Figure 10.

Effect of tolfenamic acid on reactive oxygen species production in PC12 cells cultured with 3-nitropropionic acid (3-NP). PC12 cells were treated with tolfenamic acid (5 and 10 μM) for 24 h and then with 3-NP (15 mM) for 8 h. DCF-DA (a) and DHE (b) were used as the fluorescent probe. All results are expressed as $\text{mean}\pm \text{S}\underset{¯}{\text{D}}$. n = 3; ^## p < 0.01 versus control; ^∗ p < 0.05 versus 3-NP. Magnification ×10.
