摘要
目的观察力德希口服液对涉铅作业工人的保护作用。方法 320例涉铅作业工人分层随机均分为牛奶组(A组)、营养素组(B组)、营养排铅组(C组)和对照组(D组),分别给予牛奶、21金维他片、力德希口服液和饮用水干预,每天1次,连续服用1 a,观察干预前后一般观察指标和健康评价指标的变化。结果 320名受试者干预后的平均血铅水平由330.3降到293.3μg/L,平均血红蛋白含量由124.5升高到127.5 g/L,与干预前相比差异均有统计学意义(P<0.05);与D组相比较,A、B和C组的症状均有不同程度的改善,年度生病总次数和总病假天数也减少,变化程度C>B>A组。结论力德希口服液对涉铅作业工人具有明显的保护作用。
[Objective]To observe the protective effect of Lidexi Oral Liquid on lead-exposed workers.[Methods]320 lead-exposed workers were randomly divided into the milk group(group A),the nutrients group(group B),the lead-excretion group(group C) and the control group(group D) by stratified sampling,which were given milk,21 Super-vita tablets,Lidexi Oral Liquid and drinking water respectively,once a day,for one year.The changes of general indexes and health evaluation indexes before and after intervention were observed.[Results]The average blood lead level of 320 lead-exposed workers reduced from 330.3 μg/L before intervention to 293.3 μg/L after intervention,while the average hemoglobin content increased from 124.5 g/L to 127.5 g/L,and the differences between before and after intervention were significant(P0.05).The symptoms in group A,group B and group C were improved at different levels as compared with group D,while the annual times of sick and total days of sick leave decreased,and the order of change degree from high to low was group C,group B and group A.[Conclusion]Lidexi Oral Liquid has the significant protective effect on lead-exposed workers.
