Abstract

We have measured serum nickel concentrations using flameless atomic absorption spectrophotometry. In 71 normals the median concentration was 1.0 micrograms/L, range less than 0.6-3.0 micrograms/L. Increased concentrations (p less than 0.05) were found in patients with chronic renal failure (CRF) treated conservatively (median 1.6 micrograms/L, range less than 0.6-3.6 micrograms/L). Significantly increased concentrations (p less than 0.001) were found in patients treated by continuous ambulatory peritoneal dialysis (CAPD) (median 8.6 micrograms/L, range 5.4-11.4 micrograms/L) and haemodialysis. In patients on haemodialysis, post-dialysis concentrations (median 8.8 micrograms/L, range 3.0-21.4 micrograms/L) were significantly higher (p less than 0.001) than pre-dialysis values (median 8.6 micrograms/L, range 0.6-16.6 micrograms/L).

慢性肾衰竭患者血清镍浓度升高。
我们用无焰原子吸收分光光度法测定了血清镍浓度。71例正常人中位浓度为1.0微克/升,范围小于0.6 ~ 3.0微克/升。慢性肾衰竭(CRF)患者保守治疗时,浓度升高(p < 0.05)(中位数1.6微克/升,范围小于0.6-3.6微克/升)。在连续动态腹膜透析(CAPD)和血液透析治疗的患者中(中位数8.6微克/升,范围5.4-11.4微克/升)发现浓度显著升高(p < 0.001)。在血液透析患者中,透析后浓度(中位数8.8微克/升,范围3.0-21.4微克/升)显著高于透析前值(中位数8.6微克/升,范围0.6-16.6微克/升)(p < 0.001)。
