Description
The invention belongs to the medicinal preparation technical field, relate to a kind of bone growth factor injection of from the natural animal bone material, extracting and preparation method thereof.
At Osteopathic Medicine circle, traditional bone conduction theory is subjected to bone in recent years and induces theoretical impact.Orthopaedic diseases such as, bone does not connect damaged with skeletal growth factor treatment fracture, bone are the very active both at home and abroad research topics of competitively carrying out.A large amount of research reports is verified, bone morphogenetic protein BONE MORPHONETIC PROTEIN (hereinafter to be referred as BMP) but bone that the mesenchymal cell that moves about around the induction of vascular is converted into irreversibility is born of the same parents, thereby can produce cartilage and osseous tissue in the position beyond skeleton or skeleton, this mechanism is generally acknowledged by domestic and international Osteopathic Medicine circle.In the domestic and international prior art before the present invention, with the research work of every induced osteogenesis on basis, BMP position carry out a lot, for example: to the research of bone morphogenetic protein (BMP) immunity principle and regulatory function; Experimentation to endogenous BMP and guided bone regeneration; Multiple to BMP and other factor and use research; The research of gene recombinaton BMP; Carrier is to research of BMP activity influence or the like.Existing experiment showed, that the partially purified BMP of natural extract has good bone-inducting active, contain the bone-inducting active height of the BMP of several molecular weight, but when cost height, manufacturing cost, can not satisfy the demand than the purification unimodal molecular weight.The active relation of carrier and BMP is an inevitable problem in the experimentation of BMP and the clinical practice, because the content of BMP in bone seldom, extracted amount is limited, uses the BMP of high purification that the danger of being taken away by local body fluid is arranged again.Therefore, the application of BMP must consider to adopt the problem of which kind of optimum carrier simultaneously.Carrier commonly used in the prior art has decalcified bone matrix (DBM), porous calcium phosphate (TCP), hydroxyapatite (HAP), bioactivity glass magnetic and fibrin paste etc., but all there is such or such problem more or less in these carriers.In sum, though in recent years, formed climax based on the research of the bone induced osteogenesis of BMP, some work also has innovation very much, up to now, belongs to very sophisticated, to can be used in clinical BMP medicinal preparation actually rare.Induce in the different another kind of prior aries of mechanism with above-mentioned bone, Chinese CN89105016.7 patent disclosure a kind of " cell growth stimulant and manufacture method thereof ".Main component in this medicine is aseptic plasma-coagulase, and contains protein, polypeptide and several amino acids, is the extracting solution of thanking to the golden staphylococci metabolite that pig myocardium peptone and sodium-chloride water solution are made training oxygen base.This injection that impels union of fracture and treatment ulcer, what emphasize on the mechanism of curing the disease is the synergism of multiple bioactive substance, do not need to consider effective ingredient or the effective site mechanism of action and separation problem, therefore, this medicine consumption in actual use is also very big, need carry out just produce effects fruit of multiple injection.At present, this medicine several years that appeared on the market, but so far its medical mechanism and actual efficacy are not had clear and definite saying.Induce skeletal growth factor treatment mechanism under the theoretical direction that difference on the level is arranged with above-mentioned bone.
At above-mentioned prior art situation, the objective of the invention is to: provide a kind of and have based on the compound skeletal growth factor of the partially purified BMP of natural extract and have the injection type medicinal preparation and the preparation method of the best sensitization carrier of effective slow releasing function.And make every effort to make that its effect is remarkable, expense is few, be easy to preserve, easy to use.
Now design of the present invention and technical solution are described below:
Induced osteogenesis theory based on BMP is thought: induced osteogenesis must possess three conditions, that is: (1) induces stimulus object (as skeletal growth factor); (2) mesenchymal cell; (3) be beneficial to the blood supply environment of osteogenesis.The present invention to the associating topical application of bone morphogenetic protein (BMP) with angiogenesis factor (FGF), has done deep research on the basis of a large amount of experiments.Experimental result confirms, except bone morphogenetic protein (BMP) but the bone that the mesenchymal cell that moves about is converted into irreversibility around the induction of vascular is born of the same parents, the position produces outside cartilage and the osseous tissue beyond skeleton or skeleton, alkalescence becomes cell fibroblast growth factor (FGF), there is the chondrocyte of stimulation to increase the matter effect, be a kind of powerful capillary proliferation stimulant, and the formation of endochondral ossification and blood capillary is the important step behind the bone induced osteogenesis.Experiment is proof also, polyethylene pyrrolinone (PVP) has the good adsorption effect to the protein high molecular material, to skeletal growth factor---the sensitization that is bone morphogenetic protein and fibroblast growth factor is fairly obvious, and it is fine with the intermiscibility of the two, can form suspension completely, be a kind of effective slow-released carrier.In view of the above, the present invention at first provides a kind of osteogenesis stimulin medicinal preparation, it is characterized in that: the exogenous skeletal growth factor and the carrier that contain more than one; Exogenous skeletal growth factor is Bovine Bone Morphoge Protnetin (b BMP) or human bone morphogenesis protein (hBMP) and fibroblast growth factor (bFGF) or gene recombinaton human fibroblastic growth factor; The sensitization carrier is polyethylene pyrrolinone (PVP); Exogenous skeletal growth factor Bovine Bone Morphoge Protnetin (b BMP) or human bone morphogenesis protein (hBMP) are 3: 10 with the weight ratio of sensitization carrier polyethylene pyrrolinone (PVP); Under this conditions of mixture ratios, need to add the fibroblast growth factor (bFGF) or the gene recombinaton human fibroblastic growth factor of 80000IU unit.Secondly, the present invention also provides the preparation method of osteogenesis stimulin injection, it is characterized in that, the preparation process of this preparation is:
