glomerata compound had anti-fatigue effect.The immunocompromised model of mice was used to verify its promoting effect on immunity.Compared with the model group,the Pfaffia glomerata compound and the positive control group increased the Ig G,Ig M and Ig A immunoglobulins of mice(P>0.05).The Con A-induced lymphocyte transformation rate and NK cell activity in mice were significantly increased in the middle and high dose groups of Pfaffia glomerata compound and the positive control group(P<0.05).Normal mice were used to verify the immunoregulatory effect.Compared with the blank group,the DTH and HC50of mice in the medium-and high-dose groups of Pfaffia glomerata compound and the positive control group were significantly increased(P<0.05)Pfaffia glomerata compound increased the number of
