The present study investigates the effects of taurine on bone markers and bone mineral density (BMD) in alcohol-fed ovariectomized (OVX) rat model. We divided twenty four rats into Sham and OVX groups. These two groups were thereafter subdivided into two groups: control and experimental diet containing 2 g/kg of taurine. BMD and bone mineral content (BMC) were estimated by PIXImus. As bone markers, we measured serum calcium, phosphorus, ALP activity, osteocalcin and urine calcium, phosphorus and DPD crosslinks value. The results were as follows: weight gain showed no significant difference and serum calcium concentration was in normal range. Urine DPD crosslink value was significantly decreased in taurine-fed group (p < 0.05). Serum ALP activity and osteocalcin levels, and urine phosphorus concentration did not show any differences among groups. Also the mineral density and content of spinal and femural bone did not show any differences among groups. However, the femur BMD was significantly increased in taurine-fed group (p < 0.05). In conclusion, taurine supplemented diets may have positive results on bone metabolism in alcohol-fed OVX rat model.
本研究旨在探讨牛磺酸对酒精灌胃去卵巢大鼠模型骨标志物和骨密度(BMD)的影响。我们将 24 只大鼠分为假手术(Sham)和去卵巢(OVX)两组。这两组再分为两组:对照组和实验组,实验组饮食中添加 2g/kg 的牛磺酸。通过 PIXImus 来评估 BMD 和骨矿物质含量(BMC)。作为骨标志物,我们测量了血清钙、磷、碱性磷酸酶(ALP)活性、骨钙素和尿钙、磷和 DPD 交联值。结果如下:体重增长无显著差异,血清钙浓度处于正常范围。牛磺酸喂养组的尿 DPD 交联值显著降低(p<0.05)。血清 ALP 活性、骨钙素水平和尿磷浓度在各组间无差异。脊柱和股骨的矿物质密度和含量在各组间也无差异。然而,牛磺酸喂养组的股骨 BMD 显著增加(p<0.05)。综上所述,牛磺酸补充饮食可能对酒精灌胃去卵巢大鼠模型的骨代谢有积极作用。
