摘要:

背景:柚皮甙能诱导骨形态发生蛋白2的基因表达,促进成骨细胞系的增殖和分化。体外细胞实验提示柚皮甙有抑制破骨细胞的形成及抗骨质疏松的作用。
目的:建立含有柚皮甙的鼠颅顶骨培养模型,观察不同剂量下柚皮甙对破骨细胞增殖分化的影响。
方法:实验选取出生4 d的SD乳鼠颅顶骨,在分别含有0,1,10,100 mg/L 的柚皮甙的培养基中培养,于培养的第1,3,7,10天测定柚皮甙对鼠颅顶骨中破骨细胞标志酶抗酒石酸酸性磷酸酶阳性细胞数及培养基中钙离子浓度的影响。
结果与结论:第1天各组间抗酒石酸酸性磷酸酶阳性细胞数及培养基中钙离子浓度无明显变化,第3,7天各组间抗酒石酸酸性磷酸酶阳性细胞数随柚皮甙质量浓度增加而减少,而培养基中钙离子浓度变化明显增加,到第10天这种变化趋势最为明显。说明柚皮甙能影响鼠颅顶骨中抗酒石酸酸性磷酸酶阳性细胞数量及其功能,并且这种作用成明显的时间剂量相关性。提示柚皮甙不仅能促进成骨细胞的增殖,同时也能减少破骨细胞的分化或加速其凋亡。

Abstract:

BACKGROUND: Naringin can increase bonemorphogeneticprotein 2 gene expression and promote the proliferation and differentiation of multipotential stem cell line. In vitro cell experiment indicates that naringin can suppress osteoclast formation and anti-osteoporosis activity.
OBJECTIVE: To prepare a mouse calvarial bone culture model containing naringin and to observe the effect of naringin with different concentrations on the formation and function of osteoclasts.
METHODS: Calvarial bone was dissected out aseptically from the 4-day-old Sprague Dawley mice, and cultured in the culture medium containing 0, 1, 10 and 100 mg/L naringin. The effects of naringin on the number of tartrate-resistant acid phosphatase-positive osteoclast marker enzyme in calvarial bone and the concentration of calcium in the culture medium were detected after cultured for 1, 3, 7 and 10 days. 
RESULTS AND CONCLUSION: After cultured for 1 day, the number of tartrate-resistant acid phosphatase-positive cells in calvarial bones and the calcium concentration in the culture medium had no difference between the groups. After cultured for 3 and 7 days, the number of tartrate-resistant acid phosphatase-positive cells was decreased and the calcium concentration was increased with the increasing concentration of naringin. At 10 days after culturing, this trend was most obvious. It showed that naringin could affect the number and function of tartrate-resistant acid phosphatase-positive cells in calvarial bones, and this effect showed a significant time- and dose-depend manner. The results show that naringin can not only promote the proliferation of osteroclasts, but also reduce the differentiation of osteoclasts or accelerate the apoptosis.
