肌红蛋白(简称Mb)是在心肌与骨骼肌中合成的低分子量带氧链的蛋白质。当心肌或骨骼肌受损时,Mb大量释放入血液循环中使其在血清与尿的含量增高。因为Mb的含量低微,过去使用的化学测定法均不够敏感。自1975年以来建立Mb放射免疫测定法后使Mb的微量测定有了改观。我们在1982年～1984年6月对进行性肌营养不良症50例进行血清 Myoglobin (Mb for short) is a low molecular weight oxygenated protein synthesized in myocardium and skeletal muscle. When myocardium or skeletal muscle is damaged, Mb is released in a large amount into the blood circulation to increase the level of serum and urine. Due to the low content of Mb, the chemistries used in the past were not sensitive enough. The establishment of Mb radioimmunoassay since 1975 has led to a change in the microdialysis of Mb. We conducted sepsis in 50 patients with progressive muscular dystrophy from 1982 to 1984
