Expression of OXA in LHA of the control and AMI group.

<p>A to C showing OXA-IR expressed in control group and D to F showing the AMI group, respectively; the positive cellular morphology indicated by arrows; the number and relative optical density (ROD) of OXA-IR neurons in AMI increased markedly as compared with those of the control rats(G); mRNA level of PPO in the hypothalamus in AMI group increased (H); values as mean±S.E.M (n = 7); * <i>P</i><0.05, **<i>P</i><0.01 when compared with the control group; scale bars = 50µm in A and D; 20µm in B and E; 10µm in C and F LH: lateral hypothalamic area; F: fornix.
