[Anti-tumor effect of polysaccharide from Grifola frondosa and its influence on immunological function].
Zhong Yao Cai. 2003 Jan;26(1):31-2. PMID: 12858772
When the polysaccharide from Grifola frondosa (PGF) was taken orally by S180 bearing mice at the dosage of 50-150 mg/kg.d for 9 d, the inhibitory rate to S180 was 27.97%-38.46%. The PGF can also enhance thymus index, the ability of splenic lymphocyte proliferation and formation of antibody in splenic cells, and promote the production of IgM hemolysin significantly in S-180 bearing mice.
