Administration of rapamycin in doses of 0.3; 1.0 and 3.0 mg/kg, i.p. resulted
in a dose-dependent
decrease in the severity of kindled convulsions. Statistical significance was achieved at a dosage of 1.0 mg/kg
(Table 1), at which dose 6 of 9 animals were protected against stage 4-5 seizures (p<0.05) as compared with
control. When administered in a 3.0 mg/kg dose,
rapamycin completely prevented the development of stage
4-5 convulsions.
Administration of valproic acid to kindled animals (50.0; 100.0 and 250.0 mg/kg, i.p.) resulted
in
a
dose-dependent seizure-protecting effect that was statistically significant for two doses, 100.0 and 250.0
mg/kg (Table 1) as compared with controls (P<0.001). Both doses prevented stage 5 seizures in all animals,
while the higher dosage (250.0 mg/kg) completely prevented generalized clonic-tonic seizures (stage 4 and 5)
(Table 1).
