| Outline of Final Research Achievements |
We performed nuclear magnetic resonance (NMR) analysis for rat postmortem cerebrospinal fluid (CSF) and ascertained if presence and absence of antemortem seizure could be detected. Male Sprague-Dawley rats (9 weeks, 220 g) were randomized into four groups. 1) seizure group (n=13); saline (12mL/kg) ip + pentylentetrazole (PTZ) (70 mg/kg) ip 6 hrs later, 2) seizure suppression group (n=10); pentobarbital (PB) (90mg/kg) ip + PTZ ip 6 hrs later, 3) anticonvulsant alone group (n=13); PB ip + saline (1.75mL/kg) ip 6 hrs later, 4) control group (n=9); saline + saline ip 6 hrs later. After animals were euthanized by CO2 gas, CSF samples collected in the cisternal compartment were analyzed by proton NMR spectroscopy. The NMR spectral profile of 4 groups showed separation and clustering on a PCA score plot.
