The 3rdpassage chondrocytes were divided into blank group, different concentration PAP groups,different concentration glucosaminsalfate groups and were sequently passaged to 4thgeneration. The 2nd passage chondrocytes was contrasted as young cells group. Thechondrocytes of different groups were detected with the methods of histochemistry forS-A-β-gal, and with alcian blue test for the content and constructure of GAG of ECM,immuocytochemistry for typeⅡcollagen and PCNA, MTT assay for proliferation, RT-PCRfor typeⅡcollagen and Aggrecan, flow cytometry for cell life cycle and proliferationindex,by which to observe PAP"s function regarding to the appearance and functional status inthe process of chondrocyte"s cataplasia and senescence.
