[ 1 ] - اثر استرس روانی مزمن کوتاه و میان مدت بر پارامترهای متابولیکی، هورمونی و رفتاری در موش های صحرایی نر
زمینه و هدف: استرس به خصوص نوع روانی مزمن موضوع مهم جامعه مدرن ما است. در این راستا در مطالعه حاضر اثر استرس روانی مزمن بر پارامترهای متابولیکی، هورمونی و رفتاری بررسی شده است. مواد و روش ها: نوع مطالعه حاضر مداخله ای تجربی می باشد. حیوانات به گروه های کنترل و آزمایش و سپس هر گروه به دو زیر گروه 15 و 30 روزه (در هر زیرگروه 7 سر) تقسیم شدند. استرس توسّط دستگاه جعبه ارتباطی القا شد. این دستگاه شا...
[ 2 ] - اثرات استرس جداسازی از مادر در دوران شیرخوارگی بر هومئوستاز گلوکز در موش‌های صحرایی نر بالغ
هدف: مواجهه با استرس در دوران شیرخوارگی ریسک ابتلا به اختلالات متابولیک، رفتاری و سایکولوژیک در دوره‌های بعدی زندگی را افزایش می‌دهد. در این راستا مطالعه حاضر به بررسی اثر استرس جداسازی از مادر بر غلظت‌های پلاسمایی گلوکز و انسولین و شاخص HOMA-IR (شاخص مقاومت به انسولین) در موش‌های صحرایی نر بالغ پرداخته است. مواد و روش‌ها: حیوانات پس از تولد به دو گروه "با استرس" و "بدون استرس" تقسیم شدند. حیوا...
[ 3 ] - Effects of Memantine, an NMDA Antagonist, on Metabolic Syndromes in Female NMRI Mice
Introduction: The brain glutamate neurotransmitter system and its NMDA receptors in the nucleus accumbens play an important role in the incidence of the phenomena of sensitivity and addiction. The present study examined the inhibitory effect of glutamate NMDA receptors in the nucleus accumbens in response to chronic stress. Methods: After the unilateral and bilateral cannula placement in the ...
[ 4 ] - Comparison of effect of intraperitoneal vs. intra-accumbal injection of memantine on response to acute stress in female NMRI mice
Introduction: In this study, the effect of memantine administration into the nucleus accumbens on the metabolic changes induced by acute stress in female mice was evaluated. Methods: Intra-accumbens unilateral or bilateral canulation was performed. One week after recovery, a group of animals were given memantine (1, 0.5, and 0.1 μg/mouse) five min before stress induction intra-accumbally, an...
[ 5 ] - The Effect of Maternal High-Fat Feeding on Energy Homeostasis in Stressed Adult Male Rat Offspring
Introduction: In the present study the effect of chronic maternal high-fat diet consumption on energy homeostasis and glucose metabolism in response to chronic stress was investigated in adult male rats. Materials and Methods: Female rats were divided into two groups of normal and high fat diets. Each group received their diet from 3 weeks before pregnancy until the end of lactation. At 8 weeks...
[ 6 ] - Histological Evaluation of Pancreas Following Early Life Stress in Exposure to Pubertal Stress in Male Rats
Background and purpose: Stressful events in early-life induce metabolic disorders in adolescence. The aim of this study was to investigate the effect of early-life stress on number or area of Langerhans islets in exposure to foot-shock and psychological stress in male rats. Materials and methods: The rats were divided into six groups: control (without stress), early-stress (stress at 2 weeks o...
