Conclusions Mast cells and peptidergic nerves have histo-morphologic relation in dorsal root ganglia.

结论在脊神经节内,肥细胞与肽能神经存在着形上的构筑关系。

The change of the control group's histomorphology was clear: the incrassation of synovial lining cells, the infiltration of Inflammatory cells and the erosion of nephelium of blood vessels on hones.

模型形变明显：关节滑膜衬里层细胞明显增厚，炎性细胞浸润，血管翳侵性骨等；而给药形变显著减轻。

To establish the animal model of re pa rative dentinogenesis and investigate the histo-morphological feature of reparat ive dentinogenesis.

建立修复性牙本质形成的动物实验模型，观察修复性牙本质形成的形特征。
