Altered Alpha-Adrenergic Responses of Vas-Deferens to Noradrenaline and Tyramine From Rats With Short-Term and Long-Term Alloxan Diabetes
Öztürk, Yusuf; Yıldızoğulları, N; Altan, Vecdi Melih (Pergamon-Elsevier Science LTD, 1994)1. Functional and morphological abnormalities in vas deferens have been reported by both experimental and clinical studies as a cause of genital function abnormalities in diabetic males. 2. In the present study, contractile ... -
Bradykinin Receptors in Intestinal Smooth Muscles and Their Postreceptor Events Related to Calcium
Öztürk, Yusuf; Altan, Vecdi Melih; Yıldızoğulları, N; Altınkurt, O (Hindawi LTD, 1993)THE effects of trifluoperazine and verapamil on bradykinin- and des-Arg9-bradykinin induced responses of isolated rat duodenum and guinea-pig ileum were investigated to elucidate post-bradykinin receptor events. Verapamil ... -
Decreased gastro-intestinal responses to salbutamol and serotonin in streptozotocin-induced diabetes: Improving effect of insulin in vivo and in vitro
Yıldızoğlu-Arı, N.; Altınkurt, Onur; Öztürk, Yusuf; Altan, Vecdi Melih; Pekiner, C.; Karasu, Ç. (1988)1. 1. Decreased gastro-intestinal responses to salbutamol (sal) and serotonin (5-HT) in experimental diabetes have been postulated. The present study was designed to investigate whether in vivo and in vitro insulin treatments ... -
Duration-dependent changes in calcium responsiveness in the alloxan-diabetic rat intestine
Öztürk, Yusuf; Altan, Vecdi Melih; Yıldızoğlu-Arı, N. (Elsevier Science Inc, 1996)Disturbances of the gastrointestinal tract that are common in diabetes mellitus seem to be related to intestinal motility. In experimental models of diabetes, decreased calcium sensitivity has been demonstrated in various ... -
Effect of Insulin on the Decreased Beta-Adrenergic Responses of Duodenum and Atrium Isolated From Streptozotocin Diabetic Rats
Öztürk, Yusuf; Yıldızoğulları, N; Altan, Vecdi Melih; Özçelikay, At (Pergamon-Elsevier Science LTD, 1993)1. Decreased beta-adrenergic responses have been reported in both gastro-intestinal tract and atrium of experimentally-induced diabetic rats. The present study was undertaken to investigate in vitro effects of insulin on ... -
Effect of Short and Long-Term Streptozotocin Diabetes on Smooth-Muscle Calmodulin Levels in the Rat
Öztürk, Yusuf; Aydın, Süleyman; Altan, Vecdi Melih; Yıldızoğlu-Arı, Nuray; Özçelikay, At (Churchill Livingstone, 1994)Diabetes mellitus is a metabolic disease associated with certain complications which have also been demonstrated in the experimental models of this disease. Altered responses to several agonists have been reported in various ... -
The Effect of Vanadate on Alloxan-Diabetic Rat Atria
Özçelikay, At; Yıldızoğulları, N; Özüarı, A; Öztürk, Yusuf; Altan, Vecdi Melih (Elsevier Sci Ireland LTD, 1993)In this study, we examined the effect of vanadate treatment on cardiac changes recognized in diabetic rats. In addition, the possible contribution of thyroid hormones to vanadate's effect on alloxan-diabetic atria was also ... -
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 ... -
