Distribution of Tumor Markers (PAP，PSA) and HNK-1)in Prostatic Cancer

Sixty-eight paraffin-embedded tissue sections were immunohistochemically stained by ABC method using anti-PAP,anti-PSA and anti-HNK-1 monoclonal anti- bodies .The ratio of positively stained cancer cells and the intensity of the immunos-aining were observed and their relationship with the histological differentiation of prostate cancer was revealed .The results showed that the positive rate of anti-PAP,and-PSA and anti-HNK immunohistochemical reaction was percent，respectively，with the total positive rate being percent.The anti-PAP immunohistochemical reaction was not related to the ifferentiation of the prostatecancer，while the anti-PSA and anti-HNK immunohistochemicasl reaction paral-leled to the tumorous differentiation.
