The spray of the present invention is prepared by compounding lysostaphin as a main ingredient with a stabilizing agent, a synergist and other effective biological ingredients. The oral composite lysostaphin spray has the advantages of strong bactericidal activity, high stability and incapability of generating drug resistance, and the oral composite lysostaphin spray which is a biotype oral spray has no toxic or side effect.
Description
The present invention relates to biological preparation, be specifically related to a kind of composite lysostaphin enzyme spray for oral cavity and preparation method.
The oral cavity is the important barrier of people's human body with extraneous contact, is an ingredient of respiratory system, digestive system, also is the part that is vulnerable to encroach on most simultaneously, comprises the infringement of air pollution, antibacterial etc.Along with the air-polluting aggravation, the deterioration of environment, the incidence rate of oral disease has improved greatly.
There are numerous pathogenic bacterium in the oral cavity, wherein account for comprising of main ratio: antibacterials such as staphylococcus, Hemolytic streptococcus, Candida albicans, anaerobe.They are the root of oral disease still not, but also influence the normal absorption of nutrition even can cause that such as respiratory tract therefore the disease of organs such as gastrointestinal prevents and kill oral cavity pathogen, to safeguarding human oral cavity health, the sickness rate that reduces other organ is very crucial.
For a long time, the oral cavity treatment of diseases is adopted chemistry, antibiotics always, although played a role at that time, along with the use repeatedly of these medicines, brought a series of adverse effect---produced many drug-fast strains, brought toxic and side effects to human body.Endurance strain shared ratio in pathogenic bacterium has the gesture of rising year by year now.
Antibiotic is to work in the metabolic process of bacterial growth, can only play the purpose of bacteria growing inhibiting, and it all can not be killed, and the antibacterial that a part is survived will have the antibiotic resistance of this kind.
Used cleaning agent for mouth cavity mainly contains four kinds of compositions: ethanol, wetting agent, surfactant and essence.In order to prevent halitosis, most sprays are allocated antibacterial into, and it is mainly metronidazole, hibitane and some Chinese medicine such as SHUANGHUANLIAN etc.Can reach fungistatic effect preferably though add antibacterial, because the very easy generation fastbacteria of chemical drugs also has stimulation to oral mucosa, Cuo is very big to gastric irritation as first nitre, is difficult for being accepted by the people.
In the oral cavity infection treatment of diseases, present stage is still based on chemistry and antibiotics.For example, old people oral cavity candidiasis is mainly used nystatin and cydiodine, acute pericoronitis first nitre Cuo, and oral lichen planus waits with first nitre Cuo and tetracycline and treats, and these medicines are toxic side effect all, but also the bacterial strain that can develop immunity to drugs.Also do not have a kind of real effectively full biological preparation at present, can effectively sterilize and without any side effects, but also be difficult for developing immunity to drugs.
The objective of the invention is to overcome above-mentioned shortcoming, develop a kind of having no side effect, be difficult for producing drug resistance, efficient, broad-spectrum bactericidal biotype cleaning agent for mouth cavity.
The invention provides a kind of composite lysostaphin enzyme spray for oral cavity, this spray is formed (percentage by weight) by following composition:
Main component: 1. staphylococcus lysozyme (lysostaphin) 1-3%
2. lysozyme (lysozyme) 10-20%
Adjuvant: 3. sorbitol (sorbic alcohol) 6-7%
4. potassium phosphate (potassium phosphate) 7-10%
5. sodium chloride (sodium chloride) 0.5-1%
6. essence (essence) 0.1%
7. bacitracin (bacitracin) 2-3%
8. distilled water (distilled water) 60-70%
The sterilizing mechanisms of oral spray of the present invention is as follows:
Staphylococcus lysozyme is a kind of bacteriolysin of gram positive bacteria.Form the aminoacid of the tetrapeptide side chain of such gram positive bacteria (for example staphylococcus aureus) whole cell peptidoglycan, be followed successively by the L-alanine, D-glutamic acid, L-lysine, D-alanine; And the first L-alanine links to each other with 3-O-.alpha.-carboxyethyl-D-glucosamine. by an amido link, and the L-lysine that this polysaccharide chains tetrapeptide side chain is the 3rd is attached on the adjacent polysaccharide chains tetrapeptide side chain D-alanine carboxyl by pentapeptide (five glycine) cross-bridge.Intersect in length and breadth thus, about connect and constitute very tough and tensile 3 D stereo loose structure, and aggregate into thicker Peptidoglycan layer.Staphylococcus lysozyme can cut off the Gly-Gly key in the Peptidoglycan, and another kind of enzyme can cut off key between-acetylmuramic acid and the N-acetylglucosamine in the molten Portugal coccus compound enzyme, thereby make bactericidal activity stronger, reach the purpose of dissolving and killing bacteria, and can avoid the generation of bacterial drug resistance.
Because the sterilization mechanism of staphylococcus lysozyme uniqueness makes it be different from general antibiotic.Except that producing beta-lactamase, also there is other resistance mechanism in the resistance mechanism complexity of drug resistance staphylococcus aureus.To antibacterials commonly used, more Resistant strain is also arranged according to clinical observation MRSA as penicillin, benzylpencilline one, third generation cephalosporin class antibiotic and some Novel Quinolone antibacterials.From above-mentioned situation; though new antibiotic is arranged constantly to be developed and comes into operation; produce but just have new Resistant strain in very short time, this is because most of antibiotics bacteria growing inhibiting impels the R-plasmid of Production by Bacteria tissue regeneration promoting or the effect that new enzyme stops antibiotics.The mechanism of action of staphylococcus lysozyme is different from general antibiotic, and antibiotic effect only is a bacteria growing inhibiting, and this enzyme then is a cracking antibacterial killing bacteria, and the staphylococcus aureus of methicillin-resistance (MRSA) is had stronger sterilizing ability equally.
Staphylococcus lysozyme can produce bacteriolysis by hydrolysis gram-positive bacterium whole cell peptidoglycan, thereby thorough killing bacteria has been avoided the generation of bacterial drug resistance.The antibacterial of strain more than 400 that units such as the Huashan, Shanghai City hospital institute of Antibiotics, The 2nd Army Medical College Changhai hospital laboratory, Shanghai City Sixth People's Hospital clinical laboratory, Shanghai City the 9th the People's Hospital clinical laboratory once collected clinical each section has carried out the sterilization experiment that presses down of staphylococcus lysozyme.Experimental result shows: staphylococcus lysozyme is to gram positive bacteria, as common clinically staphylococcus aureus, staphylococcus epidermidis, Diplococcus pneumoniae, D group enterococcus, tetracoccus, product monokaryon Listerella, streptococcus and stomach Helicobacter pylori etc. all have tangible inhibitory or killing effect.
Experiment also proves staphylococcus lysozyme to endurance strain, and as feeling most thorny methicillin-resistant staphylococcus aureus on the present clinical medicine, drug resistance Diplococcus pneumoniae, the effect of having a liking for the narrow food sporangium of Fructus Hordei Germinatus more are better than common antibiotics.
Oral spray of the present invention can be efficiently presses down cells such as the staphylococcus aureus that causes pharyngolaryngitis, tonsillitis, oral ulcer, gingivitis, periodontitis, pericoronitis, papillary gingivitis extremely, Hemolytic streptococcus, streptococcus pneumoniae, colibacillus, Candida albicans, fungus, anaerobe, sterilizing rate 99.9%.Have no side effect, non-stimulated to mucosa.
