【摘要】：目的探讨家兔死后不同时间角膜厚度变化及其与死亡时间的关系。方法将25只家兔采用空气栓塞的方法处死后,用角膜超声测厚仪分别于死后即刻、2h、4h、8h、12h和24h测量角膜的厚度,所得数据进行统计学处理。结果即刻死亡家兔角膜厚度平均值为(357.10±6.41)μm,死亡24h角膜厚度平均增加(187.52±11.38)μm;4h内,眼睑开启与闭合对角膜厚度的增加无明显影响(F=3.5290,P0.05),8h后随时间延长,眼睑闭合角膜厚度为(429.24±8.80)μm,明显超过眼睑开启角膜平均厚度(421.40±9.53)μm,其差异有显著性意义(F=14.4480,P0.05)。眼睑闭合的角膜厚度与死亡时间关系为y=8.2418x+357.33(相关系数r1=0.8732);眼睑开启的角膜厚度与死亡时间关系为y=7.3737x+357.23(r2=0.8578)。结论在一定条件下,家兔死后24h内角膜厚度与死亡时间呈线性相关。
[Abstract]:Objective to investigate the changes of corneal thickness at different time after death in rabbits and its relationship with the time of death. Methods Twenty-five rabbits were killed by air embolism. The corneal thickness was measured immediately, 2 h, 4 h, 8 h, 12 h and 24 h after death, and the data were statistically processed. Results the average corneal thickness of rabbits died immediately was (357.10 卤6.41) 渭 m, and the corneal thickness of 24 hours after death increased by (187.52 卤11.38) 渭 m. Within 4 hours, eyelid opening and closing had no significant effect on the increase of corneal thickness (F 鈮，
