摘　　要：目的　观察PTK抑制剂Genistein对人卵巢癌裸鼠皮下移植瘤生长的影响。方法　对 3 0例裸鼠建立人卵巢癌皮下移植瘤模型 ,共分为 5组 :对照组 (含 0 0 4%DMSO的生理盐水 ) 0 2mg kg ,Genistein治疗组 0 4mg kgGenistein治疗组 (皮下注射 ) ,Cisplatin( 4mg kg ,静脉推注 )治疗组 ,Genistein与Cisplatin联合治疗组。观察不同药物治疗后第 7、14、2 1、2 8d各组裸鼠皮下移植瘤生长情况及裸鼠体重的变化 ,并进行病理组织学检查。结果　 0 .4mg kgGenistein皮下注射 ,对SKOV3裸鼠移植瘤的生长有明显抑制作用 ,与对照组相比 ,瘤体重量降低 ,肿瘤体积减小 ,坏死面积显著增加 ,但对裸鼠体重无明显影响。应用 0 4mg kgGenistein与 4mg kgCisplatin(静脉推注 )联合处理SKOV3裸鼠移植瘤有增强抑制作用。结论　Genistein具有抑制人卵巢癌裸鼠皮下移植瘤生长的作用 ;Objective To investigate the effects of genistein used alone and in combination with cisplatin on the treatment of human ovarian carcinoma transplanted subcutaneously in nude mice. Methods Nude mouse model of human ovarian carcinoma transplanted subcutaneously was established. A total of 30 mice were divided into 5 groups: control group (0 04% saline), genistein group (subcutaneous injection of genistein at 0 2 mg/kg and 0 4 mg/kg), cisplatin group (intravenous injection of cisplatin at 4 mg/kg), and genistein plus cisplatin group. The growth of the subcutaneously transplanted tumor and changes of mouse body weight in each group after treatment using different medication regimens were observed at 7, 14, 21, and 28 d. Histopathological examination was also conducted. Results Genistein (0 4 mg/kg) had significantly inhibitory effect on the transplanted xenograft growth in vivo . Tumor volume, tumor weight, and T/C ratio (mean volume of treated group/mean volume of control group) decreased. Significantly enlarged necrotic areas were found in genistein treated group. The weight loss of nude mice after treatment with genistein was not significantly different from in the control group. Conclusion Genistein has the inhibitory effect on the growth of human ovarian carcinoma transplanted subcutaneously in nude mice. Genistein (0 4 mg/kg) in combination with cisplatin (4 mg/kg) has a synergistic effect on xenograft of human ovarian cancer cell line SKOV 3 in nude mice. The results provide the evidence for the potential usefulness of genistein for the prevention and treatment of human ovarian carcinoma.
