In the post-genome era. analysis of the cellular transcriptome using microarray or the cellular proteome using a 2-D gel electrophoresis and MALDI-TOF mass spectrometry are most widely used. Stroke is one of the most important causes of death along with cancer and cardiac disease. When pathological change of cells in developed from cerebral ischemia accompanied by stroke administration of neuroprotective drugs before stroke can decreases the degeneration of neuronal cells. The purpose of the present study was to assess the neuroprotective effect and protein expression after administration of P004, middle cerebral artery model of cerebral ischemia in rats. SD rats were subjected to middle cerebral artery occlusion. P004 (1.000 ㎎/㎏) was administered 2 times at 0, 90 minutes after middle cerebral artery occlusion (MCAo). Rats were killed at 48 hours, and infarct area and volume were determined by histology and computerized image analysis. We investigated the protein expression profile on the global ischemia induced by MCAo. This proteomic analysis enable us to identify several proteins differently expressed in infarct brain tissue. The aims of this study were to do investigation comparing the neuroprotection activities of P004 and to understand the mechanism of acted as neuroprotective drug.
