口腔是一个多种微生物生长的理想场所。它窝藏的微生物极多,但它们的品种是有限的。值得注意的是某些菌种除口腔外在其他地方并未发现。这个特点意味着口腔可能含有能阻止某些细菌的生长的抗菌物质。曾在唾液中查见多种抗菌物质。一些抗特殊微生物的抗菌物质的活性能在其特异的抗体存在时增强。粘蛋白水解酶(溶菌酶) 粘蛋白水解酶是能破坏细菌细胞壁某些成份的一种酶。它主要含有由N乙酰氨基葡萄糖(NAG)与乙酰粘蛋白余基通过1—4键
Oral cavity is an ideal place for a variety of microbial growth. It contains a very large number of microorganisms, but their variety is limited. It is noteworthy that some species have not been found elsewhere except in the oral cavity. This characteristic means that the oral cavity may contain antibacterial substances that prevent the growth of certain bacteria. Have found a variety of anti-bacterial substances in saliva. The activity of some antimicrobial substances against specific microorganisms is enhanced in the presence of their specific antibodies. Mucolytic enzymes (lysozymes) Mucolytic enzymes are enzymes that destroy certain components of the bacterial cell wall. It contains mainly N-acetylglucosamine (NAG) and acetyl mucin residues through the 1-4 bond
