The aim in this study was to investigate whether our experimental model for stroke therapy, flushing the ischemic territory with saline prior to reperfusion, could ameliorate disruption of microvascular integrity by reducing matrix metalloproteinase (MMP) expression during reperfusion. Stroke in Sprague Dawley rats (n = 42) was induced by a 2-h right middle cerebral artery (MCA) occlusion using a novel intraluminal hollow filament. Prior to reperfusion, 24 of the ischemic rats received 6ml isotonic saline at 37 degrees C infused into the ischemic area through the filament. Brain edema was determined by comparing the percentage difference in brain volume between the right and left (contralateral to stroke site) hemispheres, while the expressions of MMP-2 and -9 mRNA were analyzed by real-time reverse transcriptase-polymerase chain reaction (real-time RT-PCR). A significant (p < 0.01) brain edema, determined by an increased brain volume of 19 +/- 4%, and overexpression of the mRNA encoding MMPs, determined by increased relative mRNA level ratio, were found in ischemic rats. The brain damage, in terms of brain edema (4 +/- 1%) and overexpression of MMPs, was significantly (p < 0.05) ameliorated as a result of saline flushing into the ischemic territory prior to reperfusion. This study has enhanced our understanding of the causal mechanisms by which the neuroprotective effect of ischemic area "flushing" can be achieved.
