| 摘 要： | 目的应用荧光原位杂交（fluorescence in situ hybridization，FISH）技术检测大鼠骨骼肌挫伤后细胞间黏附分子-1（intercellular adhesion molecular—1，ICAM-1）mRNA表达。分析其与挫伤时间的关系。方法建立大鼠骨骼肌挫伤模型．分别取伤后0．5、1、6、12、18、24、30h及对照组检材。检材冰冻切片后进行FISH．激光共聚焦显微镜观察。结果大鼠骨骼肌挫伤后ICAM-1mRNA的表达6h达到峰值，18h下降至对照组的3．46倍．随后继续升高。结论大鼠骨骼肌挫伤后30h内ICAM—1mRNA的表达有一定的时间规律性．可望作为推断骨骼肌早期损伤时间的指标之一。
