The different levels of
Tremella aurantia were given to Kunming male mice for 20 days,ig,continuously, and the control
group was fed distilled water.The results showed that:①All different levels of
Tremella aurantia (high level:200 ml/kg, medium level:100 ml/kg, low level:20 ml/kg)could increase the phagocytosis of macrophages against cock erythrocytes in mouse abdominal cavity and dose-respones relationship was observed in all levels.There was significant difference between high,medium and control groups ( P<0 01,P<0 05 ),but no difference in phagocytic index( P>0 05 ).②Dose-effect was observed in the effect of Tremella aurantia on delayed allergic reaction (footpael reaction)and hemolysin test.However,all levels showed no significant difference compared with control group.③The high and medium levels of HC 50 showed significant difference compared with control group( P <0.05).④The high level could profoundly raise spleen(lien)index,and showed statistical difference with control group( P <0.05).In thymus index, there was no difference in two level groups compared with control group. In coclusion, Tremlla aurantia shows somewhat adjusting effects on specific
immunnocompetence of mice,and the high and medium levels have beneficial effect for increasing mice'nonspecific immunnocompetence.
