摘要
目的 观察颞下颌关节血流减少对关节软骨中氨基多糖 (GAG)的影响。方法 经兔一侧颈外动脉位注射硬化剂,减少该侧关节的血流量。应用组织化学方法观察关节软骨 GAG的变化。结果 血流减少使软骨 GAG含量降低,随时间延长, GAG逐渐增加。结论 颞下颌关节血流减少可引起软骨内 GAG降低,这可能在颞下颌关节的骨关节病发生上起重要作用。
Objective The purpose of this study was to investigate the effect of blood supply decrease on glycosaminoglycans(GAG)of the cartilage in the temporomandibular joint(TMJ).Method Four rabbits were used as controls,and 16 rabbits were injected 5% sodirm morrhumate through carotid artery unilaterlally.All specimens were examimined histochemically.Result A reduction in alcian(AB)blue staining was observed after operation,a gradual increase in AB staining with blood supply restoration of TMJ tissue was observed.Conclusion The result suggests that the decrease in blood supply of the temporomnandibular jorint leads to the loss of GAG in the condylar cartilage,which may play an important role in pathogenesis of osteoarthrosis.
