RON force has successfully developed new enzyme toothpaste

Recently, a glucanase and lysozyme by two kinds of enzyme complex preparation for enzyme toothpaste lung power in tsinghua university's institute of biotechnology development success. Lung power of this new type of enzyme toothpaste has the prevention of dental caries, remove plaque, removal of oral bacteria and other special effects. According to the WWW. hzpzs。 Net of small make up to know, in oral disease, usually caused by dental caries and periodontal disease is the leading cause of missing. According to modern caries epidemiology thinks, the occurrence of this disease is mainly due to bacterial fermentation of sugar to produce acid, cause tooth hard tissue caused by demineralization. In the human body in the mouth, the extracellular polysaccharide substance, especially water insoluble glucan, it can promote the bacteria adhesion on tooth surface, the bacteria gathered together, this will accelerate the formation of plaque. At the same time, the extracellular polysaccharide to participate in the formation of plaque matrix, accounts for more than a third of plaque matrix composition, mainly glucan in the polysaccharides. Glucan is water insoluble, its stronger adhesion high aggregation and biological stability, and not easy to degradation, both have the effect of binder in the plaque, glucan bacterial adhesion to tooth surface, have played an important role skeleton, consolidate the matrix structure of plaque. And glucanase can form sticky polysaccharide material degradation bacteria in the mouth, eliminate bacteria survival condition, inhibition of bacterial adhesion to tooth enamel surfaces, to prevent caries ready-made, achieve the goal of prevention and control. And lysozyme is saliva important antimicrobial properties, it is widely distributed in the body's tissues and external secretion and circulating cells, is considered to be the host of immune defense against bacteria in important component. Lysozyme in oral environment steady balance adjustment, is closely related to the occurrence of oral disease development. Lysozyme is a kind of cationic protein, it has antiseptic, bacteriostatic, aggregation, adhesion lysis, bacteria and prevent bacterial metabolism, regulate the formation of plaque, reduce the formation of acid in dental plaque inside, prevent caries. www。 hzpzs。 Net editor: xiao sun editor: note: henan
