1, promoting human immunity:
Tremella polysaccharide can increase spleen index, half hemolysis value (HC50) and rosette formation rate of mice, and promote phagocytosis of macrophages and lymphocyte transformation. 250mg/kg tremella fuciformis mycelium, injected intraperitoneally in mice for 7 days, can significantly increase the percentage of peripheral blood T lymphocytes; Subcutaneous injections of 400mg/kg and 800 mg/kg * * for 7 days restored the half hemolysis value HC50 caused by cyclophosphamide to normal.
2. Promote the biosynthesis of nucleic acid and protein;
Tremella polysaccharide 100μg can significantly promote the synthesis of deoxyribonucleic acid and ribonucleic acid by human lymphocytes. Intraperitoneal injection of tremella polysaccharide (100 mg/kg) in mice for 4 days had a weak promotion effect on the incorporation of 3H leucine into serum protein of mice.
3, hypoglycemic effect:
When 8.25mg/kg tremella polysaccharide was injected into mice, the anti-implantation and anti-early pregnancy effects were the most obvious, and the effect of terminating the second trimester pregnancy was slightly worse, but it was ineffective for transporting pregnant eggs.
4, anti-cancer, anti-mutation effect:
The hot water extract of tremella fuciformis has an inhibitory rate of 42.5% ~ 70% on sarcoma S 180 in Swiss mice and 80% on Ehrlich ascites carcinoma. Tremella polysaccharide 200 mg/(kg d) for 65438±00d days can prevent the increase of micronucleus rate in bone marrow of mice caused by cyclophosphamide.
5, antithrombotic formation:
Oral administration of tremella polysaccharide 18.5mg/kg to rabbits can obviously prolong the formation time of specific thrombus and fibrin thrombus, shorten the length of thrombus, reduce the wet and dry weight of thrombus, reduce the number of platelets, and reduce the platelet adhesion rate and blood viscosity.
It can obviously shorten the euglobulin lysis time of guinea pigs, reduce the content of plasma fibrinogen and increase the activity of fibrinolytic enzyme. The results show that tremella polysaccharide has obvious antithrombotic effect.
