摘要
应用免疫组织化学ＰＡＰ法对亮氨酸－脑啡肽（Ｌ－ＥＮＫ）神经纤维在猫颞下颌关节（ＴＭＪ）内的分布作了研究。结果表明：ＴＭＪ囊及关节盘前后附着内均见Ｌ－ＥＮＫ阳性纤维分布，并以细枝丛状分布多见；关节囊滑膜下层的阳性纤维分布密度最高，并可见丛状结构突向滑膜层；关节囊外侧壁及关节盘前后附着内的阳性纤维分布密度相似，关节盘中部未见阳性纤维分布。
In this paper, the immunohistochemical PAP method has been used for the investigation of the distribution of leucineenkephalin (LENK) like immunoreactive fibers in feline temporomandibular joint (TMJ). The results demonstrated as follows: the TMJ capsule, anterior and posterior disc attachments all contained LENK immunoreactive nerve fibers which appeared largely as the fine plexi fibers. The density of the distribution of LENK positive nerve fibers was the highest in the subsynovium of TMJ capsule, and the plexi structures proceeding to the synovial membrane were observed. The density of the distribution in the lateral joint capsule was the same as the density of distribution in the anterior and posterior discs attachments. No LENK positive fibers were detected in the central portion of joint disc. These results indicate that there is the material basis of endogenous analgesic mechanism in TMJ and provide the neuroanatomical basis for exploring physiological functions such as analgesic, immunological and antiinflammatory effects of ENK nerve fibers in TMJ.
