OBJECTIVE: To explore the effect of proteins extraceed from mycelia of Omphalia lapidescens on inhibiting H22 liver cancer in vivo.
METHODS: 50 hepatoma 22 tumor bearing mice models were divided into five groups randomly:control group( CG), cyclophosphamide group, and 3 groups of incremental Hepatoma 22 dosages (5, 3, 1 mg/kg). All groups were i.v. with drugs once a day. After 8 consecutive days, the concentrations of interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) in serum were detected by enzyme-linked immunoabsorbent assay (ELISA). The weight changes of tumor, thymus, liver, heart, spleen, lung and kidney were observed.
RESULTS: It showed the tumors' weight were significant heavier in CG than in EGs. The tumor-inhibition rate (IR) was 36.4% in high dosage group,which was lower than 43.2% in cyclophosphamide group. The spleen mass of proteins groups increased significantly. The concentration of IFN-gamma in serum of proteins groups increased as CG, but IL-4 in inverse direction. The observations of thymus, liver, heart, lung and kidney in EGs were the same as CG.
CONCLUSION: The proteins extracted from mycelium of Omphalia lapidescens can inhibit the growth of tumour and enhance the immune function of H22 tumor-bearing mice.
