The Effects of Glyburide and Insulin on the Decreased Beta-Adrenergic Responsiveness of the Gastrointestinal-Tract in Rats With Non-Insulin-Dependent Diabetes
Öztürk, Yusuf; Yıldızoğulları, N; Özüarı, A; Altan, Vecdi Melih (Pergamon-Elsevier Science LTD, 1994)1. Decreased beta-adrenergic responses have been reported in gastro-intestinal tract of rats with diabetes mellitus. Effects of glyburide and insulin on the decreased beta-adrenergic responsiveness of the gastro-intestinal ... -
Evaluation of Contraction Time and Recovery Period as a Parameter in the Calcium Antagonistic Action on the K+-Depolarized Rat Duodenum
Öztürk, Yusuf; Altınkurt, Onur; Yıldızoğulları, N; Altan, Vecdi Melih (Royal Pharmaceutical Soc Great Britain, 1990)Verapamil, nifedipine, phentolamine, tolazoline, gentamicin and neomycin inhibited calcium-induced contractions of K+-depolarized duodenum of the rat by shifting the concentration-response curves to the right. Non-competitive ... -
Increased Alpha(1)-Adrenergic Responsiveness of Alloxan-Diabetic Rat Atria - Effects of Insulin Therapy and Thyroidectomy
Lafçıerol, D; Altan, Vecdi Melih; Öztürk, Yusuf (Pergamon-Elsevier Science LTD, 1994)1. Experimental models of diabetes are increasingly used for the investigation of cardiovascular complications as well as other complications due to diabetes mellitus. However, animal models have been used in relatively ... -
Insulin action on different smooth muscle preparations
Altan, Vecdi Melih; Öztürk, Yusuf; Yıldızoğlu-Arı, N.; Nebigil, C.; Lafçi, D.; Özçelikay, A. T. (1989)1. 1. The importance of insulin in diabetic gastro-intestinal complications has been postulated. The present study was designed to investigate short-term effect of insulin on different smooth muscles isolated from non-diabetic ... -
Linear Modeling of the Effect of Intravenous Histamine Infusion on Rat Gastric-Acid Secretion - a Biostatistical Evaluation By Splitting the Time-Effect Curves
Öztürk, Yusuf; Özçelikay, A. T.; Altan, Vecdi Melih; Altınkurt, O (J R Prous Sa, 1991)Lumen perfusion experiments have been widely employed for the evaluation of gastric acid secretion in rats. The advantage of the lumen perfusion models is the simplicity in evaluating the effectiveness of secretagogues and ... -
Pharmacological effects of rutin
It is well-known that flavonoids including rutin exert a wide range of pharmacological effects. This study was carried out for further characterization of the pharmacological effect of rutin. A significant rise in the serum ... -
Vanadate Treatment Reverses Gastrointestinal Complications in the Streptozotocin-Diabetic Rats
Öztürk, Yusuf; Yıldızoğulları, N; Pekiner, C; Özçelikay, At; Altan, Vecdi Melih (Elsevier Science Inc, 1994)1. Insulin-like effects of vanadium compounds have been reported in various experimental conditions. Effects of vanadate on the decreased beta-adrenergic responsiveness of the rat duodenum due to streptozotocin diabetes ... -
ß-Adrenergic Responsiveness of the Gastrointestinal Tract in Diabetic Rats
Abstract: Recently, decreased gastrointestinal ß-adrenergic responses in experimental diabetes have been demonstrated. Gastrointestinal responses to ß-adrenoceptor agonists are impaired in both insulin-dependent and ...
