The relationship between the cardiotonic effects and the cardiac sarcolenmmal Na〓, K〓-ATPase activities by strophanthidin in isolated guinea-pig heart

本研究通过对正常和衰竭的离体豚鼠心脏和急性分离的心室肌细胞的研究，在器官水平分析了毒毛旋花子苷原的强心作用及其与Na〓，K〓-ATP酶活性间的关系，在细胞水平分析了毒毛旋花子苷原提高心肌收缩力的可能机制。

Xinjiang Daye'is higher than male sterile lines. 2、The pistil characters of the male sterile plants BC1-2、BC1-19、BC1-21、BC1-22、BC1-23 are improved. Hairy cells of stigma of the male sterile plants enwrap loose mastoid cells. The area of mastoid cells exterior is larger. Hairy cells of stigma of the male sterile plants are longer and abduction.Their Style is larger and wide. The cubage of the epidermal cell is larger and the arrangement of passage cells is tight.

BC1-2、BC1-19、BC1-21、BC1-22、BC1-23的雌蕊的性状得到改良，改良的杂交后代不育株的柱头毛状体细胞将中心的乳突细胞包裹较疏松，乳突细胞明显突起且裸露面积较大，毛状体细胞较原不育系MS-4的相对长而外展且分泌物较多，；改良的杂交后代不育株的花柱较原不育系的花柱宽且长，表皮细胞的体积较大，通道细胞排列较紧密。

The results indicate that all of the peltate glandular hairs and head glandular hairs are from an origin—protoderm on the leaf primordium and young leaf, which outgrows on leaf surface and increase radial broad and form the initial cells of the glandular hairs.

研究结果表明，唇形科的腺毛不论是盾状腺毛类还是头状腺毛类，在发育上都是单起源的，即所有的腺毛均起源于叶原基或幼叶上的原表皮细胞。该细胞在叶表面向外突出生长，径向加宽，形成腺毛原始细胞。

Methods 12 guinea pigs of 20 months with 3 cm×3 cm hair sheared from their backs were divided into control group and experimental group. Rhodosin and deer serum preparation was besmeared on the skin of guinea pigs in experimental group, and cosmetic matrix was besmeared on the skin of animals in control group for 60 d. The distribution of type Ⅲ collagen was observed with Sirius red staining and HE staining. The fission index of the cells of stratum basale, the thickness proportion of stratum corneum to epidermis, the volume density of the collagen fibers and small blood vessel in dermis, the number of fibroblasts in aging skin were meassured with technique of sterology.

背部被剪去3 cm×3 cm毛的12只20月龄豚鼠被随机均分为给药组和对照组，给药组涂抹红鹿制剂，对照组涂抹化妆品基质，连续涂抹60 d；应用天狼猩红、HE染色和体视学技术分别观察和测定老化皮肤中Ⅲ型胶原的分布、表皮基底层细胞的分裂指数、角质层同表皮厚度的比例、真皮胶原纤维和微血管的体密度和成纤维细胞的数目。

According to the shape of head, the glandular hairs were divided into capitate and pehate glandular hairs.

根据腺毛头部形状可把腺毛分为盾状腺毛和头状腺毛，二者均发生得很早，它们的原始细胞都来源于原表皮，一般在茎尖第1和第2片叶原基的原表皮细胞以及茎的1～2节间原表皮细胞中开始发生。

That GER cells which are likely hair cell progenitors could be cultured in vitro and generate stereociliary bundle-like structure when forced to express Hath1 suggests that the misexpression of Hath1 probably can induce the predifferentiation of pure hair cell progenitors into hair cells in vitro.

GER细胞作为毛细胞前体细胞可以实现体外原代培养，在Hath1基因重表达情况下，部分细胞的表面可见不成熟的纤毛样结构，提示Hath1基因也许可以诱导离体培养下的纯的毛细胞前体细胞向毛细胞的初步分化。

Many factors may be involve in the course. To investigate the regulation activity of mesenchymal cells to differentiation of epithelial cells from hair follicle and to study its differentiation property, mesenchymal cells gel was made by nubby dermal papilla cells, free dermal papilla cells, skin fibroblasts. Skin keratinocytes and epithelial cells from hair follicle were inoculated on the gel surface and cultured in air-liquid interface. Three-dimensional model of DPC using to induce epithelial cells differentiation is built in vitro.

为了进一步研究毛囊细胞间的相互作用，探讨毛囊间质细胞对毛囊上皮细胞分化的调节作用，研究毛囊上皮细胞的分化特性，我们利用团块状的毛乳头细胞，游离分散的毛乳头细胞或皮肤成纤维细胞制成间质细胞胶原凝胶，表面接种皮肤角质形成细胞或毛囊上皮细胞，进行气-液界面培养，在体外建立了毛乳头细胞诱导毛囊上皮细胞分化的立体模型。

Both of them originated from the protodermal cells and formed four cells through two successive periclinal divisions.

两类表皮毛的原始细胞均起源于叶原基或幼叶的原表皮细胞，经过两次垂周分裂形成四细胞。

Objective To investigate the mechanisms of hair cell generation and regeneration, a primary culture system of utricular sensory epithelial cells of the rat was established.

目的 建立大鼠椭圆囊感觉上皮细胞( utricular sensory epithelial cell， USEC )的原代培养体系，为研究毛细胞再生机制提供大量来源一致的细胞。

When the concentration of NaCl was further increased to 8%, the cells of P. chrysosporium were deformed and plasma was completely vacuolated, indicative of a severe damage of P. chrysosporium. The DNA similarity was reduced to blow 67% and the rate of abnormal cells was increased to about 90%. The cells of P. chrysosporium thus essentially lost their original structure and function.

chrysosporium的结构与功能产生不良影响；NaCl浓度≥8%可对黄孢原毛平革菌产生严重损伤，细胞变形严重，空泡化，DNA相似度降至67%以下，异常细胞量约90%，表明此浓度范围可使黄孢原毛平革菌基本丧失了原有的结构与功能。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
