【Abstract】 The polysaccharieds from Auricularia auricula Underw. Tremella fuciformis Berk. and Tremella fuciformis Berk, spores were found to stimulate the human lymphocyte proliferation by using both ~3H-TdR and ~3H-UR incorporation. Aftar the whole blood was cultured for 72 hours, the incorporation rate of ~3H-TdR into DNA was significantly increased by 1.20, 0.79 and 0.75 times respectively, the incorporation rate of ~3H-UR into RNA was also significantly increased by 1.52, 1. 11 and 1.20 times respectively compared with the control.更多还原
