Objective(s): According to recent the findings, sulfur dioxide (SO2) is produced by the cardiovascular system, influencing some major biological processes. Based on previous research, SO2 exhibits antioxidant effects and inhibits apoptosis following cardiac ischemia/reperfusion. Therefore, the objective of the current study was to examine the neuroprotective impact of SO2 following global cereb...

Abstract: Background: Neuroprotection is one of considerable interest in search novel therapies to improve ischemic brain damage the present scenario. The objective investigation study actions Talinum triangulare cerebral ischemia/reperfusion induced oxidative stress Wistar rats and in-vitro antioxidant actions. Methods: Four different groups adult are selected for where group III IV treated 15...

Introduction: Oxidative stress plays a crucial role in the impairment of synaptic plasticity following cerebral ischemia which ultimately results in memory dysfunction. Hence, application of antioxidant agents could be beneficial in the management of memory deficit after brain ischemia. Minocycline is a tetracycline antibiotic with antioxidant effect. The main objective of this work was to asse...

Objective(s): The alteration of glucose transporters is closely related with the pathogenesis of brain edema. We compared neuronal damage/death in the hippocampus between adult and young gerbils following transient cerebral ischemia/reperfusion and changes of glucose transporter-1(GLUT-1)-immunoreactive microvessels in their ischemic hippocampal CA1 region. Materials and Methods: Transient cere...

background: the role of renin angiotensin system (ras) in ischemic/reperfusion (i/r) injuries is not fully elucidated. furthermore, it is not clear whether inhibition of ras by angiotensin-converting enzyme (ace) inhibitors has beneficial effects in terms of protecting the brain from i/r injuries. in this study enalapril is used as an ace inhibitor to evaluate the role of ras in i/r injuries in...

Objective(s) The brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. The hippocampus is highly vulnerable to ischemic insults, particularly the CA1 pyramidal cell layer. There is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. Previous studies reported that pentoxifylline (PTX) has a neuroprot...

background: angiotensin ii (ang ii) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. this study evaluated the role of central ang ii by using candesartan, as an at1 receptor blocker, in the brain edema formation and blood-brain barrier (bbb) disruption caused by ischemia/reperfusion (i/r) injuries in rat. methods...
