() was extracted using fermented ethanol. The effect of fermented ethanol extract of (FeCH) on chondrocyte viability was analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-iphenyltetrazolium bromide assay, which showed no cytotoxicity at 2 mg/mL. FeCH pretreatment in IL-1β-stimulated chondrocytes significantly inhibited the accumulation of nitric oxide and prostaglandin E, which was analyzed using the ELISA assay.

Inflammation and oxidative stress are crucial for osteoarthritis (OA) pathogenesis. Despite the potential of pharmacological pretreatment of chondrocytes in preventing OA, its efficacy in preventing the progression of cartilage damage and promoting its recovery has not been examined. In this study, an HO-induced human OA-like chondrocyte cell model was created using H1467 primary human chondrocytes to evaluate the efficacy of interleukin (IL)-6 and cyclooxygenase (COX)-2 inhibitors (tocilizumab and celecoxib, respectively) in the prevention and treatment of cartilage damage.

We studied the effect of acteoside on a model of human corneal epithelial cells (HCEC) injury induced by HO. HCEC were divided into 4 groups and cultured for 24 h in normal medium (intact and control groups, respectively), or in a medium containing DMSO or 160 μM acteoside (DMSO and acteoside groups, respectively). Then, HO solution was added to HCEC for 4 h, except for intact cells.
