    Description / Table of Contents: Summary Glucocorticoids given to rabbits treated with a N-acetyl-p-aminophenol-load in contrary to sugars are not able to enhance glucuronide formation within the first three hours after application. The intravenous gift of prednisolone esters in high doses rather resulted in a decrease of glucuronide synthesis, which could be explained by known early effects of corticoids on metabolism. Furthermore there was an increased retention of the already formed glucuronides under the influence of the glucocorticoids. The conjugation of glucocorticoids themselves with glucuronic acid is of no importance in quantitative respects, so that competition with other aglycons is not worth mentioning.
    Notes: Zusammenfassung Es wird in Versuchen am Kaninchen gezeigt, daß im Gegensatz zu der schnell einsetzenden Wirkung von Hexosen auf die Glucuronidsynthese Glucocorticoide innerhalb der ersten 3 Std noch zu keiner Beschleunigung der mit N-acetyl-p-aminophenol angeregten Glucuronidbildung führten. Die in hoher Dosis intravenös applizierten Prednisolonester bewirkten eher einen Rückgang der Bildung von gepaarten Glucuronsäuren, was auf Grund der initialen Wirkung der Corticoide auf den Stoffwechsel erklärlich wäre. Zudem wurden die gebildeten Glucuronide unter dem Einfluß der Glucocorticoide verstärkt retiniert. Die eigene Konjugation der Glucocorticoide mit Glucuronsäure ist quantitativ unbedeutend, so daß eine nennenswerte Konkurrenz mit anderen Glucuronsäurepaarlingen um das entgiftende Enzymsystem nicht wahrscheinlich ist.

    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.

    Description / Table of Contents: Summary The reliability of a resin131I-triiodothyronine-in vitro-test (131I-T3-test) was statistically evaluated by test results of 1198 patients with known thyroid function. The131I-T3-test results were significantly higher in euthyroid females than in euthyroid males; there is also a significant decrease with age in females. But all these differences are so small, that they are of no practical value using a separated normal range for the different age or sex groups. A pretreatment with a thyroid-specific pharmaceutical don't alter the test result; the131I-T3-test represents the momentary functional state of the gland. Patients with “hypophysär kompensierte Hyperplasie” (iodine deficient goiter) are lying between the 2s-borderlines of the euthyroid subjects. Therefore it was possible to combine this two groups to one with “normal thyroid function”, without changing the normal range. By this means, 95,5% subjects with “normal thyroid function”, 90% of hyperthyroid patients and 86% of hypothyroid patients are correctly diagnosed by the131I-T3-Test alone. For the three function groups together the reliability of this test is 94,4%. Combinating the131I-T3-test-results with a point grading system, adding up the most important clinical symptoms for hyperthyroidism the overall reliability for euthyreoidism and hyperthyroidism becomes 99,5%. This reliability is limited, if there is a discrepancy between the results of the two methods or if a nodular goiter exists. In all these cases further studies with radionuclids are necessary.
    Notes: Zusammenfassung Die Treffsicherheit des131J-Trijodthyronin-in vitro-Tests (131J-T3-Test) mit einem Ionenaustauscherharz wurde anhand der Testergebnisse von 1194 Patienten statistisch untersucht, deren Schilddrüsenfunktionslage eindeutig abgeklärt war. Obwohl Männer durchschnittlich signifikant höhere131J-T3-Testwerte als Frauen aufweisen und bei den Frauen das Testergebnis signifikant mit dem Alter absinkt, sind diese Unterschiede so gering, daß für beide Geschlechter und unabhängig vom Alter ein einheitlicher Normalbereich vorgeschlagen wird. Eine medikamentöse schilddrüsenspezifische Vorbehandlung stört nicht, da der131J-T3-Test den bestehenden Funktionszustand der Drüse angibt. Die hypophysär kompensierte Hyperplasie ordnet sich so gut in den Euthyreosebereich ein, daß die beiden Gruppen, ohne Änderung der 2s-Bereichsgrenzen der Euthyreose, zu einer Gruppe „normale Schilddrüsenfunktion“ vereinigt werden konnten. 95,5% der Patienten mit normaler Schilddrüsenfunktion, 90% aller Hyperthyreosen und 86% aller Hypothyreosen werden bei dieser Bereichseinteilung richtig diagnostiziert. Die Treffsicherheit für die drei Funktionsgruppen beträgt insgesamt 94,9%. Durch Kombination des131J-T3-Tests mit einem Punktsystem, das die klinischen Merkmale bewertet, erhöht sich die Treffsicherheit für die richtige Diagnose der Hyperthyreose und Euthyreose auf etwa 99,5%. Diese Treffsicherheit gilt allerdings nur unter der Einschränkung, daß zur weiteren Abklärung eine ausführliche nuclearmedizinische Schilddrüsenuntersuchung durchgeführt wird, wenn sich die Ergebnisse beider Untersuchungsmethoden widersprechen oder falls ein Knoten zu tasten ist.

    Notes: Summary The study provides information on the epidemiology of HTLV-III infection and the lymphadenopathy syndrome (LAP) in 374 German homosexual men. Sexual contacts in the USA and rectal enemas before receptive anal intercourse are the main risk factors associated with virus transmission. HTLV-III seropositivity is significantly correlated with LAP. Prominent clinical signs are infreqquent. Immunological and haematological abnormalities are prevalent, and the retrovirus infection is frequently associated with serological markers of other viruses (hepatitis B, herpes group viruses). Lymphadenopathy as a manifestation of HTLV-III infection is discussed within the context of AIDS-related disorders.

    Notes: Abstract Sera from homosexuals and hemophiliacs in Germany were examined for antibodies to human T-lymphotropic retrovirus type III (HTLV-III) by an enzyme-linked immunosorbent assay (ELISA) against purified virus. ELISA positive sera were used to search by immunoprecipitation for HTLV-III related antigens in a persistently infected human T-cell line. A glycopolypeptide with a mol. wt. of 100 000 was regularly recognized by all positive sera. In analogy to glycosylation and high antigenicity of envelope polypeptides of other mammalian retroviruses, gp100 seemed to be related to the env gen. Two polypeptides with mol. wts. of 24 000 and 22 000 probably representing viral core polypeptides were additionally detected by sera with high ELISA titers.

    Notes: Abstract The efficiency was examined of immunization with feline leukemia virus glycoprotein complexes (gp85 rosettes) to protect cats against tumors induced by feline sarcoma virus (FeSV). The glycoprotein was isolated from feline leukemia virus (FeLV). Young cats were vaccinated with the purified viral glycoprotein and challenged with FeSV (FeLV). FeLV gp85 antibody levels were measured by enzyme-linked immunosorbent assay and tumor volumes were determined. In immunized animals tumor development was reduced. Gp85 antibody levels before challenge were correlated inversely with tumor size (r 2=0.79). This method appears to be suitable for fast and efficient testing of future FeLV vaccines.

    Description / Table of Contents: Zusammenfassung Die Gefüge von Pyrrhotinerzen von vier Lagerstätten wurden mit einem Röntgentexturgoniometer untersucht. Alle Proben zeigen eine Einregelung von (0001) ± parallel zur Ebene der Lagigkeit (s) der Erze. Die Gefügediagramme der (10 $$\bar 1$$ 2)-, (11 $$\bar 2$$ 0)- und (10 $$\bar 1$$ 0)-Reflexe von drei Fundpunkten haben orthorhombische Symmetrie. Die gleichen Diagramme der vierten Lagerstätte sind hexagonal. Die orthorhombischen Gefüge werden durch eine Deformation mit einfacher Scherung erklärt. Mit Hilfe eines Rechenprogrammes wurden entsprechende synthetische Gefügediagramme erzeugt. Ihre Ähnlichkeit mit der Mehrzahl der natürlichen Texturen macht das angenommene Modell wahrscheinlich. Auch kann geschlossen werden, daß die Proben — ausgenommen diejenigen mit nicht hinreichend deutbarer hexagonaler Symmetrie — durch eine Scherverformung entstanden sind. Gelegentlich scheint es möglich, durch Gefügeuntersuchungen an Erzen Rückschlüsse auf die tektonische Geschichte der Lagerstätte bzw. auf deren Beanspruchung zu ziehen.
    Notes: Abstract The fabrics of pyrrhotite ores from four deposits are determined by means of an X-ray texture goniometer. All specimens show (0001) ± parallel to the plane of schistosity (s) of the ores. The pole figures of the (10 $$\bar 1$$ 2)-, (11 $$\bar 2$$ 0)-, and (10 $$\bar 1$$ 0)-reflections from samples of three localities are of orthorhombic symmetry. The same pole figures from the fourth deposit show hexagonal symmetry. The fabrics of pyrrhotite with orthorhombic symmetry are explained assuming a model with a deformation by simple shear. Synthetic diagrams are plotted using a program which simulates the conditions of this model. The synthetic diagrams are in good agreement with most of the measured ones, and this argues for the validity of the suggested model on the one hand and on the other hand confirms that these pyrrhotite fabrics may have been formed by simple shear. The fabrics with hexagonal symmetry seem to be produced by a quite different mechanism. In some cases one may infer from the results of the fabric analysis of ores to the tectonical history and the mode of deformation of the ore deposit.

    Notes: Abstract Certain recently developed antidotes of the bispyridinium type, commonly called “H-oximes” (HGG 12, 21, 42, 52, 65, 70, 89, and HGG 90) have been investigated as to their effects on muscarinic and nicotinic acetylcholine receptors. These compounds clearly discriminate between these two types of receptors being more potent inhibitors of the muscarinic receptor with inhibitory constants in the micromole range. (The corresponding values for the nicotinic receptor are in the range of 0.1 mM.) However, the inhibitory potency in the binding assay does not correlate with the ED50 values obtained against soman in mice. The site of antidotal action therefore appears not to be the nicotinic acetylcholine receptor. Binding to the muscarinic receptors may partially contribute to the effects against soman in vivo.
