Objectives: The purpose of this study was to evaluate the effect of Jeopgolsan (JGS) extract on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells and on factors related with fracture healing in skull fractured rat.
Methods: Experimental animals were divided into four groups: normal group without any treatment (Normal), contral group were treated orally with distilled water (Control), Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 200) and Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 400). Rats in each group except the normal group were induced fractures in the skull. ＜In vitro＞ The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity were measured to evaluate antioxidant activity. The production of nitric oxide (NO), interleukin- 1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the RAW 264.7 cells were measured to evaluate anti-inflammatory activity. ＜In vivo＞ The production of osteocalcin calcitonin, carboxy-terminal telepeptides of type II collagen (CTX II), transforming growth factor-β (TGF-β), bone morphogenetic protein-2 (BMP-2), Insulin and alkaline phosphatase (ALP) in serum of rats were measured to evaluate the effects of fracture healing at 0, 2, 4, and 6th week. X-rays were taken every 3 week from 0 to 6th week to evaluate fracture healing effect.
Results: 1. No cytotoxicity was observed. 2. DPPH and ABTS radical scavenging activity were increased in a concentration dependent manner, indicating anti-oxidant effect. 3. NO, IL-1β, IL-6, and TNF-α were not significantly changed, indicating no anti-inflammatory effect. 4. Osteocalcin, Calcitonin, TGF-β and ALP were significantly increased in the experimental groups. 5. CTX II, insulin were significantly decreased in the expermental groups. 6. Radiologic examination showed that union of fracture was promoted.
Conclusions: From above results, JGS showed significant results in factors related with fracture healing and radiologic examination. Threfore, JGS is expected to be effective in the treatment of fracture.
