(46) As shown in Table 3, each of the groups of examples 1 to 8 decreased the expression rate of VEGF and TGF-β 1 positive cells in mice tumor. Therein, the differences of VEGF and TGF-β 1 positive cells between examples 5 to 8 and the model groups were statistically significant (P<0.05), while the differences between examples 1 to 4 and the model group were not significant. Detection values of both the VEGF and TGF-β 1 positive cells of the group of Example 5 were the least, (58.53±5.91)% and (6.25±.sup.30.31)%, respectively. The second least was Example 8, (59.31±3.21)% and (60.96±1.51)%, respectively. The results indicated that both the individual components and the traditional Chinese medicine compositions decreased the expression rate of VEGF and TGF-β 1 positive cells in mice tumor, inhibited the expression of immune inhibitive factors in local tumor tissue, therefore delaying the development of tumor and improving the immune status of body. They could be used in preparing health products and foods, for preventing and assisting in treating tumor. However, the effects of the traditional Chinese medicine compositions were better than that of the individual components.

(47) It can be concluded from the above results that the traditional Chinese medicine compositions comprising Lycii fructus polysaccharide, Polygonati rhizoma polysaccharide, Caryophylli flos oil and Cinnamomi cortex oil can inhibit the growth of tumors, improve percentages of CD4.sup.+ and CD8.sup.+ cells in the lymphocytes of the tumor stroma, and decrease the expression rate of VEGF and TGF-β 1 positive cells in mice tumor.
