BACKGROUND: The aim of the current study was to evaluate the anti-osteoarthritic and anti-inflammatory effect of naringin in a monosodium iodoacetate (MIA)- induced osteoarthritis (OA) model in rats. The anti-osteoarthritic potential of naringin was evaluated against the MIA-induced OA rat model.
MATERIAL AND METHODS: Wistar rats were used for the study and were divided into the following groups: normal control (saline-treated); group II (MIA-treated): group III (MIA+Naringin), and group IV (MIA+Indomethacin). The potential effect of naringin was evaluated via its effect on the level of proinflammatory cytokines, measuring the weight-bearing distribution, and histopathological analysis.
RESULTS: The anti-inflammatory effect of naringin was assessed in vitro in lipopolysaccharide-induced RAW 264.6 cells. The results suggest that naringin exerts an anti-inflammatory effect via reducing the production of the prostaglandin E2 (PGE2), nitric oxide (NO), interlukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) in LPS-induced RAW cells. Additionally, naringin also supported the recovery of hind-limb weight-bearing, reduced the generation or production of inflammatory mediator and proinflammatory cytokines, and protected the tissue from the damage in the OA model.
CONCLUSIONS: Naringin appears to be an effective therapeutic drug for the treatment of the OA and OA-related symptoms.
