| 摘 要： | 目的研究口腔上皮组织癌和癌前病变的细胞动力学变化特征。方法采用Ｓａｌｅｙ的ＤＭＢＡ涂布诱导法，建立金地鼠颊囊癌前病变模型，并用溴脱氧尿苷流式细胞动力学检测方法，对３０只叙利亚种金地鼠进行分组对照研究。结果涂药组光镜下的细胞病变程度随涂药时间延长而逐渐加重，而空白对照组无变化；ＦＣＭ检测显示涂药组与对照组在Ｓ期阳性细胞检出率存在显著差异。即使在光镜下表现为轻度不典型增生时，ＦＣＭ检测结果也有显著差别。结论金地鼠颊囊癌前病变具有细胞异常增殖的细胞动力学特征

| Abstract: | Objective In order to study cellular dynamicfeatures in carcinoma and premalignancy originated inepithelial tissue.Methods The golden hamster pouch premalignant model with dimethylbenzanthracence (DMBA) smeared was established by Salley and detected with flow cytometry (FCM) binding to bromodeoxyuridine (BRDU), 30 Syrian golden hamsters were grouped and done contrast study.Results The cellular lesions were aggravated gradually along with extention of smeared DMBA microstopically.FCM detective results demonstrated that the detective rate of Sporiod cell between contrast and smeared group had significant difference.Even though mild dysplsia presented microscopically FCM detective result and significant difference.Conclusion The study suggests that golden hamster cheek pouch premalignancy has cellular dynamicfeatures of dysplasia. |
