serum total bilirubin, alanine aminotransferase, aspartate aminotransferase significantly decreased(p0.05) within one month after ptbd.

引流术后血清总胆红素、谷丙转氨酶、谷草转氨酶均较术前显着降低（p0.05）。

objective: to study the effects of smoking or diabetes on the level of aspartate aminotransferase in gingival cervical fluid (gcf-ast).

目的：研究吸烟、糖尿病对牙周龈沟液中天冬氨酸转氨酶（gcfast）水平的影响。

the levels of alanine aminotransferase (alt) and aspartate aminotransferase (ast) in the serum samples were measured by using autobiochemistry analyzer.

并且采用全自动生化分析仪检测丙氨酸氨基转移酶（alt）和天冬氨酸氨基转移酶（ast）。

objectiveto assess the clinical significance of detection of serum creatine kinase (ck), creatine kinase (ck-mb), lactate dehydrogenase (ld), and aspartate aminotransferase (ast) in psychotics.

目的探讨精神病病人血清中肌酸激酶（ck）、肌酸激酶同工酶（ck-mb）、乳酸脱氢酶（ld）和天门冬氨酸氨基转移酶（ast）检测的临床意义。

objective to observe the activity changes of serum aspartate aminotransferase (ast), creatine kinase (ck) and lactate dehydrogenase (ldh) of the patients with acute organic phosphorus intoxication.

目的观察急性有机磷农药中毒患者血清中天氡氨酸转氨酶（ast）、肌酸激酶（ck）和乳酸脱氢酶（ldh）的活性变化。

serum alkaline phosphatase and aspartate aminotransferase were increased in 15 and 18 cases respectively.

血清堿性磷酸酶升高者为15例，天冬氨酸转氨酶升高者为8例。

in this study, three strains overexpressing transaminase were constructed by gene engineering, and the expression of the aspartate aminotransferase (encoding by aspc gene) in e.
