摘要
目的:比较鬼臼毒素纳米脂质体和鬼臼毒素混悬液抗肿瘤作用。方法:以每只0.2 mL肿瘤细胞悬液,接种于小鼠右前肢腋部皮下,24 h后将小鼠随机分组,各组分别给不同浓度的鬼臼毒素纳米脂质体、鬼臼毒素混悬液、环磷酰胺(CX)、生理盐水。环磷酰胺1次性腹腔注射,其他组每4天腹腔注射1次,共3次,停药后第12天将小鼠拉颈处死,剥取瘤块称重,计算抑瘤率。结果:鬼臼毒素纳米脂质体和鬼臼毒素混悬液在5.0 mg.kg-1剂量时对小鼠肝癌H22瘤体生长有抑制作用,抑瘤率分别为52.37%和38.25%。结论:鬼臼毒素纳米脂质体和鬼臼毒素混悬液有抗肝癌作用,且相同剂量下,鬼臼毒素纳米脂质体比鬼臼毒素混悬液抑瘤效果显著。
Objective： To compare the antitumor effects of the podophyllotoxin nanoliposome and the suspensions of podophyllotoxin in bearing-tumor mice. Method： The experimental mice were inoculated by suspension liquid of tumor cell in axillary region near the forelimb, 0.2 mL each. The mice had been randomly divided into 8 groups 24 h latter. The podophyllotoxin nanoliposome, suspension liquid of the podophyUotoxin, C,X or NS was given to each group respectively. Except CX was given by celiac injection once, the other groups were injected every 4 days for three times. The mice were killed by hauling necks on the twelfth day after treatment, the tumor was weighed and the inhibitory rate was calculated. Result： When the dosage of podophyllotoxin nanoliposome and the suspensions of podophyllotoxin reached 5.0 mg· kg^-1, the rate of inhibiting tumor were 52.37 % and 38.25 % to the H22 liver cancer of mice respectively. Conclusion： podophyllotoxin nanoliposome and the suspensions of podophyllotoxin have the effect in anti-liver cancer. And podophyllotoxin nanoliposome have stronger inhibitory rate compared with suspension liquid of the podophyllotoxin in same dose.
