    Description / Table of Contents: Summary L-Chains of normal gamma-G-globulin can be seperated on CM-Sephadex in two fractions, called L A and L B , which occure in a constant ratio. Both fractions gave an immunoprecipitate with anti L-lambda and anti L-kappa serum. Each fraction yields on polyacrylamid-discelektrophoresis three protein bonds. L-chains prepared from gamma-G-myelomproteins show on CM-Sephadex different elution pattern: a) Increase of the fraction L A consisting mostly of the kappa or lambda typ. b) Increase of the L A fraction consiting only of the kappa typ or c) Equal quantities of L A and L B fraction, which react immunologicaly as pure kappa chains. The L-chains differ in the polyacrylamid-discelektrophoresis of the myelomproteins and their fractions as well from each other as in comparison with the normal L-chains. A difference exists with regard to the number of protein bands and their migration velocity.
    Notes: Zusammenfassung L-Ketten normaler Gamma-G-Globuline lassen sich an CM Sephadex in einem konstanten Mengenverhältnis in zwei Unterfraktionen, L A und L B , auftrennen. Beide Fraktionen präcipitieren mit Anti-L-Kappa und Anti-L-Lambda-Seren. Sie lassen sich in der Acrylamidgelelektrophorese in je drei Proteinbanden auftrennen. Aus Gamma-G-Myelomseren präparierte L-Ketten zeigen an CM Sephadex verschiedene Elutionsbilder: Vermehrung der Fraktion L B mit Überwiegen der Kappa- oder Lambda-Form, Vermehrung der L A -Fraktion mit alleinigem Nachweis der Kappa-Ketten oder gleiche Quantitäten der L A - und L B -Komponenten mit immunologischem Nachweis reiner Kappa-Ketten. In der Discelektrophorese zeigen die L-Ketten der Myelomseren und deren Unterfraktionen sowohl untereinander als auch gegenüber den normalen L-Ketten eine unterschiedliche Anzahl von Proteinbanden und verschiedene Wanderungsgeschwindigkeiten.

    Description / Table of Contents: Summary 12 patients with chronic hepatitis and 12 patients with liver cirrhosis as proved by laparascopy and histological examination received peroral doses of 800 or 1200 mg acetanilide. 12 healthy persons of the same age served as a controll. 2, 6 and 24 hrs after giving the dose free N-acetyl-p-aminophenol and its glucuronide were determined in the serum and in 24 hrs urine. Further it was serched for free acetanilide. In the urine the concentration of total conjuga ed N-acetyl-p-aminophenol was measured too. Patients with chronic hepatitis and with liver cirrhosis showed a decrease in the glucuronide and an increase in free N-acetyl-p-aminophenol after a dose of 1200 mg acetanilide. Acetanilide itself could not be detected. It is assumed that a decrease in the activity of glucuronyl-transferase in the liver is responsible for the diminished formation of N-acetyl-p-aminophenol-glucuronide.
    Notes: Zusammenfassung Je 12 Patienten mit laparoskopisch und histologisch gesicherter chronischer Hepatitis und Lebercirrhose erhielten peroral 800 bzw. 1200 mg Acetanilid. Als Kontrolle dienten altersmäßig entsprechende Lebergesunde. 2, 6 und 24 Std nach der Belastung wurden das freie und das an Glucuronsäure gebundene N-acetyl-p-aminophenol im Serum und im 24 Std-Urin bestimmt. Außerdem wurde versucht, freies, unverändertes Acetanilid nachzuweisen. Im Urin wurde ferner die Konzentration des total konjugierten N-acetyl-p-aminphenols gemessen. Bei Patienten mit chronischer Hepatitis und Lebercirrhose waren besonders nach 1200 mg Acetanilid eine Verminderung des Glucuronids und eine Zunahme der freien Verbindung festzustellen. Acetanilid konnte nicht nachgewiesen werden. Als Ursache für die verminderte Glucuronidbildung wird eine Abnahme der Glucuronyltransferaseaktivität in der Leber für wahrscheinlich gehalten.

    Description / Table of Contents: Summary Sera of γ1A, γ1M and γSS paraproteins were subjected to gel filtration on sephadex G200 before and after treatment with cysteamine. The fractions obtained were examined by ultrazentrifugation and by immunological methods. The second fraction after gelfiltration before and after cysteamine treatment were rechromatographed on sephadex DEAE and TEAE. The subfractions obtained by this procedure were examined by ultrazentrifugation, immunological methods and by starchgel-electrophoresis. Cysteamine treatment causes splitting off of a globulin from fraction I after gelfiltration with S=6 to 7×1013. This component is eluted with the fraction II due to its low molecular weight. According to the agar diffusion test the split off globulin behaves like an atypical γ1A globulin. From the γ1 macroglobulin an immunological active γ1M globulin is splitt off by cysteamine. This has a sedimentation constant of S=6.34×10−13 and is eluted with the fraction II. The second fractions after gelfiltration of sera before and after cysteamine treatment show different chromatographic patterns on sephadex DEAE and TEAE, both, quantitatively and qualitatively. It is concluded, that this is caused by a chenged primary structure of the paraproteins compared to normale globulins. There are also differences in the chromatographic patterns of sera from different patientes. The compounds after sephadex DEAE and TEAE chromatography do not differ in their sedimentation constants but they prove to be heterogenous in starchgel-electrophoresis. So far the individual specifity of the paraproteins is proved.
    Notes: Zusammenfassung Die Seren von γ A-, γ M- und γ G-Paraproteinen wurden vor und nach Behandlung mit Cysteamin an Sephadex G200 gelfiltriert. Die erhaltenen Fraktionen wurden sedimentationsanalytisch und immunologisch untersucht. Die II. Fraktionen nach Gelfiltration vor und nach Cysteamin wurden an den Anionenaustauschern Sephadex DEAE und TEAE rechromatographiert. Die so erhaltenen Unterfraktionen wurden ebenfalls sedimentationsanalytisch, immunologisch und in der Stärkegelelektrophorese untersucht. Durch das Cysteamin wird bei den γ A-Paraproteinen aus der I. Fraktion nach Gelfiltration ein Globulin mit der Sedimentationskonstanten S=6 bis 7×10−13 abgespalten, das auf Grund des geringeren Molekulargewichtes in der II. Komponente eluiert wird. Bei dem abgespaltenen Globulin handelt es sich nach dem Agardiffusionstest um ein atypisches γ A-Globulin. Bei den γ-Makroglobulinen wird durch Cysteamin aus der I. Fraktion nach Gelfiltration ein immunologisch aktives γ M-Globulin abgespalten, das eine Sedimentationskonstante S=6,34×10−13 aufweist und in der II. Komponente eluiert wird. Die Rechromatographie der II. Fraktionen nach Gelfiltration vor und nach Behandlung der Seren mit Cysteamin an Sephadex DEAE und TEAE zeigt gegenüber der Norm ein in quantitativer und qualitativer Hinsicht abweichendes Bild. Daraus wird auf eine veränderte Primärstruktur der Paraproteine geschlossen. Auch untereinander weichen die Chromatogramme der untersuchten Seren deutlich voneinander ab. Diese Komponenten nach Rechromatographie an Sephadex DEAE sind größtenteils in bezug auf die Sedimentationskonstante einheitlich, in der Stärkegelelektrophorese sind die Komponenten heterogen. Damit ist die Individualspezifität der Paraproteine erneut belegt.

    Notes: Abstract Esophagitis has increasingly been implicated as a cause of chronic laryngitis and there is some evidence that gastro-esophageal reflux disease (GERD) is more common in patients with laryngitis. The aim of this study was to evaluate whether patients with esophagitis and laryngitis responded to treatment with omeprazole. Of 74 consecutive patients with endoscopically proven GERD, 21 had laryngitis. These 21 patients with associated esophagitis and chronic laryngitis were treated for 4 weeks with omeprazole 40 mg per day. After 2 weeks of treatment and at the conclusion of the study, 2 weeks later, esophagoscopy and laryngoscopy were performed and the patients responded to a questionnaire on their symptoms. The follow-up period was 1 year. Twenty-one of the 74 patients (28.4%) had esophagitis (grade I,n=12; grade II,n=9) and associated laryngitis (grade I,n=14; grade II,n=7). The severity of the esophagitis accorded with the severity of the laryngitis. After 2 weeks' treatment with omeprazole, both the esophageal and the laryngeal symptoms had improved in all 21 patients. Endoscopically, the healing rates were 62% for esophagitis and 33.3% for laryngitis. At the end of the study period, at 4 weeks, all patients were symptom-free and the esophagitis and laryngitis had healed completely. No patient suffered from drug-induced side effects. Patients with associated laryngitis and esophagitis should be given adequate anti-reflux therapy. Both the laryngeal and esophageal symptoms improved with the omeprazole treatment, suggesting that reflux was the underlying etiology.

    Description / Table of Contents: Zusammenfassung Meerschweinchen mit chronischer Hepatitis infolge Langzeitbehandlung mit Thioacetamid zeigen elektronenoptisch eine Verminderung des endoplasmatischen Reticulums in der Leber. Magenschleimhaut und Nieren bleiben histologisch unverändert. Die mit o-Aminophenol undβ-Methylumbelliferon gemessenen Aktivitäten der Glucuronyltransferase sind in Leber und Magenschleimhaut vermindert, in den Nieren vermehrt. Die Anilinglucuronidierung ist in der Leber gesteigert, während in Magenschleimhaut bei Kontroll- und Versuchsgruppe keine Anilinglucuronidierung nachweisbar ist. p-Nitrophenol- und Bilirubinglucuronidierung sind in der Leber vermindert, in den Nieren unverändert. Diese Befunde stützen die Annahme, daß es eine spezielle Glucuronyltransferase für die Synthese von Bilirubinglucuroniden und ein weiteres Enzym für die Bildung N-glycosidischer Glucuronidbindungen gibt sowie mindestens zwei verschiedene Transferasen für die Synthese o-glykosidischer Glucuronide. Die UDPGA-Konzentration wird erniedrigt in der Leber und bleibt in den Nieren unverändert. Die Aktivität der UDPG-Dehydrogenase bleibt in beiden Organen gleich.
    Notes: Summary Livers of guinea pigs with chronic hepatitis after chronic intoxication with thioacetamide reveal in electron microscopy a reduction of the endoplasmatic reticulum. Gastric mucosa and kidneys are histologically unchanged. The activities of glucuronyl transferase as measured with o-aminophenol andβ-methylumbelliferone are reduced in liver and in gastric mucosa and increased, however, in kidneys. There is a rise in the conjugation of anilin with glucuronic acid in the liver, and there is no conjugation of anilin detectable in gastric mucosa. The conjugation of p-nitrophenol and bilirubin is reduced in the liver and unchanged in the kidneys. These results lead to the suggestions that there exists an individual glucuronyl transferase synthesizing bilirubin glucuronide and a separate enzyme forming N-glycosidic glucuronide linkages and that there are at least two distinct glucuronyl transferases synthesizing o-glycosidic lincages. The concentration of UDPGA in the affected livers is reduced whereas it is unchanged in the kidneys. The activity of UDPG-dehydrogenase remains constant in both organs.
