  • Title: Effects of shinbuto and ninjinto on prostaglandin E2 production in lipopolysaccharide-treated human gingival fibroblasts.
    Author: Ara T, Sogawa N.
    Journal: PeerJ; 2017; 5():e4120. PubMed ID: 29209578.
    Abstract:
    Previously, we revealed that several kampo medicines used for patients with excess and/or medium patterns (kakkonto (TJ-1), shosaikoto (TJ-9), hangeshashinto (TJ-14), and orento (TJ-120)) reduced prostaglandin (PG)E2 levels using LPS-treated human gingival fibroblasts (HGFs). Recently, we examined other kampo medicines used for patients with the deficiency pattern [bakumondoto (TJ-29), shinbuto (TJ-30), ninjinto (TJ-32), and hochuekkito (TJ-41)] and the herbs comprising shinbuto and ninjinto using the same experimental model. Shinbuto and ninjinto concentration-dependently reduced LPS-induced PGE2 production by HGFs, whereas hochuekkito weakly reduced and bakumondoto did not reduce PGE2 production. Shinbuto and ninjinto did not alter cyclooxygenase (COX) activity or the expression of molecules involved in the arachidonic acid cascade. Therefore, we next examined which herbs compromising shinbuto and ninjinto reduce LPS-induced PGE2 production. Among these herbs, shokyo (Zingiberis Rhizoma) and kankyo (Zingiberis Processum Rhizoma) strongly and concentration-dependently decreased LPS-induced PGE2 production. However, both shokyo and kankyo increased the expression of cytosolic phospholipase (cPL)A2 but did not affect annexin1 or COX-2 expression. These results suggest that shokyo and kankyo suppress cPLA2 activity. We demonstrated that kampo medicines suppress inflammatory responses in patients with the deficiency pattern, and in those with excess or medium patterns. Moreover, kampo medicines that contain shokyo or kankyo are considered to be effective for the treatment of inflammatory diseases.
