摘 要:目的:研究含淫羊藿总黄酮大鼠血清对体外培养成骨细胞(ROB)增殖和分化的影响。方法:将淫羊藿总黄酮(TFE)以0.1,1,10,100μg.mL-14种质量浓度、含淫羊藿总黄酮大鼠血清(SRAT)以2.5%,5%,10%3种质量浓度分别加入新生大鼠颅骨成骨细胞培养液中,研究它们对细胞增殖和分化成熟的影响。细胞增殖采用MTT法进行分析,细胞分化是于培养第4,8,12,20天分别检测碱性磷酸酶活性(比色法)、骨钙素分泌量(放射免疫法)、钙盐沉积量(比色法)和矿化结节(组织化学法)等。结果:TFE 4种质量浓度均对ROB细胞增殖和分化无明显影响,2.5%和5%SRAT则表现出强烈的刺激细胞增殖活性并显著提高碱性磷酸酶活性、骨钙素分泌量、矿化结节数和钙盐沉积量。结论:淫羊藿总黄酮代谢产物强烈刺激成骨细胞的增殖并促进其分化成熟,说明淫羊藿总黄酮代谢产物具有抗骨质疏松的活性。Objective: To investigate the effects of total flavonoid extract of Epimedium sagittatum (TFE) on the proliferation and differentiation of newborn rat calvarial osteoblasts (ROB). Method: TFE was supplemented into the culture medium of ROB at 0. 1, 1, 10 and 100μg · mL^-1 respectively. The serum of rats administered TFES (SRAT) was also added into the medium in a parallel treatment at 2. 5% , 5% and 10% respectively. Their effects on cell proliferation and differentiation was studied by MIT and the analysis of osteogenic differentiation marks. Result: TFE had no appreciable and on cell proliferation and differentiation at any concentration. However, 2. 5% and 5% SRAT stimulated cell proliferation strongly and, 5% SRAT significantly promoted the maturation and function of osteoblast by improving the alkaline phosphatase activity, osteocalcin secretion, calcium deposition and the number of mineralized nodular structures. Conclusion: The metabolites of TFE should be the anti-osteoporosis constitutes of Epimedium sagittatum.
