Noradrenalinin İn Vitro Koşullar Altında Besi Hindilerinde İnce ve Kalın Bağırsak Düz Kasları Üzerine Etkisi

Bu çalışmanın amacı heavy hybrid hindilerin ince ve kalın bağırsaklarındaki düz kaslarda bulunan adrenerjik reseptörlerin olası varlığını in vitro koşullar altında farklı konsantrasyonlarda non-selektif adrenerjik reseptör agonisti, noradrenalin, kullanarak belirlemektir. Çalışma 24 besi hindisinde gerçekleştirildi. Organ izolasyon cihazında duodenum, jejunum, ileum, çekum ve kolonun müsküler longitudinal ve sirküler tabakalarında testler farklı konsantrasyonlarda noradrenalin hydrogentartarate solüsyonu kullanılarak test edildi. Çalışma besi hindilerinin ince ve kalın bağırsaklarındaki düz kaslarda bulunan adrenerjik reseptörlerin olası varlığını ortaya koymdu. Noradrenalin’in longitudinal tabaka üzerindeki etkisi, besi hindilerinin ince ve kalın bağırsaklarında ki tunica muscularis sirküler tabaka üzerinde ki etkisinden daha güçlüydü (P

Effects of Noradrenaline on Smooth Musculature of Small and Large Intestines of Fattening Turkey Under In Vitro Conditions

The aim of the study was to determine the possible presence of adrenergic receptors in the smooth musculature ofsmall and large intestines of heavy hybrid turkey, using different concentrations of non-selective adrenergic receptoragonists, noradrenaline, under in vitro conditions. The research was carried out on 24 fattening turkeys. Tests of circular andlongitudinal layers of muscular duodenum, jejunum, ileum, cecum and colon in the organ isolation apparatus, using differentconcentrations of noradrenaline hydrogentartarate solution, were tested. The research has established the presence ofadrenergic receptors within the smooth musculature of the small and large intestines of fattening turkeys. The effect of thenoradrenaline on the longitudinal layer was stronger (P
