ABSTRACT
Objective To study the expressions of TGF-?1 and p21WAF1 in middle ear cholesteatoma and discuses their effects on cholesteatoma.Methods The expressions of TGF-?1 and p21WAF1 were determined by immunohistochemical S-P technology and computer image analysis in 20 specimens of cholesteatoma epithelium and 10 specimens of normal external canal skin.Results ① p21WAF1 and TGF-?1 could be detected in middle ear cholesteatoma and in normal ear canal skin.p21WAF1 was located at karyon,taking on yellow-brown pellet;TGF-?1 was located at cytoplasmic,taking on yellow-brown pellet.②The p21WAF1 positive rate in middle ear cholesteatoma was 65%;and there were almost no positive cells in normal external ear canal skin.p21WAF1 positive cells were detected in each layers,its LI was 28.9%?6.7%.Compared with normal ear canal skin,the expression level of p21WAF1 in middle ear cholesteatoma epithelium was higher than that in normal ear canal skin(P
