OBJECTIVE
The neurotoxic effects of cyclosporine therapy are well known but poorly understood. Imaging studies typically show subcortical edema predominantly affecting the posterior regions of the brain. We sought to determine the causes for these findings by comparing radiographic data with various
1. The aim of the present study was to reveal the effect of transient forebrain ischemia on the regional and temporal changes in the permeability of the blood-brain barrier (BBB) permeability for sodium fluorescein (MW: 376 Da) and Evan's blue-labeled albumin (MW: 67 kDa) in stroke-prone
Disruption of the blood-brain barrier may play a major role in the pathogenesis of hypertensive encephalopathy. In this study we determined whether sympathetic nerves to cerebral vessels protect the blood-brain barrier during chronic hypertension. We removed the cervical sympathetic ganglion on one
The purpose of the study was to explore the effect of YangXue QingNao Wan (YXQNW), a compound Chinese medicine, on cerebrovascular hyperpermeability, neuronal injury, and related mechanisms in spontaneously hypertensive rat (SHR).Fourteen-week-old male SHR The most common acute glomerulonephritis in children is poststreptococcal glomerulonephritis (PSGN) usually occurring between 3 and 12 years old. Hypertension and gross hematuria are common presenting symptoms. Most PSGN patients do not experience complications, but rapidly progressive
Disruption of the blood-brain barrier (BBB) during acute hypertension may contribute to hypertensive encephalopathy. In this study we tested the hypothesis that, in chronic hypertension, vascular changes might influence the susceptibility of the BBB to disruption. Spontaneously hypertensive rats
Hypertensive encephalopathy occurs when acute changes in blood pressure cause breakdown of the blood-brain barrier (BBB). Angiotensin II (Ang II) plays a role in this pathophysiology. We determined whether Ang II directly regulates endothelial cell function at the BBB. In BBB microvessel endothelial
After the synthesis of epoetins alpha and -beta, a third molecule of recombinant human erythropoietin (rHuEPO) was synthesized and was named epoetin-omega. The molecule of epoetin-omega is a sialoglycoprotein with smaller amounts of O-bound sugars, less acidic and with different hydrophylity than
This study was undertaken to: (i) determine the prevalence, pattern and outcome of systemic complications of acute glomerulonephritis (AGN), and (ii) evaluate some clinicolaboratory features of the disease in Nigerian children. Clinical and laboratory records of consecutive cases of AGN seen over a
