Abstract:
Objective:To observe the effect of prolonging life and inhibiting tumor growth of Xiaozhensan on H22 cells-bearing mice and study the mechanism of action. Methods:①H22 cells-bearing mice models were made by subcutaneous injection and were divided into six groups:model group,low,middle and high dosage groups of Xiaozhensan,5-FU group,5-FU plus Xiaozhensan middle dosage group. After 10 days' treatment,the mice were killed and the anti-tumor rates were calculated,to detect the content of IL-2 and observe pathological sections of tumor and expression of Bcl-2 by immunohistochemical method. ②H22 cells-bearing ascites mice models were divided as the above. The living days of the mice were recorded,the prolongation of life span were calculated. Results:Xiaozhensan had the function of inhibiting the growth of tumor,and there was the dependability between quantity and effect. In pathomorphology,the sections of Xiaozhensan groups showed nuclear shrinkage,necrosis,hemorrhage,inflammatory cell infiltration on the periphery,etc. Xiaozhensan could increase the content of IL-2 and inhibit the expression of Bcl-2. Xiaozhensan combined with 5-FU can prolong the life span of the mice bearing ascites tumor. Conclusion:Xiaozhensan had the function of inhibiting the growth of tumor. The mechanism of action may be concerned with these aspects:enhancing the cellullar immunologic response and strengthening the ability to resist tumor,inducing apoptosis and weakening reproductive activity of tumor,etc. Middle dosage group of Xiao Zhen San combined with anticarcinogenic western medicin can prolong the life span of the mice bearing ascites tumor. This study provided dependable experimental documents for clinical application of Xiaozhensan,and had some guiding significance in clinic.
