Objective : The genus Glycyrrhiza has been used in food and traditional herbal medicine. Glycyrrhiza new varieties Wongam and Sinwongam have been developed by Korea Rural Development Administration and investigated to register on Korean Pharmacopoeia of the Ministry of Food and Drug Safety. The aim of this study is to investigate the immunomodulatory effect of Wongam and Sinwongam comparing with listed Glycyrrhiza species (Glycyrrhiza uralensis Fischer and G. glabra Linne) for evaluations about pharmacological effect of Glycyrrhiza new varieties. Methods : We studied the immunomodulatory effect of Wongam and Sinwongam compared with G. uralensis and G. glabra using THP-1 cell in vitro model. The cells were treated with phorbol 12-myristate 13-acetate (PMA) for differentiation and stimulated with lipopolysaccharides (LPS) to induce immune activation. We analyzed and compared the effects Glycyrrhiza new varieties and listed Glycyrrhiza species using nitric oxide (NO) assay, western blot, and reverse transcription-quantitative polymerase chain reaction analysis. Results : Wongam and Sinwongam showed no cytotoxicity in THP-1 cells. Wongam and Sinwongam, and listed Glycyrrhiza species increased NO production, and cyclooxygenase (COX)-2 expression with or without LPS in differentiated THP-1 macrophages. Furthermore, Wongam and Sinwongam and listed Glycyrrhiza species upregulated the mRNA expressions of T helper type 1 (Th 1)-associated cytokines in LPS-stimulated THP-1 macrophages. Conclusion : These results indicated that Wongam and Sinwongam would have effect of enhancing immune response through the increase of NO and COX-2 expression, and activate Th1-associated cytokines. The findings of this study suggest the wide applicability of Glycyrrhiza new varieties.

Objective : The genus Glycyrrhiza has been used in food and traditional herbal medicine. Many experimental studies reported that Glycyrrhiza species possess several pharmacological properties. Glycyrrhiza new varieties WONGAM and SINWONGAM have been developed by Korea Rural Development Administration doing research for registration on Ministry of Food and Drug Safety. During the evaluations about pharmacological effect of Glycyrrhiza new varieties WONGAM and SINWONGAM, we focused the anti-allergic effect in this study. Methods : We investigated the anti-allergic effect of WONGAM and SINWONGAM compared with Glycyrrhiza uralensis Fischer and G. glabra L. using anti-dinitrophenyl-immunoglobulin E (IgE)/human serum albumin-stimulated RBL- 2H3 cells, phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 cells and compound 48/80-induced anaphylaxis mice model. We analyzed the effect on the expression of various cytokines, and IgE from mast cells and the underlying molecular mechanisms of WONGAM and SINWONGAM in presented models. Results : WONGAM and SINWONGAM showed the inhibitory effect on the histamine release from rat peritoneal mast cells or human mast cells without cytotoxicity. WONGAM and SINWONGAM blocked anaphylactic shock and decreased the IgE production. Furthermore, WONGAM and SINWONGAM inhibited the productions of TNF-α and IL-6 in compound 48/80-induced anaphylaxis mice model. Conclusion : These results indicated that WONGAM and SINWONGAM would have protect effect on allergic responses through the inhibition of allergic mediators and pro-inflammatory cytokines. This study may facilitate the development on Glycyrrhiza new varieties for allergy.

Objectives : The Glycyrrhiza new varieties, WONGAM and SINWONGAM, were developed through interspecific cross between Glycyrrhiza glabra and Glycyrrhiza uralensis by the National Institute of Horticultural and Herbal Science, Rural Development Administration in Korea. This in vitro study was undertaken to compare the antioxidant and cytotoxic effects between Glycyrrhiza new varieties (WONGAM and SINWONGAM) and official compendia (Glycyrrhiza glabra and Glycyrrhiza uralensis ). Methods : Antioxidant activity was determined by DPPH (1,1-diphenyl-2-picrylhy drazyl), ABTS (2,2-azino-bis (3-rthylbenz-thiazoline-6-sulfonic acid)) diammonium salt, Nitrite radical scavenging assay, and Reducing Power assay. Cytotoxicity was determined by MTT assay and cell morphology was observed by an inverted microscope. Results : The DPPH, ABTS, Nitrite radical scavenging activities and reducing power of Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM were evaluated at different concentrations (0, 10, 50, 100, 500, 1000 ㎍/㎖). Glycyrrhiza glabra , Glycyrrhiza uralensis , WONGAM, and SINWONGAM showed similar dose-dependent increase in antioxidant activities. The cytotoxic effects with increasing doses of Glycyrrhiza new varieties and official compendia did not differ in HCT116, HT29, A549, MDA-MB231, PC3, ACHN, and HeLa cells. However, significant difference in cytotoxicity were observed in AGS, MCF7 and Hep3B cells by Glycyrrhiza glabra , Glycyrrhiza uralensis , WONGAM, and SINWONGAM. Conclusions : These results showed that Glycyrrhiza new varieties and official compendia acts as a potent antioxidant. Also, the finding that equivalent cytotoxic potency was observed in a cell dependent manner. Our study suggests that Glycyrrhiza new varieties may offer a wide-variety of health benefits.
