Abstract

Although, nowadays there are many studies about their features, the metabolic effects of lichens are not exactly explained. Especially in the recent years has been increasing more and more the therapeutic use of lichens along with many studies in the field of alternative medicine. In this research was aimed that of the extract obtained from Usnea longissima Ach. lichen species investigate the effect on rat motility in vitro. In this study was used twenty four piece adult male Sprague Dawley rats. The rats were euthanized by cervical dislocation method under anesthetized. Ileum was isolated by opening abdomen. After the dissection of the ileum, muscle strips were placed 20 ml organ bath that contained Krebs solution. To tissue was applied 1 g tension and incubated for 1 hour period. At the end of the incubation period, acetylcholine (ACh; 10-7, 10-6, 10-5, 10-4, 10-3 M), potassium chloride (KCl; 20, 40, 60, 80, 100 mM) and the various doses of Usnea longissima Ach. extract (0.012, 0.12, 1.2, 12, 120 μg/ml) were applied to bath according to the protocol. The obtained data were evaluated with Turkey test the one-way ANOVA. It was determined that different doses of Usnea longissima Ach. were inhibited to smooth muscle contractility of the rats ileum which was induced by ACh and KCl. It is thought that of the inhibitory effect to ACh responses of Usnea longissima Ach. may be through muscarinic mechanism and also of the inhibitory effect to KCl responses may be through L-type voltage-sensitive calcium (Ca2+) channels.

Özet

Günümüzde likenlerin özellikleri ile ilgili birçok çalışma bulunmasına rağmen metabolik etkileri tam olarak ortaya konulamamıştır. Özellikle son yıllarda alternatif tıp alanında yapılan birçok çalışmayla beraber likenlerin terapotik kullanımları gittikçe artmaktadır. Bu araştırmada Usnea longissima Ach. liken türünden elde edilen ekstraktın in vitro rat ileum motilitesi üzerine etkisinin araştırılması amaçlandı. Bu çalışmada 24 adet erkek ergin Sprague Dawley cinsi rat kullanıldı. Ratlar anestezi altında servikal dislokasyon metodu ile ötenazi edildi. Ratların abdomenleri açılarak ileum izole edildi. İleumun temizliği yapıldıktan sonra hazırlanan kas şeritleri, içerisinde Krebs solüsyonu bulunan 20 ml’lik organ banyosuna yerleştirildi. Dokuya 1 gram (g) gerim uygulanarak 1 saatlik inkübasyon periyoduna bırakıldı. İnkübasyon periyodu sonunda banyoya asetilkolin (ACh, 10-7, 10-6, 10-5, 10-4, 10-3 M), potasyum klorür (KCl, 20, 40, 60, 80, 100 mM) ve Usnea longissima Ach. ekstraktı çeşitli dozlarda (0.012, 0.12,1.2, 12, 120 μg/ml) bir protokol çerçevesinde uygulandı. Elde edilen değerler one way ANOVA’da Tukey testi ile değerlendirildi. Usnea longissima Ach.’nın farklı dozlarının, ACh ve KCl ile indüklenen in vitro rat ileum düz kas kontraktilitesini inhibe ettiği belirlendi. Usnea longissima Ach.’nın ACh cevaplarını baskılayıcı etkisinin muskarinik mekanizma üzerinden, KCl cevaplarını baskılayıcı etkisinin ise voltaja duyarlı L tipi kalsiyum (Ca2+) kanalları üzerinden olabileceği düşünülmektedir.
