胰管系统由闰管、小叶内导管、小叶间导管和主胰管组成。很多形态学研究是用微量注射或三维结构重建技术进行的,然而这些技术仍然不能使我们知道导管系统整个行程的细节。另一方面,酶组织化学方法证明了胰管中存在有碱性磷酸酶、ATP酶、碳酸酐酶和γ-谷氨酰转肽酶(γ-GT)。但这些研究中没有一个能全面地显示导管系统的行程。再则,采用γ-GT酰组织化学方法所得结果差异很大,这可能由于最后一步偶氮染料染色法的反应产物很
Pancreatic duct system by the intercalary tube, lobular catheter, interlobular duct and the main pancreatic duct. Many morphological studies are performed using microinjection or 3D reconstruction techniques, yet these techniques still do not allow us to know the details of the entire travel of the catheter system. On the other hand, enzymatic histochemistry demonstrated the presence of alkaline phosphatase, ATPase, carbonic anhydrase and gamma-glutamyl transpeptidase (γ-GT) in the pancreatic duct. However, none of these studies provide a complete picture of the catheter system. Furthermore, the results obtained using gamma-GT acyclic chemistry vary widely, possibly due to the fact that the reaction product of the last azo dye staining is very
