Effects of Yuhyangjeongtong-san on Fracture Healing in Rats

The purpose of this study is to determine the effect of Yuhyangjeongtong-san on the recovery of tibial fractures in rats. Methods: In this study, osteocalcin and Calcitonin, CTX-2, TGF- and BMP-2, which are used as indicators of bone formation, were analyzed after hematologic fractures using experimental rats. In addition, the fracture union process was confirmed using X-rays. Results: Osteocalcin, Calcitonin and BMP-2 showed a significant increase compared with the control at 4 weeks. CTX-2 and TGF- showed a significant increase compared with the control at 3 weeks. On X-ray, YJS treated group, as the experiment progressed, the boundary line became blurred, the bone outline was clearly visible, and the fracture recover was progressing.
