【摘要】：目的　研究迅速減壓對兔肺超微結(jié)構(gòu)的影響。方法　將 30只新西蘭白兔隨機分為慢上升減壓組和迅速減壓組 ,用透射電鏡觀察兔肺超微結(jié)構(gòu)的變化。結(jié)果　迅速減壓組兔肺Ⅰ型及Ⅱ型肺泡細胞膜結(jié)構(gòu)不清 ,細胞間連接松散 ,Ⅱ型肺泡細胞內(nèi)發(fā)現(xiàn)腫脹的線粒體及擴張的粗面內(nèi)質(zhì)網(wǎng) ,肺泡壁毛細血管擴張充血 ,血管內(nèi)皮細胞腫脹 ,通透性增加。當減壓峰值大于 9 8kPa(10 0 0mmH2 O)時變化更為明顯。結(jié)論　迅速減壓能引起肺臟損傷 ,減壓峰值越大 ,結(jié)構(gòu)破壞就越重。
[Abstract]:Objective to study the effect of rapid decompression on the ultrastructure of rabbit lung. Methods Thirty New Zealand white rabbits were randomly divided into slow ascending decompression group and rapid decompression group. The ultrastructure of lung was observed by transmission electron microscope. Results in the group of rapid decompression, the structure of alveolar membrane of type I and type 鈪，
