Description
Technical field
The present invention relates to a kind of biotype biocide preparation, specifically, relate to a kind of biological preparation that is used for suppressing and killing helicobacter pylori and its production and application.
Background technology
From people's gastric mucosa, be separated to helicobacter pylori (Helicobacter pylori from 82 years by Australian scholar Warren and Marshall, Hp) (Marshall BJ, Royce A, Annear DI, et al.Original isolation of Camylobacter pyloridis from human gastric mucos.Microbios Letters.1984,25:83-84), existing a large amount of research datas show, Hp is the pathogen of chronic active gastritis, it is the important virulence factor of peptic ulcer, also be the lymphadenomatous important virulence factor of gastric mucosa-associated lymphoid tissue, and have report to think Hp and gastric cancer, stomach, 32 kinds of disease relationships such as duodenal ulcer are close.Hp is published as new infectious disease by WHO at present.
In developed country, the Hp crowd infection rate is about 50%, and developing country's childhood infection rate is just up to 50%, and adult's infection rate can be up to more than 90%.Hp can discharge from feces, saliva, and the people is this sick source of infection, and sheep, monkey, pig, cat, Canis familiaris L. etc. also are the hosts of Hp.Existing Epidemiological study data shows that the propagation of Hp mainly contains dual mode: (1) is through the iatrogenic infection of gastroscope; (2) interpersonal contact is closely propagated with mouth a bite, stomach a bite or excrement a bite approach, obviously has clustering of disease in family.Existing document announcement, Hp positive person spouse's infection rate (78.9%) is apparently higher than Hp negative patient spouse's infection rate (26.6%); The two male childhood infection rates (89.74%) of father and mother Hp are apparently higher than the childhood infection rate (16.68%) of father and mother Hp jack to jack adapter.In the risk factor that Hp infects, except that heredity, environment and hygienic habit such as shared food are chewed feeding,
Food pollution, the brush etc. of seldom growing permanent teeth, living conditions, economy and education, nutrition etc. all play an important role.Particularly the effect of oral hygiene in Hp infects caused concern, thinks that dental plaque is the breeding place of Hp, and oral environment may be the propagation ducts of Hp; And think that the Hp in the oral cavity may be the important storage vault that stomach Hp infects again, the radical cure of Hp also should comprise the removing to Hp in the tooth bacterium class.Shanghai City Center for Disease Control (CDC) 2000 shows that to family domestic contamination investigation surplus the whole city 200 the home environment severe contamination accounts for 22.8%, and its toothbrush severe contamination rate is 50.5%, and the Hp positive rate is 5.9%.
Present treatment multiselect antibiotic to helicobacter pylori.But the life-time service antibiotic can cause body and produce various untoward reaction, react as GI irritation.And the life-time service antibiotic causes that easily antibacterial produces drug resistance to it.Test shows that external, Hp is to vancomycin (Vanoomycin) and TMP (trimethoxy ammonia benzyl pyrimidine) height drug resistance.And many at external antibacterials to Hp hypersensitivity poor efficiency or invalid in vivo, as erythromycin, spiramycin etc.In recent years because antibiotic therapies such as extensive use metronidazole, clarithromycin clinically are therefore, comparatively common to the Resistant strain of these medicines.
Reported in the document metronidazole and the drug-fast bacterial strain of clarithromycin (Boron, et al.Helicobacter pylori binds to blood group antigens.Scientific Amer.Scienve ﹠amp; Med.1:28-37).
Chinese medicine is smaller to the toxic and side effects of body, also be difficult for producing drug resistance, but the sterilizing ability of Chinese medicine is not strong, and needs long-time the use just to take effect, and makes troubles to the patient.
Therefore, develop and a kind ofly can efficiently kill helicobacter pylori, little to the body zest again, the little and helicobacter pylori of toxic and side effects is difficult for producing chemical sproof preparation to it, becomes the task of top priority.
