[ 1 ] - The Effect of Epigallocatechin gallate on Morphine Induced Working Memory Defects in Rats: An Experimental Study

Background and Objectives: Chronic morphine use leads to structural changes in the brain. Some studies have shown the antioxidant and neuroprotective effects of Epigallocatechin gallate (EGCG) as a main polyphenol of green tea. Therefore, the aim of this study was to investigate the effect of EGCG on working memory in morphine-treated rats. Materials and Methods: In this experimental study, 32...

[ 3 ] - Pretreatment effects of metformin on behavioral manifestations of global ischemia/reperfusion injury in rats

Introduction: Metformin (MET) as an oral antidiabetic drug has pleiotropic effects such as antioxidative and neuroprotective properties. In the current study we aimed to investigate the probable effects of Pretreatment MET therapy in global ischemia-reperfusion in rats. Materials and Methods: In this study, 40 male Wistar rats (200-220 g) were used. Animals were randomly divided into four g...
