[Effect of Epimedii Herba alcohol extract on inhibition of lung tumor growth and immunomodulatory].

ABSTRACT

To observe the effect of Epimedii Herba alcohol extract (HE) on tumor growth of lung cancer by establishing the model of Lewis tumor-bearing mice, ELISA method was used to detect the levels of TNF-α, IL-10, IL-17, IL-2 in serum. Ki67 and P53 protein expression was detected in lung cancer tissues by using Western blot assay method and immunohistochemical assay method. The experimental results showed that HE has certain inhibitory effect on Lewis lung cancer tumor growth, and it can reduce the levels of TNF-α, IL-10 and IL-17 in serum, improve the level of IL-2,significantly decrease the expression of Ki67, and significantly increase P53 expression. HE has obvious inhibitory effect against lung cancer, and has the ability to improve immune regulating effect. This study reveals the anti-lung cancer effect of HE may be related to its ability of improving immunity, thus provides the basis for further research on anti-lung cancer effect of HE.
