[Rhodiola sachalinensis suppresses T241 fibrosarcoma tumor cells proliferation in vitro and growth in vivo].

OBJECTIVE

To study the anticancer activity of Rhodiola sachalinensis in vitro and in vivo experiments.

METHODS

The effect of Rhodiola sachalinensis extracts at various concentrations on T241 fibrosarcoma cells proliferation and cytotoxic potential were measured. We divided T241 fibrosarcoma-bearing C57Bl6/J mice into two groups, the tumor inhibition rate were observed.

RESULTS

Rhodiola sachalinensis extracts inhibited T241 tumor cells growth in a dose-dependent manner. The concentrations of Rhodiola sachalinensis extracts from 50 microg/ml to 250 microg/ml did not reduced the survival rate of T241 tumor cells. The daily administration of Rhodiola sachalinensis resulted in a significant suppression of the growth of primary tumors, compared to control group, tumor inhibition rate in Rhodiola sachalinensis group reached 70.9%.

CONCLUSION

Rhodiola sachalinensis can inhibit T241 tumor cells growth and does not cause a direct cytotoxicity against tumor cells in vitro and in vivo.
