本文分析放射性免疫测定13例正常人和68例因胸痛而入冠心病监护室患者的血清肌红蛋白(Mb)水平。结果表明,正常人血清Mb为3～75 ng/ml,平均25±23 ng/ml。与其它作者所报告相同。在不典型胸痛患者(经观察无心肌损伤证据),其血清Mb值与正常组相同。32例急性心肌梗死病人,胸痛出现后12小时内血清Mb峰值均升高达200～5,500ng/ml,12～48小时达到高峰。每例心肌梗死患者以琼脂电泳法测定,证实血中均有MB-CPK(肌酸磷酸激酶同功酶)存在。其中8例入院时Mb水平已明显升高,而CPK总量仍在正常范围内。有23例
This article analyzes the radioimmunoassay of 13 normal individuals and 68 patients with chest pain due to coronary heart disease in patients with serum myoglobin (Mb) levels. The results showed that normal human serum Mb was 3 ~ 75 ng / ml, with an average of 25 ± 23 ng / ml. Same as what other authors have reported. In patients with atypical chest pain (no evidence of myocardial damage observed), the serum Mb values were the same as in the normal group. In 32 patients with acute myocardial infarction, the peak value of serum Mb increased to 200-5,500ng / ml within 12 hours after the onset of chest pain and peaked at 12-48 hours. Each patient with myocardial infarction measured by agar electrophoresis, confirmed that MB-CPK (creatine kinase kinase isoenzyme) exist in the blood. Eight of these patients had significantly increased levels of Mb on admission, while the total CPK was still within the normal range. There are 23 cases
