Description
COMPOSITION DE NACRE DESTINEE A CORRIGER DES DEFAUTS DE NIDATION CHEZ LES MAMMIFERES. NACRE COMPOSITION FOR CORRECTING NAMING FAULTS IN MAMMALS.
La présente invention concerne une composition de particules de nacre de coquilles de bivalves pour une utilisation destinée à corriger des défauts de nidation chez les mammifères. On sait qu'il existe 80 millions de cas d'infertilité soit 1 couple sur 7, intéressant 30 à 40 % de femmes. Des méthodes ont été développées visant à corriger l'absence de fécondation naturelle. C'est le cas pour l'insémination artificielle ; la plus ancienne des techniques de procréation assistée qui consiste à déposer le sperme directement dans les voies génitales : infra-vaginale, intra-cervicale ou intra-utérine. Les autres techniques de procréation médicalement assistée sont la fécondation in vitro (FIV), la fécondation par micro-injection intra-cytoplasmique de sperme ou ICSI qui consiste en l'injection directement dans l'ovule d'un seul spermatozoïde présélectionné. Toutefois, le taux de réussite reste de 23% pour les FIV et de 25% pour les ICSI. Les échecs trouvent leurs explications aussi bien chez l'homme que chez la femme et sont attribués à diverses causes, hormonales, anatomiques, infectieuses, génétiques ou autres, mais il reste 15% d'échecs inexpliqués. Chez les équidés, les bovins, les ovins, les porcins, le problème de la reproduction à des fins génétiques et économiques ou de conservation d'espèces se heurte à des échecs, comme chez l'humain. C'est ainsi que 40% des juments inséminées avortent pour des raisons multiples et que 15 à 20% des inséminations chez les bovins se soldent par des échecs. Outre les problèmes purement hormonaux, anatomiques ou infectieux, les échecs aussi bien chez l'humain que chez l'animal tiennent également à des défauts de nidation. Dans tous les cas, ces défauts de nidation viennent souvent du fait que l'environnement de l'endomètre utérin ne constitue pas un milieu permissif à la nidation. On sait que chez la femme des troubles trophiques sont responsables de la faible épaisseur de l'endomètre, ce qui compromet la nidation et la poursuite à terme d'une grossesse. The present invention relates to a composition of mother-of-pearl particles of bivalve shells for use in correcting implantation defects in mammals. We know that there are 80 million cases of infertility is 1 couple out of 7, interesting 30 to 40% of women. Methods have been developed to correct the lack of natural fertilization. This is the case for artificial insemination; the oldest assisted procreation technique which consists of depositing sperm directly into the genital tract: infra-vaginal, intracervical or intrauterine. Other medically assisted procreation techniques are in vitro fertilization (IVF), fertilization by intracytoplasmic microinjection of sperm or ICSI which consists of the injection directly into the egg of a single preselected spermatozoon. However, the success rate remains 23% for IVF and 25% for ICSI. The failures are explained by both men and women, and are attributed to various causes, hormonal, anatomical, infectious, genetic or otherwise, but 15% unexplained failures. In equines, cattle, sheep, pigs, the problem of breeding for genetic and economic or conservation of species faces failures, as in humans. Thus, 40% of inseminated mares abort for multiple reasons and 15 to 20% of inseminations in cattle fail. In addition to purely hormonal, anatomical or infectious problems, failures in both humans and animals are also due to implantation defects. In all cases, these implantation defects often come from the fact that the environment of the uterine endometrium does not constitute a permissive medium for implantation. It is known that in women trophic disorders are responsible for the small thickness of the endometrium, which compromises implantation and continuation of a pregnancy.
Il en est de même chez les équidés et les bovidés où un endomètre de faible épaisseur, présentant des troubles trophiques est responsable des échecs à la nidation dans 20% des cas. De même que d'autres pathologies spécifiques telles les endométrites, les dystocies, l'absence ou l'insuffisance d'involution utérine sont responsables de l'infertilité en modifiant physiologiquement l'endomètre. Enfin, un phénomène propre aux équidés peut compromettre non seulement la fécondation mais encore la nidation car il intervient immédiatement lors de la saillie ou de l'insémination : c'est la réaction inflammatoire physiologique consécutive au dépôt du sperme sur l'endomètre avec libération de prostaglandines engendrant une altération du mécanisme des défenses utérines, qui crée ainsi un mauvais environnement à la nidation temporaire ou définitive. Bien entendu, tous ces échecs qui, d'une part, sont psychologiquement difficiles à surmonter chez l'humain, ont, chez l'animal, un coût lié aussi bien au prix du matériel d'insémination qu'à celui des traitements nécessaires pour corriger les désordres anatomiques et physiologiques, et également lié au coût du sperme du donneur pour peu que ce dernier soit un animal de valeur. Ainsi, il existe un réel besoin pour des compositions capables d'améliorer les conditions de la nidation chez les mammifères. Les présents inventeurs ont trouvé que l'amélioration des conditions de nidation 20 chez les mammifères pouvait être obtenue grâce à une composition contenant de la nacre de coquille de bivalves. Ainsi, l'invention a pour objet une composition qui comprend de la nacre de coquille de bivalves pour une utilisation dans une méthode de traitement des défauts de nidation chez les mammifères. 25 Une telle composition permet d'optimiser les conditions locales favorisant et stimulant la nidation de l'oeuf, notamment en améliorant la vascularisation et la tonicité de l'endomètre. La nacre mise en oeuvre dans les compositions de la présente invention est issue de coquille de bivalves choisis dans le groupe comprenant la Pinctada Maxima, la 30 Pinctada margaritifera et autres Pinctadines, le Tridacnae Gigas, et leurs mélanges. On peut mettre en oeuvre dans les compositions de l'invention de la nacre micronisée, c'est-à-dire présentant un diamètre moyen en volume de 1 à 200 microns, de préférence de 5 à 100 microns et plus préférentiellement encore de 10 à 50 microns. On peut également utiliser de la nanonacre, c'est-à-dire de la nacre ayant un diamètre moyen en volume inférieur à 500 nm, de préférence inférieur à 250 nm, et plus préférentiellement encore inférieur à 100 nm. Le diamètre moyen équivalent en volume des poudres est déterminé par diffraction laser à l'aide d'un granulomètre laser. A partir de la répartition granulométrique mesurée dans une large gamme, le diamètre moyen équivalent en volume ou D(4 ;3) est calculé selon la formule suivante D(4 ;3)= E(d4)/E(d3) On peut également utiliser dans la composition de l'invention de la nacre mécanostructurée obtenue par mécanosynthèse à une température inférieure à 60°C, de préférence inférieure à 40°C, et plus préférentiellement encore inférieure à 20°C, dont les particules présentent un diamètre moyen en volume inférieur à 500 nm, de préférence inférieur à 250 nm et plus préférentiellement encore inférieur à 100 nm. Une telle nacre mécanostructurée est décrite dans la demande de brevet FR 09 54066. En particulier, selon un mode de réalisation de ce procédé, le test nacré est broyé à environ 20 microns et placé dans un broyeur planétaire pouvant atteindre des vitesses de rotation de 1100 tr/mn pour des accélérations de 95G dans lesquels des bols en zirconium contenant des billes en zirconium de diamètres variables de 20 à 5 mm.

Elle est destinée à une application topique vaginale et/ou utérine. It is the same in equines and cattle where a thin endometrium with trophic disorders is responsible for failure to nest in 20% of cases. As well as other specific pathologies such as endometritis, dystocia, absence or insufficiency of uterine involution are responsible for infertility by physiologically modifying the endometrium. Finally, a phenomenon specific to equidae can compromise not only fertilization but also implantation because it occurs immediately during the protrusion or the insemination: it is the physiological inflammatory reaction following the deposit of the sperm on the endometrium with release of Prostaglandins causing an alteration of the mechanism of the uterine defenses, which creates a bad environment for temporary or permanent implantation. Of course, all these failures which, on the one hand, are psychologically difficult to overcome in humans, have in the animal, a cost linked as well to the price of the insemination equipment as to that of the treatments necessary for correcting the anatomical and physiological disorders, and also related to the cost of the sperm of the donor if the latter is a valuable animal. Thus, there is a real need for compositions capable of improving the conditions of implantation in mammals. The present inventors have found that improvement of nesting conditions in mammals can be achieved by a composition containing bivalve shell mother-of-pearl. Thus, the subject of the invention is a composition which comprises mother-of-pearl shell for use in a method of treating implantation defects in mammals. Such a composition makes it possible to optimize the local conditions favoring and stimulating the implantation of the egg, in particular by improving the vascularization and tonicity of the endometrium. The mother-of-pearl used in the compositions of the present invention is derived from bivalve shells selected from the group consisting of Pinctada Maxima, Pinctada margaritifera and other Pinctadines, Tridacnae Gigas, and mixtures thereof. It is possible to use in the compositions of the invention micronized mother-of-pearl, that is to say having a volume average diameter of 1 to 200 microns, preferably of 5 to 100 microns and even more preferably of 10 to 50 microns. It is also possible to use nanoseconds, that is to say nacre having a volume average diameter of less than 500 nm, preferably less than 250 nm, and even more preferably less than 100 nm. The volume equivalent mean diameter of the powders is determined by laser diffraction using a laser granulometer. From the particle size distribution measured over a wide range, the volume equivalent mean diameter or D (4; 3) is calculated according to the following formula D (4; 3) = E (d4) / E (d3). use in the composition of the invention of the mechanostructured mother-of-pearl obtained by mechanosynthesis at a temperature below 60 ° C., preferably below 40 ° C., and more preferably still below 20 ° C., the particles of which have a mean diameter of volume less than 500 nm, preferably less than 250 nm and more preferably still less than 100 nm. Such a mechanostructured mother-of-pearl is described in the patent application FR 09 54066. In particular, according to one embodiment of this method, the pearlescent test is milled to about 20 microns and placed in a planetary mill capable of reaching rotation speeds of 1100. rpm for accelerations of 95G in which zirconium bowls containing zirconium beads of varying diameters from 20 to 5 mm. The assembly is subjected to grinding and refrigeration sequences at 18 ° C. of fixed duration. According to an advantageous embodiment, the composition of the invention comprises mother-of-pearl chosen from the group comprising micronized mother-of-pearl, nanonacre, mechanostructured mother-of-pearl and their mixtures.

EXEMPLES Dans les exemples suivants, la nacre mécanostructurée a été obtenue par le procédé décrit dans l'exemple 2 de la demande de brevet FR 09 54066. Exemple 1 On prépare un soluté concentré à 1% dont la composition pour 1 litre est la suivante : - nacre à 1 à 5 microns 1,5 gr - nacre mécanostructurée 0,5 gr - xanthane 1 gr - soluté isotonique qsp pour 1 litre Le soluté peut contenir également des substances antibiotiques, des astringents ou autres molécules potentialisatrices telles que des huiles essentielles. Exemple 2 Dans un broyeur planétaire, on broie un mélange de 2 g de nacre et 0,3 g de chitosan, par diverses séquences interrompues par des phases de refroidissement jusqu'à l'obtention de particules de biomatériau nacre/chitosan de diamètre moyen en volume compris entre 1 à 10 m. Avec ce biomatériau, on prépare un gel dont la composition est la suivante : - biomatériau nacre/chitosan 2,3 gr - Salvia officinalis (extrait) 0,001 ml - gélifiant et eau déminéralisée qsp pour 20 cc De nombreuses autres substances telles que des antibiotiques, des hormones, des antalgiques, des astringents, des protéines végétales texturantes ainsi que d'autres gélifiants ayant des propriétés visco-élastiques peuvent être ajoutés au produit selon l'invention. Exemple 3 On a préparé un ovule à délitement progressif par la température utérine dont la composition est : - nacre mécanostructurée 1 gr - Salvia officinalis (extrait) 0,001ml - excipient phase grasse (glycérides) qsp 3 gr La présence d'extrait de Salvia officinalis s'explique par son action folliculinelike, en effet, cette substance sensibilise la muqueuse utérine à l'action de la lutéïne, hormone de la nidation, qui joue un rôle dans la transformation et la prolifération de l'endomètre, ce qui favorise la nidation. Exemple 4 Le produit selon l'invention a fait l'objet d'une expérimentation sur une jument inféconde depuis 8 ans, du fait d'un déficit implantatoire dû à un environnement non permissif de l'endomètre. Le protocole suivant a été mis en place avant une insémination artificielle. La veille de l'intervention, une douche utéro-vaginale est réalisée à l'aide d'un cathéter prévu à cet effet, avec une poche de soluté selon l'exemple 1 d'une contenance 10 d' l litre. Le liquide est siphonné au bout de 5 mn. Le jour de l'intervention, 20 cc de gel selon l'exemple 2 sont introduits dans la cavité utérine immédiatement avant l'insémination. L'insémination a été effectuée normalement. L'oeuf fécondé s'est implanté à la première tentative avec un développement 15 satisfaisant de l'embryon aboutissant à une gestation et un poulinage normaux. EXAMPLES In the following examples, the mechanostructured mother-of-pearl was obtained by the process described in Example 2 of the patent application FR 09 54066. EXAMPLE 1 A 1% concentrated solute is prepared, the composition of which for 1 liter is the following: - mother of pearl 1 to 5 microns 1.5 gr - mechanostructured mother of pearl 0.5 gr - xanthan 1 gr - isotonic solute qsp for 1 liter The solute may also contain antibiotic substances, astringents or other potentiating molecules such as essential oils. EXAMPLE 2 In a planetary mill, a mixture of 2 g of mother-of-pearl and 0.3 g of chitosan is ground by various sequences interrupted by cooling phases until obtaining mother-of-pearl / chitosan biomaterial particles having a mean diameter of volume between 1 to 10 m. With this biomaterial, a gel is prepared whose composition is as follows: - biomaterial mother-of-pearl / chitosan 2.3 gr - Salvia officinalis (extract) 0.001 ml - gelling agent and demineralised water qsp for 20 cc Many other substances such as antibiotics, hormones, analgesics, astringents, texturizing vegetable proteins and other gelling agents with viscoelastic properties can be added to the product according to the invention. EXAMPLE 3 An ovule with progressive disintegration by the uterine temperature, the composition of which was: - mechanostructured mother-of-pearl 1 gr - Salvia officinalis (extract) 0.001ml - excipient fatty phase (glycerides) qsp 3 gr The presence of Salvia officinalis extract is explained by its folliculinelike action, indeed, this substance sensitizes the uterine lining to the action of lutein, hormone implantation, which plays a role in the transformation and proliferation of the endometrium, which promotes implantation . EXAMPLE 4 The product according to the invention has been the subject of an experiment on an infertile mare for 8 years, because of an implant deficit due to a non-permissive environment of the endometrium. The following protocol was implemented before artificial insemination. The day before the operation, a utero-vaginal shower is performed using a catheter provided for this purpose, with a solute bag according to Example 1 with a capacity of 1 liter. The liquid is siphoned after 5 minutes. On the day of the procedure, 20 cc of gel according to Example 2 are introduced into the uterine cavity immediately before insemination. Insemination was done normally. The fertilized egg was implanted at the first attempt with a satisfactory development of the embryo resulting in normal gestation and foaling.
