Abstract

Objectives: We have investigated the modulatory effects of κ-opioid receptors on the central serotonergic system in the hypothalamus, hippocampus and striatum. Materials and Methods: Male Sprague-Dawley rats (n=32) used in the experiments were divided into four groups. Anaesthetized animals were mounted on a stereotaxic apparatus and intracerebroventricularly infused with U-50488H (κ-agonist, 50µg/kg), Nor-BIN (κ-antagonist, 50µg/kg) or U-50488H + Nor-BIN. Control group received saline alone. All animals were decapitated 30 mins after infusions. Hypothalamus, hippocampus and striatum were microdissected and snap frozen. Concentrations of 5-hydroxytryptamin (5-HT) and 5-hydroxyindole acetic acid (5-HIAA, 5-HT metabolite) in these brain regions were determined by HPLC-ECD. Results: 5-HT and 5-HIAA values in the hypothalamus and hippocampus of U-50488H-treated group were significantly decreased compared to control group (p

Abstract

Amaç: Bu çalışma, kappa opioid reseptörlerinin hipotalamus, hipokampus ve striatum'da serotonerjik nörotransmisyon üzerine modülatör etkilerinin araştırılması amacıyla yapıldı. Gereç ve Yöntem: Deneylerde kullanılan toplam 32 erkek Sprague-Dawley sıçan dört gruba ayrıldı. Anestezi altına alınan sıçanlar stereotaksik cihaza yerleştirildikten sonra, U-50488H (κ agonist, 50µg/kg), Nor-Binaltorphimine (Nor-BIN, kappa antagonist, 50µg/kg) veya U-50488H + Nor-BIN intraserebroventriküler (ICV) yolla infüze edildi. Kontrol grubunu oluşturan hayvanlara ise aynı yolla serum fizyolojik uygulandı. ICV infüzyonlardan 30 dk sonra tüm sıçanlar dekapite edilerek beyinleri hızla kuru buz üzerine alındı. Mikrodiseksiyon yöntemiyle hipokampus, hipotalamus ve striatum bölgeleri çıkartılarak sıvı nitrojende donduruldu. Bu beyin bölgelerindeki 5-hydroxytryptamin (5-HT) ve 5-hydroxyindole acetic acid (5-HIAA, 5-HT metaboliti) düzeyleri HPLC-ECD yöntemiyle belirlendi. Bulgular: 5-HT ve 5-HIAA değerleri (ng/gr doku) U-50488H grubu hipotalamus ve hipokampus bölgelerinde kontrol grubuna göre anlamlı derecede azaldı (p
