[Experimental study on xiaoliu decoction in treating tumor and modulating immune function].

OBJECTIVE

To study the anti-tumor effect and immune function modulation of Xiaoliu decoction (XLD) and to explore the possible mechanism.

METHODS

S180 tumor bearing mice were treated with large or small dose of XLD and cyclophosphamide (CTX) to observe the tumor suppressive rate, lymphocyte transformation rate, natural killer cell (NK) activity, tumor necrosis factor alpha (TNFalpha) level in the mice, as well as the tumor cell apoptosis in vitro.

RESULTS

The tumor suppressive rate of XLD on tumor bearing mice was over 30%. XLD showed obvious trend in enhancing the tumor suppressing rate of chemotherapy, could increase the lymphocyte transformation rate, NK activity, and TNFalpha level. It also could accelerate the tumor cell apoptosis in vitro.

CONCLUSION

XLD has significant anti-tumor effect, it could elevate the immune function or organism and alleviate the chemotherapy induced lowering of immune function.
