The effect of estriol, the third estrogen, was evaluated for its effect on pentylenetetrazole (PTZ)-kindling model of epileptogenesis in mice followed by evaluation on kindling-induced changes in cognitive and motor functions. Kindling was induced by once every 2 days treatment with PTZ (25 mg/kg, i.p.) for 5 weeks. The seizure severity during induction of kindling and percentage incidence of animals kindled at the end of 5 weeks was recorded. Motor function was assessed using a grip strength meter while spatial memory was assessed in a cross maze. Estriol (0.005 and 0.01 mg/kg i.p.) reduced the time for induction of kindling from 5 weeks to 3 and 2 weeks for male and female mice respectively and enhanced the percentage incidence of seizures. Clomiphene (0.9 mg/kg i.p.) delayed the development of kindling and produced anticonvulsant effects. It also partially reversed the proconvulsant effects of estriol. On grip strength test and spontaneous alternation behaviour, a significant decline was observed in kindled mice which was further reduced by pre-treatment with estriol.
