Fig. 1From: Spinacia oleracea extract attenuates disease progression and sub-chondral bone changes in monosodium iodoacetate-induced osteoarthritis in ratsSOE has antioxidant activity and is non-toxic for chondrocytes. a MTT assay at different concentrations of SOE (μg/ml) showed that it is safe and does not impart toxic effects on chondrocyte viability. b Anti-oxidant ability of SOE by DPPH and (c) lipid peroxidation inhibition by MDA assay (D) Free radicals scavenging activity by ABTS assays and (E) GAG release measurement by DMMB assays. All values are expressed as mean ± S.E.M. (n = 6); *P < 0.05; **P < 0.01, ***P < 0.001 compared to controlBack to article page
