   In der Patentschrift Nr. 70277 ist ein Verfahren zur Herstellung von Kontrastbildnern beschrieben, welches darin besteht, dass bekannte Metalle oder deren Verbindungen in feingepulvertem Zustande mit heissem Paraffin übergossen werden und dieses Gemisch während des Erkaltens des Paraffins sorgfältigst verrieben wird. Das nach dem Erkalten an den Partikelchen der Kontrastmittel fest anhaftende Paraffin soll dem Schwergewicht dieser Stoffe beim Einbringen in Flüssigkeiten entgegenwirken und so eine gleichmässige Verteilung des Kontrastbildners im Magen und Darmkanal ermöglichen. Zur Erhöhung der Wirkung des Paraffins werden dem Gemisch noch spezifisch sehr leichte Körper hinzugefügt, wie z. B. Pflanzensamen oder gepulvert Holzkohle. 



   In weiterer Ausbildung dieser Erfindung hat sich nun gezeigt, dass man an Stelle dieser leichten Substanzen Tragant oder andere   PBanzensehleime   oder   Pektinstoffe   dem Kontrastbildner beimengen kann. Durch den Zusatz dieser Stoffe wird eine sehr gleichmässige Verteilung des Kontrastbildners in der Magenflüssigkeit bewirkt, andererseits hat ein so hergestellter Kontrastbildner den Vorzug, dass er mit noch weniger Widerwillen genommen wird, als der nach dem Stammpatent hergestellte.

   Patent specification No. 70277 describes a process for the production of contrast formers, which consists in pouring hot paraffin over known metals or their compounds in a finely powdered state and triturating this mixture very carefully while the paraffin cools. The paraffin, which adheres firmly to the particles of the contrast agent after cooling, is intended to counteract the heavy weight of these substances when they are introduced into liquids and thus enable the contrast-forming agent to be evenly distributed in the stomach and intestinal canal. To increase the effect of the paraffin, specifically very light bodies are added to the mixture, such as. B. Plant seeds or powdered charcoal.



   In a further development of this invention it has now been shown that, instead of these light substances, tragacanth or other Panzereal slimes or pectin substances can be added to the contrasting agent. The addition of these substances results in a very even distribution of the contrast former in the gastric fluid; on the other hand, a contrast former produced in this way has the advantage that it is taken with even less reluctance than that produced according to the parent patent.
