A PRELIMINARY STUDY ON IMMUNE REGULATION OF AMMONIUN GLYCYRRHIZANATE / 中国药理学通报

After mice given Ammoniun Glycyrrhizanate orally, the spleen weight, the number of leukocytes in peripheral circulation and carbon particle cleaning index increased significantly. Rat spleen lymphocytes exposed to 8 x10-7M and 8 x10-10M of Ammoniun Glycyrrhizanate produced levels of PGE that were 1 - 2 -fold greater than that of the control lymphocytes cultured in medium alone. We also found that the levels of PGE2 and cAMP in mice spleen increased significantly after P.O. Ammoninn Glycyrrhizanate, which we suggested might be the mechanisms of immane regulatory functions of Ammoniun Glycyr rhizanate.
