2、骨膠原蛋白的表達(dá)情況。結(jié)果與對(duì)照組比較,質(zhì)量濃度1O~200p-g·ml_1的杜仲總黃酮能明顯促進(jìn)成骨細(xì)胞的增殖(P<0.05),但并不能顯著地促進(jìn)成骨細(xì)胞合成I型膠原蛋白。結(jié)論杜仲總黃酮能直接促進(jìn)體外成骨細(xì)胞的增殖。關(guān)鍵詞:杜仲;黃酮;成骨細(xì)胞doi:10.3969/j.issn.1004—2407.2011.04.020中圖分類號(hào):R965文獻(xiàn)標(biāo)志碼:A文章編號(hào):1004—2407(2011)04—0272—03EffectsoftotalflavonoidsofEucommiabarkontheproliferationofr
