superoxide dismutase/脳卒中

Although angiotensin II type 1 (AT1) receptor antagonists and angiotensin-converting enzyme (ACE) inhibitors are known to reduce both reactive oxygen species (ROS) generated by activated NAD(P)H oxidase and vascular remodeling in hypertension, the effects of AT1 receptor antagonists or ACE

Oxidative stress has been implicated in the pathogenesis of hypertension. The aim of the present study was to determine whether increased generation of vascular superoxide anion (*O2-) contributes to blood pressure elevation by influencing vascular function and structure in severely hypertensive

The manganese-dependent superoxide dismutase (MnSOD) Ala16Val single nucleotide polymorphism (SNP) has shown to be associated to risk factors of vascular diseases. Brain-Derived Neurotrophic Factor (BDNF) plays an essential role in the plasticity and neuronal regeneration of the brain after vascular

OBJECTIVE The aim of this study was to determine whether antioxidant therapy could relieve hypertension and retard the progression of renal damage in advanced-stage hypertensive rats. METHODS Twenty-four-week-old spontaneously hypertensive stroke-prone rats were treated for 8 weeks with the

This study aimed to clarify the kinetics of copper-zinc (CuZn) and manganese (Mn) superoxide dismutase (SOD) activity in acute ischemic stroke victims. Using the nitrite method, we investigated sequential changes in CuZn and Mn SOD activity in the cerebrospinal fluid (CSF) of 8 patients with acute

1. Enzyme activities and contents of manganese and copper-zinc superoxide dismutase (Mn-, Cu/Zn-SOD) and oxygen free-radical scavengers were determined in the myocardium (right, left ventricle) and brain (cerebral cortex, hippocampus) of 15 and 31 week old stroke-prone spontaneously hypertensive

Background and Purpose: Oxidative stress is involved in the development of infections. However, whether oxidative stress indicators can be used as markers of stroke-associated infection (SAI) is still unclear. The purpose of this study was to test the predictive values of superoxide dismutase

A significant factor in the development of hypertension may be excessive vasoconstriction within the renal medulla. This study therefore investigated the role of superoxide dismutase (SOD) in the regulation of renal medullary and cortical blood perfusion (MBP and CBP, respectively) in both

Ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E) have antioxidant properties that could improve redox-sensitive vascular changes associated with hypertension. We determined whether vitamins C and E influence vascular function and structure in hypertension by modulating activity of NADPH

Oxidative stress in the rostral ventrolateral medulla (RVLM) increases sympathetic nervous system activity (SNA). Oral treatment with atorvastatin decreases SNA through antioxidant effects in the RVLM of stroke-prone spontaneously hypertensive rats (SHRSP). We aimed to examine whether centrally

Recent studies have suggested that the calcium antagonists have an antiatherogenic antioxidant property. The effects of the calcium antagonists on reactive oxygen species (ROS)-related enzymes, however, remain unknown. We hypothesized that the calcium antagonists inhibit oxidative stress in the

No evidence is currently provided on the involvement of uric acid (UA) and Cu/Zn Superoxide Dismutase (Cu/Zn SOD) in functional recovery of stroke patients after neurorehabilitation. For this purpose, the relationship between UA and Cu/Zn SOD plasma levels and clinical and functional outcome

Superoxide dismutase (SOD), neuron specific enolase (NSE) and lactic dehydrogenase (LDH) were measured in the serum and cerebrospinal fluid (CSF) of ischemic cerebrovascular patients, other neurological patients and in age-matched healthy controls (serum only). The levels of SOD in the CSF or serum

OBJECTIVE Manganese superoxide dismutase (MnSOD), one of the most crucial antioxidant enzymes in the central nervous system, is thought to be one of the major mechanisms by which cells counteract the injuries of reactive oxygen species after cerebral ischemia. In this study, we used a novel

Stroke is a severe and prevalent syndrome for which there is a great need for treatment, including agents to block the cascade of brain injury that occurs in the hours after the onset of ischemia. Reactive oxygen species (ROS) have been implicated in this destructive process, but antioxidant enzymes
