Expression of TNFα mRNA and IL-6 mRNA in the LPS-treated rats. A, Relative expression of TNFα and IL-6 mRNA. LPS treatment induced upregulation of TNFα and IL-6 mRNA levels, increasing the expression of both mRNAs by 24-fold at 1 hour following LPS-treatment, and IL-6 expression rose by 68-fold at 3 hours post-treatment. B, Agarose gel electrophoresis imprinting for TNFα and IL-6 mRNA at 1 hour after LPS administration. **P < 0.001, relative to the TNFα control group; ##
P < 0.001, relative to the IL-6 control group.
