乳头形成

Methods:The mouse skin papilloma model induced by 7,12-dimethylbenzanthraene/croton oil was established,which was a classical two-stage cancer model,to observe and evaluate the anti-carcinogeneic activity of spirulina platensis.

He unbuttoned successively in reversed direction waistcoat, trousers, shirt and vest along the medial line of irregular incrispated black hairs extending in triangular convergence from the pelvic basin over the circumference of the abdomen and umbilicular fossicle along the medial line of nodes to the intersection of the sixth pectoral vertebrae, thence produced both ways at right angles and terminating in circles described about two equidistant points, right and left, on the summits of the mammary prominences.

他那双手的轨迹从参差不齐、卷缩起皱的黑色体毛的中心线——也就是自骨盆底到下腹部肚脐眼周围那一簇簇体毛，又沿着节结的中心线进而延伸到第六胸脊椎的交叉点，从这里又向两侧丛生，构成直角形，在左右等距离的两个点，即环绕乳头顶端形成的三角形收敛图形的中心线——穿行。

Therefore, in a newly designed three-dimensional cell culture system that fulfils the conditions necessary for odontoblast differentiation (Kikuchi et al. 2002), we examined whether dental papilla cells in rat mandibular incisors could differentiate into tubular dentine-forming cells.

本实验我们设计了另一种新的三维培养模型，来研究成牙本质细胞的分化，并观察大鼠下切牙牙乳头细胞能否形成管状牙本质。

If the dermal papilla in the formation of melanin in the process of a physical link in place an obstacle, it will affect the formation of melanin.

如果毛乳头在形成黑色素的过程中，某一生理环节发生了障碍，就会影响黑色素的生成。

Clinical examination revealed the presence of sixth nerve palsy in right eye and papilledema. There was enlargement of blind spot in the visual fields and red green deficiency in both eyes. Computed tomography and magnetic resonance imaging showed superior sagittal sinus thrombosis.

临床检查发现右眼第6神经麻痹和双眼视乳头水肿，双眼视野盲点扩大和红绿色觉缺失，计算机断层摄影及核磁共振扫描显示上矢状窦血栓形成，血液学检查证实抗磷脂综合征是其潜在原因。

One of the many small, platelike dermal or epidermal structures that characteristically form the external covering of fishes, reptiles, and certain mammals.

真皮与表皮交界处凹凸不平，形成许多真皮乳头和表皮突一、表皮表皮主要由角朊细胞组成，。。。

ResultsMorphological features with diagnostic value were established as follows:①Irregular or round-mesh basket type nucleolus;②Malformed nucleus and lobate nucleus with fine bridge;③Perinuclear microfilaments;④Nuclear bodies;⑤Nuclear inclusion bodies;⑥Marked cell pleomorphism arranged irregularly,like a disordered stone pavement;⑦Strange cell and/or giant cancer cell were found;⑧Peculiar papillae or cell clusters were formed;⑨Specific function structure on the surface of cell differentiated poorly.

结果 确定了具有诊断意义的形态学特征：①不规则奇形核仁或网孔状核仁；②畸形核，分叶核伴细桥－核间桥形成；③核旁微丝；④核体；⑤核包涵体；⑥细胞重度多形性，排列紊乱，似乱石铺堆；⑦出现奇形细胞和/或癌巨细胞；⑧形成奇形乳头和奇形细胞簇；⑨细胞表面特异功能结构分化不良。

Result showed that the epidermis dominant the morphogenesis changes. Mesenchymal is subdominant.β-catenin expression begin from horny placode epidermis stage and go up increasingly to peak value and maintain in hair follicle. The range of mesenchymal change is less.

结果表明，牦牛角的形态发生按照角基毛囊和角质外鞘发生与否分为5个阶段：角原基前期(Ed≤60)表皮增厚，无毛囊发生；角原基中期(Ed60~140)表皮持续增厚，有少量毛囊发生；角原基后期(Ed140~250)表皮变薄，大量毛囊发生；肉角期(≤0.5 a)真皮乳头发生；成角期(≥0.5 a)形成角质外鞘。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
