Chronic treatment with fluoxetine (FLX) is required for its antidepressant effects, but the role of serotonin (5-HT) axonal plasticity in FLX action is unknown. To address this, we examined mice with a stroke in the left medial prefrontal cortex (mPFC) resulting in persistent anxiety-like and
Present study was undertaken to elucidate the effects of E-643, on blood pressure, urinary electrolyte (U-Na, U-K) and catecholamines excretion rates in stroke-prone spontaneously hypertensive rats (SHRSP). An attempt was also made to clarify the effects of E-643 on plasma catecholamine
Although mammalian ventricle is richly supplied with adrenergic nerves, endogenous norepinephrine is not essential to the intrinsic contractility of the normal heart. However, it is not clear whether acute changes in cardiac norepinephrine could alter heart function in genetically hypertensive rats.
OBJECTIVE
Evidence is now available about the association between chronic kidney disease (CKD) and stroke. However, less is known about the underlying mechanisms, and there is currently no reliable marker for identifying stroke-prone high-risk patients among CKD patients.
METHODS
A total of 514
Twenty CT proven patients of thrombotic stroke who were non-diabetic, non-hypertensive and non-hyperlipidemic were evaluated in acute phase (within 7 days of onset of neurological deficit) for platelet count and spontaneous platelet norepinephrine (NE) efflux, measured as the fraction (of initial
The norepinephrine (NE) concentration of cardiac ventricles was determined by radioenzymatic assay in normotensive Wistar Kyoto rats (WKY), spontaneously hypertensive rats (SHR), and stroke-prone rats (SPR) at 3-6, 14-19, and over 31 weeks of age. There was no difference between strains prior to
L-threo-3, 4-dihydroxyphenylserine (L-DOPS) is a precursor of norepinephrine. We reported that administration of L-DOPS to rats with ablation of the right sensorimotor cortex results in functional recovery from deficits in beam-walking performance. We al so reported that improvement in Fugl-Meyer
The effect of taurine on vascular reactivity was investigated in the mesenteric artery of Wistar Kyoto (WKY), and stroke-prone spontaneously hypertensive rats (SHRSP). Administration of taurine significantly decreased blood pressure of SHRSP but not WKY. The mesenteric artery of taurine-treated
The feasibility and safety of induced arterial hypertension (10 to 20% of the initial value) in the acute phase of ischemic stroke were retrospectively evaluated in 34 patients treated with norepinephrine (NE) for a median of 26 hours. Maximal variability of systolic blood pressure during NE
The content of norepinephrine (NE) and epinephrine (E) in the brain of spontaneously hypertensive rats has proved abnormal, but the cause remained unknown. It was shown in the recent work that NE content in pons, posterior hypothalamus, nucleus caudatus and E concentration in medulla oblongata,
Cardiac arrhythmias, myocardial necrosis and ECG abnormalities in stroke may result from abnormally high levels of sympathetic activity. To examine this possibility, plasma norepinephrine, epinephrine and dopamine were measured in 74 patients with cerebral infarction, 18 with transient ischemic
The present study was undertaken to elucidate the effect of pure tone stimulation on sympathetic nerve activity in stroke-prone spontaneously hypertensive rats (SHRSP). SHRSP were exposed to a pure tone stimulation of 4 KHz at 60 dB SPL tone burst which was interrupted at a frequency of one second
The purpose of this study is to develop a computer model of oscillatory contractions in isolated arteries from the tails of spontaneously hypertensive, stroke-prone rats (SHRSP). The computer simulation incorporates biologic data from experiments and mathematic expressions derived from an electric
Stroke is a multifactorial disease and a consequence of morbidities of diabetes, obesity, hypertension, and heart diseases. Leptin is a major adipokine that regulates weight balance and energy homeostasis, the level of which has been considered as an indicator of acute ischemic stroke. In the
