[ 1 ] - بررسی پاسخهای رفتاری و اثر پیش‌درمانی 801 MK- و مورفین در مدل درد نوروپاتی SNI در موش صحرایی نر بالغ
سابقه و هدف: درد نوروپاتی در نتیجه آسیب به سیستم عصبی ایجاد می‌شود. با توجه به این‌که درمان‌های دارویی برای دردهای نوروپاتیک به‌طور کامل شناخته نشده و درمان‌های دارویی کنونی چندان مؤثر نیست و مطالعات تجربی نشان داده است که MK-801 به عنوان آنتاگونیست گیرنده‌های NMDA در کاهش اثرات ناشی از ضایعه عصب که به دنبال آزاد شدن اسیدآمینه‌های تحریکی حادث می‌شود نقش مهمی دارد؛ در این مطالعه برخی ویژگی‌های ر...
[ 2 ] - بررسی پاسخهای رفتاری و الکتروفیزیولوژی در مدل درد نوروپاتی SNI در موش صحرایی نر بالغ
Background and Aim: Damage to neural pathways is one of the most significant factors of neuropathic pains, which is characterized by spontaneous burning pain accompanied by allodynia and hyperalgesia. The present study was carried out to explore behavioral and electrophysiological characteristics of neuropathic pain model of Spared Nerve Injury (SNI). Materials and Methods: In this experimenta...
[ 3 ] - The effect of chronic caffeine administration on hyperalgesia in a rat neuropathic pain model: role of nitric oxide pathway
Background: Neuropathic pain is a chronic pain caused by damage to the central nervous system and the peripheral. Caffeine is a non-selective antagonist of A1, A2a, receptors of adenosine, which has a protective effect on neuropathic pain in some doses by inhibiting A2a, A2b receptors. Considering that the nitric oxide (NO) levels are apparently effective in the parts of caffeine central effect...
[ 4 ] - Evaluation of the effect of orexin-1 receptors in the nucleus accumbens shell on cost-benefit decision making in male rats
Background: Cost-benefit decision-making is a one of the decision-making models in which the animal achieves a final benefit (reward) by evaluating the cost (effort or delay). The role of different brain regions such as nucleus accumbens in this process has been proven. Orexin is a neuropeptide expressed exclusively by lateral hypothalamus area neurons and orexin-producing neurons project their...
[ 5 ] - Effect of acute caffeine administration on hyperalgesia and allodynia in a rat neuropathic pain model
Introduction: Damage to the central and peripheral nervous system causes neuropathic pain. Caffeine is a plant alkaloid and non-selective antagonist of A1, A2a and A2b adenosine receptors. It is reported that caffeine increases the threshold of pain. In this study, the effect of acute caffeine on behavioral responses of neuropathic pain was investigated. Materials and Methods: The present study...
[ 6 ] - Differential Effects of the Lateral Hypothalamus Lesion as an Origin of Orexin and Blockade of Orexin-1 Receptor in the Orbitoftontal Cortex and Anterior Cingulate Cortex on Their Neuronal Activity
Several studies revealed that orexins may take part in the regulation of the different forms of affective and cognitive processes during wakefulness. The orbitofrontal cortex (OFC) and anterior cingulate cortex (ACC) as an important part of the prefrontal cortex (PFC) have a crucial role in cognitive processes such as reward and decision-making and has a high density of orexin receptor type 1 (...
