全ての実験は、Guidelines of the local Ethical Committee for Animal Experimentationに従って行った。
海馬切片におけるてんかん様反応:ラット海馬切片の潅流の、正常ACSFからHKLCFへの変更によって、定電流による海馬采の刺激に反応して、CA3領域においててんかん様FPが次第に増加した。HKLCF単独に曝露された対照切片において、PS1振幅は連続的に増加し、20分以内にプラトー値に達し(4.250.77mV)、ACSF潅流下で記録したもののほぼ2倍高かった(2.180.15mV;n=10個の切片についてのmeans.d.)。また、定電流の単一の刺激によって誘発された反復性PSのバースト(すなわち、PS2、PS3など)は、HKLCF潅流の最初の30分において、誘発されたバースト毎に単一のPS1から平均7.62.3PSに数が著しく増加し、記録の終わりまで僅かに増加し、HKLCFの80分の潅流後に誘発されたバースト毎に平均8.81.6PSに達した。ブリバラセタム及びレベチラセタムの両方は、これらのてんかん様反応を減少させた。HKLCFの15分の潅流によって、自発的電場バーストは、HKLCF単独に曝露された10個の対照切片のうち4個において起こり、一方HKLCF中で25分から記録の終わりまで、全ての対照切片は、通常の電場バーストを示した。レベチラセタム(32M)ではなく、ブリバラセタム(3.2M)は、この自発的バーストの速度を減少させた。
