Beneficial effect of insulin on the decreased gastrointestinal ß-adrenergic responses in streptozotocin-diabetic rats: A contributing role of protein biosynthesis
The beneficial effect of insulin on the decreased gastrointestinal ß-adrenergic responses in experimentally diabetic rats has been reported. The effects of streptozotocin-induced diabetes and insulin on the isolated rat ... -
Beta-Adrenergic Responsiveness of the Gastrointestinal-Tract in Diabetic Rats
Öztürk, Yusuf; Altan, Vecdi Melih; Yıldızoğulları, N (Munksgaard Int Publ LTD, 1992)Recently, decreased gastrointestinal beta-adrenergic responses in experimental diabetes have been demonstrated. Gastrointestinal responses to beta-adrenoceptor agonists are impaired in both insulin-dependent and ... -
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 ... -
Calmodulin content and in vitro contractility of duodenum from streptozotocin-induced diabetic rats: Effects of insulin therapy and calmodulin antagonism
Öztürk, Yusuf; Aydın, Süleyman; Özçelikay, A. T.; Altan, Vecdi Melih; YıldızoğluArı, N (Elsevier Science BV, 1997)The effects of experimental diabetes and insulin treatment on the decreased reactivity of isolated rat duodenum to KCI and calmidazolium, a specific calmodulin antagonist, were examined. After 8 weeks of streptozotocin ... -

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 ... -
Diabetic complications in experimental models
Öztürk, Yusuf; Altan, Vecdi Melih; Arı, N. (1998)In this review, the aim is to focus on diabetic complications in experimental models of diabetis. For this purpose, complications, chiefly seen in log-term periods in various systems of animals, such as cardio vascular and ... -
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 ... -
