铅对机体的损害是多方面的,现在常用的一些指标均不能反映铅对内脏器官的影响,测定精氨酸酶和激肽释放酶的活性,可分别反映铅对肝、肾的早期损伤。 作者对60名铅作业工人进行了研究,除测定精氨酸酶与激肽释放酶活性外,同时测定了一些常用指标。例如:血铅(pb-B)、尿铅(pb-U)、δ-氨基-γ-酮戊酸脱水酶(δ-ALA-D)、尿δ-氨基-γ-酮戊酸(δ- Lead damage to the body is multifaceted, and some of the commonly used indicators can not reflect the impact of lead on visceral organs, determination of arginase and kallikrein activity, respectively, can reflect the early liver lead and kidney damage. The authors conducted a study of 60 lead workers, in addition to determination of arginase and kallikrein activity, while the determination of some common indicators. For example, the blood levels of pb-B, pb-U, δ-ALA-D and urinary δ-amino-
