目的探討人參皂甙Rg3(簡稱Rg3)與化療藥物聯(lián)合應(yīng)用對人乳腺浸潤性導(dǎo)管癌動物模型中腫瘤的生長及微血管密度的影響。方法采用人乳腺浸潤性導(dǎo)管癌癌株原位種植于16只雌性裸鼠,隨機均分成4組: 聯(lián)合用藥組即環(huán)磷酰胺(CTX) 16 mg/(kg·d)+Rg3 10 mg/(kg·d)、Rg3組[10 mg/(kg·d)]、CTX組[16 mg/(kg·d)]及對照組。自腫瘤接種第5天開始,連續(xù)灌胃55 d,脫頸處死,分別檢測腫瘤的重量,并計數(shù)腫瘤內(nèi)微血管密度(MVD)。結(jié)果Rg3組和CTX組對原位種植腫瘤的生長有明顯的抑制作用,聯(lián)合治療組抑制腫瘤生長的作用明顯優(yōu)于Rg3組,且MVD也明顯低于CTX組及對照組。結(jié)論Rg3與CTX聯(lián)合應(yīng)用能抑制人乳腺癌的生長,降低腫瘤內(nèi)的MVD。
