ABSTRACT

Objectives The object of this study was to assess the effect of Gyejibokryunghwan (GBH) on anti-oxidant and anti-inflammatory activities in RAW 264.7 cells and on factors associated with fracture union in tibia-fractured rats. Methods The 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging activity was measured to assess anti-oxidant activity. The production of nitric oxide (NO), interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the RAW 264.7 cells were measured to assess anti-inflammatory activity. The production of osteocalcin, calcitonin, carboxy-terminal telepeptides of type II collagen (CTXⅡ), transforming growth factor-β (TGF-β), bone morphogenetic protein-2 (BMP-2) in serum of tibia-fractured rats were measured to assess the effects of fracture union. X-rays were taken every two weeks from 0 to 4th week to assess fracture union effect. Results DPPH radical scavenging activity of GBH was increased according to concentration of GBH in RAW 264.7 cell. NO, prostaglandin E2 (PGE2), IL-6, IL-1β and TNF-α were significantly decreased, indicating anti-inflammatory effect. Osteocalcin, calcitonin, TGF-β were significantly increased in the experimental groups. CTXⅡ was significantly decreased in the experimental groups. BMP-2 was not significantly changed in the experimental groups. The X-ray showed that the experimental group has better healing effects on tibia-fractured rats than control group. Conclusions From above result, GBH has an effect on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells. GBH showed significant results in factors related with fracture union and radiologic examination. In conclusion, GBH can help fracture union and it well be expected to be used actively in clinics.
