目的觀察中藥杜仲對去勢大鼠股骨重、礦物含量、脛骨抗彎力及血清ALP的影響。方法80只4月齡雌性SD大鼠隨機分成4組:假手術組、模型組(陰性對照組)、阿爾法骨化醇(ALF)組(陽性對照組)和杜仲組(實驗組)。除假手術組打開腹腔,暴露卵巢后即縫合外,其他3組均摘除雙側卵巢。手術后飼喂10d,陽性對照組和實驗組分別用ALF軟膠囊或鹽杜仲沖劑灌胃,1次/d,另外2組正常飼養。3個月后,取各組股骨測定股骨重、礦物含量,取脛骨測定抗彎力,取血清測定堿性磷酸酶(ALP)活性。結果與假手術組比較,模型組的股骨重顯著降低(P<0.05),而陽性對照組和實驗組股骨重無明顯變化(P>0.05);實驗組股骨礦物含量、ALP活性和脛骨抗彎力顯著高于模型組(P<0.05),陽性對照組ALP活性顯著低于模型組(P<0.05)和假手術組(P<0.01)。結論鹽杜仲可抑制骨吸收,提高骨的強度,對去勢大鼠骨質疏松具有一定的防治作用。
