Figure 6. Western blot analysis showing the effects of ICV microinjection of vehicle, LPS and (or) insulin on the ratio of phosphorylated P38 to total P38 protein in the hippocampi of rats. Representative immunoblots for phospho and total P38 are shown in the upper panel. **P < 0.01 represents the difference between control and the LPS receiving group (n = 4 for each group).
