Chronic cerebral ischemia may accelerate clinicopathological changes in Alzheimer's disease. We have examined whether chronic cerebral hypoperfusion accelerates amyloid beta deposition in amyloid protein precursor transgenic (APP-Tg) mouse. At 5, 8, and 11 months of age, C57Bl/6J male mice overexpressing a mutant form of the human APP bearing the both Swedish (K670N/M671L) and the Indiana (V717...

BACKGROUND AND PURPOSE We tested the hypothesis that cerebral hypoperfusion after experimental global cerebral ischemia is caused by plugging of the microcirculation with activated leukocytes using in vivo microscopic observation of the behavior of leukocytes in the cortical microcirculation during the transition from postischemic hyperperfusion to hypoperfusion. METHODS Anesthetized and vent...

INTRODUCTION Chronic hypoperfusion in rats produces memory and learning impairments due to permanent occlusion of commun carotid arteries (POCCA). Molecular mechanisms leading to behavioural disorders have been poorly studied. For this reason, the aim of the present study was to characterise oxidative metabolism disorders and their implications in memory and learning impairments. METHODS Supe...

The present study investigates the effect of Withania somnifera (WS), a well-known adaptogenic agent in Indian system of Medicine, on acute cerebral reperfusion and long-term cerebral hypoperfusion in rats. Acute ischemiareperfusion (30 min occlusion of bilateral common carotid arteries followed by 45 min. reperfusion) and Long-term cerebral hypoperfusion (for 15 days) in C.F. strain rats were ...
