1、駁骨煎劑促進(jìn)骨折愈合的實(shí)驗(yàn)研究更新日期:2009-08-26點(diǎn)擊:陳?!虡s勤 曹亞飛提要 為探討駁骨煎劑促進(jìn)骨折愈合的作用機(jī)理。選用體重20~30g的NIH小白鼠120只,雌雄各半,隨機(jī)分為正常組、給藥組、對照組。除正常組外,其它各組均采用定點(diǎn)手法折骨術(shù)造成小鼠右下肢脛骨中段閉合性骨折。術(shù)后7、14、21、28天分批處死小鼠,處死前48小時,經(jīng)腹腔注射同一批號0.2ml45Ca-CaCl2溶液,48小時后,斷頭取血,并解剖出左右脛骨,測定骨痂生長狀況及鈣沉積量的變化。結(jié)果顯示,給藥組與對照組,脛骨骨折處骨痂生長情況對比7天、14天時具有顯著性意義(P<0.05
2、),到28天時,骨痂重量反而有所下降。表明駁骨煎劑具有促進(jìn)骨折端的鈣沉積,加速骨折愈合的作用。而認(rèn)為這一作用是通過改善血液循環(huán),促進(jìn)血腫的吸收、機(jī)化,增加膠原的合成來實(shí)現(xiàn)的。主題詞 骨折愈合/藥物作用 駁骨煎劑/藥效學(xué) 鈣 實(shí)驗(yàn)研究 動物 小鼠中圖分類號:R289.8;R683 文獻(xiàn)標(biāo)識碼:A 文章編號:1001-6015(2000)-07-0005-02THESTIMULATIVEEFFECTOF“BOGUJIANJI”O(jiān)NFRACTUREHEALING:AnExperimentalStudyChenXi,QiaoRongqin,CaoYafei(Orthop
