Abstract

Postischemic lesion following reperfusion have been investigated in the gerbil by temporary occlusion of a common carotid artery. Two phenomena have been reported in injured ischemic cells: the inability to restore mitochondrial function and evidence of plasma membrane damage. For Further understanding the pathophysiological mechanism of ischemic lesion, we have evaluated the various ischemic period and early postischemic reperfusion. in addition to the morphological changes of the dentate gyrus by light microscopy, we employed the immunocytochemical staining for iNOS and eNOS.

The mongolian gerbil, Meriones unguiculatus, were anesthetized with α-chloralose (350mg/kg), bilateral common carotid artery occlusion was induced for 90 minutes. The right common carotid artery was ligated with 5-0 silk suture, and the left was clamped by a micro vascular/miniature aneurysmal clip. After an ischemic period of 90 minutes, restoration of the blood flow of the left common carotid artery was accomplished by withdrawing the microvascular clip.
