[Effects of Feiji Formula on lung cancer metastasis in mice].

OBJECTIVE

To observe the effects of Feiji Formula, a compound traditional Chinese herbal medicine, on lung cancer metastasis in mice.

METHODS

The lung cancer metastasis model of mice was established in this experiment study. Twenty-four mice were randomly divided into three groups: untreated group, cisplatin group and Feiji Formula group. Mice in the Feiji Formula group were treated with Feiji Formula decoction; in cisplatin group, with cisplatin by intraperitoneal injection; and in the untreated group, with normal saline (NS). After twenty-day treatment, the body and tumor weights as well as the number of metastatic tumors in both lungs of each mouse were measured.

RESULTS

The body weight of mice in cisplatin group was significantly less than that of Feiji Formula group and untreated group (P<0.01); the tumor weight of mice in cisplatin group and Feiji Formula group was markedly lower than that of untreated group (P<0.01); and the number of metastatic tumors in cisplatin group and Feiji Formula group was markedly lower than that of the untreated group (P<0.01), no significant difference between the Feiji Formula group and cisplatin group in terms of the weights and the numbers of metastatic tumors in bilateral lungs.

CONCLUSION

Feiji Formula can suppress tumor growth and decrease the number of lung metastatic tumors in the mice, and maintain the body weight of the mice.
