Objective To investigate the change of the density and function of melanocyte in human skin autografts and normal skin, elucide the effect of change of melanocyte density in hyperpigmented process of skin autografts.

目的：通过对自体移植皮片中黑素细胞密度和功能变化的测定，进一步认识黑素细胞密度变化在自体移植皮片过度色素沉着中的作用。

MSH can cause in the melanophore the tyrosine words enhancement, causes the tyrosine the copper thing to turn the Asian copper thing, strengthens the epidermal cell to embezzle the melanin pellet, and urges the melanin pellet under the ultraviolet radiation to turn the state of oxidation from the return to original state condition, causes the skin pigmentation.

MSH能使黑色素细胞内酪氨酸话性增强，使酪氨酸的铜化物变成亚铜化物，加强表皮细胞吞没黑色素颗粒，并在紫外线照射下促使黑色素颗粒从还原状态变成氧化状态，导致皮肤色素沉着。

Results After the application of 5% nicotinamide for 4 weeks, lightening effect was obviously observed with naked eyes and the L value decreased significantly.

5％烟酰胺对UVB诱导的色素沉着有明显的抑制，它主要是通过抑制黑素细胞的增殖和黑素细胞内黑素小体的合成而发挥作用。

Each ompound eye was composed of approximately 360 ommatidia. Each ommatidium consisted of a cornea, a cone, retinula cell, rhabdom and basal cell.

3每个小眼是由1套屈光器(1个角膜和1个晶锥)、小网膜色素细胞、视杆和基细胞等几部分组成。

To investigate the co-culture of keratinocytes with MaIassezia isolates which cause the Pityriasis Versicolor with different color and to analyze the changes of cytokines associated with melanogenesis.

探讨引起花斑癣不同临床色素表现的马拉色菌与角质形成细胞共培养，导致与黑素合成相关的细胞因子的变化。

The morphology and number of lamellar bodies, perirhabdomal vacuole and pigment granule in the retinula changed with the day-night rhythm.

另外，在小网膜细胞中的板膜体、膜下储泡囊、色素颗粒等细胞器的形态和数量也随光周期呈现出规律性的变化。

With the development, both the numbers of pigment granules and the numbers and kinds of the organelles in the cell increased gradually, the diameter of the rhabdom and distance between the rhabdoms of the ommatidia increased too. The fine structure indicated that larva obtained the function of the light sensation gradually.

随着发育，幼体小网膜细胞内的色素颗粒、细胞器种类和数量、组成感杆束的微纤毛数量、感杆束的直径和间距等均有逐渐增加的趋势，表明复眼的感光结构是逐渐完善的。

Attacked by surface active agent, ocean micro-alga will be change their coloring matter for photosynthesis under the contamination of surface active agent, to result much phaeophytin-a.In addition, have assayed the surface property of the four kinds of surface-active agent.

在此基础上初步研究了表面活性剂对海洋微藻的毒性机理，找到了表面活性剂对海洋微藻细胞的攻击点是藻类的细胞膜，并且胁迫状态下的藻类细胞的光合色素组成发生变化，产生大量的脱镁叶绿素a，影响藻类的光合作用效率。

Purpose: 1. Zonular fibers are a specific form of extracellular matrix composed mainly of fibrillin what believed to be secreted by non-pigmented ciliary epithelium. The variation of fibrillin-1 distribution in lens capsule after zonule rupture was investigated in the research.

目的：1。晶状体悬韧带是一种特殊的细胞外基质，主要由睫状体非色素上皮细胞分泌产生的fibrillin-1（微纤维蛋白-1）所组成，本研究的目的是观察悬韧带离断后，晶状体囊膜中fibrillin-1的变化，探讨悬韧带离断对晶状体囊膜组成的影响；2。

The changes of density of epidermal keratinocyte and the amount and distribution of melanin in the epidermal KC were observed by histological, histochemical and autoradiographic techniques.

为了观察全厚皮片移植对过度色素沉着的影响，用豚鼠作实验对象，采用组织学、组织化学及放射自显影技术，观察豚鼠表皮内角朊细胞的密度、角朊细胞内黑色素颗粒的数量及分布形式的变化。

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.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
