The enzymic activity of lipase, lysosomal markers (beta-glucuronidase and acid phosphatase) and cathepsin was checked in the pancreatic subcellular fraction of control and whole-body X-irradiated rats. Incubation of granules (zymogen and mitochondrial fraction) under hypoosmotic conditions resulted in greater activity of lipase and cathepsin in the irradiated than in the control group. However, formation of different pattern of enzymatic activity was found (both in the sediments and in the supernatant) in single and fractionated irradiated pancreas.
在对照大鼠和全身X射线照射大鼠的胰腺亚细胞组分中检测了脂肪酶、溶酶体标志物（β-葡萄糖醛酸酶和酸性磷酸酶）和组织蛋白酶的酶活性。在低渗条件下孵育颗粒（酶原和线粒体组分），结果发现照射组的脂肪酶和组织蛋白酶活性高于对照组。然而，在单次照射和分次照射的胰腺中（沉积物和上清液中）均发现了不同的酶活性模式。
