目的：探讨碱性成纤维细胞生长因子对基质金属蛋白酶表达的影响及其在球囊术后再狭窄中的作用。

To explore the culture method of rat dental follicle cells in vitro.

探讨大鼠牙囊细胞体外培养的方法。

Benign cystic teratomas are well-differentiated tumors composed of a variety of parenchymal cell types representative of more than one germ layer, usually all three. The most common locations are the gonads and sacrococcygeus.

成熟囊状畸胎瘤是一种良性且分化良好的肿瘤，由胚胎原始细胞分化而成，由多於一层胚层之组织而成；好发位置为性腺体、骶骨与尾骨部或纵隔腔，十分罕见於头颈部。

Objective To observe the effects of microencapsulated rabbit sciatic nerve tissue transplantation on substance P expression in dorsal root ganglia after spinal cord hemisection injury.

目的 观察微囊化兔坐骨神经组织细胞移植对脊髓半横断后脊神经节P物质表达的变化。

Methods:33 cases were classified asⅠ,Ⅱ,Ⅲ according to heteromorphic degree of interstitial cells,nuclear fission and special interstitial ingredient.

对 33 例经病理证实的乳腺叶状囊肉瘤，根据间质细胞异形程度和核分裂数、是否浸润、是否含有特殊间质成分进行分级。

These cysts are lined by epithelium with eosinophilic cytoplasm and a hobnail morphology, and there is often ovarian-like stroma.

囊壁由含有嗜酸性胞浆的上皮围成，上皮细胞呈鞋钉状，常常有卵巢样间质。

Grossly, the tumors ranged from 0.7 to 17 cm, and exhibited a spongy or bubble wrap appearance reflecting the microscopic presence of variably sized cystically dilated tubules lined by a single layer of epithelium. The lining varied with a cuboidal, flat, and hobnail cell appearance, and the neoplastic cells had abundant eosinophilic cytoplasm and enlarged nuclei with prominent nucleoli.

大体上，肿瘤大小为0.7至17cm，海绵样或泡沫样外观，镜下观是大小不等的扩张成囊的管子，这些管子被覆单层上皮，上皮形态立方状、扁平状和鞋钉样，肿瘤细胞胞浆丰富、嗜酸，细胞核大，核仁明显。

Objective To examine whether hypersecretion of ovarian androgen in polycystic ovary syndrome results from abnormal androgen biosynthesis by theca interna cells.

目的 检验多囊卵巢综合征患者卵巢卵泡内膜细胞雄激素合成是否异常。

The results indicate that the larger the concentration of chitosan in the capsules is the slower the release rate of capsule. The biocompatibility tests of the three heparin microcapcules/PLA composite materials show that all materials are negative and have no obvious toxicity. There is no potential hypersusceptibility substance in materials, and the content of pyrogen is conforming to the requirement of organisms.

三种微囊与PLA的复合材料经皮肤刺激试验、皮内刺激试验、热原试验、全身急性毒性试验和细胞培养试验，结果表明，所制备的复合材料在生物学评价试验中均呈阴性反应，材料无明显毒性，材料中不存在潜在致敏性物质，所含热原含量符合生物体的要求。

Embryonic stem cell has the capability of immortalization and pleuripotent differentiation.

胚胎干细胞源于着床前的囊胚内细胞团或早期胎儿原始生殖细胞的一类未分化的多能性干细胞，具有无限增殖和多能分化的能力。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.
