Description
Preparation method, sea-mussel mucin gel and its applied technical field of sea-mussel mucin gel
It is that main active prepares the method that wound repair product, protecting wound surface product, old scar dispel product, adhesive product, embedded type reparation product, the moisturizing class cosmetics for increasing skin elasticity, anticorrosion medical coating and industrial coating product the present invention relates to the preparation method of sea-mussel mucin gel-like product, more particularly to using sea-mussel mucin.
Background technology
Sea-mussel mucin（Mussel Adhesive Proteins, MAP) or " mussel byssus protein "（Mytilus Edulis Foot Protein MEFP), it is a kind of polyhydric phenols basic protein derived from marine mussel.Mussel is commonly called as " Hai Hong ", " mussel ", belongs to cool temperature zone, eurysalinity species, in global each marine site with the presence of variety classes, China there are about 50 kinds.It is distributed in the Perna viridis of Perenniporia martius（Perna viridis), be distributed in the Mytilus galloprovincialis in frigid zone and temperate zone（Mytilus edulis) and Trachyostracous mussel（Mytilus coruscus) it is the important cultivation in countries in the world and fished species.Sea-mussel mucin is present in a special body of gland for mussel, the glycosylation modified of complexity, hydroxylating modification and cross-linking reaction is experienced in synthesis, just because of the special the Nomenclature Composition and Structure of Complexes of this albumen so that mussel has extremely special ability.There is L-3,4- dihydroxyphenylalanines in sea-mussel mucin（L-DOPA), L-DOPA residues are cross-linked with each other due to oxidation reaction so that generate strong and lasting splicing in mussel and special surface fiber.Sea-mussel mucin has the advantages that bonding scope is wide, speed is fast, corrosion-resistant, intensity is high and bioaffinity is good, it is considered to be fabulous broad-spectrum biological adhesive and applied to fields such as medical science and bioengineering.Moreover, recent studies suggest that, sea-mussel mucin can effectively facilitate burn, scald skin healing and growth, also have obvious effect to dispelling for outmoded scars.
Sea-mussel mucin generally exists with liquid or freeze-dried powder state, when using by the way of direct smearing or spraying, but during for privileged sites such as position in irregular shape, it is not easy to keep, action effect is uneven.And liquid rate of drying is fast, the action time of sea-mussel mucin is shortened, reduces the effect of sea-mussel mucin.
Gel be by active material and gel-type vehicle be made it is homogeneous, be suspended or emulsion-type latex glop or semisolid preparation, with good biocompatibility, be easy to absorb after local administration, not pollution clothes, stability it is good, enable in particular to produce slow-release controlled-release and pulsed release effect.Gel substrate belongs to single-phase decentralized system, has aqueous point with oiliness, aqueous gel matrix is typically made up of water, glycerine or propane diols and cellulose derivative, carbomer and alginate, tragacanth, gelatin, starch etc.；Oil-base gel matrix is by liquid
Shape paraffin is constituted with polyethylene or fat oil with colloidal silicon or aluminium soap, zinc soap, in recent years the research and development focus as exterior-applied formulation.
In addition, China Patent Publication No.（CN101348520, CN101348518, CN101585874) and PCT international application no（PCT/CN2012/073167 the method for several separating and purifying sea-mussel mucins disclosed in), is hereby incorporated, and belongs to the content that the present invention is recorded.
The content of the invention
It is an object of the invention to provide a kind of preparation method of sea-mussel mucin gel, prepared sea-mussel mucin gel and its application, to solve the defect for being difficult to keep that prior art is directly smeared or spraying is brought using liquid sea-mussel mucin or its fluid product.

1 dissolving sea-mussel mucin dry powder, obtains sea-mussel mucin solution, concentration is 10mg/mL-50mg/mL, and using lemon phosphoric acid-phosphate-buffered buffer solution, pH is 1-9.
The 2 accurate injection waters for weighing 1.2g hydroxypropyl methyl celluloses and 2.5g cation guar gums, adding 50mL, stir, pH to 5-7 is adjusted using sodium hydroxide, add water and supply 100g, 10-100min is placed in 10 °C -80 °C of environment, form gel.
During 3 uses, gel is first coated with, then a certain amount of sea-mussel mucin solution is added in gel surface, final sea-mussel mucin gel is formed.
At the external equipment for taking appropriate this gel coating ship; smear uniform; whole equipment is completely covered; and it is that the thickness of gel reaches l-2mm; the gel can effectively protect the equipment of coating; its corrosive speed is reduced, while the normal operation to equipment does not produce any negative impact.Embodiment 9
1 prepares sea-mussel mucin solution, and concentration is 10mg/mL-60mg/mL, using acetic acid-acetate buffer
Liquid, pH is 1-9.
The 2 accurate injection waters for weighing 0.5g hydroxypropyl methyl celluloses and 2.5g cation guar gums, adding 50mL, stir, and adjusted using triethanolamine and 10-120min is placed in pH to 5-7,10 °C -80 °C of environment, form gel.
3 add the 450mg prepared in Shang Shu Walk rapid 1 sea-mussel mucin into Suo Shu Walk rapid 2, make its final concentration of 4.5mg/g, then uniform mixing, the sea-mussel mucin gel of formation.
4 respectively by 10mL sorbierites, 2mL glycerine, 3mL propane diols, 0.02g chloreresols, 0.2g cysteines, 3g PVP-Is, 0.02g silver iodide, O.OOlg rose essential oils, it is added in sea-mussel mucin gel, then uniform mixing, adds water and supplies 100g, then form final sea-mussel mucin gel.
Take this appropriate gel coating in newborn wound, smear uniform, whole injury is completely covered, a gel was changed again at interval of 8-12 hours.The gel can be very good the wettability for keeping smearing position, give patient more comfortable impression.The presence of sea-mussel mucin can significantly reduce the bleeding of wound, effectively facilitate the healing of wound, the presence of PVP-I and silver iodide plays the role of sterilization to wound simultaneously, and sea-mussel mucin can then reduce excitant of these bactericide to wound skin.Adhere to a course for the treatment of（9 days）, damaged part can be made well to be healed and recovered.Industrial applicability
Sea-mussel mucin gel products prepared by the present invention can play the advantage of sea-mussel mucin and gel simultaneously, and obtained sea-mussel mucin gel is easily kept, effect is lasting, action effect is uniform, long action time, good dispersion, adhesive force is strong, stability is good, it is simple, easy to use to prepare, be readily cleaned.
Certainly; the present invention can also have other various embodiments; in the case of without departing substantially from spirit of the invention and its essence; those skilled in the art can make various corresponding changes and deformation according to the present invention, but these corresponding changes and deformation should all belong to the protection domain of the claims in the present invention.
