本文通过对 6 9例健康人体检和 132例各类消化道肿瘤患者的甘氨酰脯氨酸二肽氨基肽酶 (GPDA)的测定 ,发现 6 9例健康人的GPDA为 6 6 7± 2 0 3u/L(X±S) ,35例肝癌组为 196 6± 132 1u/L (X±S)、 12例肝硬化组为 15 5 8± 6 2 9u/L (X±S) ,明显高于健康人组 (P <0 0 1)。 31例胃癌和 2 8例肠癌、 2 6例食道癌分别为 30 9± 13 4u/L、 40 3± 2 2 6u/L、 41 2± 2 5 9u/L ,明显低于健康人组 (P <0 0 1)。
In this paper, the determination of glycyl-proline dipeptidyl aminopeptidase (GPDA) in 69 healthy human subjects and 132 patients with various types of digestive tract tumors found that 6 of 9 healthy individuals had 6 6 7 2 GPDA. 0 3u/L(X±S), 35 cases of liver cancer were 196 6± 132 1u/L (X±S), and 12 cases of liver cirrhosis were 15 58±6 2 9u/L (X±S). Higher than healthy group (P <0 01). 31 cases of gastric cancer, 28 cases of colorectal cancer, and 26 cases of esophageal cancer were 30 9± 13 4u/L, 40 3± 2 2 6u/L, and 41 2±2 5 9u/L, respectively, which were significantly lower than those in the healthy group ( P < 0 0 1).
