粪卟啉是血红蛋白形成过程中的重要中间产物——粪卟啉原的衍生物。近年来它的排泄量被采用为接触某些生产性毒物的非特异性指标,但国内迄今尚未见有关尿内粪卟啉正常值的报告。在尿样品的收集和计算方面,过去多数是收集24小时全尿,以24小时尿内含有量表示之。少数以微克/升表示。考虑到在实际工作中,要收集24小时全尿比较困难,故此次观察收集4小时尿液测定粪卟啉含量具有一定实用意义。 The coproporphyrin is an important intermediate in hemoglobin formation - a derivative of coproporphyrinogen. In recent years, its excretion has been used as a nonspecific index for exposure to some productive poisons. However, no report on the normal urinary excretion of porphyrin has been reported so far in China. In the collection and calculation of urine samples, most of the past collection of 24 hours of total urine, with a 24-hour urinary content expressed. A few in micrograms / liter said. Taking into account the actual work, to collect 24 hours of urine more difficult, so the observation of urine collected 4 hours to determine the content of coproporphyrin has some practical significance.
