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。

A strain of breast tumor cell line ZHL2006 was established and biologically identified. The ZHL2006 cells grew fast in vitro and the population doubling time was 43.6h. Electronmicroscopical observation showed that there were microvilli on the surface of the cells, nucleus irregularity, karyoplasmic ratio increased, nucleolus distinctness, et al.. Chromosome number and structure were abnormal. Immunohistochemistry showed that PCK were expressed. The ZHL2006 cell line could form onto clone in soft agar and had oncogenicity in athymic mice.

ZHL2006细胞在体外生长迅速，群体倍增时间为43.6h；倒置相差显微镜及Giemsa染色镜下观察细胞为多边形及梭形；透射电镜观察可见细胞表面有微绒毛，核高度不规则，核浆比例增大，核仁明显等；染色体数目和结构异常；广谱细胞角蛋白染色阳性，说明其自上皮而非来自基质；同时ZHL2006细胞系在软琼脂中可形成克隆，具裸鼠致瘤性。

Objective: To establish a method of in vitro cultivation of epithelial cells of keratocystic odontogenic tumors.

目的：建立牙源性角化囊性瘤上皮细胞体外培养体系并进行初步鉴定。

观察9例甲状腺嗜酸细胞腺瘤，在光镜观察的基础上，用免疫组织化学方法检测细胞角蛋白、甲状腺球蛋白、神经元特异性烯醇化酶、波形蛋白和降钙素。

Results It was found that the most frequent sites of BCC were the nose and periocular area,the age of highest incidence of BCC was ranged from 40 to 49, and solid BCCs were most common compared with other types. 28.57% of the cases were misdiagnosed clinically as pigmented nevus, seborrheic keratosis, malignant melanoma, et al.

结果：BCC最好发的部位是鼻部和眼周，发病年龄高峰40～49岁，实体型BCC最常见，28.57%的病例临床上被误诊为色素痣、脂溢性角化、恶性黑素瘤等。

The intracellular expression of viral gene and phenotypical change of transformants were examined.

结果：分离获得了可长期体外培养的SV40转化细胞克隆，已传23代以上，体外存活超过250d；DNA印迹实验显示SV40大T基因已整合至细胞染色体内，间接免疫荧光检测示多数细胞胞核内有大T基因产物的表达；转化细胞对裸鼠无致瘤性，并可正常表达角蛋白。

To our knowledge, synovial chondromatosis of the knee joint in the posteromedial corner has not been reported in the literature.

据我们所知，在膝关节后内侧角的滑膜软骨瘤病在文献中还未见报道。

OBJECTIVE Cholesteatoma of the middle ear is an inflammatory disease characterized by the presence of hyperproliferative keratinizing squamous epithelium in the middle ear cavity and destruction of adjacent bone.

目的：中耳胆脂瘤是一种以鳞状角化上皮过度增殖和邻近骨质破坏为特征的炎性疾病。

Acoustic neuromas is the most tumors in CPA.MRI is the first choice for the tumors in CPA.

桥小脑角区肿瘤中以听神经瘤最多见，MR能对CPA区肿瘤作出较好的诊断。

The mata mata is quite visually distinctive: its head is triangular, large, and extremely flattened, with many tubercles and flaps of skin, most notably a 'horn' on the nose.

枫叶龟长得很有特色：它的头是三角形的、很大、很平，身体上有很多小瘤和凸起物，最有特色的就是鼻子上有个&角&。
