无机锰盐在工农业中常用,但在一定浓度下会引发中枢神经系统损害,循环系统障碍,刺激呼吸道和胃肠道,还具有免疫抑制活性.体内实验表明,重金属盐既可刺激也可抑制抗体的生成.作者检查了20名锰厂工人,工龄1～13年,其中半数为女性.厂房空气中锰盐气溶胶浓度在2～10mg/m~3.工人的补体滴度为log_23～7,其中3年工龄者的滴度较高,均在log_25以上.半数工人的血清Ig浓度高于对照组(15名检查仪表车间工人),主要
Inorganic manganese salt commonly used in agriculture and industry, but at a certain concentration will cause damage to the central nervous system, circulatory system disorders, respiratory and gastrointestinal stimulation, also has immunosuppressive activity in vivo experiments show that heavy metal salts can both stimulate and inhibit Antibody production The authors examined 20 manganese factory workers, working for 1 to 13 years, of which half were women.The concentration of manganese aerosol in the plant air was between 2 and 10 mg / m 3 .The complement titer of workers was log 23 to 7 , Among them, the titers of 3-year-old workers were higher than those of log-25.The serum Ig concentrations of half of the workers were higher than that of the control group (15 inspection meter workshop workers), mainly
