objective(s):ischemia is described as organs and tissues are destitute of oxygen due to decreased arterial or venous blood flow. many mechanisms play role in cell death happened as a consequence of a new blood flow is needed for both cell regeneration and to clean toxic metabolites during ischemia and later. lung damage induced by ischemia/reperfusion (i/r) is a frequent problem in lung transpl...
Edaravone is clinically used for treatment of patients with acute cerebral infarction. However, the effect of double application of edaravone on neurogenesis in the hippocampus following ischemia remains unknown. In the present study, we explored whether pre- and posttreatment of edaravone had any effect on neural stem/progenitor cells (NSPCs) in the subgranular zone of hippocampus in a rat mod...
Abstract Background: Stroke is the second leading cause of death in the world and has irreversible consequences. Cerebral ischemia/reperfusion (I/R) through production of oxidants and inflammatory markers causes apoptosis of brain neurons. On the other hand, in various studies, the antioxidant and anti-inflammatory effects of the Malva neglecta have been proven. Therefore, in this study, we inv...
Background: Stroke is the third leading cause of invalidism and death in industrialized countries. There are conflicting reports about the effects of Angiotensin II on ischemia-reperfusion brain injuries and most data have come from chronic hypertensive rats. In this study, hypotensive and non-hypotensive doses of candesartan were used to investigate the effects of angiotensin II AT1 receptor b...
Stroke patients comprise a large number of patients with a highly significant degree of cerebral ischemia that is best exemplified by the transient focal ischemia models in experimental animals such as rat and mouse. Mechanisms include bioenergetic failure and loss of cell homeostasis, and also acidosis, excitotoxicity and disrupted blood-brain barrier [1]. A central issue is the series of set ...
Sodium 4-phenylbutyrate (4-PBA) is a low molecular weight fatty acid that has been used for treatment of urea cycle disorders in children, sickle cell disease, and thalassemia. It has been demonstrated recently that 4-PBA can act as a chemical chaperone by reducing the load of mutant or mislocated proteins retained in the endoplasmic reticulum (ER) under conditions associated with cystic fibros...
Gastrodin (GAS), which is extracted from the Chinese herbal medicine Gastrodia elata Blume, has long been used to improve stroke, epilepsy, dizziness and dementia. However, the effects and underlying mechanisms of GAS on subacute phase cerebral ischemia‑reperfusion (I/R) injury remain unknown. The aim of the present study was to investigate the effects and mechanisms of GAS on cerebral I/R inju...
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 neuroprote...
conclusions our findings indicate that fullerenol nanoparticles decrease the brain infarction through enhancement of the sod activity during cerebral ischemia-reperfusion injury. results occlusion of mca induced considerable infarction and lesion in ischemic hemispheres of control ischemic rats (527 ± 59 mm3) in accompany with a decrease in the glutathione content (45%), and sod activity (29%) ...
