Abstract
BACKGOUND: Labisia pumila (LP) is a popular herb used by women over the past few decades. This herb has shown potentials as an alternative agent for treatment and prevention of postmenopausal osteoporosis. It was observed in previous studies that supplementation to ovariectomized rats were associated with increased bone antioxidative enzymes and reduced lipid peroxidation activity. It had also improved bone formation markers in ovariectomized rats. This study aimed to evaluate the effects of giving different forms of LP extracts on the trabecular bone microarchitecture of ovariectomised rats.
METHODS: Forty-eight female Sprague-Dawley rats were randomly divided into sham-operated (Sham), ovariectomized control (OVX), ovariectomized and given estrogen at 64.5 ?g/kg (ERT), ovariectomized and given LP aqueous extract (LPaq), LP methanol extract (LPmet) and LP ethanol extract (LPet) at 100mg/kg, respectively. Treatments were given daily via oral gavages for nine weeks. Following sacrifice, femora were dissected out for bone microarchitectural analysis using an in vitro micro-CT, which provided three dimensional informations on bone microarchitecture. RESULTS: LPaq was the most effective extract found to improve the bone microarchitectural paramaters which comprised ofBone volume fraction (BV/TV), Trabecular separation (Tb.Sp), Trabecular number (Tb.N), Connective density (Conn.dens), Structure model index (SMI) and Degree of anisotropy (DA).
CONCLUSION: LPaq was effective in protecting the bone of postmenopausal osteoporosis rat model against microarchitectural deterioration. � 2017 - IOS Press and the authors.
