摘要:
目的 ·制备培美曲塞脂质体,观察其对乳腺癌细胞MCF-7及荷瘤裸鼠模型肿瘤的抑制作用。方法 ·采用薄膜分散法制作脂质体,CCK-8法检测其对MCF-7细胞的抑制作用;建立Balb/c裸鼠荷瘤模型,通过尾静脉给药以检测其抑瘤作用。结果 ·培美曲塞脂质体可抑制MCF-7细胞增殖,当培美曲塞浓度分别为0.20、0.40和10.00 μg/mL时,实验组(培美曲塞脂质体)的细胞生存率显著小于对照组(等浓度梯度培美曲塞),P值分别为0.013、0.035和0.041。与空白组(等剂量PBS)比较,实验组(培美曲塞脂质体)和对照组(等剂量培美曲塞)Balb/c裸鼠肿瘤的体积和质量均显著减小;实验组肿瘤的体积和质量也均显著小于对照组(均P=0.000)。结论 ·相对于培美曲塞原料药物,脂质体能抑制MCF-7细胞的增殖,通过尾静脉给药能有效抑制肿瘤在Balb/c裸鼠体内的生长。
