dc.description.abstract | Objective: We aimed to investigate the role of K(v)7 potassium channels in the morphine-induced antinociception in both acute and neuropathic pain models. Methods: Neuropathic pain was induced by partial ligation of the right sciatic nerve. For intracerebroventricular (i.c.v.) injections, each rat was equipped with a permanent cannula. The response to painful thermal stimuli was assessed by the tail-flick test. In sciatic nerve-ligated rats, thermal hyperalgesia was assessed by paw withdrawal latencies in the plantar test and the mechanical hyperalgesia was determined by rigid von Frey filaments. Results: Rats received morphine (2, 5, 20 mu g/10 mu l; i.c.v.) or saline (10 mu l; i.c.v.) 15 min before the tests. In all tests, morphine produced significant antinociceptive effect. When a K(v)7 potassium channel blocker, linopirdine (0.1, 1, 10 mu g/10 mu l; i.c.v.) was administered 15 min before morphine, the effect of i.c.v. morphine in the tail-flick test and plantar test but not in the test with von Frey filaments were prevented. Conclusions: K(v)7 potassium channels contribute to the effect of i.c.v. morphine on acute pain induced by thermal stimulation. In the sciatic nerve-ligated rats, these channels play role in the effect of morphine on thermal hyperalgesia, but not on mechanical hyperalgesia. | en_US |
dc.description.abstract | Akut ve nöropatik ağrı modellerinde morfine bağlı antinosisepsiyonda Kv7 potasyum kanallarının rolünü araştırmayı amaçladık. Materyal ve Metod: Nöropatik ağrı oluşturmak için sağ siyatik sinire parsiyel ligasyon uygulandı. Intraserebroventriküler (i.c.v.) enjeksiyonlar için, her sıçana kalıcı kanül takıldı. Ağrılı termal uyarana yanıt tail-flick testi ile değerlendirildi. Siyatik sinir ligasyonu yapılan sıçanlarda, termal hiperaljezi plantar testte pençe çekme latansı ile, mekanik hiperaljezi ise rijid von Frey filamanları ile değerlendirildi. Bulgular: Sıçanlara testlerden 15 dakika önce morfin (2, 5, 20 µg/10 µl; i.c.v.) veya salin (10 µl; i.c.v.) uygulandı.Tüm testlerde morfin anlamlı antinosiseptif etki gösterdi. Bir Kv7 potasyum kanal blokeri olan linopirdin (0.1, 1, 10 µg/10 µl; i.c.v.) morfinden 15 dakika önce uygulandığında, i.c.v. morfinin tail-flick ve plantar testte görülen etkilerini önlerken, von Frey filamanları ile yapılan test üzerine etkilerini değiştirmedi. Sonuç: Kv7 potasyum kanalları termal stimülasyona bağlı akut ağrıda i.c.v. morfinin etkisine katılmaktadırlar. Siyatik sinir ligasyonlu sıçanlarda, bu kanallar, morfinin termal hiperaljeziye etkisinde rol oynarken, mekanik hiperaljezi üzerine etkisinde rolü yoktur. | tr_TR |
