2、組與正常對照組每天灌胃等量的蒸餾水,連續(xù)給藥5周后測定小鼠的訓(xùn)練成績、記憶成績及血清SOD、ACHE和腦組織MDA的含量變化。結(jié)果實驗組的訓(xùn)練成績顯著(P<0.05),測試成績極顯著(P<0.01)好于、血清SOD、ACHE活力極顯著(P<0.01)高于、腦MDA含量極顯著(P<0.01)低于模型對照組;與正常組比,除ACHE偏高外,其余各指標相近。結(jié)論鉤藤散能提高抗氧化能力,降低自由基含量,增強膽堿能神經(jīng)系統(tǒng)功能,從而防止衰老?!娟P(guān)鍵詞】D-半乳糖;鉤藤散;衰老;小鼠【Abstract】ObjectiveToobservetheeffectsofGoute
