Figure 3. Effects of echinochrome (10, 1, and 0.1 mg/kg) on tumor necrosis factor-α (TNF-α) in aqueous humor collected 24 h after lipopolysaccharide treatment are shown. Data are presented as mean ± standard error of the mean (SEM; n=4). ** TNF-α concentration is significantly lower in echinochrome (10 and 1 mg/kg) treated groups than untreated endotoxin-induced uveitis (EIU) rats (p<0.01).
