Description

Verfahren zur Herstellung öliger Suspensionen des Hypophysenvorderlappenhormons Man hat schon Lösungen oder Suspensionen von Hormonen, wie dem blutzuckersenkenden Pankreashorm@on, den Sexualhormonen oder Hypophysenvorderlappenhormon, in ölen :oder unverseifbaren Lipoiden hergestellt. Die vom gonadotropen Hypophysenvorderlappenhormon (im folgenden HVH genannt) hergestellten Suspensionen in Olivenöl zeigten jedoch im Gegensatz zu den Angaben im Schrifttum den Nachteil, daß sie in kurzer Zeit absetzen und infolgedessen inhomogen werden, wodurch ihre Verwendung in der Praxis beeinträchtigt wird.Process for the preparation of oily suspensions of anterior pituitary lobe hormone You already have solutions or suspensions of hormones, such as those that lower blood sugar Pancreashorm @ on, the sex hormones or anterior pituitary lobe hormone, in oils: or made unsaponifiable lipoids. The gonadotropic anterior pituitary hormone (hereinafter referred to as HVH) produced suspensions in olive oil, however In contrast to the information in the literature, the disadvantage that they are removed in a short time and consequently become inhomogeneous, thereby affecting their practical use will.

Es wurde nun gefunden, daß man zu haltbaren, nicht absetzenden Suspensionen des HVH dadurch gelangen kann, daß man die Suspensionen des Hormons in physiologisch unschädlichen ölen unter Zusatz von Wollfett herstellt.It has now been found that durable, non-settling suspensions can be obtained of the HVH can get through the fact that the suspensions of the hormone in physiological produces harmless oils with the addition of wool fat.

Eine Vorreinigung des HVH-Präparates z. B. durch Entfernen des Salzes mittels Dialyse hat sich als vorteilhaft erwiesen, weil hierdurch das spezifische Gewicht der HVH-Präparate wesentlich erniedrigt und die Suspendierung somit erleichtert wird. Die Abtrennung der Salze kann außer durch Dialyse auch durch Adsorption oder Ausfällung des Hormons in üblicher Weise vorgenommen werden.A pre-cleaning of the HVH preparation z. B. by removing the salt by means of dialysis has proven to be advantageous because it enables the specific The weight of the HVH preparations is significantly reduced and suspension is therefore easier will. The salts can be separated off by means of dialysis or also by adsorption or Precipitation of the hormone can be done in the usual way.

Als physiologisch unschädliche öle kommen solche tierischer und pflanzlicher Herkunft in Frage, wie z. B. Erdnußöl, Sesamöl und Olivenöl.The oils that are physiologically harmless are those of animal and vegetable origin Origin in question, such as B. peanut oil, sesame oil and olive oil.

Man verwendet zweckmäßig vorgereinigtes, d. h. praktisch säurefreies Wollfett, wie es unter dem Namen adeps lange im Handel ist. Der Zusatz an Wollfett beträgt vorteilhaft 5 bis 15 %, berechnet auf die Menge des angewendeten öles. Lösungen des HVH in Olivenöl, denen io 0;o adeps lange zugesietzt wurde, haben sich als besonders geeignet erwiesen: Beispiel 5 g eines durch Alkoholfällung aus Schwangerenharn erhaltenen Rohproduktes werden nach einer Extraktion mit 50%igem Alkohol und anschließender Ausfällung mit Alkohol einer Dialyse unterworfen. Aus der Innenflüssigkeit des Dialysators wird ein größtenteils von Salzen befreites HVH erhalten, das man nun mit kleinen Mengen einer Mischung von io g Wollfett und ioo Ccm Olivenöl verreibt. Die erhaltene Suspension setzt im Gegensatz zu einer reisöligen Suspension des HVH-Rollproduktes nicht ab, ist reizlos und viel haltbarer als eine wässerige Lösung des gleichen Ausgangsproduktes.It is advisable to use pre-cleaned, ie practically acid-free, wool grease, as it has long been on the market under the name adeps. The addition of wool fat is advantageously 5 and 1 5%, calculated on the amount of the applied oil. Solutions of HVH in olive oil, to which 100% adeps were added for a long time, have proven to be particularly suitable: Example 5 g of a crude product obtained by alcohol precipitation from pregnant woman's urine are subjected to dialysis after extraction with 50% alcohol and subsequent precipitation with alcohol . From the internal liquid of the dialyzer, a largely salt-free HVH is obtained, which is then triturated with small amounts of a mixture of 10 g of wool fat and 100 cc of olive oil. In contrast to a rice oil-based suspension of the HVH roll product, the suspension obtained does not settle, is non-irritating and much more durable than an aqueous solution of the same starting product.
