Neuroprotective effect of vasopressin analogues, arginine Vasopressin (AVP) and lysine Vasopressin (LVP) was evaluated against MgCl2 induced cerebral ischemia model. AVP significantly prevented (P < 0.01) MgCl2 (1M) induced cerebral ischemia as compared to lysine Vasopressin (LVP) which was less effective (P < 0.05). Pretreatment with PI-3 kinase inhibitors, Wortmannin and LY-294002 (50 microg/...

Neurodegenerative processes of the central nervous system are an important socially significant problem modern society. They cause many diseases, such as Alzheimer's disease and cerebral ischemia, which significantly reduce quality human life can lead to disability or death. The aim this study was synthesize novel 6,7-dimethoxyquinazolin-4(3H)-one derivatives with remains neuroactive amino acid...

BACKGROUND AND PURPOSE Angiotensin-converting enzyme inhibitors have been shown to protect against stroke in hypertensive rats and to improve neurological outcome after cerebral ischemia in normotensive rats. The present study was designated to test the hypothesis that blockade of brain AT(1) receptors improves the recovery from focal cerebral ischemia and reduces expression of AP-1 transcripti...

Information on the effects of injury on neovascularization in the immature brain is limited. We investigated the effects of ischemia on cerebral cortex neovascularization after the exposure of fetuses to 30 minutes of cerebral ischemia followed by 48 hours of reperfusion (I/R-48), 30 minutes of cerebral ischemia followed by 72 hours of reperfusion (I/R-72), or sham control treatment (Non-I/R). ...

OBJECTIVE Bumetanide has been reported to attenuate ischemia-evoked cerebral edema. However, whether bumetanide can protect cerebral ischemia-reperfusion injury (IRI) in vivo is unclear. In the present study, we aim to determine whether intravenously injection bumetanide can attenuate cerebral IRI and if its protection effect might be related to the modification of cerebral NKCC1 and KCC2 prote...

treatment and post-treatment with alpha-tocopherol attenuates hippocampal neuronal damage in experimental cerebral hypoperfusion. and antioxidant enzyme levels during cerebral hypoperfusion in rats. Brain Res. supplemented air inhalation reduces changes of prooxidant enzyme and gap junction protein levels after transient global cerebral ischemia in the rat hippocampus. Brain T cells in acute ex...

Stroke is a major cause of death and long-term disability. Chlorogenic acid phenolic compound with potent neuroprotective effect. γ-enolase phosphopyruvate hydratase found in mature neurons plays an important role the neuronal survival. This study investigated whether chlorogenic regulates expression during cerebral ischemia. Middle artery occlusion (MCAO) was performed to indcue Adult male rat...

background: hyperthyroidism as a risk factor for stroke is not conclusive. there are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. this study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. methods: two groups of hyperthyroid (ht) and control euthyroid rats of equal numbers ...

The aim of this study was to explore the effect of gastrodin on the level of amino acids in the striatum in the rats of cerebral ischemia-reperfusion injury. 30 male SD rats were randomly divided into 3 groups: the group of pseudo-operation (normal control group, NC group), the group of cerebral ischemia-reperfusion injury (CIRI group), and the group of cerebral ischemia-reperfusion injury trea...

The mechanisms of myocardial dysfunction and calcium handling disturbance underlying cerebral ischemia remain obscure. Here we for the first time report that acute cerebral ischemia significantly increased left ventricular end diastolic pressure (LVEDP), but decreased +dP/dt, -dP/dt, and left ventricular systolic pressure (LVSP). Significant increase in either the resting or KCl-induced [Ca2+](...
