    Notes: Bronchial epithelial damage occurs regularly in bronchial asthma, but it is not known whether such damage occurs in the mucosa of nasal polyps. We obtained nasal polyp tissues from thirty patients and we examined these tissues for evidence of epithelial damage. Immediately after resection, polyp tissue was fixed in Karnovsky's fixative, embedded in methacrylate and stained with Giemsa pH 6-5. Normal nasal tissue from eight patients undergoing nasal septal reconstruction was similarly processed. As a disease control, we examined tissue from eight patients with nasal polyps associated with cystic fibrosis. Tissues were viewed by microscopy and epithelial damage was expressed as the percent of surface involved. Twenty-eight of the thirty patients with idiopathic nasal polps (93%) showed complete loss of nasal mucosa in varying degrees (range 3-81% of surface; mean, 29%). All patients showed evidence of some epithelial damage, either complete loss or marked desquamation (range 9-99% of surface; mean 54%). In contrast, six of eight biopsies from patients undergoing septal reconstruction and five of eight nasal polyps from patients with cystic fibrosis showed little or no evidence of epithelial damage. The results indicate that nasal polyps regularly show evidence of epithelial damage similar to that seen in bronchial asthma, and this abnormality may partly explain the rhinorrhea which is prominently associated with nasal polyps.

    Notes: Zusammenfassung Anhand eines Krankengutes von 91 Rezidivoperationen an den Gallenwegen von 1952 bis 1964 wird über die Symptomatologie und diagnostik, über die Anzeigestellung zum Eingriff und über das operative Vorgehen berichtet. Zweit- oder Mehrfacheingriffe an den Gallenwegen sind naturgemäß mit einer höheren Komplikationsrate und Mortalität belastet als Ersteingriffe. Im eigenen Krankengut betrug die Gesamtmortalität 8,8%. Die durch Fragebogen ermittelten Spätergebnisse waren als befriedigend zu bezeichnen.

    Description / Table of Contents: Zusammenfassung Fortschritte auf dem Gebiet der Leber, Gallenwegs- und Pankreaschirurgie betreffen heute vor allem die präoperative Diagnostik: Die gezielte Arteriographie der Oberbauchorgane, aber auch Leber- und Pankreasszinti graphie lassen pathologische Prozesse lokalisieren, z. B. Leberabscesse oder endokrine Pankreastumoren. Ohne jede Belästigung und Gefährdung des Patienten läßt sich die Ultraschalltomographie durchführen, die ebenfalls bemerkenswerte Ergebnisse zeigt. Die intraoperative Diagnostik, vor allem die Radiomanometrie der Gallenwege 1äßt Steine, Tumoren und Stenosen im Gallenwegssystem ausschließen. Wird sie nicht routinemäßig angewendet, so ergeben sich mehr als 10°f, Fehldeutungen, die dann zum „Postcholecystektomiesyndrom” führen. In der Pfortaderchirurgie ergibt eine zusätzliche druckadaptierte Arterialisation des Pfort-aderstumpfes bessere Ergebnisse; die postoperative Encephalopathie 1äßt sich dadurch verhindern. In der Pankreatitisbehandlung geht der Trend zur aktiven operativen Behandlung, bei der Behandlung maligner Pankreastumoren zur Radikaloperation, wenn Operabilitdt besteht.
    Notes: Summary Today Progress in surgery of the liver, biliary system and the pancreas concerns mainly the preoperative diagnosis: The selective arteriography of the upper abdominal organs but also the scintillation scanning of liver and pancreas allows to localize a pathologic process as for instance abscesses of the liver or endocrine tumors of the pancreas. The ultrasonic tomography which can be performed without any harm or danger for the patient also shows remarkable results. The intraoperative diagnostic mainly the radiomanometry of the bile ducts makes it possible to exclude stones, tumors and stenosis in the biliary system. If it is not applied routinely it will result in more than 10°/u of wrong diagnosis which then will lead to the “Postcholecystectomysyndrome”. In the surgery of portal hypertension the additional pressure adapted arterialization of the stump of the portal vein results in better results thus preventing the postoperative encephalopathy. In the management of pancreatitis there is a trend to-wards active operative treatment and in the management of malignant tumors of the pancreas towards radical surgery if operability is given.

    Notes: Zusammenfassung Für optische und elektrische Untersuchungen von Alkalihalogeniden spielt die thermische Vorgeschichte der Kristalle eine große Rolle. Das gilt insbesondere dann, wenn man dünne Kristallschichten bei hohen Temperaturen untersucht. Um einen Einblick in die Vorgänge bei hohen Temperaturen zu gewinnen, wurden die Veränderungen der Oberflächen von Einkristallen beim Verdampfen an Luft untersucht und dabei verschiedene Oberflächenstrukturen beobachtet. Die Fig. 1–3 und 5–11 beziehen sich auf äußere Oberflächen, die Fig. 12 auf die gröbste Form einer „inneren Oberfläche“, einen mikroskopischen Spalt.

    Description / Table of Contents: Summary Cytogenetic investigations in patients with primary amenorrhoea revealed two cases with a structural chromosome mosaic. Chromosome analysis was done in leukocyte cultures of peripheral blood. A 21 years old patient with infantilism, hypoplastic genitalia, but normal heigh (case 1) showed mosaicism of the type 46/XX–46/Xx with supposed deletion of a part of the long arm of one X-chromosome in one of both stem-lines. The possible origin of this deletion is discussed. Buccal mucosa smears of this patient showed only few Barr-bodies (8.5%), and these tended to be smaller than usually seen. — In a 19 year old patient with the clinical signs of Turner-syndrome (case 2) mosaicism of the type 45/XO–46/X-isochromosome-X of the long arm was found. In this case Barr-bodies larger than usually seen were present in 7.5% of cells in buccal mucosa smears. A scheme is presented suggesting the possible mode of origin of this isochromosome.
    Notes: Zusammenfassung Bei cytogenetischen Untersuchungen an Patientinnen mit primärer Amenorrhoe wurden unter Verwendung kurzzeitiger Kulturen von weißen Blutzellen zwei Fälle mit Strukturmosaik nachgewiesen. Eine 21jährige Patientin mit Infantilismus und hypoplastischem Genitale bei normaler Körpergröße (Fall 1) zeigte bei der Chromosomenuntersuchung ein Mosaik vom Typ 46/XX–46/Xx (wahrscheinliche Deletion eines Teils des langen Arms des X-Chromosoms) im Verhältnis 3:2. Ein möglicher Entstehungsmodus der X-Deletion wird diskutiert. In Wangenschleimhautabstrichen fanden sich nur 8,5%, teilweise besonders kleine Barr-Körperchen. — Bei einer 19jährigen Patientin mit Kleinwuchs und den klinischen Zeichen eines Turnersyndroms (Fall 2) ergab die Chromosomenuntersuchung ein Mosaik vom Typ 45/XO–46/X-Isochrom-X des langen Arms im Verhältnis 2,5:1. In Wangenschleimhautabstrichen waren 7,5% auffällig große Barr-Körperchen vorhanden. Die Entstehung eines Isochromosoms im Rahmen eines derartigen Mosaiks wird an Hand einer schematischen Darstellung zu verdeutlichen versucht, die die Möglichkeit eines paracentromerischen Transversalbruches eines X-Chromosoms berücksichtigt.

    Notes: Abstract Hydrographic data taken at 25 equally spaced stations along 35°N in April 1976 and again in July 1977 are compared for the longitude range 139–163° W and the depth range 0–1,000 m. A continuous subsurface layer is found, centered at 100 m and extending more than 2,000 km in the east-west direction, in which the temperature and salinity were significantly lower and the density and concentrations of oxygen and three nutrients were higher in the summer of 1977 than in the spring of 1976. In the upper 50 m the temperature and salinity were higher and the density and concentrations of oxygen and nutrients were lower in the summer of 1977 than in the spring of 1976. These relationships are concluded to be due to an annual variation by association with other existing data sets in the same region. The annual variation of hydrographic properties in the upper 200 m can be qualitatively explained by an annual variation in the north-south component of the permanent circulation, which is caused by an annual variation in the large-scale north-south pressure gradient (related to the northward temperature gradient). The observations are consistent with a northward current near the surface and a southward current near 100 m which are both faster in summer than in winter (and spring).
