[ 6 ] - اثر ضد افسردگی کوئرستین و نانوکریستال کوئرستین در مدل حیوانی بیماری اسکیزوفرنی با استفاده از تست شنای اجباری
اسکیزوفرنی از جمله بیماری‌های تحلیل نورونی می‌باشد که باعث بروز علائم مثبت رفتاری نظیر توهم و علائم منفی نظیر گوشه‌گیری اجتماعی و افسردگی می‌گردد. در واقع افسردگی یک سندرم مهم است که همزمان با بیماری اسکیزوفرنی رخ می دهد. یکی از عوامل پیشرفت این بیماری، عدم تعادل بین رادیکال‌های آزاد و سیستم آنتی‌اکسیدانی است. کوئرستین به عنوان آنتی‌اکسیدانی طبیعی در بسیاری از میوه ها و سبزیجات وجود دارد. هدف ...
[ 7 ] - Olive leaf extract reverses the behavioral disruption and oxidative stress induced by intrastriatal injection of 6-hydroxydopamine in rats
Introduction: Oxidative stress seems to play a critical role in the degeneration of dopaminergic neurons in Parkinson’s disease (PD). Antioxidant compounds can deactivate and scavenge free radical. Olive leaves are considered as a useful source of phenolic compounds. Therefore, this study was designed to investigate the effects of methanolic olive leaf extract (OLE) on neurobehavioral act...
[ 8 ] - Effect of hydroalcoholic extract of Salvia officinalis L. on the activity of catalase and superoxide dismutase in an oxidative stress model created by intracerebroventricular STZ injection in male rats
Introduction: Oxidative stress is the result of imbalance between free radicals and the antioxidant defense mechanisms of the body. Oxidative stress in brain causes dysfunction of brain activities, destruction of neurons, and disorders like Alzheimer disease. In this experimental study, we examined the protective effect of Salvia officinalis L. against oxidative stress induced by intracerebr...
[ 9 ] - Effect of chronic morphine exposure during the neonatal period on the anxiety like behavior of immature rats
Introduction: Several studies have reported anti-anxiety effects of morphine in adult rats. The present study examined the effect of chronic morphine injections in infancy and before puberty on anxiety-like behavior in immature rats. Methods: Neonate rats (n=35) were randomly chosen and divided into two groups. On postnatal days 8-14, one group received saline and the other one received mor...
