Abstract/OtherAbstract:
A method for in vivo evaluation of lipid peroxidation in the extracellular space of anaesthetized rat brain cortex was developed. This method involved the use of microdialysis perfusion and high-performance liquid chromatography. The microdialysates, eluted from implanted probes, were reacted with thiobarbituric acid (TBA) prior to analysis by an HPLC system equipped with a fluorescence detector (excitation and emission wavelengths were 515 and 550 nm, respectively). Lipid peroxidation in the extracellular space was evaluated as the concentration of malondialdehyde, a lipid peroxidation end product which reacts with TBA to form a fluorescent conjugate. Significantly increased production of malondialdehyde following hydrogen peroxide perfusion (0.03%, 0.3% at a flow-rate of 1 microl/min) was observed in the brain cortex of anaesthetized rats.
