摘要: 目的: 研究三七总苷(PNS) 对大鼠高脂血症性骨质疏松的作用。方法: 取SPF 级3 月龄未交配SD 大鼠30 只随机分为3 组, 每组10 只。正常对照组:普通饲料喂养, 蒸馏水5 mL,kg -1,d-1 灌胃;模型组:脂肪乳剂5 mL,kg-1,d-1灌胃;PNS 组:上午予脂肪乳剂5 mL,kg-1,d-1 灌胃, 下午予PNS200 mg ·kg -1,d-1 灌胃, 连续20 周。实验结束后用骨组织形态计量学方法, 测定大鼠右侧胫骨近端松质骨静态参数和动态参数, 并观察血清生化指标。结果: 与模型组比较, PNS 组游离脂肪酸(FFA)、TC、低密度脂蛋白胆固醇(LDL-C) 均明显降低(P<0.05), 高密度脂蛋白胆固醇(HDL-C) 明显升高(P<0.05);松质骨形态计量学静态参数骨小梁面积百分数(%T b.Ar)、骨小梁数量(Tb.N)、骨小梁厚度(Tb.Th) 均增加(P<0.01), 骨小梁分离度(Tb.Sp) 明显减小(P<0.01);动态参数荧光周长百分率(%L.Pm)、骨形成率(BFR/BS、BFR/BV) 均明显增加(P<0.05)。结论: 脂肪乳剂长期灌胃可导致大鼠脂质代谢紊乱, 并伴有高脂血症性骨质疏松症。PNS可显著降低血脂并促进骨的形成, 对大鼠高脂血症所致骨质疏松有一定防治作用。

Abstract: AIM: To explore the effects of panax notoginseno sides (PNS) on bone histomor phometry in rats with hyperlipidemia-inducedo steoporosis. METHODS: Thirty 3-month-old Sprague-Daw ley rats were randomly divided into three groups with 10 per group as follows. Control group was intrag astrically given distilled water at the do se of 5 mL ·kg-1,d-1 for 20 weeks ;Model group was intragast rically given lipid emulsion at the do se of 5 mL, kg -1,d-1 for 20 weeks ;PNS preventing group was intragastrically given lipid emulsion at the dose of 5 mL ·kg-1 ·d-1 in the morning and PNS at the do se of 5 mL ·kg-1 ·d-1 at afternoon for 20 weeks.At the end of the experiment, the right longitudinal proximal tibial metaphy seal parameters of rats were performed undecalcifiedly and used for bone histomo rphometry analysis. And the blood serum contents of FFA, TG, TC, HDL-C and LDL-C were measured by biochemical analy sis. RESULTS: Compared with model group, the blood serum contents of FFA, TC and LDL-C were decreased and HDL-C was increased significantly (P<0.01), the PTM cancellous bone of %Tb. Ar, Tb. Th and Tb.N were increased (P<0.01) and Tb.Sp was decreased significantly (P<0.01).The dynamic parameters in cancellous bone of %L.Pm and bone format ion rate (BFR/BS, BFR/BV) were increased(P<0.05). CONCLUSION: Long-term gastric perfusion of lipid emulsion could induce hyperlipidemia-induced osteoporosis, and PNS could partly prevent it.
