[Study on anti-tumor effect of medicinal fungi Phellinus igniarius extracts].

Objective: To study the inhibiting effect of medicinal fungi Phellinus igniarius extracts on S180 tumor and the immunoregulation effect on the S180-induced tumor mice.

Method: S180 mice were orally given 100, 200, 400 mg x kg(-1) dosage of P. igniarius extracts, then the inhibition grow effect, spleen index, and thyme index were measured.

Result: Medicinal fungi P. igniarius extracts can increase the spleen index and thyme index and the inhibiting tumor rate was 31.88%, 46.25%, 53.13%, respectively. Also, medicinal fungi P. igniarius extracts can prolong life in mice.

Conclusion: The medicinal fungi P. igniarius extracts show obviously anti-tumor effect and immunoregulation effect.
