摘要
目的探讨蟾酥脂质体注射液(CS)的抗肿瘤作用。方法体内实验采用小鼠肝癌H22、肉瘤S180荷瘤小鼠模型,考察CS的抑瘤作用;采用小鼠接种肝癌H22后,用环磷酰胺造成免疫低下模型,考察CS提高机体免疫力作用。体外实验采用MTT法,测CS对人宫颈癌HeLa细胞或人肝癌BEL-7402细胞增殖抑制率。结果CS(0.2、0.4、0.8mg·kg^-1)对2种荷瘤小鼠肿瘤增长有显著或非常显著的抑制作用(P〈0.05,P〈0.01);同时对机体具有明显的免疫调节作用。CS0.01-3.00mg·L^-1对人宫颈癌HeLa细胞或肝癌BEL-7402细胞增殖有非常显著的抑制作用;CS对人宫颈癌Heh细胞Ic50为0.51mg·L^-1,95%可信限0.2132-1.2140mg·L^-1,CS对人肝癌BEL-7402细胞ICsn为0.75mg·L^-1,95%可信限0.3126-1.8015mg·L^-1。结论蟾酥脂质体注射液体内、体外均有抗肿瘤活性,且具有免疫调节功能。
Objective To observe antitumor effect of Venenum Bufonis liposome injection(CS). Methods In vivo, the models of hepatocarcinoma 22 (H22) , sarcoma 180 (S180) in mice and immune function inhibited mice induced by Cytoxan were establisehd. In vitro, time and dose effects of CS in HeLa cell and BEL-7402 human hepatocarcinoma cell lines were detected using MTT assay. Results The studies demonstrated that CS(0.2, 0.4, 0.8 mg·kg^-1 ) had obvious antitumor effects on H22 and S180 ( P〈0.05, P 〈 0.01 ), and had activities of immunoregulation; CS(0.01 - 3.00 mg· L^-1 ) could inhibit proliferation of HeLa cells( IC50: 0.51 mg·L^- 1, 95% confidence interval: 0.2132 - 1.2140 mg·L^- 1 ) and BEL-7402 cells( IC50: 0.75 mg·L^-1,95 % confidence interval :0.3126 - 1.8015 mg·L^-1). Conclusions CS has antitumor effects both in vlvo and in vitro. It also shows immunoregulation activities.
