本文报告64例正常人和178例各种肝胆疾病患者的血清ADA活力测定结果,并与同时测定的GPT和γGTP活力作了比较。发现在急性肝炎恢复期ADA活力较GPT恢复正常为迟,有助于反映残存的肝病变;慢性活动性肝炎、肝硬化等慢性肝病时ADA阳性率高于其他酶,但慢性迁延性肝炎时多正常;胆道疾病时ADA在大部分病例正常,故测定血清ADA有助于鉴别肝细胞性和阻塞性黄疸。 This article reports the results of serum ADA activity measurements in 64 normal subjects and 178 patients with hepatobiliary disease and compares them with the measured GPT and γGTP activities. Found that ADA activity in recovery of acute hepatitis than GPT return to normal later, help to reflect the residual liver disease; chronic active hepatitis, cirrhosis and other chronic liver disease ADA-positive rate higher than other enzymes, but when chronic persistent hepatitis Normal; ADA in biliary disease is normal in most cases, so the determination of serum ADA helps identify hepatocellular and obstructive jaundice.
