Another important yet little-appreciated cause of anticancer drug resistance is the limited ability of drugs to penetrate tumor tissue and to reach all of the tumor cells in a potentially lethal concentration. To reach all viable cells in the tumor, anticancer drugs must be delivered efficiently through the tumor vasculature, cross the vessel wall, and traverse the tumor tissue.

Methods: Mice bearing in vivo transplanted tumor-H22 hepatic carcinoma were used to evaluate the drug"s activity of anti-tumor and GAPSGF"s efficacy enhancing effect by calculating the ratio of antitumor and q. HE dyeing was applied to observe the tumor"s morphological changes after the anti - tumor drug. It is observed the change of theperipheral white blood cells in serum and the body weight to analyze the GAPSGF"s toxicity reducing effect on the anti - tumor drug-Cytoxan. Applying ELISA method to observe the change of IL-2 in serum ,Applying carbon clearance method to test the function of uninuclear phagocyte,took the weight of the spleen and thoracic gland, analyzed the mechanism — efficacy enhancing and toxicity reducing of GAPSGF.

Based on these previous work, in this research, in order to explore the the molecular mechanism of enhanced tumor cell immunogenicity treated by elemene and mytomycin C compositely, we used murine Hca-F ascitic hepatic carcinoma ( high lymphatic metastasis substrain of H22) as an experimental model to compare the immunoprotective effects on Hca-F cells as well as the mechanism of the effects caused by HSP70-peptide complex purified from untreated tumor cells, EC-TCV and BCG; We studied the mechanism of increased tumor cell membrane HSP expression treated with elemene by the techniques of RT-PCR and immunoelectron microscopy; In order to deeply elucidate the antitumor effects and the molecular mechanism of elemene in increasing tumor cell immunogenicity we analyzed and compared the effects of elemene and heat shock on the gene expressions of tumor cell using gene expression profile chip.
