    Notes: Summary In 1984 10,281 sera were collected in the FRG and examined for antibodies to HTLV-III (LAV) with an enzyme-linked immunosorbent assay and confirmative tests. Of the German AIDS patients 81% have antibodies. Individuals belonging to AIDS risk groups, homosexuals, haemophiliacs and i.v. drug abusers, have antibody frequencies between 25%–72%. The detection of HTLV-III antibodies in blood donours indicates that the virus is being transmitted by blood transfusions.

    Notes: Summary Samples of 96 polyvalent and virus-specific immunoglobulin batches commercially available in West-Germany were tested by enzyme-linked immunoassay and immunoblot for the presence of anti-HTLV-III antibodies. 37% of the polyvalent and 87% of the virus-specific batches were positive. It was concluded that these preparations are still safe and because of their reportedly low titer neutralizing antibodies possibly beneficial in certain cases, such as newborns of HTLV-III positive mothers or after accidental exposure to infectious material in clinics or laboratories.

    Description / Table of Contents: Zusammenfassung Bei 312 erkrankten Kindern im Alter bis zu 12 Jahren wurde die Aktivität der Isocitratdehydrogenase (ICDH) im Serum ermittelt, um deren mögliche diagnostische Bedeutung für die Pädiatrie festzustellen. Dem Krankengut wurde ein Normalkollektiv von 176 gesunden Kindern gegenübergestellt. Die Normalwerte der ICDH-Aktivität im Serum bei Neugeborenen liegen zwischen 1,88 und 8,76 mU mit einem Mittelwert von 4,8±2,2 mU; bei Kindern bis zu 12 Jahren zwischen 0 und 5,13 mU mit einem Mittelwert von 2,21±0,91 mU. In 80% der Fälle von akuter Virushepatitis zeigte die Serum-ICDH Aktivitätserhöhungen bis zu 59,6 mU/ml, wobei das Ausmaß der Erhöhungen der ICDH bei akuter Virushepatitis keinen sicheren Schluß auf Schwere und Prognose der Erkrankung zuläßt. Der diagnostische Wert der ICDH bei Erkrankungen im Kindesalter liegt vor allem in den akuten Krankheitsverläufen (akute Virusmyokarditis oder Virushepatitis). Im Liquor cerebrospinalis gesunder Kinder war keine Aktivität nachweisbar, im pathologischen Liquor fanden sich unterschiedliche Erhöhungen, die keinen differentialdiagnostischen Rückschluß erlaubten.
    Notes: Summary Serum isocitric dehydrogenase (S-ICD) was determined in 176 healthy children and 312 children with various diseases. In healthy children, the normal value lies at 2.2 mU with a standard deviation of ±0,9 mU. The average value is depending on the age of the patients. In 80% of all cases of acute virus hepatitis the S-ICD showed an increase in activity, but no strict correlation between the increase in activity and the prognosis of the individual case could be found in children suffering from mucoviscidosis, myatonia dystrophica, and progressiv muscular dystrophy. An activity of the S-ICD in the liquor cerebrospinalis is only measureable in cases of meningitis, where an increase can be demonstrated. The diagnostic value of the determination of the S-ICD in pediatrics is limited to the acute stadium of diseases, where high activity can be found.

    Description / Table of Contents: Zusammenfassung Bei gesunden und kranken Kindern wurden intraerythrocytäre Enzyme unter besonderer Berücksichtigung der ICDH und G-6-PDH gemessen. Die Normalwerte für die ICDH liegen zwischen 14,2 und 42,1 mE/109 Erythrocyten (Höchstwert!), die der G-6-PDH zwischen 240 und 388,3 mE/109 Erythrocyten. Bis auf die Blutgruppenunverträglichkeit konnte bei keiner von uns erfaßten Erkrankung eine signifikante Änderung der ICDH oder G-6-PDH festgestellt werden. Auf das unterschiedliche Verhalten der Enzyme in Neugeborenenerythrocyten und in jungen Erythrocyten Erwachsener wurde nochmals hingewiesen, ebenso auf eine Korrelation zwischen G-6-PDH und ICDH, die statistisch verifiziert wurde.
    Notes: Summary ICD and glucose-6-phosphate dehydrogenase (G-6-PDH) were determined in healthy children as well as in children with various diseases. In healthy children the normal value for the ICD lies between 14.2 and 42.1 mE/109 erythrocytes. For the G-6-PDH the normal values are between 130.1 and 388.3 mE/109 erythrocytes with an average of 240.8 mE/109 erythrocytes. The normal values are significantly wide spread, they are also depending on the age of the examined children. In our cases no significant decreases in the intraerythrocytic activity of the two enzymes could be stated in children with various diseases. Various enzymatic results show that the erythrocytes of newborns and young children are more different from those of adults than previously assumed.

    Description / Table of Contents: Zusammenfassung Bisher konzentrierten sich die Anstrengungen zur Entwicklung einer AIDS- Vakzine auf die Induktion neutralisierender Antikörper. Die glykolisierten HIV Hüllproteine exprimieren die neutralisierenden Epitope. Diese Hüllproteine konnten durch rekombinante DNA-Techniken in größerem Maßstab hergestellt werden, ihre Verwendung als Vakzine war jedoch wenig erfolgreich. Die spezifischen Epitope, an die neutralisierende Antikörper binden, konnten mittlerweile festgelegt werden. Das Hauptepitop ist hypervariabel, andere sind jedoch konserviert. Mit diesen Kenntnissen kann jetzt die zweite Generation experimenteller Vakzine auf der Basis von HIV Hüllproteinen hergestellt werden. In der Zwischenzeit ergaben entsprechende Untersuchungen im SIV Tiermodell, daß inaktiviertes Gesamtvirus als Immunogen durchaus geeignet ist, als wirksamer Impfstoff eingesetzt zu werden. Gegenwärtig werden verschiedene HIV Vakzineentwicklungen vor allem im SIV Tiermodell auf ihre Wirsamkeit genauer untersucht. Dem Ausgang dieser Untersuchungen kann mit vorsichtigem Optimismus entgegengesehen werden.
    Notes: Summary Until recently, much of the effort put into the development of an AIDS vaccine has focussed on the elicitation of a neutralizing antibody response. The viral target of neutralization, HIV envelope glycoprotein, has been produced in bulk through recombinant techniques, but has had little success as a vaccine. The specific epitopes to which neutralizing antibodies bind have been mapped, and although the major epitope is hypervariable, others are conserved. This allows the design of second generation vaccines. Meanwhile, vaccine studies in the SIV animal model simply using inactivated virus as immunogen have demonstrated that an effective vaccine is at least possible. A variety of HIV vaccine preparations are now under investigation and the outlook for the future is promising.

    Notes: Summary On account of the electrostatical forces between the ions and electrons in the interior of a star, the mean molecular weight µ should be given a higher value than is usually assumed. It is believed that a satisfactory theoretical calculation of μ has not yet been given, and that it does not seem to be possible. The determinations of the chemical composition of the stars are regarded as shaky, because they are based on the value of μ.

    Notes: [Auszug] Host animals show an immune response to the surface of cells infected with RNA tumour viruses. An element of this response is due to expression of viral structural antigens, but the major part is due to virus-induced cell-surface antigens (CSAs). This article compares the properties of CSAs of the ...
