溶菌酶是一种小分子蛋白质,主要分布在人体痰液、唾液、泪腺、尿和血清等处。正常情况尿溶菌酶可被肾近曲小管重吸收,所以尿液的溶菌酶活性极微,当肾脏受损时该酶活性相应改变。唾液中溶菌酶活性的变化,可反应机体非特异性免疫功能状态。 选某化工厂铬酸盐车间(空气浓度为0.004mg/m~3)92名接触铬作业工人,年龄范围19～50岁,工龄1～23年。同时选某研究 Lysozyme is a small molecule protein, mainly in human sputum, saliva, lacrimal gland, urine and serum. Urine lysozyme normal renal tubular proximal reabsorption, so urine lysozyme activity is minimal, when the kidney damage the enzyme activity changes accordingly. Changes in saliva lysozyme activity can reflect the body’s non-specific immune status. Select a chemical plant chromate workshop (air concentration of 0.004mg / m ~ 3) 92 contact chromium workers, the age range of 19 to 50 years of age, length of 1 to 23 years. At the same time choose a research
