1. We have previously described an increased sensitivity to inhibition by nifedipine of noradrenaline-induced contractures of blood vessels in hypertension. In this study we have investigated whether changes in blood pressure (BP) change the sensitivity to nifedipine and K+ of aortic rings from
The brain is an integrated network of multiple variables that when compromised create a diseased state. The neuropathology of temporal lobe epilepsy (TLE), stroke, and traumatic brain injury (TBI) demonstrate both similarity and complexity that reflects this integrated variability; TLE with its live
OBJECTIVE
Hyperglycemia following acute stroke is strongly associated with subsequent mortality and impaired neurological recovery, but it is unknown whether maintenance of euglycemia in the acute phase improves prognosis. Furthermore, the safety of such intervention is not established.
METHODS
In
Insulin is neuroprotective in animal stroke models but its effects in acute stroke in humans are unknown. The Glucose Insulin in Stroke Trial (GIST-UK) is a randomised controlled trial investigating the benefits of maintaining euglycaemia in hyperglycaemic patients with acute stroke. Data are
BACKGROUND
Dietary potassium supplementation decreases blood pressure and prevents strokes in humans, and prevents strokes and renal damage in Dahl salt-sensitive (DSS) rats.
OBJECTIVE
To study the effects of various concentrations of dietary potassium chloride (KCl) on the hemodynamics of Dahl
Several types of antihypertensive agents, including calcium antagonists, have been reported to prevent stroke and prolong survival in stroke-prone spontaneously hypertensive rats (SHR-SP). We investigated whether mibefradil, a new calcium antagonist acting selectively at the level of T-type calcium
High sodium chloride (NaCl) intake is associated with health risks. NaCl may be replaced by potassium chloride (KCl) to decrease sodium intake. However, increased potassium may also have negative health effects. We conducted a benefit and risk assessment of increasing potassium by ratios of 30:70,
The effects of central venous bolus injections of potassium chloride (KCl) on arterial potassium concentration were studied in patients undergoing cardiopulmonary bypass. Ten subjects were studied, and each received a rapid bolus injection of KCl, 33 microEq/kg, both before and after cardiopulmonary
OBJECTIVE
To investigate in young salt-loaded stroke-prone spontaneously hypertensive rats (SHR-SP) the effects of a long-term administration of the angiotensin II AT1 receptor antagonist losartan [1 mg/kg (L1) and 10 mg/kg (L10) per day, from 5 to 20 weeks of age] on the structural and functional
OBJECTIVE
(1) To demonstrate the importance of nutrition, especially sodium restriction and increased potassium and protein intakes, in the prevention of hypertension and stroke in a pilot study involving senior citizens. (2) To design a population-based intervention in the Shimane Prefecture of
Spasticity obstructs motor function recovery post-stroke, and has been reported to occur in spinal cord injury and electrophysiological studies. The purpose of the present study was to assess spinal cord circuit spasticity in post-stroke mice. At 3, 7, 21, and 42 d after photothrombotic ischemic
Post-stroke depression (PSD) is a common and serious complication that affecting one third of stroke patients for poor quality of life, high mortality, high recurrent rate, and slow recovery. Recent studies showed that serum interleukin-18 (IL-18) level is a biomarker for patients with PSD. However,
Therapeutic agents that restore the inhibitory actions of γ-amino butyric acid (GABA) by modulating intracellular chloride concentrations will provide novel avenues to treat stroke, chronic pain, epilepsy, autism, and neurodegenerative and cognitive disorders. During development, upregulation of the
The prevalence of occlusive stroke is inversely correlated with potassium intake. We explored the hypothesis that a high potassium intake attenuates platelet reactivity, as expressed in ADP-evoked platelet aggregation. We studied healthy men (n=31) and women (n=42), blacks (n=33) and whites (n=40).
Twelve male mongrel dogs were used for this study; six were untreated (control) and six were given intravenous furosemide (1 mg/kg) daily for seven consecutive days before each study. Each animal received intravenous KCl 0.8, 1.6 or 3.2 mMol/kg/hr for one hour, but only one dose for each study and
