Analysis of appearance of the pain and its factor at synovial membrane in the temporomandibular joint

首先，我们从胚胎期开始观察大鼠颞下颌关节的滑膜，以清除正常结构。其次，我们观察了由大开口形成的大鼠颞下颌关节滑膜的异常。除血管增生外，正常与异常的滑膜在组织学上无明显差异，但能明确正常颞下颌关节滑膜的发育及细节结构。我们将继续进行本研究，以建立异常模型，明确颞下颌关节紊乱时滑膜疼痛的表现及其影响因素

Firstly, we observed synovial membrane in rat temporomandibular joint from embryologic stage for normal structure cleared. Secondly, we observed abnormal synovial membrane of rat temporomandibular joint which made from large open mouth. There were no histological change between normal and abnormal synovial membrane except hyperplasia of blood vessel, but we could clarified the development and the detail structure of normal synovial membrane in temporomandibular joint. We will continue this study to devise making abnormal model, and clarify appearance of the pain and its factor at synovial membrane in the tenporomandibular disorder
