摘要(Abstract):
采用免疫组化方法,观察bcl-2(Bcellymphoma-2)基因产物在多形性腺瘤及其恶变组织中的表达与分布,以图像分析仪进行计数分析。结果显示肿瘤组织中以导管样上皮细胞、粘液样细胞以及软骨样细胞的阳性表达较高,而鳞状上皮团块中,bcl-2表达极低。各组阳性病例比例:对照组5例慢性诞腺炎为80%(4/5),15例多形性腺瘤为80%(13/15),7例多形性腺瘤恶性病变为86%(6/7)。图像分析仪计数阳性细胞显示慢性诞腺炎为5%,多形性腺瘤为42%,而恶性病变为57%,统计与分析表明良性及恶性多形性腺瘤与对照组比较,差异有显著性(P<0.05),而良性和恶性组间,差异无显著性(P>0.05)。
bcl2 is a apoptosissuppressing oncogene,and plays an important role in oncogenesis.bcl2 protein was detected by immunohistochemistry in 5 cases with chronic sialadenitis,15 cases (benign) and 7 cases (malignant) of pleomorphic adenoma of salivary glands.The results showed that bel2 expression in 4/5 cases with chronic sialadenitis,13/15 cases with benign and 6/7 cases with malignant pleomorphic adenoma were observed,respectively.Image analysis indicated 5%,42%,and 57% of total cells were positive for bcl2 in three groups,respectively.These findings suggest bcl2 gene may play an important role in developmen of pleomorphic adenomas.
