title: [Distribution of calcitonin gene-related peptide-like immunoreactive fibres in the temporomandibular joint of rat].
abstract: OBJECTIVE
  To observe the distribution of calcitonin gene-related peptide-like immunoreactive (CGRP-LI) nerve fibres in rat's temporomandibular joint (TMJ).
  
  
  METHODS
  The avidin-biotin-peroxidase complex method and image analysis were employed to detect CGRP-LI nerve fibres in frozen sections of TMJs in eight rats.
  
  
  RESULTS
  CGRP-LI nerve fibres were plentifully distributed in TMJs except the central disc band and bone, mainly in the periphery of blood vessels, especially arteries. Density: anterior disc attachment and capsule, (454.6 +/- 72.8) mm(2); posterior portion, (302.7 +/- 43.4) mm(2); lateral portion, (240.2 +/- 23.6) mm(2); medial portion, (229.6 +/- 25.0)mm(2); and peripheral portion of disc, (202.4 +/- 35.2) mm(2).
  
  
  CONCLUSIONS
  CGRP-LI nerve fibres were widely distributed in rat TMJ and were a part of trigeminal sensory nerve. Density was highest in anterior disc attachment and capsule.
