  Verfahren zur Darstellung eines die Blutgerinnung befördernden Mittels aus Blut. 



   Es wurde gefunden, dass sich aus Blut ein Präparat herstellen lässt, welches in hohem Gr & de die Eigenschaft besitzt, die Blutgerinnung zu befördern. Zu dessen Isolierung verfährt man wie folgt :
In 40 1 Magnesium-und Oxalatblut gibt man   120 I   hochprozentigen Sprit und lässt unter stetem Rühren und unter Kühlen mit   Rückflusskühler   5 Stunden kochen. Hierauf wird der Spritextrakt bei 700 C filtriert, der in Sprit unlösliche Anteil wird leicht ausausgepresst und nochmals mit 40   l   hochprozentigem Sprit 5 Stunden in der oben angegebenen Weise gekocht. Es wird wiederum bei 700 C filtriert und der Rückstand scharf ausgepresst. 



   Die Spritlösung wird sofort in hohem Vakuum und bei niedriger Temperatur ein-   gedampft   und gegen das Ende der Destillation werden 10   l   destilliertes Wasser eingesaugt und die Destillation so geleitet, dass zum Schluss noch 16 bis 20   1   Emulsion verbleiben. Diese Emulsion wird : 1. mit 5 1 Chloroform, 2. mit 3   I   Chloroform je 10 Minuten aus- 
 EMI1.1 
 Kohlenwasserstoffe, wie Tetrachlorkohlenstoff, Tetrachloräthan,   Perchloräthylen.   Pentachlor- äthen usw. angewendet werden. 



     Die Chloroformlösung   wird mit Aceton versetzt. wobe eine starke Fällung entsteht, 
 EMI1.2 
 wird mit Äther extrahiert und die resultierende Ätherlösung im Vakuum zur Trockne eingedampft. Für die praktische Verwendung wird das erhaltene Präparat in geeigneter Weise verdünnt. 



   Reaktion. 
 EMI1.3 
 physiologische Kochsalzlösung nach 55 Minuten   nicht   fest wird. 



   Das so erhaltene hochwirksame und haltbare Präparat ist eine   llpoidartigf   Substanz von   hellbrauner   bis gelblichweisser Farbe (je nach   der H) ntart. aus der   es hergestellt wurde), welche Kohlenstoff, Wasserstoff. Phosphor und Spuren von Eisen enthält. In Benzol und Tetrachlorkohlenstoff ist dieselbe sehr leicht, in Chloroform, Äther, Toluol und Schwefelkohlenstoff ziemlich leicht, in Alkohol nur teilweise löslich mit gelber Farbe ; in Aceton

  Process for preparing a blood coagulation agent from blood.



   It has been found that a preparation can be made from blood which has the property to a large extent of promoting blood clotting. To isolate it, proceed as follows:
In 40 l of magnesium and oxalate blood, 120 l of high-proof fuel are added and the mixture is left to boil for 5 hours while stirring and cooling with a reflux condenser. The fuel extract is then filtered at 700 ° C., the portion that is insoluble in fuel is gently squeezed out and boiled again with 40 l of high-proof fuel for 5 hours in the manner indicated above. It is again filtered at 700 ° C. and the residue is squeezed out sharply.



   The fuel solution is immediately evaporated in a high vacuum and at low temperature and towards the end of the distillation 10 l of distilled water are sucked in and the distillation is conducted in such a way that 16 to 20 l of emulsion remain at the end. This emulsion is: 1. with 5 l of chloroform, 2. with 3 l of chloroform for 10 minutes
 EMI1.1
 Hydrocarbons such as carbon tetrachloride, tetrachloroethane, perchlorethylene. Pentachlorethylene etc. are used.



     Acetone is added to the chloroform solution. where a heavy precipitation occurs,
 EMI1.2
 is extracted with ether and the resulting ether solution is evaporated to dryness in vacuo. For practical use, the obtained preparation is appropriately diluted.



   Reaction.
 EMI1.3
 physiological saline solution does not set after 55 minutes.



   The highly effective and durable preparation obtained in this way is a poid-like substance of light brown to yellowish-white color (depending on the species). from which it was made), which carbon, hydrogen. Contains phosphorus and traces of iron. It is very light in benzene and carbon tetrachloride, fairly light in chloroform, ether, toluene, and carbon disulfide, and only partially soluble in alcohol, with a yellow color; in acetone
