自我们采用日立835—50型高速自动氨基酸分析仪对60名正常人的氨基酸组成。与各型病毒性肝炎共计130例进行血清游离氨基酸检测。结果如下:正常人平均数值为163.97μmol/L,BCAA/AAA3.27±0.58;急性肝炎:血中谷、酪氨酸增高为21.83μmol/L,异亮和精氨酸降低为14.06μmol/LBCAA/AAA2.89±0.47;慢迁肝:血中五种氨基酸增高,有酪、谷、胱、赖及组氨酸平均增 Since we use Hitachi 835-50 high-speed automatic amino acid analyzer on the amino acid composition of 60 normal people. A total of 130 cases with various types of viral hepatitis serum free amino acid detection. The results were as follows: normal average 163.97μmol / L, BCAA / AAA3.27 ± 0.58; acute hepatitis: blood valley, tyrosine increased 21.83μmol / L, isoleucine and arginine decreased to 14.06μmol / LBCAA / AAA2.89 ± 0.47; slow moving liver: blood five amino acids increased, with cheese, cereal, bladder, Lai and histidine average increase
