2、含量不同分成6組,在50gCemex'XL骨水泥粉末中分別加人0,10,50,100,500,l000mg阿倫磷酸鈉,依次命名為Go-G。組。通過電鏡觀察各組成骨細(xì)胞樣MG一63的黏附能力,MTI"比色法測定吸光度值,堿性磷酸酶試劑盒測定堿性磷酸酶(alkalinephosphataseactivity,m(P)活性,Annexin-V-FITC凋亡檢測試劑盒測定凋亡率,相差顯微鏡觀察骨礦化情況。結(jié)果:各組MG一63細(xì)胞黏附能力良好;與G。組相比,G。一G。組抑制細(xì)胞凋亡,G;組促進(jìn)細(xì)胞凋亡和抑制細(xì)
3、胞增殖(po.05)。結(jié)論:在50g骨水泥粉末中加入阿倫磷酸鈉不超過s00rngj(寸成骨細(xì)胞無毒性。【關(guān)鍵詞】阿倫磷酸鈉;二磷酸鹽;含量;骨水泥;成骨細(xì)胞Effectofalendronate..10adedbonecementonosteoblastSONGDeye,NIJiangdong,MAOXinzhan,DINGMuliang(DepartmentofOrthopaedics,SecondXiangyaHospita
