摘　　要：目的探讨牙源性角化囊性瘤(KCOT)开窗减压术前后Bcl-2、Ki-67的表达及开窗术治疗KCOT的可能机制。方法收集经病理证实的7例KCOT患者,分别于手术时及术后3个月、9个月切取病理标本,行Bcl-2及Ki-67免疫组化染色。资料进行统计学处理。结果 KCOT开窗术后Ki-67阳性表达细胞减少,增殖指数降低(P<0.05);Bcl-2阳性细胞较术前减少(P<0.05),术后9个月7例患者均呈阴性表达。结论开窗减压术后KCOT上皮增殖能力下降,可能是其治疗KCOT的部分机制。Objective To investigate the expression of Ki-67 and Bcl-2 protein in epithelium of keratocystic odontogenic tumor （KCOT） before and after decompression. Methods The paraflqn-embeded tissue sections of KCOT befor and after decompression were used for immunohistochemical detection of Ki-67 and Bcl-2, and the results were statistically analyzed. Results Ki-67 expression in KCOT was down-regulated after decompression（ P 〈 0. 05 ）. The Bcl-2 expression in postoperative KCOT epithelium was significantly less than ,in preoperative KCOT epithelium （ P 〈 0. 05 ）. Conclusion The proliferation of KCOT epithelium after decompression decreased, which may be part of the mechanism of decompression therapy.
