Electrocardiographic Evaluation of Acute Restraint and Cold Restraint Stress Response in Rats
نویسندگان
چکیده
Bu çalışmada, akut kısıtlama stresi ve soğuk stresinin sıçanlarda elektrokardiyografik (EKG) parametreler üzerindeki etkilerini araştırıldı. Toplam 18 adet 8-10 haftalık, ağırlıkları 180-220 g olan erkek Wistar albino rat üç eşit gruba (n=6/grup) ayrıldı. Kontrol grubundaki ratlara stresör uygulanmadı. Kısıtlama ratlar 2 saat kısıtlayıcıda tutuldu. Soğuk tutma kısıtlayıcı içinde +4°C'de Sıçanlarda Televet II EKG cihazı (Kruuse, Almanya) ile ketamin ksilazin anestezisi altında kaydı yapıldı derivasyonların analizinde 100 programı (versiyon® 7.0.0, Kruuse, Heusenstamm, kullanıldı. PR, QT, QRS intervalleri R dalgası amplitüdü gruplar arasında anlamlı fark yoktu (p >0,05). Ancak, kalp atım hızı grubunda kontrol grubuna

acute cold / restraint stress in castrated rats
objective: the present study aimed to determine whether castration altered osmotically stimulated vasopressin (vp) release and urinary volume and what is the role of endocrine-stress axis in this process. materials and methods: totally 108 mice were studied in two main groups of castrated (n=78) and control (n=30). each group was extracted by acute cold stress (4◦c for 2h/day), restraint stress...
متن کاملEffects of stress transmission pathways on acute ulcerogenesis in rats under cold-restraint stress.
The effect of autonomic nerve and pituitary-adrenal pathways of stress transmission on stressinduced acute gastric ulceration was studied using splanchnicotomized (Sp), truncal vagotomized (TV) and splanchnicotomized plus vagotomized (Sp + TV) rats. Cold-restraint stress was loaded for 30, 60 and 120 min. With normal rats as a control group, the change in incidence of gastric mucosal lesions, c...
متن کاملSpatial memory under acute cold and restraint stress.
This study examined spatial memory as measured by radial arm maze (RAM) performance after exposure to two stress conditions and a normothermic-unrestrained control condition. Male Fischer 344 rats were trained on the win-shift RAM procedure for 7 days, by which time they achieved asymptotic performance. The next day, rats in the two stress groups were exposed to 15 min of restraint in either 37...
متن کاملEffects of Acute and Chronic Restraint Stress on Reinstatement of Extinguished Methamphetamine-induced Conditioned Place Preference in Rats
Introduction: Methamphetamine (METH) is a neurotoxic psychostimulant with highly addictive potential that leads to compulsive drug use and vulnerability to relapse. Environmental cues, such as drug exposure, peer influence, and social stress, are the powerful triggers of drug relapse. In this study, we tried to find out the effect of acute and chr...
متن کاملImpaired passive avoidance acquisition in Sprague-Dawley and Lewis rats after restraint and cold stress.
The study examined the effects of restraint combined with cold water stress (IMO+C) on learning and memory of Sprague-Dawley (S-D) and Lewis (LE) rats in the passive avoidance task. The procedure started with 6 days of adaptation to the apparatus during which the recorded latencies to enter the dark compartment were used to assess the process of habituation. On the training day rats were expose...
