下颌前伸后大鼠颞下颌关节盘Ⅰ型胶原免疫组织化学研究

Immunohistochemical Study on the Temporomandibular Articular Disc in Young Growing Rats After Functional Mandibular Advancements

应用免疫组织化学的方法，对幼年ＳＤ雄性大鼠功能矫形前伸下颌后颞下颌关节盘Ⅰ型胶原的变化进行研究。结果显示，对照组大鼠关节盘的染色反应强度随着年龄的增加而逐渐加深，实验组关节盘的染色反应强于对照组。

In the present experiment the type Ⅰ collagen of discs was investigated with immunohistochemistry in the young growing SD rats after the mandible protruded functionally. The experimental evidence showed that the immunohistochemical staining reactions accentuated with age changed in control group discs, and the immunohistochemical staining reactions in experimental group were intenser than in control group. It indicated that the discs synthesized higher contents of type Ⅰ collagen after the disc accepted more functional stimuli in the experimental group.
