Description

Verfahren zur Erhöhung der Gerinnungsfähigkeit von .tierischem Blut Es wurde gefunden, daß cetylschwefelsaures Natrium in geringen Konzentrationen die Fähigkeit besitzt, die Gerinnung von tierischem Blut zu beschleunigen.Process for increasing the coagulability of animal blood It has been found that sodium cetylsulfuric acid in low concentrations the Ability to accelerate the coagulation of animal blood.

Abgesehen von den nur in vivo wirksamen Präparaten, z. B. Euphyllin, kennt man bereits ein Verfahren zur Erhöhung der Gerinnungsfähigkeit von tierischem Blut dur cli Zusatz von Elektrolyten unter Mutverwendung van Pektin. Bei diesem Verfahren tritt aber keine echte irreversible Gerinnung ein, sondern das Fibrin fällt in einem löslichen Zustande ,aus.Apart from the preparations that are only effective in vivo, e.g. B. Euphyllin, one already knows a method for increasing the coagulability of animal products Blood through the addition of electrolytes with the courage to use pectin. With this one In the process, however, there is no real irreversible coagulation, but the fibrin precipitates in a soluble state.

Im Gegensatz hierzu handelt es sich bei dem neuen Verfahren um eine echte irreversible Gerinnung, die außerdem von dem Zusatz von Elektrolyten unabhängig ist. , Das cetylschwefelsaure Natrium wirkt in vitro und in vivo. Es ist schon in verhältnismäßig geringen Mengen wirksam. Z. B. erreicht man in vitro die beste Wirkung bei menschlichem Blut durch einen Zusatz von o,oo6 v. H. Bei einem Gehaltan cetylschwefelsaurem Natrium von o, r v. H. und darüber wird die Blutgerinnung ebenso wie bei Elektrolyt -i- P.ektinzusatz hemmend beeinflußt. Intravenöse Injektionen von io bis zoom. cetylschwefelsaurem Natrium setzen beim Kaninchen (Gewicht etwa 3 kg) die Blutgerinnungszeit (gemessen bei 20°) von ¢ bis ä Minuten auf 1/2 bis i Minute herab. Die Wirkung in vivo erreicht spätestens 6o Minuten nach der Injektion den Höchstwert und klingt später langsam ab.In contrast to this, the new process is a real irreversible coagulation, which is also independent of the addition of electrolytes. , Sodium cetylsulfuric acid acts in vitro and in vivo. It is effective even in relatively small amounts. For example, the best effect on human blood is achieved in vitro by adding 0.06%. H. If the content of sodium cetylsulphurate is o, r v. H. and above, blood coagulation is inhibited, as is the case with the addition of electrolyte -i pectin. Intravenous injections from io to zoom. In rabbits (weight about 3 kg), sodium cetylsulfuric acid reduces the blood coagulation time (measured at 20 °) from ¢ to - minutes to 1/2 to 1 minute. The in vivo effect reaches its maximum value no later than 60 minutes after the injection and slowly subsides later.

Die Fähigkeit des cetylscliwefelsauren Natriums, die Gerinnung des Blutes zu beschleunigen, kann man in der Weise benutzen, da.ß man das Präparat einem Tier injiziert und diesem darauf Blut abzapft oder indem man das Blut außerhalb des Körpers mit dem Mittel, das zweckmäßig vorher in Wasser gelöst oder auf einer Trägersubstanz fein vei7-* teilt wird, zusammenbringt. Man kann auc#I . Tierblut, das zunächst durch Zusatz von Heparin oder gerinnungshemmenden Algenstoffen flüssig gehalten wurde, durch Zugabe von cetylschwefelsaurem Natrium wieder die Fähigkeit verleihen, zu gerinnen.The ability of sodium cetylsulfuric acid to coagulate the To accelerate blood, one can use it in such a way that one gives the preparation to one Injected animal and then draw blood from it or by doing the Blood outside the body with the agent, which has expediently previously dissolved in water or is finely divided on a carrier substance, brings together. You can also # I . Animal blood, which is initially obtained by adding heparin or anticoagulant algae substances was kept liquid, by adding sodium cetylsulfurate again the Confer the ability to curdle.

Das Verfahren kann dazu dienen, die Serum- bzw. Fibringewinnung zu erleichtern. Die Abkürzung der Gerinnungszeit und das raschere und vollständigere Absitzen des Serums vom Blutkuchen ist ein wesentlicher Vorteil, der sich auf die Beschaffenheit und Menge des gewonnenen Serums günstig auswirkt. Die Blutbestandteile sind durcnweg leicht zersetzliche Stoffe. Außerdem sollen sie in den meisten Fällen keimfrei gewonnen ,werden. Zersetzung und Verunreinigungen lassen sich # um so leichter vermeiden, je "kürzer dic , 4elandlungsdauer ist. Ähnli^hes gilt auch "yön" der - Fibringewinnung. Das neue Verfahren .bringt somit einen wesentlichen technischen Fortschritt mit sich.The method can be used to obtain the serum or fibrin facilitate. The shortening of the clotting time and the faster and more complete Settling the serum off the blood cake is a major benefit that affects the Has a beneficial effect on the quality and quantity of the serum obtained. The blood components are easily decomposable substances. Also, they should in most cases aseptically obtained. Decomposition and impurities are the easier to remove Avoid, the shorter the duration of the landing. The same applies to the "yön" - Fibin recovery. The new process. Thus brings an essential technical Progress with itself.
