چکیده مقاله:

Statins are inhibitors of HMG-CoA reductase and inhibit cellular synthesis of cholesterol and isoprenoids. Studies have previously demonstrated theanti-inflammatory and vasoprotective effects of statins on cultured brain cells (astrocytes and microglia) and endothelial cells. Atorvastatin also prolonged latency(time to appearance of spike potentials) and diminished the amplitude and frequency of spike potentials, which indicate epileptic discharges. In some studies observedthat pre-treatment with atorvastatin efficiently reduced seizure activities, hippocampal neuron death, monocyte infiltration and proinflammatorygene expression.In this study the protective effects of atorvastatin on seizures induced by entylenetetrazole(PTZ) and maximal electroshock stimulation (MES) were investigated. Intraperitoneal pentylenetetrazole was used to induce seizures in mice. It was found thatatorvastatin (ED50=5.12±0.98) has antiseizure effects comparing to control group. Atorvastatin treatment significantly increased the seizure threshold (p<0.01) and decreased the incidence of tonic seizure and death which is induced by intraperitoneal pentylenetetrazole.The effect of atorvastatin on seizure induced by MES in mice was evaluated and the results demonstrated that it is not able to produce anticonvulsant activity.
