  1. TNFα cytotoxicity was assayed with L929 cells as described in the legend of Figure 3. Oxidative glutamate toxicity (5 mM) and oligomycin (10 μg/ml)-induced cytotoxicity were determined with HT-22 cells after overnight treatment. aL-NAME: NG-monomethyl-L-arginine methyl ester.
  2. *: Significantly different from "No antioxidant or inhibitor" by ANOVA (P < 0.05).
