| ［摘要］ 目的 探查腓肠肌变异的程度与形式, 为显微外科手术移植材料提供有用的资料。方法 10%福尔马林溶液固定尸体并进行全面解剖, 切取出变异的肌组织进行切片, H-E与镀银染色，光镜观察形态变化。结果 在该例左右禷窝处，于半膜肌止点的肌腱上各发出一条肌腱(长约2～3 cm，宽约2～2.5 cm)，该肌腱连接着一段肌腹(长约3～4 cm，宽约2～2.5 cm)，并从内上方延续到外下方斜行走，最终与腓肠肌的外侧部完全融合。两侧变异的肌肉均有独立的相应神经支配和血管系统。H-E染色的结果正常;镀银染色显示，由胫神经发出的细小神经末梢与变异肌腹的肌纤维形成正常的连接。结论 该例的两侧变异的肌肉均形成了完整的神经—运动联系单位, 这有可能使其成为潜在的移植材料而用于显微外科的创伤修复。 |

| Abstract: |
| ［Abstract］ Objective To unveil the patterns and degrees of the bilateral variations of gastrocnemius.Methods The dead human body was fixed with 10% formalin solution, and then was anatomized. Relative tissues were sectioned and stained with H-E staining and silver impregnation techniques.Results The variation pattern and degree for the right gastrocnemius was roughly similar to those for the left muscle. Furthermore, both the right and the left muscles had their own independent supplies for both nerves and blood vessels. Histological observations showed that the cell structures and nervous and vascular supplies were all normal.Conclusion Because these bilaterally varied gastrocnemius still keep their good microstructures, nerve and blood vessel supplies, the muscles may as well become a potential transplant material for surgical use. |
