Recent reports have shown that the inhibition of cholesteatoma epithelial cell apoptosis plays an important role in the formation and development of cholesteatoma.

最新研究表明胆脂瘤上皮细胞凋亡受到抑制在中耳胆脂瘤的发生和发展中起着重要作用。

Results MMP-2 positive cells are localized in peripheral columnar while no positive cells are seen in odontogenic karatocysts and dentigerous cysts.

结果 成釉细胞瘤中MMP-2阳性染色位于肿瘤外周柱状细胞的胞浆中，中心星网状细胞未见表达；角化囊肿和含牙囊肿的上皮细胞中均未见MMP-2的阳性表达。

Methods Epithelial cells and fibroblast from ameloblastoma, keratocyst, dentigerous cyst, radicular cyst and oral mucosa were cultured and observed by phase-contrast microscope.

原代体外培养成釉细胞瘤细胞、牙源性角化囊肿、根端囊肿及口腔粘膜的上皮细胞和成纤维细胞，倒置光相差显微镜观察。

Most patients' death arise from the metastatic spread of primary tumors There is an urgent need for the finding of novel anti-tumor and anti–metastatic drugs to improve the quality of life and survival rate of patents Justicia procumbens is an herb and used to reduce fever inflammation and canker in Taiwan We've detected that 0 3 μM JA could effectively inhibit the proliferation of oral cancer cells OC-2 and HSC3 but not normal oral keratinocytes in MTS assay JA-treated OC2 underwent apoptosis as suggested by increased sub-G1 DNA contents condensed nuclear morphologh and DNA fragmentiation The migration activity of OC-2 was also significantly reduced by treatment with low concentration of JA The expression of ?

大部分的口腔癌病患死於原位癌的转移和扩散，寻找有效抗癌和抗转移的药物疗法来增进病患的生活品质和存活率，对治疗口腔癌而言非常重要。爵床草是台湾民间常用草药，常被用来消炎止热和治疗口疮、乳瘤。我们利用MTS分析，发现处以0 3 μM的JA 48小时，即可有效抑制口腔癌细胞OC-2和HSC3的增生，但不影响正常口腔上皮细胞生长。OC-2经JA处理后，其sub-G1的DNA含量增加，并可观察到DNA固缩和梯度断裂的现象，说明JA可使OC-2走向细胞凋亡。除此之外，0 3 μM的JA亦可有效降低OC-2的迁移能力。

Cytology revealed 3-dimensional groups of ductal cells in a background of myoepithelial cells and stromal cells, consistent with a fibroadenoma.

对该肿块进行细针抽吸活检，细胞学显示以肌上皮细胞和基质细胞为背景的三维导管细胞结构，与纤维腺瘤结构一致。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

CDK4与P16在中耳胆脂瘤发生中是共同而非单独起作用的，从细胞周期的角度可反映胆脂瘤上皮细胞过度增殖的同时也增强负调控因子来抑制增殖，使凋亡同时加快而达到新的平衡。

KCOT epithelial cells could be serially cultured in vitro in K-SFM by techniques suggested in this study.

采用无血清的角化细胞培养基可在体外进行牙源性角化囊性瘤上皮细胞的连续培养。

To discuss the clinical significance of cervical fall off epithelia in STD clinic by TCT and vaginoscopy examination and sex behavior assessment in screen CIN.

目的 探讨在性病门诊通过宫颈脱落上皮细胞应用液基薄片细胞学检查和阴道镜检查及性行为因素在筛查妇女宫颈上皮瘤样病变中的临床意义。

Objective: To investigate amplification of the human telomerase RNA component gene in the cervical exfoliated cells and to explore its value in diagnosis and treatment of cervical intraepithelial neoplasia and malignancy.

目的：研究宫颈脱落细胞中人端粒酶RNA组分基因的表达，探讨其在宫颈上皮内瘤变及鳞状上皮细胞癌诊断中的价值。

I didn't watch TV last night, because it .
