角质层

Stratum corneum, stratum corneum is the natural fall off, such as hair or skin when scratching white

角质层，角质层是可以自然脱落的，如梳头时或皮肤抓痒时出现的白

Epidermal melanin reduction of stratum corneum cells, after the cuticle is transparent, and the skin will gradually turn white.

表皮角质层细胞的黑色素减少以后，角质层变得透明了，皮肤就会渐渐转白。

Things, the surface is the cuticle layer of white, this layer can be naturally break down, falling

的东西，表面是一层发白的角质层，这种角质层可以自然破裂，脱落

Each week to make above too frequently 1 time, simultaneously or uses several kinds to go to the keratose, will let the cuticle will become more and more thin, will lose water and the resistance external environment injury ability.

虽然去角质可以帮皮肤重拾光彩，但过于频繁地去除角质(例如每周做1次以上)，或同时使用好几种去角质产品，会让角质层变得越来越薄，失去储水及抵抗外界环境伤害的能力。

Tyrosinase OT47 was expressed specifically in the outer epithelial cells of the middle mantle fold, suggesting that it contributes to periostracum formation and the periostracum secretion model of P. fucata is different from previous opinion.

其中，合浦珠母贝酪氨酸酶OT47的基因特异性的表达于外套膜中褶外侧上皮细胞，可能与角质层形成有关，同时表明合浦珠母贝角质层形成可能具有其独特的细胞分泌模式。

Skin nursing shell the way for take off to throw away the periostracum strong line through an outside dint, lose the skin of periostracum protection, the immunity dint will descend, the germ easily gains an advantage but goes into, the skin that is at this time easy occurrence hair bag burning, or the face appear erythema and pimple.

皮肤护理时通过外力剥脱的办法将角质层强行去掉，失去角质层保护的皮肤，免疫力会下降，细菌容易乘虚而入，这时的皮肤就容易发生毛囊炎，或是面部出现红斑和痘痘。

In this paper, three kinds of dispersed cordaitean cuticles are described in detail from the Permian coal-bearing strata in China.

到目前为止，中国华夏植物区总共描述了4种科达植物原位角质层和3种分散角质层。

Up to now, four types of cordaitean cuticles in situ and three types of dispersed ones have been reported from the Cathaysian Flora in China.

到目前为止，中国华夏植物区总共描述了 4种科达植物原位角质层和 3种分散角质层。

Keratinous layer, the outer of epidermis, is made up of flat keratinous epithelia that have degenerated lifeless.

角质层是表皮最上一层，由角质化的扁平上皮细胞组成，它们的结构都已退化，无生命，经常脱落形成皮屑，该层含水量很少。

It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
