尿中δ-氨基乙酰丙酸(δ-ALA、筒称ALA)测定,近年来国内外已有不少文献报导,多数认为可作为铅中毒早期诊断的一项重要参考指标,而且测定比较灵敏,现已正式列入国家诊断标准。国内对尿中ALA含量正常值上限已有不少报导,但限于各地自然条件、生活习惯以及对象选择、测定、统计等方法有所不同,其结果各有差异。为了探讨和确立我地区正常人尿中ALA正常值,为今后铅中毒的防治提供客观依据,我们于七八年五月也对吉林地区铁路系统102例正常人做了调查,现将结果报告如下: 测定对象及方法选择居住吉林市一年以上,年龄22-56岁,无铅作业史,近期未服任何药物,身体健康的列车段、车辆段、配件厂等单位工人共102例作为测定对象,其中男性58例,女性44例。随机采取一次晨尿,进行尿中ALA测定。
Urinary δ-aminolevulinic acid (δ-ALA, tube ALA) determination, in recent years, many domestic and foreign literature has been reported, most think it can be used as an early lead poisoning diagnosis of an important reference index, and the determination of more sensitive, Is now officially included in the national diagnostic criteria. There are a lot of reports on the upper limit of ALA in urine in China, but the results are different due to different natural conditions, living habits, object selection, measurement and statistics. In order to explore and establish normal urinary ALA in our area, provide an objective basis for future prevention and control of lead poisoning. We conducted a survey on 102 normal people in Jilin railway system in May 1988. The results are reported as follows : Determination of objects and methods Selected living in Jilin City for more than one year, aged 22-56 years old, lead-free homework history, the recent did not take any drugs, good health train sections, depots, parts factories and other units a total of 102 workers as the measurement object , Including 58 males and 44 females. Morning urine taken at a random, for urinary ALA determination.
