The stress-strain relation of oral mucosa of dogs was measured before and 6 weeks after surgical removal of mucosa. Both CO2-laser evaporation and excision were employed. Measurements were done with a miniature tensile tester, especially developed for this purpose. The load-strain ratio of the healed mucosa was proportional to the histologically determined thickness of the healed epithelium and scar tissue together. Laser evaporation caused a 75% increase, excision almost a threefold increase of the load-strain ratio compared with untreated tissue.
在手术切除犬口腔黏膜前及切除后6周，测量了犬口腔黏膜的应力-应变关系。采用了二氧化碳激光汽化和切除两种方式。测量使用的是专门为此研发的微型拉伸测试仪。愈合黏膜的负荷-应变比与组织学测定的愈合上皮和瘢痕组织总厚度成正比。与未处理组织相比，激光汽化使负荷-应变比增加了75%，切除则使其增加了近三倍。
