ABSTRACT
Objective To study the changes of AKP activity and its cytochemistry position during liver regeneration following partial hepatectomy. Methods Using colorimetry to analyze AKP activity; using non-denatured electrophoresis technique to analyze the kinds and activity of AKP; using electron microscope cytochemistry to analyze its position. Results During liver regeneration, AKP activity had two peaks at 16*!h and 19*!h and followed by decline dramatically; Three hepatic-derived AKP isoenzymes were detected, and 180*!kD AKP appeared only in liver regeneration; AKP appeared in different part with the process of liver regeneraion.Conclusion AKP plays an important role in liver regeneration and it may involve in cell metabolism, material transportation, DNA synthesis and cell differentation.
