英文

Around each alveolus there are capillaries, which are very small blood vessels
在每一肺泡周圍有許多毛細管，它們是很小的血管。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。A total of 16 healthy subjects underwent bronchoscopy with bronchial mucosal biopsies and bronchoalveolar lavage ( bal ) on two occasions, in random order : once at 14 h after a 2 - h exposure to air pollution in a busy road tunnel, and once after a control day with subjects exposed to urban air during normal activities
對16名健康受試者在隨機順序下限后進行兩種處理，分別為暴露于某繁忙的公路隧道的污染空氣2小時，和選擇某一天暴露於一般繁忙程度的城市大氣中作為對照， 14小時后進行支氣管鏡下支氣管粘膜活檢和支氣管肺泡灌洗（ bal ） 。The structure of our respiratory system is like the branching pattern of a tree. the trachea as the main airway divides into smaller and smaller branches, and the smallest branches end up with small air sacs called alveoli
呼吸系統的結構好像一棵樹，氣管如樹干般分支，愈分愈小，直至在最小的支氣管末梢形成彷如氣囊的肺氣泡。分享友人
