Description

Verfahren zur Herstellung von arzneimitteln gegen Krebs Die experimentelle Krebsforschung beweist die Übertragbarkeit vieler Tumoren durch beimpfung von einem Individuum auf ein anderes. Auch bei Autotranspiantation können neue Tumoren entstehen. Hierauf beruht ein Vorurteil gegen die therapeutische Anwendung von Tumormaterial. Process for the preparation of drugs against cancer The experimental Cancer research proves the transferability of many tumors by inoculating one Individual to another. Autotranspants can also develop new tumors. A prejudice against the therapeutic use of tumor material is based on this.

Es hat sich nun aber gezeigt, dass am Wachstum undder Ausbreitung eines Tumors eine sich entwickelnde immunologische Toleranz mit Schuld trägt.It has now been shown, however, that the growth and spread of a tumor is to blame for developing immunological tolerance.

Diese Immuntoleranz kann man-durchbrechen, wenn man zunächst lymphatisches Gewebe auf den Krebspatienten überträgt und dann in Art einer aktiven Immunisierung die körpereigene Geschwulst unter Zusatz eines Adjuvans in geeigneter Dosierung wiederholt reinjiziert. Die Verwendung der körpereigenen Geschwulst ist wegen der geschwulst und damit individualspezifischen Geschwulstantigene erforderlich. Diese Behandlung muss über längere Zeitspannen hinweg erfolgen. Deshalb ist es notwendig, Geschwülste, die durch chirurgische Eingriffe entfernt oder reseziert werden, zu Dauerpräparaten zu verarbeiten.You can break through this immune tolerance if you first have a lymphatic system Tissue is transferred to the cancer patient and then in an active immunization manner the body's own tumor with the addition of an adjuvant in a suitable dosage reinjected repeatedly. The use of the body's tumor is because of the tumor and thus individual-specific tumor genes required. These Treatment must be carried out over long periods of time. Therefore it is necessary Growths that are removed or resected by surgery, increase To process permanent preparations.

Zur Vermeidung autokatalytischer Vorgänge muss die Konservierung unmittelbar nach der Entnahme erfolgen. Es soll möglichst die Ausgangsgeschwulst und ihre Metastasen erfasst werden, weil in Metastasen zusätzliche Antigenarten auftreten können. Bei der Verarbeitung ist es zweckmässig, durch sehr schonende Hydrolyse die Gewebezellen chemisch aufzuschliessen. Dadurch wird die Übertragbarkeit der Geschwulst beseitigt und ihre unmittelbare Antigenität verstärkt. Hierzu hat sich das Verfahren des Patents 1 090 821 bewährt. Bei diesem erfolgt die Aufschliessung der aus der Geschwulst hergestellten Trookenpulver mit Hilfe von Dämpfen chemischer Reagenzien im Vacuum bei Normaltemperatur. Solche Hydrolysate sind jahrelang haltbar und lassen sich dann in einer Adjuvanslösung jederzeit zur aktiven Itrunisierung des Patienten oder tibermittlertiere zur Herstellung eines Antikörperserums verwenden Verständlicherweise übersteigt die Herstellung solcher individueller-Präparate den Rahmen der klinischen ärztliche Tätigkeit und kann nur in Speziallaboratorien erfolgen. Beispiel Von dem Geschwulstpräparat eines bestimmten Patienten, das durch chirurgisuche Eingriffe entnommen wurde, wird der nicht zur histologischen Diagnose verwendete Anteil möglichst kurz nach der Entnahme unter sterilen Kautelen in kirschkerngrosse Stücke zerschnitten. Diese werden in flüssigem Stickstoff eingefroren und dann in Trockeneis (Kohlensäureschnee), das in flüssigem Stickstoff vorgekühlt ist, zum Versand gebracht. In einem Speziallaboratorium wird das Material erneut in flüssigem Stickstoff tiefgekühlt, in einer ebenfalls tiefgekühlten Mühle fein pulverisiert, dann gefriergetrocknet und anschliessend im Vacuum bei Zimmertemperatur dem Dampf von konzentrierter Schwefelsäure ausgesetzt. Dieser Schwefelsäuredampf wird auf dem Substrat mehrmals niedergeschlagen durch Verringerung des Vacuums. Zuletzt wird das Vacuum soweit erhöht, dass die nicht zur Reaktion gekommene Schwefelsäure verdampft und abgesaugt werden kann. Das Pulver wird dann unter Luftabschluss in Stickstoffatmosphäre bis zur Benutzung aufbewahrt. Unmittelbar vor der Applikation wird es in einer wässrigen Adjuvanslösung, einer kolloidalen Komplexverbindung aus Aluminiumhydroxyd und Kieselsäure in geeigneter Konzentrqtion aufgeschwemmt.To avoid autocatalytic processes, the preservation must be immediate after removal. If possible, the original tumor and its metastases should be identified because additional types of antigens can occur in metastases. at During processing, it is advisable to hydrolyse the tissue cells very gently to be chemically digested. This eliminates the transferability of the tumor and enhances their immediate antigenicity. To do this, the procedure of the patent 1 090 821 proven. With this, the decomposition takes place from the tumor Trooken powder produced with the help of vapors of chemical reagents in a vacuum at normal temperature. Such hydrolysates can be kept for years and can be then in an adjuvant solution at any time for active Itrunization of the patient or Understandably, using intermediate animals to produce an antibody serum the production of such individual preparations exceeds the scope of clinical medical activity and can only take place in special laboratories. example From the tumor preparation of a specific patient that was subjected to surgical interventions was removed, the portion not used for the histological diagnosis is, if possible, used shortly after removal, cut into pieces the size of a cherry stone under sterile conditions. These are frozen in liquid nitrogen and then in dry ice (carbon dioxide snow), which has been pre-cooled in liquid nitrogen. In a special laboratory the material is frozen again in liquid nitrogen, also in one Finely powdered in a frozen grinder, then freeze-dried and then exposed to the vapor of concentrated sulfuric acid in a vacuum at room temperature. This sulfuric acid vapor is deposited several times on the substrate Reduction of the vacuum. Finally, the vacuum is increased so much that it does not any sulfuric acid that has reacted can be evaporated and suctioned off. The powder is then stored under the exclusion of air in a nitrogen atmosphere until use. Immediately before application, it is in an aqueous adjuvant solution, a colloidal complex compound of aluminum hydroxide and silica in suitable Concentration bloated.
