- Abstract
This study aimed to investigate the impact of organic gallium (OG) on osteoporotic fracture healing in ovariectomized female Sprague-Dawley rats, as well as study the mechanisms of OG on osteoporotic fracture healing. Forty-five female Sprague-Dawley rats were divided into three groups: sham operation group (Sxas control group), ovariectomized group (Ovx), and Ovx treated with OG group (Ovx + OG). Rat femoral fractures were studied using a standardized fracture-healing model utilizing bone fixation with an intramedullary pin. Six weeks later, analyses of micro-CT, histomorphometric, RNA extraction, RT-qPCR, and serum were performed following sacrifice of all mice. In comparison with Ovx group, OG can significantly increase bone volume (BV), tissue volume (TV), BV/TV radio, bone strength, callus bony area, and as similar to BMP-2 expression. OG treatment elevated OPG messenger RNA (mRNA) and inhibited RANKL mRNA, and showed an effect on OPG/RANKL ratio. OG treatment can inhibit the expression of TNF-α and IL-6. In conclusion, current study results indicate that organic OG can positively affect the OPG/RANKL ratio and inhibit the expression of serum inflammatory cytokines; thus, it can improve osteoporotic fracture healing.
