近年来,在探索化学物质对肾脏的损害指标中,尿酶测定日益受到重视,而且普遍认为尿酶比其它肾功能指标更敏感。尤其是碱性磷酸酶(alkaline phosphatase,ALP)被认为是反映早期肾损伤很有前途的敏感指标。国内有人通过动物实验发现长期接触丙烯腈(acrylonitrile,AN)没有引起肾脏损害, In recent years, in exploring the indicators of chemical damage to the kidneys, urease assay is increasingly valued, and it is generally believed that urease is more sensitive than other indicators of renal function. In particular, alkaline phosphatase (ALP) is considered to be a very sensitive indicator of early renal injury. Some domestic animal experiments found that long-term exposure to acrylonitrile (acrylonitrile, AN) did not cause kidney damage,
