  • Glycyrrhizin (18$\beta$-glycyrrhetinic acid-3-O-$\beta$-D-glucuronopyranosyl-(1$\rightarrow2)-\beta$-D-glucuronide, GL) was transformed to 18$\beta$-glycyrrhetinic acid-3-O-$\beta$-D-glucuronide (GAMG) by Streptococcus LJ-22. The antiallergic activities of GL and GAMG was measured using a RBL cell assay system and contact hypersensitivity model mice. GAMG exhibited anti-allergic activity with $IC_{50}$ values of 0.28 mM. GAMG, which is sweeter than GL, and 18$\beta$-glycyrrhetinic acid, which is a GAMG metabolite by human intestinal bacteria, also inhibited the passive cutaneous anaphylaxis and skin contact inflammation. In conclusion, GAMG may be useful as a new sweet food additive and an anti-allergic agent.

  • The effects of Sagunjatang and Samultang on the immunosuppression induced by methotrexate(MTX) in rats were investigated in this study. The multiple parameters of immunity assessed in each rats included leukocyte count, lymphocyte rate, the number of lymphocyte in tibial bone marrow, contact hypersensitivity to DNFB, morphological change of thymocyte and IgG antibody on SDS-PAGE. Sprague-Dawley male rats were used and divided into five groups at random. Group A was normal control. Group B, the MTX treatment control, was injected i.v. with 2mg/kg of on days 9, 11 after sensitization with SRBC on 5th day. Group C, the experimental control, was treated Sagunjatang for 18days and MTX. Group D was treated Samultang for 18days and MTX. Group E was treated Sagunjatang-Samultang for 18days and MTX. The dosage of Sagunjatang and Samultang was $1m{\ell}/day$ respectively. In the case of Group E, rats Were fed Sagunjatang $1m{\ell}$ in the morning and Samultang $1m{\ell}$ in the afternoon. The results are summarized as follows: 1. Leukocyte count in rats induced by intravenous sensitization with SRBC was decreased significantly in Group E. 2. Leukocyte counts of 2weeks later after being treated MTX were increased significantly in Groups C and D. 3. Lymphocyte rate in rats induced by intravenous sensitization with SRBC wasn't changed significantly in all the experimental groups. 4. Lymphocyte rate of 2weeks. later after being treated MTX was increased significantly in Group D. 5. The number of lymphocyte in tibial bone marrow was incereased significantly in Group C. 6. Contact hypersensitivity wasn't changed significantly in all the experimental groups. 7. Morphological finding of thymocyte in group C was similar to normal group as compared with control group. 8. Purified IgG of all the experimental groups showed two bands of 50,000 and 25,000 on SDS-PAGE. But there was no difference among experimental groups.
