在许多病人中胰腺疾病的诊断是困难的。虽然α-淀粉酶和脂肪酶循环浓度增加已用来诊断急性和复发性胰腺炎。但这两种酶不仅仅只来自胰腺,所以血液浓度的升高必然不能和胰腺的异常相符合。胰蛋白酶只反映胰腺的生成情况,因血液中有该酶的抑制剂存在,所以其酶活性不易测定。作者用特异的、敏感的放射免疫试验测定了胰腺各种疾病时胰蛋白酶循环浓度的变化。结果表明:76例正常人血清胰蛋白酶平均值(±SD)是273±67微克/升,而20例非胰腺疾患的住院病人是266±66微克/升。因为两组之间的差别
In many patients the diagnosis of pancreatic disease is difficult. Although increased alpha-amylase and lipase circulating concentrations have been used to diagnose acute and recurrent pancreatitis. However, these two enzymes are not only from the pancreas, so the increase in blood concentration must not coincide with the anomalies of the pancreas. Trypsin only reflects the formation of the pancreas, due to the presence of inhibitors of the enzyme in the blood, so its enzyme activity is not easy to measure. The authors used a specific, sensitive radioimmunoassay to measure changes in trypsin cycle concentration for various pancreatic diseases. The results showed that the mean serum trypsin (± SD) in 76 normal subjects was 273 ± 67 μg / L, compared with 266 ± 66 μg / L in 20 non-pancreatic conditions. Because of the difference between the two groups
