我们用原子吸收光谱仪测定了40例45岁以上人的血清铬含量,40例中20例为已确诊的心肌梗塞住院患者,20例经体检无心血管疾病,半个月内未服用过药物。被检者于晨空腹静脉取血2ml,静置后离心,分离血清于试管中,封口置-20℃保存,半个月内测定。测定时用5‰Tritor X-100(A.R)和5‰HNO_3(G.R)稀释,混匀,用 SpectrAA-4 OP 原子吸收分光光度计、石墨炉原子吸收法测定铬
We measured the serum chromium levels in 40 patients over the age of 45 by atomic absorption spectroscopy. Twenty patients were diagnosed with myocardial infarction in 40 patients, 20 patients were free of cardiovascular disease by physical examination, and had not taken drugs within half a month. The subjects were seized in the morning fasting venous blood 2ml, centrifuged after standing, the sera were separated in the test tube, stored at -20 ℃ seal, measured within half a month. The assay was carried out by diluting with 5 ‰ Tritor X-100 (A.R.) and 5 ‰ HNO 3 (G.R.), mixing, and determining the concentration of chromium by SpectrAA-4 OP atomic absorption spectrophotometer and graphite furnace atomic absorption spectrometry
