  • Title: Changes in cerebral free fatty acids and triacylglycerols in focal cerebral ischemia.
    Author: Kubota M, Kitahara S, Narita K, Tamura A, Sano K, Shimasaki H, Ueta N.
    Journal: Int J Biochem; 1990; 22(11):1269-72. PubMed ID: 2257951.
    Abstract:
    1. Focal cerebral ischemia was induced in anesthetized rats by occluding the stem of the proximal middle cerebral artery. 2. The levels of free fatty acids, such as stearic and arachidonic acids, in the ischemic cerebral cortex increased progressively until 60 min after occlusion, but thereafter they decreased rapidly. 3. In contrast to the time-dependent changes in free fatty acids, the levels of triacylglycerol (TAG) in the ischemic cerebral cortex continued to increase for 120 min after occlusion. Increases in TAG-palmitate, -stearate and -arachidonate accounted for the increase in the triacylglycerol level. 4. The pattern of the lipid changes in focal cerebral ischemia differs from those reported in bilateral diffuse cerebral ischemia induced by arterial occlusion or in decapitation ischemia.
