ABSTRACT

[Objective]To study the inhibitory effect of the extract of Rhizoma Amorphophallus,we set up the Kunming mices which were vaccinated with H22 tumor as experimental model,and explore the possibility mechanism of them.[Method]We adopted the mices vaccinated with H22 tumor as experimental model to observe the influence of different extracts on the antitumor ratio,and the cooperating antitumor effect together with 5-Fu.Using flow cytometry to detect the effect of petroleum ether extract on apoptotic cells.Using immunohistochemical method to observe the influence of this extract to the expression of Survivin and Bax(Bcl-2 associated protein x).[Result]The extract of petroleum ether of Rhizoma Amorphophalli had inhibitory effect of the growth on mice vaccinated with H22 tumor,and the possible mechanism was the downregulation of Survivin expression and upregulation of Bax expression to induce apoptosis of tumor cell.
