Ceruloplasmin (CP) in peripheral leucocytes was determined by radioimmunoassay.It was observed that leucocytes of normal persons and leukemic patients contained CP. TheCP contents of polymorphonuclear cells (PMN) and blast cells of acute leukemia not in re-mission were both significantly higher than that of normal (P<0.05) and than that of acuteleukemia complete remission (P<0.05). 相似文献

近年来金属致癌问题的研究日益受到重视,在流行病学、动物实验及体外致突变试验等方面都取得一定进展,本文就有关问题作一文献综述。流行病学及动物实验砷近年研究证实铸铜工人因吸入三氧化砷矿尘,肺癌死亡率显著增高。肺癌发病率与大气中砷浓度有正相关关系。Higgins 等一组铸铜工人中吸入高浓度砷尘者,死于肺癌的观察值与期望值之比(0/E)为14.3,而吸入中等浓度与低浓度者分别为1.95与1.70,前者病死率显著增高(P<0.01)。有人认为, 相似文献
