( 5 ) effects on mouse cerebrum cortex of so2 challenge : we found no pathological changes of mouse cerebrum cortex challenged by so2 by he staining and tem observation, in vitro tests of so2 derivatives challenge showed that : ( 1 ) so2 derivatives has significant toxicity on mouse spleen cells, the lc50 of 4h and 24h exposure is 1. 1293 mmol / l and 1. 3777mmol / l respectively
二氧化硫代謝衍生物體外實驗結果表明: （ l ）二氧化硫代謝衍生物對小鼠脾細胞具有明顯的細胞毒性作用，染毒4小時和24小時細胞的半數存活抑制濃度lcs 。分別為1 . 12932r以mol幾和1 . 37777 ~ ol幾。 -
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。
