After eight weeks, diabetic and nondiabetic rats were orally treated with DMF (25 or 100 mg/kg/day) or vehicle for four weeksorally. At 12 week after diabetes induction, in vitro organ bath studies were performed on detrusor strips of each rat and the contractileresponses to KCl and carbachol (CCh) of the strips were evaluated.Results: The maximal KCl (80 mM)- and CCh-induced contractile responses of detrusor strips significantly (p KW - Bladder KW - Carbachol KW - Contraction KW - Detrusor muscle KW - Diabetic complication KW - Dimethyl fumarate KW - Streptozotocin N2 - potansiyel etkisi araştırıldı.Gereç ve Yöntemler: Yetişkin erkek Sprague Dawley sıçanlara diyabet indüksiyonu için tek doz intraperitoneal streptozotosin (60 mg/kg) verildi. Sekiz hafta sonra, diyabetik ve diyabetik olmayan sıçanlara dört hafta boyunca oral DMF (25 veya 100 mg/kg/gün) veyataşıyıcı tedavileri uygulandı. Diyabet indüksiyonundan 12 hafta sonra, her bir sıçanın detrüsör şeritleri üzerinde in vitro organ banyosuçalışmaları yapıldı ve şeritlerin KCl ve karbakol (CCh) ile indüklenen kasılma yanıtları değerlendirildi.Bulgular: Detrüsör şeritlerinin KCl (80 mM) ve CCh ile indüklenen maksimum kasılma yanıtları, diyabetik grupta (sırasıyla 84,35±13,56ve 178,80±29,66 mg gerim/mg doku) kontrol grubuna (sırasıyla 175,10±13,42 ve 399,40±77,63 mg gerim/mg doku) göre önemli ölçüdeazaldı (p CR - 1.
