Perforating wounds were made on the cranial surface of 32 teats in eight dairy cattle. The teats were distributed into eight groups with four kinds of suture patterns. The used suture patterns were Gambee in Groups A and E, continuous 2-layer (Cushing for submucosal layer, continuous horizontal mattress for intermediate layer and skin) in Groups B and F, separated 2-layer (simple continuous for mucosal layer, vertical mattress for intermediate layer and skin) in Groups C and G, and 3-layer (simple continuous for mucosal and intermediate layers, simple interrupted for skin) in Groups D and H. The wounds of Groups E, F, G and H were subjected to 3.64 J/cm2 dose of low-level laser, using a helium-neon system with an output of 8.5 mW, continuous wave at 632.8 nm. Histopathologically, healing was different between various suture patterns and between low level laser therapy (LLLT) and non-LLLT-groups. The results suggest that the 3-layer pattern was the best and LLLT could accelerate healing of perforating wounds of the teat in dairy cattle.
在八头奶牛的32个乳头的颅面制造穿孔伤口。将乳头分为八组，采用四种缝合方式。所用的缝合方式为：A组和E组采用间断垂直褥式内翻缝合法；B组和F组采用连续两层缝合（黏膜下层用库兴氏缝合法，中间层和皮肤用连续水平褥式缝合法）；C组和G组采用分开的两层缝合（黏膜层用单纯连续缝合法，中间层和皮肤用垂直褥式缝合法）；D组和H组采用三层缝合（黏膜层和中间层用单纯连续缝合法，皮肤用单纯间断缝合法）。E组、F组、G组和H组的伤口接受剂量为3.64 J/cm2的低强度激光照射，使用输出功率为8.5 mW、波长为632.8 nm的连续波氦氖激光系统。组织病理学检查显示，不同缝合方式之间以及低强度激光治疗组和非低强度激光治疗组之间的愈合情况不同。结果表明，三层缝合方式最佳，低强度激光治疗可加速奶牛乳头穿孔伤口的愈合。
