Abstract

Hippocampal kindling which have been used to investigate temporal lobe epilepsy can also beused to show the relation between hippocampus and learning procedures. In this study weaimed to investigate the effects of memantine, a non-selective NMDA receptor antagonist, byusing water maze parameters in kindled rats. Adult male Wistar rats were used in 5experimental groups (n=8); Control group (C); Sham group (had a hippocampal electrode buthave no kindling stimulus) (S); Memantine treated group (M); Memantine treated group withkindling stimulus (MKI) and Kindling stimulated group (KI). After memantine treatments andkindling protocols, an acquisition period of 12 day water maze protocol was done in which allgroups performances show a decline of escape latency (EL) and path length (PL) whichindicates that they were able to learn the platform location in a spatial way. EL performanceof M, KI, MKI groups were better than the C group, also the PL performance of M, KI, MKIgroups were better than the C group. After day 9 the difference between the groups weredisappeared. 13th choice day performance which indicates spatial memory of C, M, MKIgroups were not statistically different from each other but for the KI group 13th day EL andPL performances were worse than the others.Our findings indicates that modifying the neuronal plasticity in kindled rats produced aprofound decrease in learning and memory. Memantine improves the changing parameters ofWM learning model in kindling.

Özet

Temporal lob epilepsy modeli olan hippokampal kindling modeli aynı zamanda hipokampusile öğrenme süreçlerinin incelenmesinde de kullanılmaktadır. Biz bu çalışmamızda kindledyapılmış sıçanlarada su tankı parametrelerinini kullanarak selektif olmayan NMDAantagonisti memantinin etkilerini incelemeyi amaçladık. Erişkin wistar türü sıçanlar, hergrupta 8 hayvan olacak şekilde, 5 gruba ayrıldı; Kontrol grubu (K); Sham grubu (hippocampalelektrod takıldı ancak kindling uyarısı almadı)(S); Memantine uygulanan grup (M);Memantine uygulanan ve kindling uyarısı alan grup (MKI) ve Kindling grubu (KI).Memantine tedavileri ve kindling protokollerinin tamamlanmasının ardından 12 günlük sutankı denemelerine geçildi bu denemelerde tüm grupların kaçış zamanı (escape latency (EL))and kaçış mesafesi (path length (PL)) performanslarında platform yerini öğrendiklerinigösteren azalma izlendi. M,KI ve MIK gruplarının EL ve PL performansları K grubundananlamlı düzeyde farklıydı. 9. Günden itibaren gruplar arasındaki farklılık ortadankalkmaktaydı. Karar günü olarak belirlenen 13. üncü gün K, M, MKI arsında anlamlı faklılıkyokken, KI grubunun EL ve PL performansı bozulmuştu.Sonuçlarımız kindling protokolü ile değiştirilen nöronal plastisitenin öğrenme ve belleküzerine etkisini irdelerken, memantinin su tankı parametrelerinde olumlu değişiklik yaptığıgözlenmiştir.
