摘要
采用ATP酶染组化技术,结合光镜动态观察了豚鼠角膜碱烧伤中郎格罕细胞(LC)的变化。发现碱烧伤后第4天角膜LC开始增加(中央部42.2±2个/mm^2,周边部120.8±8个/mm^2),11 d达高峰(中央部143.5±4个/mm^2,周边部219.5±11个/mm^2),2周后开始下降(中央部53.5±15个/mm^2,周边部133.7±12个/mm^2)。提示LC是一类在某些因素刺激下可移动的细胞群。并讨论了LC在角膜碱烧伤发病机制和损伤修复中的作用。
We observed dynamically the alteration of LCs on the ocular surface of experimental cornael burns in guinea pigs with the use of the technique of ATPase staining and histological microscope. The results showed that LCs began to increase on day 4 (central corneal 42.2±2.0/mm2, limbus 120.8 ±8.0 /mm2), reached a peak on day 11 (central 143.5 ±4.0/mm2, limbus 219.5± 11.0/mm2) and decreased 2 weeks later (central 153.5 ± 15.0/mm2, limbus 133.7 ±12.0/mm2). These findings suggest that LCs are removable under some sti-muli. The role of LCs in the pathogenesis and repariment of corneal epithelial alkali burns was also discussed.
