Prostaglandins biosynthesis and nitric oxide production have been implicated in the process of inflammation and osteoarthritis. And nitric oxide (NO) activated the MMPs responsible for PG degradation in articular chondrocytes. Therefore, we have studied the effects on anti-inflammation and analgesic by ethyl acetate fraction from 70% ethanol extract of Perilla Frutescens (EPF). EPF inhibited LPS plus inflammation-cytokines-induced proteoglycan (PG) degradation, matrix-metalloproteinase (MMP-2,9) expression in rabbit articular chondrocytes. Also, EPF have inhibitory effects on LPS or LPS plus inflammation cytokines-induced nitric oxide (NO) and PGE2 production in mouse macrophage andrabbit articular chondrocytes. These results suggest that EPF decreases PGE2, iNOS, MMPs activity and PG degradation in mouse macrophage and/or rabbit articular chondrocytes. In vivo, EPF was shown to have inhibitory effects on acetic acid-induced pain. The herbal extract with this profile, may have utility in the treatment of osteoarthritis.

In this study, extracts of Boswellia serrata gum resin, Curcuma longa rhizome, and Terminalia chebula fruit were combined in different ratios, and their anti-osteoarthritis effects were compared to determine which combination had the best synergistic effect. B. serrata, C. longa, and T. chebula extracts in a 2:1:2 ratio exhibited higher antioxidative activity in scavenging DPPH radicals than did the individual extracts alone or the other extract combinations. Additionally, the 2:1:2 combination significantly improved the levels of enzymatic antioxidants and antioxidant-related proteins. Moreover, this same combination ratio decreased the protein levels of matrix metalloproteinase (MMP) 3 and MMP13 in interleukin-1β-stimulated human articular chondrocytes (HCHs) and increased those of aggrecan and collagen type II alpha 1 chain (COL2A1). Analysis of the underlying mechanisms revealed that the 2:1:2 combination significantly inhibited the phosphorylation of nuclear factor kappa B (NF-κB) p65, extracellular regulated protein kinase (ERK), and p38 mitogen-activated protein kinase (MAPK). Therefore, the 2:1:2 combination of these three plant extracts has the best potential for use as an effective dietary supplement for improving joint health compared with the individual extracts and their other combination ratios.

Osteoarthritis (OA) is an inflammatory degenerative joint disease that is accompanied by irreversible joint cartilage destruction. Recently, the antioxidant effects of Carpomitra costata, which is a type of brown algae, have been reported, but their effects on OA have not been investigated. In this study, the anti-osteoarthritic effect of the ethanol extract of C. costata (EECC) on SW1353 human chondrocytes was studied. Results showed that EECC significantly attenuated the interleukin-1β (IL-1β)-induced release of pro-inflammatory mediators, including prostaglandin E2 and nitric oxide (NO), as well as expressions of cyclo-oxygenase-2 and inducible NO synthase. EECC also inhibited the IL-1β-induced expressions of matrix metalloproteinase-1, -3, and -13 in SW1353 chondrocytes, which reduced their extracellular secretion. In addition, the oxidative stress induced by IL-1β was confirmed to be blocked by EECC due to the inhibition of reactive oxygen species generation. Moreover, EECC suppressed IL-1β-mediated translocation of nuclear factor-kappa B (NF-κB) from cytosol into the nucleus and the degradation of IκB-α, which indicates that EECC exhibits anti-inflammatory effects by inhibiting the NF-κB signaling pathway. These results are the first to demonstrate the anti-inflammatory activities of C. costata extracts in chondrocytes, thus suggesting that this algae extract may be used in the treatment of OA.
