摘要
兔小腿皮肤和骨损伤后，经１天、４天、７天、１４天、２１天、２８天，分别用光镜及电镜进行了观察，并计算ｒａ／ｆａ和ｃｃｎ／ａｃｎ值。结果表明：①皮肤损伤后４天，纤维母细胞内浆网扩张，７天达最高峰，ｒａ／ｆａ为２３．１３％，１４天后缩小；②皮肤损伤１天，即出现肌纤维母细胞，损伤４天胞浆内出现微丝束，７天～１４天微丝束最多；③骨损伤切口细胞数在１天最多，ｃｃｎ／ａｃｎ值最高，４天和７天也较多，１４天和２１天下降，２８天仍未降至正常。这些变化规律为损伤时间推断提供新的定量指标。
Experimental incised wounds were made on the skin and bone of rabbit’s legs under anesthesia using aseptic technique.After 1,4,7,14,21 and 28 dags,wounds were observed under light and electronic microscope,the ra/fa ratio and ccn/acn ratio were calculated.The results were as follows:(1)The endoplasmic reticulum of fibroblast expanded in 4 days after wounding,with the ra/fa ratio 23.13% at this time,and reduced 14 days after wounding.(2)The myofibroblasts appeared in l day after wounding.The microfilaments appeared in 4 days after wounding and reached a maximum gradually from the 7th to the 14th day.(3)The ccn/acn ratio at bone were the highest in lday after wounding,reduced from the 14th to the 21st day and did not drop to normal in 28 days after wounding.
