Hesperidin Prevents Bone Loss in Orchidectomized Mice

Abstract

Hesperidin Prevents Androgen Deficiency-induced Bone Loss in Male Mice.

The purpose of this study was to examine whether hesperidin inhibits bone loss in androgen-deficient male mice. Male ddY mice aged 7 weeks underwent either a sham operation or orchidectomy (ORX) and were divided into five groups: a sham-operated group fed a control diet (Sham) based on AIN-93G formulation with corn oil instead of soy bean oil, an ORX group fed the control diet (ORX), a group fed the control diet containing 0.5% hesperidin (ORX + H), a group fed the control diet containing 0.7% α-glucosylhesperidin (ORX + αG), and a group fed the control diet containing 0.013% simvastatin (ORX + St). Four weeks after intervention, ORX mice showed a striking decrease in seminal vesicle weight, which was not affected by the administration of hesperidin, α-glucosylhesperidin, or simvastatin. Femoral BMD was significantly reduced by ORX, and bone loss was inhibited by the administration of hesperidin, α-glucosylhesperidin or simvastatin. Histomorphometric analysis showed that the bone volume and trabecular thickness were significantly lower, and the osteoclast number was higher in the distal femoral cancellous bone in the ORX group than in the Sham group, and these were normalized in the ORX + H, ORX + αG and ORX + St groups. These results indicate that hesperidin inhibited bone resorption and hyperlipidemia, in ORX mice, and the preventive effect was stronger than that observed in ovariectomized mice in our previous study.

Hesperidin Inhibits Osteopenia in Rats

Abstract

Hesperidin inhibits ovariectomized-induced osteopenia and shows differential effects on bone mass and strength in young and adult intact rats.

The main aim of this study was to investigate the bone-sparing effect of hesperidin, one of the main flavonoid present in oranges, in two age groups of ovariectomized female rats, compared with their intact controls. Young (3 mo) and adult (6 mo) female Wistar rats were sham operated (SH) or ovariectomized (OVX) and then pair-fed for 90 days a casein-based diet supplemented or not with 0.5% hesperidin (Hp; n = 10/group). In older rats, Hp intake led to a partial inhibition of OVX-induced bone loss, whereas a complete inhibition was obtained in younger animals. At both ages, while plasma osteocalcin concentrations were unchanged, urinary excretion of deoxypyridinoline was reduced by Hp intake, suggesting that Hp was able to slow down bone resorption. Unexpectedly, in intact young rats, Hp consumption resulted in a significant increase in bone mineral density (BMD). Indeed, 6-mo-old HpSH rats had a similar BMD to 9-mo-old nontreated SH adult rats, suggesting an accelerated bone mass gain in the young rats. In contrast, in intact adult rats, Hp did not further increase BMD but did improve their bone strength. The results of this study show a protective effect of Hp on bone loss in OVX rats of both ages without uterine stimulation and accompanied by a lipid-lowering effect. The unexpected and intriguing findings obtained in intact rats showing improved BMD in young rats and improved femoral load in adult rats merit further investigation. The bone and lipid benefits of hesperidin make it an attractive dietary agent for the management of the health of postmenopausal women.
