【摘要】：目的　觀察某型導彈戰(zhàn)斗部對綿羊肺組織的致傷特點 ,以了解該武器引起肺組織損傷的大體、微細及超微結(jié)構(gòu)變化。方法　東北地區(qū)綿羊 45只 ,分組固定于致傷架上 ,軀體右側(cè)朝向爆心 ,呈扇形布放于距爆心不同距離處。結(jié)果　大體解剖可見肺組織有不同程度的缺損、破裂 ,伴有廣泛的出血或淤血。光鏡下可見肺毛細血管彌漫性擴張、充血和肺泡出血。出血區(qū)周圍肺組織的肺泡腔內(nèi)積有大量淡紅色的水腫液。電鏡下可見肺泡毛細血管內(nèi)皮細胞胞漿內(nèi)有較多的飲液小泡或空泡化 ,肺泡腔內(nèi)有與血漿相似的顆粒樣物質(zhì) ,Ⅰ型和Ⅱ型上皮細胞腫脹、內(nèi)質(zhì)網(wǎng)擴張 ,以至空泡化 ,核周間隙擴大等改變。結(jié)論　該型導彈戰(zhàn)斗部對肺臟損傷嚴重 ,死亡率高。因此
[Abstract]:Objective to observe the characteristics of lung injury caused by a certain missile warhead in sheep, and to understand the gross, fine and ultrastructural changes of lung tissue caused by this weapon. Methods 45 sheep from Northeast China were fixed on the injured frame. The right side of the body was oriented to the center of explosion, and the sheep were fan-shaped and placed at different distances from the center of explosion. Results at gross anatomy, lung tissue was found to have varying degrees of defect, rupture and extensive bleeding or congestion. Diffuse dilatation of pulmonary capillaries, hyperemia and alveolar hemorrhage can be seen under light microscope. A large amount of reddish edema is present in the alveolar lumen of the lung surrounding the bleeding area. Electron microscope showed that there were more vesicles or vacuolations in the cytoplasm of alveolar capillary endothelial cells, and there were granule like substances similar to plasma in alveolar lumen, type I and type 鈪，
