本文试图了解急性心肌梗塞患者血浆中21种游离氨基酸浓度的变化以探讨其临床意义。分别于入院确诊后21小时内(发作期)及30天后(稳定期)取清晨空腹时静脉血,用LKB-440型氨基酸自动分析仪,5梯度锂缓冲系统,分析血浆中21种游离氨基酸含量。结果9种氨基酸的血浆水平有显著差异。其发作期和稳定期的含
This article attempts to understand the changes of plasma concentrations of 21 free amino acids in patients with acute myocardial infarction to explore its clinical significance. Venous blood samples were collected in the early morning of fasting within 21 hours (onset) and 30 days (stable phase) respectively after admission, and 21 kinds of free amino acids in plasma were analyzed by LKB-440 automatic amino acid analyzer and 5-gradient lithium buffer system . Results The plasma levels of nine amino acids were significantly different. The onset and stability of the containing
