    Notizen: Summary An ultrastructural study of the cells that line air spaces in human pulmonary fibrosis is reported. Intimate associations between these cells and cellular elements in the interstitium were consistently found in biopsies from 25 cases. Cytoplasmic extensions of cuboidal pneumocytes protruded through discontinuities in the subjacent basement membrane. Attenuated cells having structural properties of fibroblasts were situated on connective tissue that formed the walls of numerous air spaces. In this situation, a basement membrane was not demonstrable. These heretofore undescribed features suggest a dynamic interaction between certain mesenchymal and epithelial elements in the fibrotic lung.

    Notizen: Summary Twenty-nine patients with chronic pancreatitis had a significantly greater IR-GIP response to a test meal than 15 controls. This increased response was not related to the degree of steatorrhoea or glucose intolerance. It was most marked in a group of patients with moderately impaired IRI release and medium steatorrhoea. From this is concluded that the IR-GIP response to a test meal is determined by at least two factors: 1. feedback control via insulin secretion, 2. assimilation of fat. In chronic pancreatitis endocrine insufficiency may induce an exaggerated GIP response and severe exocrine insufficiency may prevent fat induced GIP release. Gastrin is not involved in the different GIP response in patients with chronic pancreatitis.

    Notizen: Summary The response of serum immunoreactive gastric inhibitory polypeptide (IR-GIP), gastrin (IRG) and insulin (IRI) to a mixed standard meal was measured in 15 controls, 6 patients with coeliac disease, 26 patients with chronic pancreatitis and 6 patients with chronic pancreatitis and partial duodenopancreatectomy (Whipple's procedure). Serum levels of IR-GIP, IRG and IRI were significantly reduced in patients with coeliac disease. The serum glucose increase was significantly smaller only during the first hour after the meal. Since small intestinal GIP- and G-cells are situated mainly in the glands of duodenal and jejunal mucosa their absolute number is not significantly reduced in coeliac disease. It is suggested that the release of IR-GIP and duodenal IRG is influenced by the rate of absorption of nutrients. In patients with chronic pancreatitis the IR-GIP release is significantly greater than in controls, the IRG release normal and the IRI response delayed. After Whipple's procedure the IR-GIP response is increased significantly while the IRG secretion is abolished. This demonstrates that the duodenum is not necessary for GIP release and that pancreatic and jejunal gastrin are without clinical significance.

    Beschreibung / Inhaltsverzeichnis: Summary A simple continuous filtration leukapheresis has been devised whereby two Leuko-Pak filters can be charged and eluted within 5 h with approximately 12 l of blood in a closed system of tubes. Blood flows by means of gravity without the use of pumps. Without premedication with prednisolone the average yield from 10 donors was 3.66×1010 granulocytes per leukapheresis and after premedication with 150 mg prednisolone orally it was 6.44×1010 granulocytes per leukapheresis. The in vitro function of filter granulocytes was not reduced even after premedication with prednisolone. In comparison with leukapheresis by blood cell separators this modified method of filtration leukapheresis offers the following advantages: 1) the granulocyte yield per litre of whole blood processed is higher, 2) technical assistants in a blood-bank can carry out the method on several donors simultaneously, 3) the method is more economical than leukapheresis by blood cell separators.
    Notizen: Zusammenfassung Es wurde eine einfache kontinuierliche Filtrationsleukapherese (FL) zur Gewinnung von Granulozyten entwickelt, mit der zwei Leuko-Pak-Filter innerhalb von 5 h mit etwa 12 Liter Blut im geschlossenen System beschickt und eluiert werden können. Der Blutfluß erfolgt dabei ohne Pumpe allein durch Schwerkraft. Die durchschnittliche Ausbeute betrug bei 10 Spendern ohne Vorbehandlung mit Prednisolon 3,66×1010 Granulozyten pro Leukapherese, nach Vorbehandlung mit 150 mg Prednisolon p.o. 6,44×1010 Granulozyten pro Leukapherese. In vitro-Tests zeigten, auch nach Gabe von Prednisolon, keine Einschränkung der Funktionsfähigkeit der Filtergranulozyten. Die vorliegende modifizierte Form der FL hat im Vergleich zur Leukapherese durch Blutzellseparatoren folgende Vorteile: 1. Die Granulozytenausbeute bezogen auf Liter separiertes Vollblut ist höher. 2. Die Methode kann durch Hilfspersonal in einer Blutbank an mehreren Spendern gleichzeitig durchgeführt werden und sie ist 3. wirtschaftlicher als die Leukapherese mit Blutzellseparatoren.
