唾液中溶菌酶是机体的一种非特异免疫因子,其含量的变化在一定程度上可说明机体非特异性抵抗力状况。由于该指标较灵敏、测定方法简便、能用于现场调查,故已被广泛用作评价大气污染对人体免疫功能影响的一项指标。各地报导的溶菌酶含量值变异范围相差很大,统计方法各异(见表2),这给相互比较、确定正常值范围等造成了困难。为此,我们对正常人唾液中溶菌酶的变化规律、测定中的某些影响因素、唾液溶菌酶含量的频数分布等问题进行了初步探讨,现将结果报告如下。
Salivary lysozyme is a non-specific immune factors, the changes in its content to some extent, explain the body’s non-specific resistance status. Because of the sensitivity of the indicator, the determination method is simple and can be used for field investigation, it has been widely used as an indicator to evaluate the impact of air pollution on human immune function. The range of variation in lysozyme content reported varies widely from country to country, with different statistical methods (see Table 2), which makes it difficult to compare each other and determine the normal range. Therefore, we conducted a preliminary study on the changes of lysozyme in normal saliva, the determination of some influencing factors, the frequency distribution of salivary lysozyme content, and the results are reported as follows.
