Effects of ouabain (OUA) pretreatment (1.8 μg/ kg) on lipopolysaccharide (LPS)-induced (200 μg/ kg) serum corticosterone and TNF- α. (A) The serum levels of corticosterone were elevated in LPS and OUA + LPS in comparison with control and OUA group, ^a P < 0.01 versus control and OUA and ^b P < 0.01 versus control and OUA. (B) The same pattern occurs in TNF-α serum levels, ^a P < 0.05 versus control and OUA and ^b P < 0.05 versus control and OUA. Data are presented as mean ± SEM from five individual experiments. One-way ANOVA followed by Newman-Keuls post-test.
