〔摘要〕 目的 研究黄瓜籽复合物对骨质疏松症大鼠的防治作用。方法 将24只雌性大鼠随机分为假手术组(Sham组)、模型组(OVX组)、雌二醇(E2)组(EV组)、黄瓜籽复合物组(QCL组)。双侧卵巢切除术建立骨质疏松症模型。术后灌胃给药12周后,用全自动生化仪测血清钙(S-Ca)、血清磷(S-P)水平;ELISA法检测E2、碱性磷酸酶(ALP)、I型胶原氨基端前肽(PINP)、I型胶原羧基端肽(CTX-I)、尿脱氧吡啶啉(DPD)水平;Micro-CT分析骨密度;HE染色观察股骨组织形态学改变。结果 与Sham组相比,OVX组S-Ca、S-P、E2、PINP及骨密度水平降低(P<0.01),ALP、CTX-I、DPD水平升高(P<0.01);与OVX组相比,QCL组、EV组S-Ca、S-P、E2、PINP及骨密度水平升高(P<0.01),ALP、CTX-I、DPD水平降低(P<0.01,P<0.05);与EV组相比,QCL组S-Ca水平升高,PINP水平降低,DPD水平升高(P<0.01)。與Sham组相比,OVX组骨小梁结构松散不规则,骨髓腔变大;与OVX组相比,EV组和QCL组骨组织形态得到改善。结论 黄瓜籽复合物能有效预防骨质疏松症,可能与提高E2、S-Ca、S-P水平,降低骨转换有关。

〔Abstract〕 Objective To study the effect of cucumber seed compound on the prevention and treatment of osteoporosis in rats. Methods 24 female rats were randomly divided into sham operation group (Sham group), model group (OVX group), estradiol (E2) group (EV group) and cucumber seed compound group (QCL group). Bilateral oophorectomy was performed to establish the osteoporosis model. After 12 weeks of intervention by intragastric administration, serum calcium (S-Ca) and serum phosphorus (S-P) levels were detected by automatic biochemical analyzer; E2, alkaline phosphatase (ALP), collagen I amino terminal peptide (PINP), collagen I carboxyl terminal peptide (CTX-I) and deoxypyridinoline (DPD) levels were detected by ELISA; bone mineral density was analyzed with Micro-CT; the morphology of femur was observed by HE staining. Results Compared with the Sham group, the levels of S-Ca, S-P, E2, PINP and bone mineral density in the OVX group decreased (P<0.01), the levels of ALP, CTX-I and DPD increased (P<0.01). Compared with the OVX group, the levels of S-Ca, S-P, E2, PINP and bone mineral density in the QCL group and EV group increased (P<0.01), the levels of ALP, CTX-I and DPD decreased (P<0.01, P<0.05). Compared with the EV group, the S-Ca level increased, the PINP level decreased and the DPD level increased in the QCL group (P<0.01). Compared with the Sham group, the trabecular bone structure of the OVX group was loose and irregular, the bone marrow cavity became larger. Compared with the OVX group, the morphology of the EV group and the QCL group have been significantly improved. Conclusion Cucumber seed compound can effectively prevent osteoporosis, which may be related to up-regulate E2, S-Ca, S-P levels and down-regulate bone turnover.

骨质疏松症是一种非代谢性骨病,其特点是由于骨蛋白和矿物质含量的过度流失而导致骨密度和强度下降[1]。绝经后骨质疏松症(postmenopausal osteoporosis, PMOP)是原发性骨质疏松症中最常见的,而且PMOP的发病率正在迅速增加[2]。随着中医学的发展,中药和天然植物活性成分对实验性PMOP显示良好的药效作用[3],因此,寻找一种天然的安全有效的治疗PMOP的手段具有重要意义。

黄瓜籽为葫芦科植物黄瓜的干燥成熟种子。黄瓜籽富含脂肪酸、糖类、苷类、植物甾醇、矿物质元素等丰富的化学成分[4]。《中华本草》中记载其具有续筋接骨、祛风、消痰的功效,主治骨折筋伤、风湿痹痛[5]。生菜是一种绿色多叶蔬菜,含有丰富的钾、钠、钙、镁等微量元素和其他植物化学物质[6]。據《中华本草》中介绍,生菜籽具有通乳汁、利小便、活血行瘀等功效,主治乳汁不通、小便不利、跌打损伤、瘀肿疼痛等[5]。……
