作者观察了试管内铅与镉对人体多形核白细胞(PMNL)活性及吞噬能力的影响。用台盼兰试验及乳酸脱氢酶(LDH)的释放来评价其活性,确定每100个多形核白细胞中的食用酵母菌数以评价其吞噬能力。结果表明用铅、镉金属离子与多形核白细胞温育20小时以后,未发现对其活性有明显的影响。这与用啮齿动物巨噬细胞的试验结果相反,后 The authors examined the effects of lead and cadmium in vitro on the activity and phagocytosis of human polymorphonuclear leukocytes (PMNL). Trypan blue test and the release of lactate dehydrogenase (LDH) to evaluate its activity, determine the number of edible yeasts per 100 polymorphonuclear leukocytes to assess its phagocytic capacity. The results show that lead, cadmium metal ions and polymorphonuclear leukocytes incubated for 20 hours after the activity was not found to have a significant impact. This contrasts with the experimental results of using rodent macrophages
