In ACC, NGF,TrkA and p75 mainly existed in cells of duct-like, cribriform and mass-like structures.According to the optical density scanning of immunohistochemistric stain of NGF and TrkA in salivary gland and tumor tissues and quantification analysis, it was shown that the average optical density of NGF and TrkA increased in order of salivary gland tissues around neoplasm, mucoepidermiod carcinoma, and adenoid cystic carcinoma.

2叫 吉林大学硕士学位论文通过对NGF和TrkA在涎腺组织和涎腺肿瘤中的免疫组织化学染色结果进行光密度扫描，对所测平均光密度定量分析，结果显示：NGF和TrkA平均光密度值按照肿瘤周围涎腺组织、豁液表皮样癌和腺样囊性癌依次升高，统计学分析在各组间均有极显著差异(P.01)，表明NGF和TrkA通过自分泌机制调控涎腺腺样囊性癌和豁液表皮样癌的生长与增殖，通过旁分泌机制参与涎腺腺样囊性癌向神经周围的浸润。

Results Of the 52 specimens, 38 were located in the ciliary body (73.1%), and 14 lesions involved the iris (26.9%). According to the results of histogenetic classification, the tumors of ciliary sensory epithelium were ranked the first place (20 cases, 38.5%) while malignant melanoma, the second one (14 cases, 26.9%) followed by melanocytoma (9 cases, 17.3%) and granulomatous lesions (5 cases, 9.6%).

结果 52例组织标本按解剖部位分类：位于睫状体病变38例（73.1%），原发于睫状体累及虹膜组织14例（26.9%）；按组织来源分类：占第1位者为睫状体神经上皮来源的肿瘤20例（38.5%），第2位者为恶性黑色素瘤14例（26.9%），第3和第4位者分别为黑色素细胞瘤9例（17.3%）和肉芽肿性炎性病变5例（9.6%）。

We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。

Neurothekeoma and plexiform fibrohistiocytic tumor are dermal neoplasms that share many clinical and histologic features and whose histogenesis is equally disputed.

神经鞘黏液瘤和丛状纤维组织细胞性肿瘤好发于皮肤，两者的临床特点和组织学特征有许多相同之处，但两者的组织发生仍具争议。

There were all kinds of tissue cells in the teratomas acquired from in-vitro differentiation, such as, neuro epithelium, skeletal muscle, respiratory epithelium. This further proved the isolated mouse ES cells could differentiate into three germ layers of tissue types.

体内分化实验所获得的畸胎瘤中存在各种组织细胞，如一些神经上皮样组织；横纹肌；呼吸上皮样组织等，这进一步证明所分离获得的小鼠ES细胞具有三个胚层的分化能力。

Using immuno-histochemical, tissue cultural and immuno-electron microscopic methods, based on nerve-endocrine-immune net, the dynamic changes of 4 brain-gut peptides and 6 inflammation factors of excised saccalus rotunds of rabbit stimulated by germs, LPS, exotoxin were observed.

MAIN OUTCOME MEASURES: Morphology change of spinal cord was detected by light microscope and electronmicroscope, secreted brain-derived neurotrophic factor was measured by immunohistochemistry and PT-PCR, and the combine behavioral score was used to assess the functional recovery of spinal cord.
