Oviducts of 35 mature, white New Zealand rabbits were injured by a laser beam, using various powers from 25 to 40 W, and by a series of pulses of 1/10, 1/20 or 1/100 s duration. The contralateral oviducts served as controls and were injured at similar areas by a scalpel. The injured areas of both tubes were histologically examined at different periods from the time of injury. Enzyme histochemical studies were also carried out. The site of the laser injury was bloodless. There was a delay in the healing process of the laser side. Vessels were sealed at the area where the spot of the laser hits the vessels, but beyond that point a regular thermal damage was noted with thrombus formation such as seen in regular diathermia or scalpel injuries. Enzymatic activity of the epithelium in the vicinity of the laser-injured areas was intact. The thermal damage due to laser injury found in this study is still significant and would necessitate the use of the laser by microtechniques so as to limit the damage of oviduct tissues.
使用25至40瓦的不同功率以及持续时间为1/10、1/20或1/100秒的一系列脉冲，用激光束损伤了35只成熟的白色新西兰兔的输卵管。对侧输卵管作为对照，用手术刀在相似区域进行损伤。从损伤时刻起在不同时间段对两根输卵管的损伤区域进行组织学检查。还进行了酶组织化学研究。激光损伤部位无血。激光侧的愈合过程有延迟。在激光光斑照射血管的区域血管被封闭，但在该点之外，观察到有常规的热损伤并形成血栓，如同在常规透热疗法或手术刀损伤中所见。激光损伤区域附近上皮的酶活性完好。本研究中发现的激光损伤造成的热损伤仍然很显著，因此有必要通过显微技术使用激光，以限制输卵管组织的损伤。
