Activity of beta-glucuronidase (GL), placentar izoenzyme of alkaline phosphatase (PLAP), cathepsin B (CB) and concentrations of carcinoembryonic antigen (CEA) were determined in serums and bile of pigs with experimental cholangiocarcinoma and in control animals. No differences in serum GL, PLAP, CB activities or CEA were observed. The same was found in bile for GL, PLAP and CEA. However, in bile the situation was different for CB. In all the tumour bearing animals we were able to demonstrate in the course of tumour development a stricking progression in CB activity. Very impressive was namely an elevation of CB alkaline-stable form, generated (according also to the chromatographic studies of the bile) from primary cholangiocarcinoma tissue.
