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
電鏡下呼吸細胞扁平，表面有微絨毛，胞質中分佈有一定數量的線粒體，在核旁分佈有高爾基復合體，其它細胞器則少見。 -
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
二氧化硫熏氣染毒的體內實驗結果表明，在本次實驗的濃度范圍內（ 56mg m ~ 3 、 112mg m ~ 3 、 168mg m ~ 3低、中、高三個濃度） ： （ 1 ）通過透射電鏡、 dna凝膠電泳分析和流式細胞分析發現二氧化硫吸入染毒一周對小鼠肺臟沒有明顯的凋亡誘導作用，但通過透射電鏡觀察發現二氧化硫可引起肺臟明顯的超微結構改變，引起型肺泡上皮細胞板層體空泡化，微絨毛減少，線粒體緻密化或腫脹變性；肺泡血管內皮細胞和型肺泡上皮細胞之間基膜增厚，使氧氣彌散功能出現障礙，從而降低肺功能。 -
Nonrespiratory cells have microvillus and lots of lipid droplet in the cytoplasm
非呼吸細胞的表面有微絨毛，胞質中有脂肪滴。 -
During light adaptat ion the arrangement of microvillus in the rhabdom was in disorder, and the diameter of rhabdom was reduced. at the same adaptation the area of the perirhabdomal vacuole was reduced and the number of the multi vesicular body was increased. besides that the d i str i but i on and the amount of the p i gment granule, the lamellar body were influenced by light adaptation
光適應時感桿束的微纖毛的平均直徑膨大，排列零亂，感桿束的平均直徑減小；膜下儲泡囊平均直徑減小；小網膜的細胞質中胞飲泡和小囊泡數量較多；多囊體的平均直徑減小，數量較少；板膜體較少，色素顆粒多，分佈於細胞的各個層面。 -
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
結果顯示： （ 1 ）人精子mr能夠誘發去透明帶金黃地鼠卵母細胞中皮質顆粒的胞吐，並引起卵母細胞膜表面微絨毛形態和數量發生改變； （ 2 ）皮質顆粒胞吐后，其內容物可結合到卵膜表面； （ 3 ）抗mr抗血清預處理精子可抑制精子與卵子的結合與融合，使受精率、穿透指數和結合指數下降，並均有劑量依賴性。以上結果提示，人精子mr在受精過程中起重要作用，其主要作用可能是介導精-卵膜融合併促進卵母細胞的活化。
