urinary amylase

Phloroglucinol method used to measure D-xylose urinary excretion rate; use of iodine content of Determination of urinary amylase; rats were sacrificed after the application of physical methods, calculated to promote the spleen index and rate of rat small intestine.

利用间苯三酚法，测定尿D-木糖排泄率；利用碘比色法测定尿淀粉酶含量；处死大鼠后，应用物理方法，公式计算脾脏指数及大鼠小肠推进率。

11 patients were treated with comprehensive therapy and early nose/ jejunum nutrition, and we detected their abdominal pain, serum and urinary amylase to judge the clinical effectiveness.

11例ASP患者经综合治疗，早期经鼻&空肠营养，监测其腹痛，淀粉酶变化，判断临床效果。

the sensitivity and specificity of serum amylase test were 86.2% and 84.9% respectively, and of urinary amylase test were 82.8% and 82.1% respectively.

而血淀粉酶敏感性为86.2%，特异性84.9%；尿淀粉酶敏感性82.8%，特异性82.1%。

results the lc was performed 20~ 40 days after the onset of pancreatitis and 15 days after the recovery of serum and urinary amylase levels. an abdominal drainage tube was placed in 9 patients.

结果21例均在急性胰腺炎发作后20~40d，血、尿淀粉酶正常15d后，成功实施LC，9例放置腹腔引流管。

results: the sensitivity and specificity of the ratio of urinary amylase to urinary creatinine assay were 92.31% and 92.00% ( cut off value: 75%), which were also higher than those of the two traditional assays for the diagnosis of acute pancreatitis.

结果：急性胰腺炎尿液Uamy/Ucr敏感性为92.31%，特异性为92.00%，均高于临床常用的诊断指标Samy和Uamy。
