Time course of lipid peroxidation during incomplete ischaemia followed by reperfusion in rat brain.
The time course of lipid peroxidation was studied in the rat brain cortex after ischaemia and reperfusion. The ischaemia was induced by 4-hour occlusion of both common carotid arteries and was followed by reperfusion of different duration (10, 30 or 60 min). The extent of lipid peroxidation was determined by measurement of conjugated dienes (CD) and TBA reactive products. Maximal values of CD and TBA reactive products were found after 10- and 30-minute reperfusion. This indicated the most suitable time interval for studying the effect of antioxidants and oxygen radical scavengers in this model of brain ischaemia.
