Involvement of COX-2 and free radical-related enzymes in the malignant transformation of ovarian endometrial cyst

超氧化物歧化酶（SOD）在子宫内膜腺癌中的表达本研究探讨了Cu/Zn-SOD在子宫内膜腺癌中的表达及其在不同组织学类型中的表达差异，并对Cu/Zn-SOD在子宫内膜腺癌中的表达进行了研究。（3）Cu/Zn-SOD在子宫内膜癌中表达较强，尤其在透明细胞腺癌中，与正常子宫内膜相比。提示Cu/Zn-SOD的表达可能与子宫内膜腺癌的初始致癌因素有关。①环氧合酶-2在卵巢巧克力囊肿和卵巢癌中的表达卵巢巧克力囊肿中的表达明显高于对照组。在卵巢癌的各组中，类卵巢癌的染色最高，其次是透明细胞型和浆液性。在大多数卵巢巧克力囊肿和卵巢癌中，考克斯-2呈弥漫性颗粒状染色于胞浆中。考克斯-2染色在基底膜和腺腔的定位无差异。总之，考克斯-2的过度表达可能与卵巢巧克力囊肿的恶性转化密切相关。

◇Immunohistochemical expression of superoxide dismutase in endometrial adenocarcinomaThis study examined : (1)the distribution of Cu/Zn-SOD expression in endometrial adenocarcinomas ; (2)differences in this expression based on histological type ; and (3)variations in patient survival rate with intensity of expression.Stronger expression of Cu/Zn-SOD was observed in endometrial carcinomas, particularly in clear cell adenocarcinoma, when compared to normal endometrium. This suggests that Cu/Zn-SOD expression might be correlated with initial carcinogenetic factor of the endometrial adenocarcinoma.◇Involvement of Cyclooxygenase-2 in Ovarian Chocolate Cyst and Ovarian Cancerthe expression in ovarian chocolate cyst revealed significantly higher than that of the control. Among the groups of ovarian carcinoma, the highest staining was found in endometrioid type, followed by clear cell type and serous type. In the majority of ovarian chocolate cyst and ovarian cancer cases, COX-2 was diffusely and granularly stained in cytoplasm. No difference in the localization of COX-2 staining was seen between the basement membrane and the lumen of glands. In conclusion, overexpression of COX-2 may be intricately involved in malignant transformation of ovarian chocolate cysts.
