Delayed neuronal recovery and neuronal death in rat hippocampus following severe cerebral ischemia: possible relationship to abnormalities in neuronal processes.
Mechanisms involved in the postischemic delay in neuronal recovery or death in rat hippocampus were evaluated by light and electron microscopy at 3, 15, 30, and 120 min and 24, 36, 48, and 72 h following severe cerebral ischemia that was produced by permanent occlusion of the vertebral arteries and 30-min occlusion of the common carotid arteries. During the early postischemic period, neurons in...
متن کاملDelayed cerebral ischemia following arteriography.
Cerebral ischemic events associated with arteriography are usually attributed to catheter-induced emboli. We present three patients with cerebral ischemia occurring 6 to 48 hours post-arteriography. We suspected that alternate pathogenic mechanisms were in effect. To evaluate the possibility that sustained platelet activation occurs in association with arteriography, we measured the platelet-sp...
متن کاملP51: Anti-Inflammatory Curcumin Effect on Neuronal Number in the CA1 Area Following Global Cerebral Ischemia
Global cerebral ischemia (GCI) leads to inflammation and neuronal death in CA1. Curcumin with neuroprotective and anti-inflammatory properties is a potential candidate for suppressing cell death. The aim of this study was to determine the effects of curcumin on neuronal number in the CA1 area following GCI. 28 Sprague-Dawley male rats were randomly assigned into four groups including sham, cont...
متن کاملInvolvement of MMPs in delayed neuronal death after global ischemia.
Spatial and temporal relations between metalloproteinase (MMP-2 and MMP-9) activation and laminin degradation in gerbil hippocampus after transient cerebral ischemia has been studied. Activity of MMPs was determined by gelatin zymography in homogenates from dorsal (DP, an equivalent of CA1 sector) and abdominal (AbP, containing CA2-4 and gyrus dentatus) parts of hippocampus. A significant activ...
متن کاملNeuroprotective Effects of Chrysin Mediated by Estrogenic Receptors Following Cerebral Ischemia and Reperfusion in Male Rats
Introduction: Ischemic stroke is one of the leading causes of morbidity and mortality worldwide. Neuroprotective strategies were reported to attenuate cognitive deficits after ischemic incidents. Here we studied the neuroprotective potential of chrysin in a rat model of cerebral Ischemia/Reperfusion (I/R) in the presence or absence of Estrogen Receptors (ERs). Methods: Adult male Wistar rats w...
