Objective To extract,isolate and identify the polysaccharide from ginseng,and to investigate its anti-tumor activity in vitro. Methods The ginseng polysaccharide was obtained through water extraction and ethyl alcohol deposition method. Use the Sevage method to remove the protein in the crude polysaccharide. The structural characteristics of the polysaccharide were determined by FT-IR spectra.The RM-1 and HeLa cells were divided into control group and different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )of ginseng polysaccharide groups. The survival rates of the cells in various groups were detected by MTT method. The indirect killing effects of ginseng polysaccharide with different concentrations (0,50,100,200,300,400 and 500 mg·L-1 )on the cancer cells were determined by CTL test. Results The extraction rate of ginseng polysaccharide was 8.7 6% and the structural characteristics demonstrated that the main component of the extract was polysaccharide.The result of MTT showed that there were no significant differences of the survival rates of RM-1 and HeLa cells between different concentrations of ginseng polysaccharide groups after treated for 24 h compared with control group (P>0.05).The result of CTL test showed that the cytototic LHD release rates in different concentrations of ginseng polysaccharide groups were increased significantly (P<0.05)compared with control group;with the increase of ginseng polysaccharide concentration, the cytotoxic LDH release rates were increased firstly and then were decreased.When the concentration of ginseng polysaccharide was 100 mg·L-1 ,the cytotoxic LDH release rate was the biggest.Conclusion Ginseng polysaccharide can indirectly inhibit the growth of the tumor cells by activating T cells and play an anti-tumor effect.

Orthogonal experiment was used to study mixing methods. Cytotoxic T lymphocyte experiment and LDH release assay were performed to detect the influence of polysaccharide complex of GPS,PTM,and PLE in the CTL killing activity,and its indirect killing effect on the P815 cells.Results The extraction rates of GPS,PTM, and PLE were 8.85%,9.40%,and 10.50%;the levels of total polysaccharides were 62.96%,59.13%,and 33.86%;the levels of uronic acid were 16.44%,9.37%,and 16.44%;the starch levels were 7.26%,2.80%,and 3.77%,respectively.The identification results showed that the polysaccharides were obstrained.When the quality ratio of the three kinds of polysaccharides was 1∶1∶1 and the concentration was 600 mg·L-1 ,the CTL cytotoxicity was the highest.Conclusion The polysaccharide complex is obtained,identified and characterized. Polysaccharide complex can enhance the cytotoxicity of CTL and has the indirectly inhibitory effect on the proliferation of P815 cells.

Objective:To determine the inhibitory effect of Rupixiao ( RPX) granule on mammary gland hyperplasia ( HMG) in rabbits and explore the possible mechanism to provide reference for clinical medication. Methods:Rabbit model of mammary hyperpla-sia was established by estradiol benzoate and progesterone. Xiaoyao pills and tamoxifen were used as the positive control, and the RPX granule group was respectively at low, medium and high dose (0. 525,1. 05,2. 1 g·kg-1). Each group was with intragastric adminis-tration for 30 days. The levels of E2 , PROG, FSH, LH and PRL in serum and the expression of VEGF in the homogenate tissue were determined by an Elisa method. The breast tissue of rabbits in each group was withdrawn to observe the structure changes after Hema-toxylin-eosin staining ( HE) . Results:Ovarian preservation-benzoic acid, estradiol combined with progesterone could be used to estab-lish mammary gland hyperplasia in rabbits. RPX granule could significantly decrease the serum levels of E2 and PRL (P<0. 01)and increase that of PROG (P<0. 01 or P<0. 001). The results of pathological section showed that the breast structure in RPX granule high dose group could be restored to the level of the blank control group, which showed its therapeutic effect on HMG was better than that of tamoxifen and Xiaoyao pills. The expression of VEGF in each treatment group significantly decreased compared with that in the model group by the Elisa reagent (P<0. 001). Conclusion:RPX granule has good efficacy in HMG rabbits. The inhibitory effects of RPX granule on HMG in rabbits maybe related to the inhibition of VEGF in rabbit breast tissues, and the inhibition of RPX granule was similar to that of tamoxifen and Xiaoyao pills.
