松针石油醚提取物抗肿瘤及诱导凋亡作用
摘要
目的:探讨松针石油醚提取物抗肿瘤作用机制。方法:建立荷S 180实体瘤小鼠模型
考察松针石油醚提取物体内抗肿瘤作用。应用免疫组化法检测肿瘤组织中凋亡相关蛋白Bax
Bcl-2的表达。结果:松针石油醚提取物0.5
1.0
2.0 g.(kg.d)-1 3个剂量组对S 180实体瘤的抑瘤率分别为31.16%
41.71%
42.16%。各用药组肿瘤组织Bax表达显著增强
Bcl-2表达显著降低。结论:松针石油醚提取物具有一定的抗肿瘤活性
诱导凋亡是其机制之一。
Abstract
Objective:To study the antitumor mechanism of petroleum ether extract of pine needles.Meth-od:Antitumor activity of the petroleum ether extract was determined by means of transplantable tumor(S 180) in mice.Immunohistochemical methods were employed for detection of Bax
Bcl-2 in tumor tissues.Result:The inhi-bition rate of peftroleum ether extract2.0 g.(kg.d)-1 on S 180-bearing mice was 42.16%.As for 1.0 g.(kg.d)-1 and 0.5 g.(kg.d)-1 groups
the inhibition rates were 41.71% and 31.16%.Expression of Bax in tumors was obviously increased and Bcl-2 was obviously decreased in all the therapy groups compared with the tumor control group(P < 0.01).Conclusion:Petroleum ether extract from pinee needles possesses definite antitumor effect.Ap-optosis is one of its antitumor mechanisms.
