(b, c) The cytotoxic effects of curcumin and TBHP on rat chondrocytes were examined at various concentrations for 24, 48, and 72 hours with a CCK8 kit. ^∗∗ P < 0.01, ^∗ P < 0.05 versus the control group. (d) The viability of TBHP-treated (20 μM) chondrocytes after curcumin treatment. ^## P < 0.01 versus the control group; ^∗∗ P < 0.01, ^∗ P < 0.05 versus the TBHP treatment group.
