TH immunohistochemical staining of the infarct border zone (DAB color, ×200). (a) Sham-operated group. The distribution of TH-positive nerve fibers is orderly. (b) Control ischemic group. TH-positive nerve fibers in ventricular muscle increased significantly it is thickened and disorderly. (c) Preischemic treatment group. (d) Delayed application group. The distribution of nerve fibers after treatment with desipramine significantly improved. The change of preischemic treatment group was more obvious.
