| Outline of Final Research Achievements |
Methods：Expression of cholinergic component in human periodontal ligament cells (HPDL) was examined by RT-PCR and immunohistochemistry. And topical application of carpronium chloride on rat calvarial defect was observed whether to promote new bone formation. Results: All of the mAchR mRNA were expressed in HPDL. Choline acetyl transferase (ChAT), Vesicular acetylcholine transporter (VAChT), Acetylcholine esterase (AChE) and various nAChR mRNA were detected in HPDL. Expression of ChAT, VAChT and AChE in HPDL was detected in immunohistochemistry. And Topical application of carpronium chloride on rat calvarial defect promoted new bone formation. Conclusion: Periodontal ligament cells have various necessary cholinergic components such as ACh synthesis, reception, degradation. These results suggest that non-neuronal cholinergic system in periodontal ligament cells and carpronium chloride may be involved in the homeostasis, wound healing and regeneration of periodontal tissues.
