Purpose of the present invention then is the obvious deficiency at above-mentioned existing chemicals and Chinese medicine preparation, and providing a kind of is the biological product class oral buccal tablet of primary raw material with the epidermal growth factor.
Technical solution of the present invention:
Epidermal growth factor (Epidermal Growth Factor, abbreviation EGF) single chain polypeptide of forming by 53 amino acid residues, contain three pairs of disulfide bond in the molecule, molecular weight is 6KD, be a kind of important somatomedin of human endocrine, denier can promote the division and the growth of epidermis cell strongly.The biological effect of EGF comprises:
1. significantly promote the growth and breeding of epithelial tissue cell;
2. chemotaxis: in the process of wound repair, EGF has chemotaxis to inflammatory cell, fibroblast, epidermis cell, vascular endothelial cell, and it is moved to wound site, and division and proliferation quickens wound repair, also plays antiinflammation simultaneously;
3. strengthen intercellular substance albumen synthesis capability, make the collagen fiber linear arrangement;
4. promote that low molecular weight compound initiatively is transported to from the extracellular in the cell, to increase the nutrient substance of cell;
5. the activation glycolysis is to increase respiratory metabolism, activating phosphatase fructokinase;
6. promote new vessels formation and nucleic acid, proteinic synthetic, thereby by synthesizing of matter between the hamartoplasia important cells promoting all kinds of wound healings.
These biological effects show that epidermal growth factor can pass through conducted signal, cause that a series of biochemistrys change in the cell, start the gene relevant with cell division, make akinete enter cell division cycle, thereby make cell proliferation.The chemotaxis of EGF also has the antiinflammatory bacteriostasis efficacy to wound surface simultaneously.
