Abstract

Le remede pour le traitement des infections virales de l'oeil et d'autres organes a partir de substance antivirale, d'adjuvants et vehicules, renferme en outre un ou plusieurs antibiotiques connus, le cas echeant dans une preparation separee. Les infections bacteriennes presentes a cote des infections virales, seront ainsi combattues grace a l'antibiotique, empechant ainsi la formation d'enzymes bacteriens, comme l'hyaluronidase, qui inhibent la formation d'interferon dans la cellule. La presence d'une infection bacterienne avant et/ou pendant une infection virale peut etre mise en evidence par la presence d'enzymes bacteriens avant et pendant la maladie virale.The remedy for the treatment of viral infections of the eye and other organs using antiviral substance, adjuvants and vehicles, further contains one or more known antibiotics, where appropriate in a separate preparation. Bacterial infections present alongside viral infections will thus be fought thanks to the antibiotic, thus preventing the formation of bacterial enzymes, such as hyaluronidase, which inhibit the formation of interferon in the cell. The presence of a bacterial infection before and/or during a viral infection can be evidenced by the presence of bacterial enzymes before and during the viral disease.

Description

Mittel zur Behandlung von Virusinfektionen des Auges und anderer OrganeAgents for the treatment of viral infections of the eye and other organs
Die Erfindung betrifft ein Mittel zur Behandlung von Virusinfektionen des Auges und anderer Organe.The invention relates to an agent for the treatment of viral infections of the eye and other organs.
Zur Behandlung von Virusinfektionen des Auges wurden bisher schon antivi¬rale Substanzen wie Interferon verwendet (Emödi u.a., 1974, Jordan, 1974). Es wurde damit im allgemeinen eine Besserung der Virusinfektionen erreicht, doch konnte vielfach ein erneutes Auftreten einer akuten VirusInfektion nicht verhindert werden.Antiviral substances such as interferon have been used to treat viral infections of the eye (Emödi et al., 1974, Jordan, 1974). An improvement in the viral infections was generally achieved, but in many cases a recurrence of an acute viral infection could not be prevented.
Ziel der Erfindung ist ein Mittel zur Behandlung von Virusinfektionen des Auges und anderer Organe, und zwar sowohl zur vorbeugenden Behandlung als auch zur Behandlung akuter Infektionen, wie sie z.B. durch den Herpes sim¬plex-Virus oder den Adenovirus hervorgerufen werden, welches eine wirksame prophylaktische Behandlung und eine rasche und sehr wirksame Bekämpfung akuter Virusinfektionen ermöglicht.The aim of the invention is an agent for the treatment of viral infections of the eye and other organs, both for preventive treatment and for the treatment of acute infections, such as those e.g. can be caused by the herpes simplex virus or the adenovirus, which enables effective prophylactic treatment and rapid and very effective control of acute viral infections.
Die Erfindung schlägt ein Mittel zur Behandlung von Virusinfektionen des Auges und anderer Organe aus antiviraler Substanz, Adjuvanzien und Vehicu¬la vor, das dadurch gekennzeichnet ist, daß es außerdem, gegebenenfalls in Form einer gesonderten Zubereitung, ein bekanntes Antibiotikum oder mehrere bekannte Antibiotika enthält.The invention proposes an agent for the treatment of viral infections of the eye and other organs from antiviral substance, adjuvants and vehicle, which is characterized in that it also contains, if necessary in the form of a separate preparation, a known antibiotic or several known antibiotics.
Das Mittel der Erfindung eimöglicht eine wirksame und rasche Bekämpfung von Virusinfektionen. Es wurde nämlich im Rahmen der Erfindung festgestellt, daß ein sehr enger Zusammenhang zwischen einer bakteriellen Infektion und einer Viruserkrankung besteht, d.h. , daß einer Viruserkrankung immer eine bakterielle Infektion vorangeht oder eine Viruserkrankung von einer solchen bakteriellen Infektion begleitet wird. Vor und während einer Viruser krankung sind bakterielle Enzyme beim Krankheitsherd vorhanden. Diese bak teriellen Enzyme, wie die Hyaluronidase, beeinträchtigen bzw. hindern eine Bildung von antiviralem Interferon in der Zelle, wodurch ein Eindringen und ein Ausbreiten des Virus ermöglicht wird.The agent of the invention enables effective and rapid control of viral infections. It has been found in the context of the invention that there is a very close connection between a bacterial infection and a viral disease, ie that a viral disease is always a bacterial infection or a viral disease is accompanied by such a bacterial infection. Before and during a viral disease, bacterial enzymes are present in the focus of the disease. These bacterial enzymes, such as hyaluronidase, impair or prevent the formation of antiviral interferon in the cell, which enables the virus to penetrate and spread.
Im Laboratorium kann eine bakterielle Infektion neben einer Virusinfektio und dadurch der Beginn einer Viruserkrankung nach folgender Methode festge stellt werden:In the laboratory, a bacterial infection can be determined in addition to a viral infection and thus the beginning of a viral disease using the following method:
Die Methode besteht aus dem Anfärben eines Glucos-aminoglycansubstrats mit Toluidinblau (einer orthochromatischen Farbe) und dem darauffolgenden Entfärben, um dadurch einen Halo (aufgehellter Hof) an der Reaktionsstelle zwischen Substrat und dem dies zersetzenden Enzyms zu erhalten.The method consists of staining a glucose aminoglycan substrate with toluidine blue (an orthochromatic color) and then decolourising it, thereby obtaining a halo (lightened area) at the reaction site between the substrate and the decomposing enzyme.
