Mit Natriumphosphat ebenso wie mit Natriumsulfat gelingt es nicht, ein trockenes 100"/ges Tuberkulin herzustellen ; Natriumkarbonat hat zwar die Eigenschaft, Tuberkulin in sehr konzentrierter Form zu trocknen, doch bewirkt es eine totale Zerstörung der spezifischen Substanzen der Bakterienpräparate.
EMI2.1
neuer technischer Effekt, zumal das Bakterienpräparat bei dieser Behandlung voll wirksaut geblieben ist und seine ursprünglichen physiologischen Eigenschaften bewahrt hat.
Das mit Natriumtetraborat gewonnene haltbare Trockenpräparat tötet in der gleichen Menge und in der gleichen Zeit ein tuberkulöses Meerschweinchen, wie eine entsprechende frische Tuberkulinverdünnung ohne den Salzzusatz.
Auch im Präzipitationsversuch zeigt das Natrinmtetraborat-Trockenpräparat genau dioselben Werte, wie eine frisch bereitete raino Tuberkulintösung gleicher Konzentration.
Unter Präzipitation versteht man eine spezifische Reaktion, welche beispielsweise Tuberkulin mit einem spezifischen Antltuberkulinserum liefert Sie besteht darin, dass beim Zusammenbringen von Serum mit Tuberkulin oder Tuberkulinverdünnungen in der an sich vollkommen klaren Mischung eine deutliche Nioderschlagsbildung auftritt. Aus dem Grade der Verdünnung, in welcher eben noch Präzipitierung erfolgt, lässt sich der Gehalt der Tuberkulinmischung an spezifischer Substanz berechnen.
Das Glyterin ist in den Tuberkelbazillenpraparaten nicht als Konservierungsmittel enthalton, sondern als ein Surrogat, welches a priori für die Herstellung und Gewinnung, z. B. des Tuberkulins, unumgängliche Vorbedingung ist. Es ist eine lästige Beimengung, die den Trocknungsprozess wesentlich erschwert, die aber nicht zu vermeiden ist, weil die Tuberkelbazillen nur in einer Bouillon gedeihen, die Glyzerin enthalt. Die Herstellung eines Trockenpraparates aus einer glyzerinfreien Kulturflüssigkeit wäre ungleich leichter und einfacher gewesen ; es ist aber ganz und gar nicht angängig. dem Originaltuberkulin das Glyzerin I.
U entziehen, da es hiedurch eine Beeinträchtigung seiner ursprünglichen Eigenschaften erfahren würde und da durch Glyzerin auch die Wasserlöslichkeit des Natriumtotraborates wesentlich verbessert wird.
EMI2.2
Uurch Vermischen dor foln gepul'erton Substanz mit Kochsalz bzw. sterilem Milchzucker lassen sich, entsprechend den homöopathischen Triturationen, verschiedenprozentige Verreibungen herstellen. Diese können zu exakt dosierten Tabletten gepresst werden. welche Im Bedarfsfa ! le in bestimmten, bequem injizierbaren Mengen Wasser aufgelöst werden.

With sodium phosphate as well as with sodium sulphate it is not possible to produce a dry 100 "/ total tuberculin; Sodium carbonate has the property of drying tuberculin in a very concentrated form, but it causes a total destruction of the specific substances of the bacterial preparations.
EMI2.1
new technical effect, especially since the bacterial preparation remained fully effective during this treatment and retained its original physiological properties.
The durable dry preparation obtained with sodium tetraborate kills a tuberculous guinea pig in the same amount and in the same time as a corresponding fresh tuberculin dilution without the addition of salt.
In the precipitation experiment, the sodium tetraborate dry preparation shows exactly the same values as a freshly prepared raino tuberculin solution of the same concentration.
Precipitation is understood to be a specific reaction which, for example, delivers tuberculin with a specific anti-tuberculin serum. It consists in the fact that when serum is brought together with tuberculin or tuberculin dilutions in the mixture, which is completely clear in itself, a significant formation of rain occurs. The amount of specific substance in the tuberculin mixture can be calculated from the degree of dilution at which precipitation has just taken place.
The glyterin is not contained in the tubercle bacilli preparations as a preservative, but as a surrogate, which a priori for the production and extraction, e.g. B. of tuberculin, is an unavoidable precondition. It is an annoying additive that makes the drying process much more difficult, but it cannot be avoided because the tubercle bacilli only thrive in a broth that contains glycerine. The production of a dry preparation from a glycerine-free culture liquid would have been much easier and simpler; but it is by no means accessible. the original tuberculin is glycerine I.
Withdraw U, as this would impair its original properties and since glycerine also significantly improves the water solubility of the sodium dead traborate.
EMI2.2
By mixing the powdered powdered substance with table salt or sterile milk sugar, triturations of different percentages can be produced in accordance with homeopathic triturations. These can be pressed into precisely dosed tablets. which in need fa! oils can be dissolved in specific, conveniently injectable amounts of water.
