功能矫形前伸下颌后大鼠翼外肌胰岛素分布的免疫组织化学研究

目的：研究功能矫形治疗工外肌内胰岛素的分布规律和定位。方法：采用免疫组化ABC法，对青春生长期雄性SD大鼠功能矫形前伸下颌后翼外肌内胰岛素的分布和规律定位和半定量研究，结果：翼外肌内胰岛素定位于肌细胞膜上；功能矫形前伸下颌后，大鼠翼外肌内胰岛素的分布增加。结论：胰岛素在功能矫形前伸下颌后翼外肌的适应性改建中有重要作用。

An Immunohistochemical Study of Distribution of Insulin in Lateral Pterygoid Muscle after Functional Mandibular Protrusion in Rats

Objective:The aim of this study is to investigate the effects of insulin on the lateral pterygoid muscle of growing rats after the functional mandibular protrusion.Methods:An immunohistochemical (the ABC method) method was used to detect the location and distribution of insulin in the lateral pterygoid muscle of rats. Results:1. Insulin located in the cell membrane of the lateral pterygoid muscle. 2. The distribution of insulin in the lateral pterygoid muscle of rats was enhanced after the functional mandibular protrusion. Conclusion:Insulin may play an important role in adaptive remodeling of the lateral pterygoid muscle after the treatment of functional mandibular protrusion.
