Abstract
Amaç: Diyabetik hastalarda duygu-durum hastalıklarının ve kognitif bozukluk insidansının genel popülasyona oranla daha yüksek olduğu bilinmektedir. Bu çalışmada, klinikte antidepresan etkinliği için reçete edilen reboksetin’in sıçanlarda diyabet ile indüklenen davranışsal ve bilişsel değişiklikler üzerine etkinliğinin araştırılması amaçlanmıştır.
Gereç ve Yöntem: Sıçanlarda deneysel diyabet modeli 50 mg/kg tek doz streptozotosin enjeksiyonu (i.v.) ile oluşturulnuştur. Reboksetin tedavisine diyabetik komplikasyonların oluşması için 4 hafta beklendikten sonra başlanmıştır. Deney hayvanlarının depresyon ve anksiyete düzeyleri sırasıyla modifiye zorlu yüzme ve yükseltilmiş artı şekilli labirent testleri ile araştırılmış; kognitif performansları ise Morris su tankı ve pasif sakınma testleri ie değerlendirilmiştir. Hayvanlarının motor aktiviteleri de aktivite kafesi ve Rota-rod testleri ile incelenmiştir.
Sonuç ve Tartışma: Deneyler sonucunda, diyabetik sıçanların depresyon ve anksiyete düzeylerinin yükseldiği ve bilişsel performanslarının zayıfladığı belirlenmiştir. İki hafta süre ile uygulanan reboksetin tedavisi (8 ve 16 mg/kg) diyabetik sıçanların yüksek depresyon ve anksiyete düzeylerini azaltırken, zayıflamış olan bilişsel performanslarını kayda değer ölçüde güçlendirmiştir. Elde edilen bulgular reboksetin’in diyabete bağlı olarak ortaya çıkan davranışsal ve bilişsel bozuklukların tedavisinde terapötik bir potansiyele sahip olabileceğine işaret etmiştir.

Abstract
Objective: The incidence of emotional and cognitive disorders are higher in diabetic patients with respect to the general population. In this study, it was aimed to investigate the efficacy of reboxetine, a clinically prescribed drug for its antidepressant effect, on behavioral and cognitive alterations caused by diabetes in rats.
Material and Method: An experimental diabetes model in rats was induced with a single 50 mg/kg injection of streptozotocin (i.v.). Reboxetine treatment was started 4 weeks after induction of diabetes in order to observe diabetic complications. Depression and anxiety levels of experimental animals were investigated by modified forced swimming and elevated plus-maze tests, respectively; cognitive performances were evaluated by Morris water-maze and passive avoidance experiments. The motor activities of the animals were also examined with the activity cage and Rota-rod tests.
Result and Discussion: Obtained results indicated that the depression and anxiety levels of diabetic rats were increased and their cognitive performances were weakened. Reboxetine treatment (8 and 16 mg/kg) for two weeks reduced the elevated depression and anxiety levels in diabetic rats, while significantly improving their weakened cognitive performance. The findings indicated that reboxetine might possess a therapeutic potential for the cure of behavioral and cognitive impairements concomitant with diabetes.
