    Description / Table of Contents: Durch das steigende Informationsangebot und einen relativ leichten Einstieg finden immer mehr Ophthalmologen Zugang zum Internet. Ein jederzeit und jederorts abrufbarer ophthalmologischer Befundbildatlas mit zugehörigem ICD-Schlüssel im World Wide Web bietet verschiedene Möglichkeiten, wie z.B. Aufruf eines typischen Befundbildes zum differentialdiagnostischen Vergleich, zur eigenen Weiterbildung oder Verwendung für den eigenen Bedarf (u.a. Präsentationen). Bis jetzt wurden bereits über 500 typische Befundbilder ausgewählt, digitalisiert und in eine Datenbank integriert, die über 4700 ICD-standardisierte und -codierte Diagnosen enthält. Bildbezogene Diagnosen und die Bilder werden mit dieser Datenbank verknüpft. Nach Eingabe eines diagnostischen Suchbegriffs bewirken spezielle Programmskripte die Datenbanksuche und die Ausgabe der Suchergebnisse in automatisch erstellten Web-Seiten. Die gefundenen Bilder werden zur Minimierung des Datentransfers zunächst in Kleinformat (Thumbnails) ausgegeben und sind auf Mausklick im Vollformat zu erhalten. Neben Diagnose und ICD-Schlüssel-Nummer werden zu jedem Bild der Autor, ein diagnostischer Hinweis (Hausdiagnose) und ein Kommentar bzw. Kommentarmöglichkeit angeboten. Der von uns entwickelte Gießener Ophthalmologische Bildatlas ist unter der Internetadresse www.med.uni-giessen.de [Überlokale Infosysteme] abrufbar. Er ermöglicht einen gezielten, raschen und kostenlosen Diagnose- und Befundbildabruf mit zugehörigem ICD-Schlüssel und stellt eine sinnvolle Ergänzung zum Studium von gedruckten ophthalmologischen Bildatlanten dar.
    Notes: The Internet has become a powerful, international source for information, and it has shown an exponential growth because of the ease of access and the immediate availability of information. We introduced a new ophthalmological atlas including ICD coding on the World Wide Web. So far, more than 500 lantern slides of typical and interesting ophthalmological findings have been selected and digitized. These pictures were integrated in a data base, which was arranged for ease and speed of search and retrieval. In its background, the data base contains a list of over 4700 ICD-encoded diagnoses to which the picture-documented findings are linked. Comments on pictures can be added by the author or by users. The data base contains several lists, such as a list of ICD codes and diagnoses, a list of all pictures with corresponding diagnoses, a list of all diagnoses and number of picture, a list of those diagnoses for which the corresponding picture is available, as well as a list of comments on each picture. Special program scripts handle the user's search key words for diagnoses and extract the required information out of the data base, using Windows NT. Search results are presented on an automatically built-up webpage. To provide fast speed of search all pictures initially are shown in a small format (thumbnails) with little amount of data. The related full-size picture is retrieved by a single mouse click. Moreover, the name and institution of the author, diagnostical hints and comments on pictures by the author or by users are offered for each diagnosis available. The Giessen Ophthalmological Picture Atlas can be reached under www.med.uni-giessen.de in the Internet. It allows a fast search free of charge from all over the world and, therefore, offers an additional option to obtain specific ophthalmological information for various purposes.

    Notes: The dynamic wetting behaviour on a perfluorinated, low-energy solid has been investigated for a carbohydrate-modified phenylsiloxane surfactant. The surfactant concentration, the rate of interface generation and the [solid/liquid interface area] : [liquid/vapour interface area] ratio were varied systematically. Dynamic data for the liquid/vapour (γlv) and solid/liquid (γsl) interfacial tension as well as their Lifshitz-van der Waals and donor-acceptor contributions were determined under strictly controlled conditions. Since γsl reacts sensitively to variations of the surfactant concentration and the rate of interface generation, the covering of the liquid/non-polar solid interface is assumed to be a spreading limiting factor. The corresponding γlv values remain constant and close to those obtained under equilibrium conditions. Copyright © 1998 John Wiley & Sons, Ltd.

    Notes: New siloxanyl-modified carbohydrate surfactants of the amide and glycoside type have been synthesized by coupling between defined as well as higher-molecular-weight siloxanes and carbohydrate structures via spacers of different lengths and hydrophilic power. Linear and branched monohydrogen di-, tri-, tetra- and penta-siloxanes and polyhydrogen siloxanes as well as mono- and di-saccharide lactone structures have been found to be good starting materials for the synthesis of amides, often in quantitative yield, whereas glycosides had to be prepared in low-yield multistep sequences including protection/deprotection steps. Selected strategies were applied to polysiloxanes yielding quantitatively a broad variety of carbohydrate-modified comb-like structures. The new substances were characterized by means of 13C NMR spectroscopy, GC, capillary GC, GC-MS coupling and elemental analysis.

    Notes: The synthesis of carbohydrate surfactants bearing carbosilane, silane, polysilane and non-permethylated siloxane moieties is described. These surfactants consist of three structural elements: (1) a silicon-containing moiety, (2) a spacer and (3) a carbohydrate unit. Additionally two different types of mixed structures have been synthesized: (a) single-chained carbosilane-siloxane surfactants and (b) double-chained combinations of carbo- silanes, silanes and siloxanes. The wetting behaviour of the key intermediates, the allyl glycidyl derivatives, has been investigated by static surface tension (γlv, σ) and wetting tension (γsv-γsl, α) measurements on a non-polar perfluorinated surface (FEP® plate). The contact angles obtained for these pure liquids are not a linear function of the surface tension but depend on the polarity of the substructures. © 1998 John Wiley & Sons, Ltd.
