    Description / Table of Contents: Summary The activities of 8 key-enzymes (glucose-6-phosphate-dehydrogenase, 6-phosphogluconate-dehydrogenase, hexokinase, phosphofructokinase, pyruvate kinase, glycerol-3-phosphate-dehydrogenase, malate dehydrogenase, phosphoglucomutase) have been estimated in the subcutaneous adipose tissue of 27 patients with hyperlipemia of different origin. We found that the activities of glucose-6-phosphate-dehydrogenase and hexokinase were diminished significantly, what means a lowered utilisation of glucose. From these results in connection with a diminished activity of glycerol-3-phosphate-dehydrogenase it can be concluded that lipogenesis in human adipose tissue is diminished at the same time.
    Notes: Zusammenfassung Im subcutanen Fettgewebe von 27 Patienten mit Hyperlipidämien verschiedener Genese wurden die Aktivitäten von 8 Schlüsselenzymen bestimmt (Glucose-6-Phosphat-Dehydrogenase, 6-Phosphogluconat-Dehydrogenase, Hexokinase, Phosphofructokinase, Pyruvatkinase, Glycerin-3-Phosphat-Dehydrogenase, Malatdehydrogenase, Glucophosphomutase). Dabei fand sich eine hochsignifikante Herabsetzung der Glucose-6-Phosphat-Dehydrogenase- und der Hexokinase-Aktivität, woraus auf eine verminderte Glucoseverwertung geschlossen werden kann. In Verbindung damit spricht die deutlich erniedrigte Aktivität der Glycerin-3-Phosphat-Dehydrogenase für eine gleichzeitig herabgesetzte Lipogenese im menschlichen Fettgewebe.

    Description / Table of Contents: Zusammenfassung Im subcutanen Fettgewebe von Mensch und Schwein sowie im epididymalen Fettgewebe der Ratte wurden Enzymmuster bestimmt: Glucose-6-Phosphatdehydrogenase (EC 1.1.1.49), 6-Phosphogluconatdehydrogenase (EC 1.1.1.44), Hexokinase (EC 2.7.1.1), Phosphofructokinase (EC 2.7.1.11), Pyruvatkinase (EC 2.7.1.40), Glucophosphomutase (EC 2.7.5.1), Glycerin-3-Phosphatdehydrogenase (EC 1.1.1.8), Malatdehydrogenase (EC 1.1.1.37), Glutamatpyruvattransaminase (EC 2.6.1.2), Glutamatoxalacetattransaminase (EC 2.6.1.1), Glutamatdehydrogenase (EC 1.4.1.3), Citrate Cleavage Enzyme (EC 4.1.3.8), Malic Enzyme (EC 1.1.1.38), Glycerokinase (EC 2.7.1.30), Glucose-6-Phosphatase (EC 3.1.3.9) und Fructose-1,6-Diphosphatase (EC 3.1.3.11). Trotz der unterschiedlichen Lokalisation der Gewebe und des verschiedenen Gehaltes an löslichem Extraktprotein (Ratte:Mensch:Schwein=21,7±1,6:21,0±1,9:5,4±0,5mg/g Frischgewicht) finden sich annähernd übereinstimmende Enzymaktivitätsmuster. Bei allen drei Species ist die Phosphofructokinase das limitierende Glykolyse-Enzym und erfolgt der Glucoseabbau offensichtlich überwiegend über den Pentose-Phosphat-Shunt; eine weitere Gemeinsamkeit ist das Fehlen von Glycerokinase-Aktivität. Bezogen auf Extraktprotein liegen jedoch fast alle Enzymaktivitäten im menschlichen Fettgewebe um annähernd eine Zehnerpotenz niedriger als bei Ratte und Schwein. Im Gegensatz zu diesen beiden Species ist im Humanfettgewebe kein Citrate-Cleavage-Enzyme nachweisbar.
    Notes: Summary Enzyme patterns (Glucose-6-Phosphatdehydrogenase (EC 1.1.1.49), 6-Phosphogluconatdehydrogenase (EC 1.1.1.44), Hexokinase (EC 2.7.1.1), Phosphofructokinase (EC 2.7.1.11), Pyruvatkinase (EC 2.7.1.40), Glucophosphomutase (EC 2.7.5.1), Glycerin-3-Phosphatdehydrogenase (EC 1.1.1.8), Malatdehydrogenase (EC 1.1.1.37), Glutamatpyruvattransaminase (EC 2.6.1.2), Glutamatoxalacetattransaminase (EC 2.6.1.1), Glutamatdehydrogenase (EC 1.4.1.3), Citrate Cleavage Enzyme (EC 4.1.3.8), Malic Enzyme (EC 1.1.1.38), Glycerokinase (EC 2.7.1.30), Glucose-6-Phosphatase (EC 3.1.3.9) and Fructose-1,6-Diphosphatase (EC 3.1.3.11)) have been measured in subcutaneous adipose tissue of man and pig and in the epididymal fat pads of rats. The conduct of soluble extract-protein was equal in rat (21.7±1.6 mg/g) and man (21.0±1.9 mg/g) but different in pig (5.4±0.5 mg/g). In all three species the pattern was nearly the same; phosphofructokinase was the rate-limiting enzyme of glycolysis; most of the glucose degradation in white adipose tissue seems to be done via the pentose-phosphate-shunt; there was no measurable activity of glycerokinase. In human adipose tissue—where nearly all enzyme activities were about ten times lower—there was no citrate cleavage enzyme either.

    Description / Table of Contents: Zusammenfassung Bei einer Patientin mit einer reticulocytogenen lipophagen Granulomatose in Unterhautfettgewebe und Lunge sowie zwei Patientinnen mit Mamma-Carcinom wurden im Tumorgewebe die Aktivitäten folgender Enzyme bestimmt: G-6-PDH, 6-PGDH, HK, PFK, PK, GDH, GK, MDH, GPM, GPT, GOT und GluDH. In Übereinstimmung mit der Literatur fanden wir in beiden Geweben ein tumorspezifisches Enzymmuster. In den Retikuloseknoten ließ sich darüberhinaus eine deutlich meßbare Aktivität der Glycerokinase nachweisen. Die „Michaelis-Konstante“ für Glycerin unterschied sich nicht von dem für Lebergewebe angegebenen Wert. Gut meßbare Aktivitäten dieses Enzyms sind bisher nur für Leber- und Nierengewebe angegeben worden.
    Notes: Summary The activities of the following enzymes were determined in a patient showing reticulo-cytogenous lipophagic granulomatosis in her subcutaneous adipose tissue and the lungs, as well as in two patients with carcinoma of the breast: G-6-PDH, 6-PGDH, HK, PFK, PK, GHD, GK, MDH, GPM, GPT, GOT and GluDH. We found a tumor-specific enzyme pattern in both tissues, a finding which is in accord with the results published in the literature. Furthermore, a well measurable glycerokinase activity in the reticulo-cytogenous lipophagic granulomas could be demonstrated as well. The Michaelis-Menten constant for glycerol was not different from the values found in hepatic tissue. So far, these enzymatic activities had been found to be easily assessable in liver and kidney tissue only.

    Description / Table of Contents: Zusammenfassung Bei Ratte, Maus, Meerschweinchen, Mensch, Kaninchen und Schwein konnte in vitro — und bei den beiden letztgenannten Species auch in vivo — eine lipolytische Wirkung eines von uns aus Schweinehypophysen dargestellten lipidmobilisierenden Polypeptids nachgewiesen werden. Beim Menschen zeigte sich nur ein Effekt auf die Glycerin-, nicht auf die Fettsäurefreisetzung; beim Schwein war in vitro keine Lipolysestimulation zu erzielen, in vivo dagegen eine starke Wirkung. Wie Untersuchungen der Cyclo-AMP-Phosphodiesterase-Aktivität im Fettgewebe des Menschen und der Ratte ergeben haben, ist als möglicher Wirkungsmechanismus eine Hemmung dieses Enzyms zu diskutieren. — Dieser Nachweis einer offenbar universellen Wirksamkeit stellt einen weiteren Hinweis auf das Vorhandensein eines speziellen lipidmobilisierenden Peptids in der Hypophyse dar.
    Notes: Summary The lipolytic effect of a polypeptide isolated from pig pituitaries was investigated in vitro and/or in vivo in 6 species. In vitro the peptide was active in the rat (MED 0,1 µg/ml), in the mouse and guinea-pig (MED 1,0 µg/ml each) and in the rabbit (MED 0,01 µg/ml). In human adipose tissue there was only an effect on glycerol liberation, in the pig no effect at all. But in vivo a strong action could be demonstrated in the minipig by injection of 100 µg/kg intravenously. Phosphodiesterase activity in adipose tissue of man and rat was inhibited by the peptide.

    Notes: Summary IgM antibodies to cytomegalovirus (CMV) could be detected in about 7 per cent of 629 pregnant women, whereas in 225 nonpregnant control women of similar age distribution only 2.6 per cent showed CMV IgM antibodies. Intrauterine CMV infections were almost exclusively detected among the CMV IgM positive gravides. The high incidence of CMV IgM antibodies in pregnant women can be possibly explained by an increased rate of CMV reactivations during pregnancy. We were able to show that during CMV reactivation an intrauterine infection might occur.

    Notes: Abstract Forty-two patients with herpes simplex virus infections were tested for neutralizing serum IgM antibodies. A technique in which serum antibody fluorescein staining was combined with sucrose gradient centrifugation facilitated the isolation of the serum IgM fraction for the use in neutralization tests. In nearly all cases with primary infection, especially those presenting heavy clinical signs (encephalitis/meningitis) the IgM tests were positive. In one case we could detect the IgM antibodies for 11 weeks after the onset of the illness, in another case in cerebrospinal fluid samples for 6 weeks. In localized herpes infections, which were mostly due to reactivations, serum IgM antibodies could only rarely be demonstrated. Among the serologic tests used in this study (NT, CFT, IFT, ACIFT), only the CFT beside the NT (with certain reservations) can be applied for subtyping HSV serum antibodies.

    Notes: Abstract A method for the purification and concentration of Cytomegalovirus nucleocapsids and particles complete with envelope is described. Antibody to either nucleocapsid or envelope antigens can be detected in human sera. In patients with CMV disease the antibodies to the envelope antigen could not be detected before the 3rd week after the beginning of disease whereas antibodies to the nucleocapsid were detected earlier.

    Notes: Abstract By absorption with protein A and specific immunosorption using insolubilized adsorbentia (CPG), a method was developed for rapid elimination of IgG and IgA from patients' serum samples. This test technique was examined in the diagnosis of rubella infections, i.e., rubella-specific IgM antibodies. The procedure has proven to be as reliable as determinations carried out with IgM fractions separated on a sucrose density gradient.

    Notes: Abstract 11 HSV strains isolated from patient's material are typed by an indirect immunofluorescent technique and the results are compared to those of the “rct”-test (distinction by temperature markers). Producing both satisfactory results, the first method is superior to the second one because of its rapidity.
