The effects of Cudrania tricuspidata (CT) extract on markers of osteoporosis were examined in ovariectomized rats. We classified 26 rats into five groups and provided a pellet chow diet and tap water throughout the 27-wk experimental period. During the last 15 wk, we added oral injections to each group as follows: sham-operated (SHAM, n=4) and ovariectomized-control (OVX, n=5) with distilled water, alendronate with 10 mg/kg/d of alendronate sodium (ALEN, n=5), CT (CT100, n=6) with 100 mg/kg/d of CT, and CT (CT300, n=6) with 300 mg/kg/d of CT. After the experimental period, blood, urine, and micro-CT images were assessed. The CT100 and OVX groups did not show any significant differences in urinary n-terminal telopeptide (NTx) (p<0.05 ), but with increases in CT concentration, the NTx level was slightly reduced. Serum osteocalcin was significantly higher in the CT groups than in all other groups (p<0.05 ). Notably, the serum calcium levels of all groups were within the normal range, but urinary calcium levels in the CT groups were significantly lower than the OVX group (p<0.05 ). In addition, the CT groups exhibited higher trabecular BMD than the OVX groups while showing similar BMD to the ALEN group (p<0.05 ). The Tb.Th of the ALEN group was lower than all other groups. Based on the overall analysis of results, CT prevented bone loss by inhibiting bone resorption and enhancing bone formation. Although alendronate showed a similar effect in preventing bone loss, it did so by solely inhibiting bone resorption, and its long-term use reportedly causes paradoxical effects such as hip fractures. Thus, for osteoporosis induced by ovariectomy, we conclude that CT extract is an effective natural treatment without severe side effects.
