Preventive effect of Total ethanolic extract of Butea monosperma on bone loss in osteopenic rats
Abstract
Aim: The intent of the study was to assess the bone conserving effect of Butea monosperma total extract (BTE) prepared from the stem-bark, in ovariectomy (Ovx)-induced bone loss in Sprague Dawley (SD) rats.
Methods: Sprague-Dawley rats were ovariectomized (Ovx) and BTE treatment with three different doses (100mg, 250mg and 500mg/kg body weight) commenced a day after Ovx and continued for 12 weeks. Skeletal parameters including trabecular and cortical bone microarchitecture, bone mineral density, bone mineral content, biomechanical strength, bone turnover markers (serum procollagen 1 N-terminal propeptide/ P1NP and cross-linked C-telopeptide of type I collagen/CTX-1), new bone formation rate (periosteal bone formation rate and mineral apposition rate), and expression of osteogenic genes were assessed. Estrogenicity of BTE was assessed by studying uterus at the end of the treatments.
Results: Ovx rats treated with BTE prevented the alterations in trabecular and cortical microarchitecture, maintained bone mineral density, bone mineral content, and increased bone biomechanical strength in comparison with Ovx rats. Treatment of BTE also enhanced new bone formation rate, increased the serum bone formation marker (P1NP), decreased the serum bone resorption marker (CTX-1), and upregulated the osteogenic genes in bones. BTE was devoid of estrogen-like effect in uterus.
Conclusion: BTE protects against Ovx-induced bone loss by inhibiting bone resorption and increasing new bone formation. The most effective bone conserving dose of BTE was 250mg/kg. This study demonstrates the potential of BTE in preventing/delaying osteoporosis development in postmenopausal women.
