Description

       

  
 



  La présente invention concerne un implant se présentant pour la forme d'une pastille destiné à la médecine humaine et un procédé de fabrication de cet implant. 



  Il a été observé cliniquement, que certains tissus frais d'origine animale ou des extraits obtenus à partir de ces tissus, ont des effets bénéfiques en application gériatrique, ou dans le traitement de certaines pathologies dégénératives. 



  Néanmoins, ces produits présentent quelques inconvénients, dans la pratique de leur administration, tant au point de vue de leur conservation, que dans la durée de leurs effets. 



  L'utilisation de la forme implant présente l'avantage de contrôles rigoureux d'activité, de stérilité et d'inocuité, sur les méthodes de prélèvement et d'utilisation d'organes frais ou d'extraits d'organes en solution. 



  La présente invention permet de remédier à ces inconvénients en proposant un implant sous une forme solide, dont deux des trois matières premières constitutives sont d'origine humaine, et bien acceptées par l'organisme humain; de plus, cette forme permet une diffusion prolongée des principes actifs dans le temps. 



  L'implant selon l'invention est caractérisé par le fait qu'il est constitué d'un mélange:
 d'environ 200 mg d'extrait placentaire d'origine humaine, lyophilisé correspondant à 40 g de placenta en tissu frais, 
 de 0,3 ml de collagène natif d'origine placentaire humaine en suspension correspondant à environ 1,5 mg d'extrait sec,
 et de 10 mg d'extrait de bourgeon dentaire embryonnaire lyophilisé d'origine bovine. 



  Le procédé de fabrication de l'implant est caractérisé par le fait que l'on mélange de l'extrait placentaire d'origine humaine lyophilisé avec du collagène natif d'origine placentaire humaine et de l'extrait de bourgeon dentaire embryonnaire d'origine bovine dans les proportions suivantes par implant à obtenir:
 - environ 200 mg d'extrait placentaire d'origine humaine lyophilisé correspondant à 40 g de placenta en tissu frais,
 - 0,3 ml de collagène natif d'origine placentaire humaine en suspension correspondant à 1,5 mg d'extrait sec,
 - 10 mg d'extrait de bourgeon dentaire embryonnaire lyophilisé d'origine bovine, 



  que l'on met le tout en solution dans l'eau pour préparations injectables, que l'on stérilise la solution par filtrations stérilisantes connues en soi, que l'on introduit le filtrat stérile dans des flacons de 5 ml, chaque flacon correspondant à un implant, que l'on lyo philise par des méthodes connues le contenu des flacons, obtenant ainsi une pastille, et on bouche et sertit les flacons sous atmosphère stérile. 



  Les avantages de ce produit sous cette forme galénique, constitué en somme d'un extrait placentaire d'origine humaine lyophilisé sur un support de glycoprotéines de structure (collagène natif, extrait de bourgeon dentaire embryonnaire) partiellement d'origine humaine (collagène natif), sont que sa forme solide rend possible sa manipulation et son application en tant qu'implant; le collagène natif permet à l'implant une diffusion prolongée dans le temps, ainsi en fonction des individus et des cas spécifiques un implant suffit pour une durée de six mois. 



  L'implant a des propriétés revitalisantes et stimulantes sur certains métabolismes en voie de déclin ce qui permet son utilisation en gériatrie. 



  Le produit s'est relevé cliniquement actif sur la polyarthrite rhumatoïde ce qui a été confirmé par des contrôles biologiques effectués dans les cas traités, en particulier par des dosages des immunoglobines spécifiques, des interleukines, et l'étude de la formule sanguine. 



  Pour la fabrication du produit on a besoin de trois matières premières à savoir:
 - extrait de placenta d'origine humaine lyophilisé,
 - collagène actif d'origine placentaire humaine en suspension, 
 - extrait sec de bourgeon dentaire embryonnaire d'origine bovine. 



  Les proportions à respecter pour l'implant à fabriquer sont:
 - environ 200 mg d'extrait de placenta d'origine humaine lyophilisé, ce qui correspond à 40 g de placenta en tissu frais,
 - 0,3 ml de collagène natif d'origine humaine correspondant à 1,5 mg d'extrait sec,
 - 10 mg d'extrait sec de bourgeon dentaire embryonnaire (tissu mésenchymateux) lyophilisé d'origine bovine, 



   le tout est mis en solution dans l'eau pour préparations injectables, par exemple de l'eau destillée apyro gène QS (quantité suffisante) par ml. Ensuite le mélange est stérilisé par filtrations stérilisantes connues en soi, et mis dans des flacons de 5 ml. Dans chaque flacon on introduit 1 ml de la solution obtenue après les filtrations stérilisantes, la quantité de 1 ml contenant les quantités de matière précitées pour faire un implant. Le contenu des flacons est lyophilisé par des méthodes habituelles. L'implant se présente sous la forme d'une pastille déposée au fond du flacon. Après la lyophilisation les flacons sont bouchés et sertis sous atmosphère stérile. De préférence un agent antiseptique est introduit dans le mélange avant sa stérilisation. 



  
 



  The present invention relates to an implant in the form of a pellet for human medicine and a method of manufacturing this implant.



  It has been observed clinically that certain fresh tissues of animal origin or extracts obtained from these tissues have beneficial effects in geriatric application, or in the treatment of certain degenerative pathologies.



  However, these products have some drawbacks, in the practice of their administration, both from the point of view of their conservation, and in the duration of their effects.



  The use of the implant form has the advantage of rigorous controls of activity, sterility and harmlessness, over the methods of removal and use of fresh organs or organ extracts in solution.



  The present invention makes it possible to remedy these drawbacks by proposing an implant in a solid form, two of the three constituent raw materials of which are of human origin, and well accepted by the human organism; moreover, this form allows a prolonged diffusion of the active ingredients over time.



  The implant according to the invention is characterized in that it consists of a mixture:
 about 200 mg of placental extract of human origin, lyophilized corresponding to 40 g of placenta in fresh tissue,
 0.3 ml of native collagen of human placental origin in suspension corresponding to approximately 1.5 mg of dry extract,
 and 10 mg of lyophilized embryonic dental bud extract of bovine origin.



  The implant manufacturing process is characterized by the fact that lyophilized human placental extract is mixed with native human placental collagen and bovine embryonic tooth bud extract. in the following proportions per implant to be obtained:
 - approximately 200 mg of lyophilized placental extract of human origin corresponding to 40 g of placenta in fresh tissue,
 - 0.3 ml of native collagen of human placental origin in suspension corresponding to 1.5 mg of dry extract,
 - 10 mg of lyophilized embryonic dental bud extract of bovine origin,



  that the whole is dissolved in water for injections, that the solution is sterilized by sterilizing filtrations known per se, that the sterile filtrate is introduced into 5 ml vials, each vial corresponding to an implant, which is lyophilized by known methods the contents of the bottles, thus obtaining a lozenge, and the bottles are capped and crimped under a sterile atmosphere.



  The advantages of this product in this galenical form, consisting in sum of a placental extract of human origin lyophilized on a support of structural glycoproteins (native collagen, embryonic bud bud extract) partially of human origin (native collagen), are that its solid form makes it possible to handle and apply it as an implant; native collagen allows the implant to spread over a long period of time, so depending on individuals and specific cases an implant is sufficient for a period of six months.



  The implant has revitalizing and stimulating properties on certain declining metabolisms which allows its use in geriatrics.



  The product became clinically active on rheumatoid arthritis which was confirmed by biological controls carried out in the treated cases, in particular by assays of specific immunoglobins, interleukins, and the study of the blood formula.



  For the manufacture of the product, three raw materials are needed, namely:
 - lyophilized placenta extract of human origin,
 - active collagen of human placental origin in suspension,
 - dry extract of embryonic dental bud of bovine origin.



  The proportions to respect for the implant to be manufactured are:
 - approximately 200 mg of lyophilized placenta extract of human origin, which corresponds to 40 g of placenta in fresh tissue,
 - 0.3 ml of native collagen of human origin corresponding to 1.5 mg of dry extract,
 - 10 mg of dry extract of lyophilized embryonic dental bud (mesenchymal tissue) of bovine origin,



   the whole is dissolved in water for injections, for example water destined for apyro QS gene (sufficient quantity) per ml. Then the mixture is sterilized by sterilizing filtration known per se, and placed in 5 ml bottles. 1 ml of the solution obtained after sterilizing filtration is introduced into each bottle, the quantity of 1 ml containing the quantities of material mentioned above for making an implant. The contents of the vials are freeze-dried by standard methods. The implant is in the form of a tablet placed at the bottom of the bottle. After lyophilization, the bottles are capped and crimped under a sterile atmosphere. Preferably an antiseptic agent is introduced into the mixture before sterilization.
