutaner Impfung Abmagerung und Parese der Hinterbeine. Histologisch fanden sich bei mehreren Tieren petechiale Blutungen und Zelluntergänge mit entzündlicher Reaktion in der grauen Substanz. Versuche mit wiederholten Impfungen von Hamstern mit verschiedenen Flavivirusstämmen in hoher Verdünnung sprechen dafür, daß sich bei dieser Versuchsanordnung Krankheitsbilder nach Art der Slow-Virus-Erkrankungen entwickeln mit fehlender enzephalitischer Reaktion und vorwiegendem Zelluntergang in Vorderhornzellen mit nur geringer entzündlicher Komponente. Intracerebrale Verimpfung von Schu-Virus erzeugte bei Cynomolgus-Affen eine stürmische Meningoencephalitis mit epileptischen Erscheinungen, Ataxie, spastischen oder schlaffen Lähmungen. Nach subkutaner Applikation des Virus kam es zur langsamen Ausbreitung der Infektion entlang des peripheren Nerven über die vorderen Wurzeln ins Rückenmark mit Untergang der motorischen Vorderhornzellen. Schließlich wurde auch das Gehirn erreicht. Die in den Versuchstieren gefundenen histologischen Läsionen lassen den Schluß zu, daß der Patient, aus dessen Liquor das Virus isoliert wurde, an den Folgen der Infektion mit diesem Virus erkrankt war. Daraus ergibt sich die Schlußfolgerung, daß zumindest ein Teil der als amyotrophe Lateralsklerose diagnostizierten Fälle ihre Erkrankung einer Arbovirusinfektion verdanken.
    Notes: Summary A virus isolated from the CSF of a patient who had amyotrophic lateral sclerosis for 7 years, and prolonged pleocytosis in the CSF, was adapted to suckling mouse brain by subsequent serial blind passages. This Schu virus belongs to the tick-borne encephalitis complex of the genus Flavivirus (Togaviridae). Suckling mouse brain homogenate of the 13th passage was used for transmission experiments in various species of laboratory animals. Golden hamsters infected subcutaneously fell ill after a number of months, lost weight, and had paresis of the legs. Histologically they had petechial hemorrhages in different parts of the CNS and inflammatory changes in the gray substance of the spinal cord. Pilot studies with repeated inoculations of small doses of different flavivirus strains suggest a course of the disease in experimental animals which resembles slow-virus infections insofar as no encephalitis is produced and degenerative changes of the anterior horn cells prevail over inflammatory signs in the spinal cord. After intracerebral application of Schu virus, cynomolgus monkeys developed the typical lesions of togavirus panencephalitis with epileptic seizures, ataxia, and paresis. After subcutaneous application, the virus seems to spread along peripheral nerves to anterior spinal roots and spinal cord, where mainly motor neurons of the anterior horn are damaged, and from there to the brain. The histological findings are such that one may assume the disease of the patient was due to the infection with the virus isolated from his CSF. Therefore, the hypothesis may be advanced that at least some of the cases diagnosed as amyotrophic lateral sclerosis are due to a togavirus infection.
