ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of beta-asarone on expression of immediately early gene c-fos in kindling epilepsy rat brain.</p><p><b>METHOD</b>The rats were randomly divided in to beta-asarone groups (200, 100, 50 mg x kg(-1) x d(-1)), difetoin control group (36 mg x kg(-1)) and model group. The remedy was administered orally. The effects were observed in kindling epilepsy model induced by penicillin, then the expression of c-fos were determined by western blot (hippocampus) and immunohistochemical techniques (cortex).</p><p><b>RESULT</b>Beta-asarone could significantly increase the expression of c-fos in kindling epilepsy rat brain, and show its quantity-effect relation. The expression of c-fos in hippocampus was (1139.45 +/- 155.56), (1109.56 +/- 134.03), (1103.73 +/- 235.82) CNT x mm2 in beta-asarone groups, 920.54 +/- 203.20 in model control group, and 1106.26 +/- 186.24 in difetoin group, respectively. The number of c-fos positive cell was 87.1 +/- 2.2, 76.3 +/- 1.3 and 59.9 +/- 1.3 in beta-asarone groups, 39.3 +/- 2.6 in model control group, and 95.2 +/- 1.1 in difetoin group, respectively.</p><p><b>CONCLUSION</b>Beta-asarone can obviously increase the expression of c-fos in epilepsy rat brain. It is one of important response to epilepsy.</p>

<p><b>OBJECTIVE</b>To study the effects of Annao tablet (main component is beta-asarone) on S100B and NPY of cortex in chronic epilepsy rats.</p><p><b>METHOD</b>The remedy was administered orally. The effects were observed in convulsion model induced by PG, then S100B protein and NPY of cortex were determined.</p><p><b>RESULT</b>Annao tablet could depress the epileptic degree, postpone spasm latent period and reduce the wet dog sample (WDS) times. The remedy could decline S100B and NPY of cortex in chronic epilepsy rats.</p><p><b>CONCLUSION</b>Annao tablet has obvious antiepileptic effects and can reduce the nerve cell damage induced by epilepsy.</p>
