Protective effects of Rhizoma smilacis glabrae extracts on potassium oxonate- and monosodium urate-induced hyperuricemia and gout in mice
Copyright © 2018. Published by Elsevier GmbH..
BACKGROUND: Rhizoma smilacis glabrae (RSG, tufuling) has been widely used in traditional Chinese medicine for deoxidation, dampness relief, and easing joint movement. The chemical composition of RSG has been systematically confirmed, and some of its compounds have been revealed to possess antioxidant, anti-inflammatory, immunomodulatory, hypouricemic, and hepatoprotective effects.
PURPOSE: We aimed to clarify whether a RSG extract attenuates hyperuricemia, paw edema, and renal injury in mice with potassium oxonate (PO)- and monosodium urate (MSU)-induced chronic hyperuricemia and gout.
METHODS: RSG water extract was obtained and analyzed by HPLC-DAD-MS/MS. To establish a murine model with chronic hyperuricemia and gout, PO was orally administered daily from day 0 to day 24, whereas MSU was injected into the tibiotarsal joint on day 21. The mice in the drug intervention groups were treated once daily with doses of allopurinol or RSG extract from day 21 to day 24. The diameter of the ankle joints was measured with calipers. Serum TNF-α and IL-1β concentrations, hepatic XOD activity, and uric acid, creatinine, and blood urea nitrogen (BUN) levels were also determined. The right kidney and articular cavities were fixed, cut into sections, and stained with hematoxylin and eosin.
RESULTS: Nine compounds in the RSG water extract were unambiguously identified as 5-O-caffeoylshikimic acid, neoastilbin, astilbin, taxifolin, neoisoastilbin, isoastilbin, engeletin, isoengeletin, and trans-resveratrol. The RSGE treatment dose-dependently reduced PO- and MSU-induced paw edema, serum TNF-α, IL-1β, IL-6, IL-12, uric acid, and BUN, while significantly elevated serum IL-10, urinary uric acid and creatinine levels as compared with the respective values in the hyperuricemic and gouty mice group (vehicle group). Moreover, the hepatic XOD activity was dose-dependently reduced by the RSGE treatment. In addition, RSGE treatment not only ameliorated the infiltration of inflammatory cells, tubular dilation and vacuole formation in renal tubular, but also improved the synovial hyperplasia, reduced inflammatory cells infiltration into the synovium, and diminished the erosive damage in the cartilage.
CONCLUSION: The murine model with chronic hyperuricemia and gout be built in present study is consistent with the clinical symptoms of patients with long-standing hyperuricemia and acute gouty arthritis. RSG water extract has potent efficacy in ameliorating murine hyperuricemia and gout induced by PO and MSU.
