objective to compare the anti-aging effects of lycium barbarum polysaccharides and tanshinone on the skin of d-galactose-induced mice aging model.methods 60 female mice were randomly divided into 4 groups (n=15):mice in normal control group received subcutaneous injection of normal saline and mice in the other 3 groups received cervicodorsal injection of d-galactose［1000 mg/(kg1·d)］ for 42 d to establish subacute aging model.the experimental groups included agingmodel group,lycium barbarum polysaccharides ［200 mg／group,tanshinone ［1 500 mg／］ group.forty two days later,the dorsal skin samples were collected to determine sod activities、mda and hydroxyproline contents.

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.
