2 nonenal/脳卒中

4-Hydroxy-2-nonenal (4-HNE), one of the major biologically active aldehydes formed during inflammation and oxidative stress, has been implicated in a number of cardiovascular and pulmonary disorders. 4-HNE has been shown to increase vascular endothelial permeability; however, the underlying

Stroke is a major neurologic disorder and a leading cause of death in the world. We compared neuroprotective effects of single or combination therapy of amlodipine (AM) and atorvastatin (AT) in such a metabolic syndrome model Zucker rat after 90 min of transient middle cerebral artery occlusion

Background: During an acute stroke, reactive oxygen species are overproduced and the endogenous antioxidative defense systems are disrupted. Therefore, antioxidative therapy can be a promising scheme to reduce the severity of stroke. Neumentix is a novel

The vascular protective effects of placebo, candesartan (1 mg kg(-1) per day) monotherapy, candesartan (1 mg kg(-1) per day) and amlodipine (1 mg kg(-1) per day) combination therapy, and candesartan (1 mg kg(-1) per day) and hydrochlorothiazide (HCTZ) (10 mg kg(-1) per day) combination therapy for 2

Previously, we reported that reactive oxygen species and signaling molecules of angiotensin II produced lipid peroxides, degenerated proteins, and injured DNA after cerebral ischemia in normotensive Wistar rats. Here, we investigated the long-term effect of the angiotensin II type I receptor blocker

BACKGROUND Oxidative stress and inflammation are important aggravating factors in acute ischemic stroke. METHODS In the present study, the neuroprotective effects of a novel antioxidant mixture Twendee X containing multiple antioxidative ingredients, such as coenzyme Q10, ascorbic acid, and cystine,

Aldehyde dehydrogenase 2 (ALDH2) is a mitochondrial enzyme that metabolizes ethanol and toxic aldehydes such as 4-hydroxy-2-nonenal (4-HNE). Using an unbiased proteomic search, we identified ALDH2 deficiency in stroke-prone spontaneously hypertensive rats (SHR-SP) as compared with spontaneously

Cilnidipine is an L- and N-type calcium channel blocker (CCB), and amlodipine is an L-type CCB. Valsartan (10 mg kg(-1)), valsartan (10 mg kg(-1)) and amlodipine (1 mg kg(-1)), and valsartan (10 mg kg(-1)) and cilnidipine (1 mg kg(-1)) were administered once daily for 2 weeks to stroke-prone,

Aldehyde dehydrogenase 2 (ALDH2) is a new therapeutic target in the central nervous system. However, the association between ALDH2 and brain edema following ischemic stroke (IS) remains unclear. The present study was investigated to whether active ALDH2 can attenuate brain edema by using a rat model

Local axonal degeneration is a common pathological feature of peripheral neuropathies and neurodegenerative disorders of the central nervous system, including Alzheimer's disease, Parkinson's disease, and stroke; however, the underlying molecular mechanism is not known. Here, we analyzed the gracile

Angiotensin II receptor blockers (ARBs) vary in their binding affinities to angiotensin II type 1 (AT(1)) receptors in in vitro experiments. We compared a high-affinity ARB, olmesartan, and a low-affinity ARB, valsartan, in terms of their vascular protective effects in stroke-prone spontaneously

To assess whether azelnidipine (AZN) exerts renoprotective effects, 20-week-old adult male stroke-prone spontaneously hypertensive rats (SHRsp) were treated with AZN 10 mg/kg/d (n=6), olmesartan (OLM) 3 mg/kg/d (n=4), hydralazine (HYD) 20 mg/kg/d (n=3), or water (control; n=5). Each test agent was

BACKGROUND Heavy ethanol consumption is widely accepted as a risk for ischemic stroke. The molecular mechanisms of ethanol-induced brain injury have not been fully understood. OBJECTIVE This study aims to find out the mechanism of the ischemic cerebral injury. METHODS We used Sprague-Dawley rats

BACKGROUND Hyperbaric oxygenation (HBO) after focal cerebral ischemia reduces infarct size and improves outcome when applied early after stroke. Here, we evaluated effects of HBO on permanent focal cerebral ischemia and applied magnetic resonance imaging (MRI) monitoring to study lesion

Thrombolytic therapy with recombinant tissue plasminogen activator (rtPA) after ischemic stroke is effective. However, rtPA potentiates neuronal damage, and interactions between rtPA and thrombolysis products (TLP) have been reported to play a role in this. In the present study we investigated the
