In submicroscope , respiratory cell is flat , there are microvillus on it s surface , and lots of chondriosome in the cytoplasm and some gdgi 10 complex distribute near the nuclear . the other cell organ has not been found 电镜下呼吸细胞扁平，表面有微绒毛，胞质中分布有一定数量的线粒体，在核旁分布有高尔基复合体，其它细胞器则少见。
The multivesiculae bodies , as well as the rough and smooth endoplasmic reticulums , are considered as the sources of new membranes . mitochondria provide energy not only for the degradation of microvilli , but also for the resynthesis of the photoreceptor membrane 微绒毛合成时的膜源由粗面内质网和滑面内质网共同提供；多泡体也能起膜源作用。
The results showed that the lumen of small intestine was lined by the simple columnar epithelium , most of the cells were high columnar absorbing ones with abundant developed microvilli 结果表明，中华鳖小肠黏膜上皮为单层柱状上皮，以高柱状吸收细胞为主，具有发达的微绒毛、线粒体、粗面内质网和膜包小囊泡，其结构的发达程度已接近高等哺乳动物和鸟类。
During dark adaptation , the rhabdomal figures are regular , the distal pigment granules and proximal pigment granules are concentrated in the distal of crystalline tract and the proximal rhabdom respectively , and while retinular pigment granules are lacked in proximal of ommatidium 暗适应时，感杆束外形规则，微绒毛排列整齐，远端色素则集中于小眼的远端，近端缺乏小网膜细胞色素，仅有近端反光色素分布。
The lysosome system and the other cells amongst retinular cells carry out the breakdown of microvilli . the former includes coated vesicles , lysosome , lamellar bodies and oil droplets ; and the latter include the hemocytes , proximal reflecting pigment cells and nerve glial cells 微绒毛降解过程通过自身的溶酶体系统(包括被膜小泡、溶酶体、板膜体和脂滴)和小网膜细胞之外的其它细胞(如血细胞、近端反光色素细胞和神经胶质细胞)共同完成。
During spawning , the structure of oviduct is obviously affected . before laying eggs , there are many secretions in oviduct and lots of microvilli at the surface of epithelial cells . the clear cells contain lots of mitochondria , endoplasmic reticulums and golgi complexes 日本沼虾产卵过程对输卵管结构产生显著的影响，产卵前，管腔内有很多分泌物，管壁上皮细胞表面有大量微绒毛，细胞内细胞器如线粒体、内质网、高尔基体等含量丰富，细胞核形态正常。
We also investigated the pathological changes of mouse liver , thymus and cerebrum cortex challenged by so2 inhalation by in vivo tests . we studied the apoptotic induction on mouse spleen cells and cytotoxicity of human embryo lung fibroblasts of so2 derivatives by in vitro tests . in vivo tests of sulfur dioxide inhalation showed : ( 1 ) effects on mouse lung of so2 challenge : we found no significant apoptotic changes induced by so2 inhalation but obvious pathological changes of lung with vacuolating of osmiophilic multilamellar bodies which maybe related with the decrease of surfacant and decrease of microvillus of type ii alveolar cells ; we also found thickening of part of basement lamina between type i alveolar cells and capillary endothelium cells which may inhibit the dispersion of oxygen and contribute to lung dysfunction 二氧化硫熏气染毒的体内实验结果表明，在本次实验的浓度范围内( 56mg m ~ 3 、 112mg m ~ 3 、 168mg m ~ 3低、中、高三个浓度) ： ( 1 )通过透射电镜、 dna凝胶电泳分析和流式细胞分析发现二氧化硫吸入染毒一周对小鼠肺脏没有明显的凋亡诱导作用，但通过透射电镜观察发现二氧化硫可引起肺脏明显的超微结构改变，引起型肺泡上皮细胞板层体空泡化，微绒毛减少，线粒体致密化或肿胀变性；肺泡血管内皮细胞和型肺泡上皮细胞之间基膜增厚，使氧气弥散功能出现障碍，从而降低肺功能。
The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment . ( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma , compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index . the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation 结果显示： ( 1 )人精子mr能够诱发去透明带金黄地鼠卵母细胞中皮质颗粒的胞吐，并引起卵母细胞膜表面微绒毛形态和数量发生改变； ( 2 )皮质颗粒胞吐后，其内容物可结合到卵膜表面； ( 3 )抗mr抗血清预处理精子可抑制精子与卵子的结合与融合，使受精率、穿透指数和结合指数下降，并均有剂量依赖性。以上结果提示，人精子mr在受精过程中起重要作用，其主要作用可能是介导精-卵膜融合并促进卵母细胞的活化。
Nine days later , microvilli of epithelial cell begin to increase , and secretions among mocrovilli also can be seen , and hi the cytoplasm the amount of organelle increases gradually . but comparied with that before laying eggs , the amount of microvilli , secretions , types and amount of organelle are few too 产卵后第9天，上皮细胞游离面微绒毛开始增多，微绒毛中可见分泌物存在；上皮细胞内细胞器数量逐渐增加，细胞核正常；但细胞结构与产卵前相比仍有较大差别，其微绒毛及分泌物含量，细胞器种类和数量均较产卵前少。
We used four different wavelength light including red light ( 750nm ) , yellow light ( 580nm ) , green light ( 560nm ) , blue light ( 400nm ) to stimulate four different groups compound eyes . then the ultrastructures of the compound eyes of each group were observed under electron microscope . the results showed the fine structure of the photoreceptor , the diameter of rhabdom , the dimension of perirhabdom vacuole , the number of pinocytotic vesicle below the microsvilli , the location of pigment granules , the emergence of lamellar bodies and lysosomes in cytoplasm , were different in different light adaptation 二、不同光照条件下复眼超微结构的变化三疣梭子蟹经过12h暗适应后，在不同波长的红光( 750nm ) ，黄光( 580nm ) ，绿光( 560nm ) ，蓝光( 400nm )照射下，其光感受器的小网膜细胞和感杆束的形态和超微结构呈现较大的区别，感杆束的形态、细胞内的胞器随不同波长光的适应而发生变化，在红光下感杆束直径最大，微绒毛排列整齐，在蓝光下感杆束直径最小，微绒毛最凌乱。
