a b s t r a c t introduction: even today there is no effective drug therapy to prevent neuronal loss after brain stroke. in the present study we studied the effect of mitochondrial katp channel regulators on neuronal ultrastructure after ischemia reperfusion in the rat. materials & methods: rats temporarily subjected to four vessels occlusion for 15 minutes followed by 24 hours reperfusion with...

Several lines of evidence have indicated that many nuclei in the brain including preoptic nucleus, AV3V, subfornical organ, septal area and lateral hypothalamus are the targets of efferents from chemo-sensitive and pressure-sensitive systems. These areas may concern with regulation of fluid homeostasis. In the present study, intracerebroventricular injections were carried out in all experiments...

Introduction: Repetitive cortical spreading depression (CSD) can lead to cell death in immature brain tissue. Caspases are involved in neuronal cell death in several CSD-related neurological disorders. Yet, whether repetitive CSD itself can induce caspase activation in adult or juvenile tissue remains unknown. Inducing repetitive CSD in somatosensory cortices of juvenile and adult rats in vivo,...

1. Acetoacetate or dl-beta-hydroxybutyrate increases the rate of oxygen consumption to a smaller extent than that brought about by glucose or pyruvate in adult rat brain-cortex slices but to the same extent as that in infant rat brain-cortex slices. 2. The rate of (14)CO(2) evolution from [1-(14)C]glucose considerably exceeds that from [6-(14)C]glucose in respiring infant rat brain-cortex slice...

Objective(s) Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the present study, we aimed to investigate the gastroprotective potential of either p...

Stroke is one of the leading causes mortality and disability throughout world. Recently, antioxidant therapies were attempted to reduce apoptotic cell death in cerebral ischemia animal model. To study neuroprotective properties polyphenol derived from fungal endophyte analyzed on experimental Albino rat. Polyphenols producing endophytic fungi was initially isolated seeds Moringa oleifera Lam. T...
