The present study was designed to investigate the possible properties of the injured brain neurocytes, the expression of heat shock protein70 (HSP70) and Fas protein after acute local ischemia brain injury and local cerebral ischemia-reperfusion injury in rats and to investigate the protecting mechanism of puerarin on the brain neurocytes of rats in acute local ischemia brain injury and local c...

Serofendic acid is a low-molecular-weight compound extracted from fetal calf serum. We previously reported that intracerebroventricular administration of serofendic acid prevents cerebral ischemia-reperfusion injury. However, the effect of peripheral administration of serofendic acid on cerebral ischemia-reperfusion injury has not been examined. In the present study, we investigated the effect ...

Background: The steroidal alkaloids incurring great interest because of their various pharmacological properties that isolated from various species. The aim of this investigation has been to studying of the effects of Steroidal alkaloids isolated from olive leaf on cerebral ischemic – induced inury on rats. Materials and methods: In this experimental study, 48 male wistar rats divided to s...

objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

BACKGROUND AND PURPOSE Superoxide anion radicals (O2*-) are implicated in ischemia/reperfusion injury, although a direct relationship has not been elucidated. Recently, a specific method of hydroethidine (HEt) oxidation by O2*- was developed to detect O2*- production in a variety of experimental brain injury models. To clarify the role of O2*- in the mechanism of ischemia/reperfusion, we invest...

pervious studies have shown that pentoxifylline (ptx) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. however, there is very little and controversial information about the effect of ptx on brain edema in cerebral ischemia. therefore, the aim of this study was to determine the effects of different doses of ptx on brain edema and neurological motor...

Heat-sensitive moxibustion has neuroprotective effects against focal cerebral ischemia/reperfusion injury, however its mechanism of action remains unclear. In this study, rat models of focal cerebral ischemia/reperfusion injury were treated with suspended moxibustion at acupoint Dazhui (DU14) for 35 minutes. Results showed that suspended moxibustion decreased infarct volume, reduced cortical my...

We investigated the role of the Wnt signaling pathway in cerebral ischemia/reperfusion injury by examining β-catenin and glycogen synthase kinase-3β protein expression in the rat hippocampal CA1 region following acute cerebral ischemia/reperfusion. Our results demonstrate that cell apoptosis increases in the CA1 region following ischemia/reperfusion. In addition, β-catenin and glycogen synthase...

Established therapies for cerebral ischemia-reperfusion injury are currently limited. The urinary trypsin inhibitor ulinastatin (UTI) is considered cytoprotective against ischemia-reperfusion injury in internal organs through its anti-inflammatory activity. We aimed to investigate the neuroprotective effects of UTI on learning and memory of rats after cerebral ischemia-reperfusion injury. Rats ...
