The effect of hippocampal kindling on neuronal and glial marker proteins was studied in the rat by immunochemical methods. In hippocampus, pyriform cortex and amygdala there was an increase in glial fibrillary acidic protein (GFAP), indicating reactive gliosis, and an increase in the glycolytic enzyme NSE, suggesting increased anaerobic metabolism. Neuronal(More)
Norepinephrine-rich cell suspensions, prepared from the locus coeruleus region of rat fetuses, were grafted bilaterally into the hippocampus of rats made hypersensitive to hippocampal kindling by a neurotoxic lesion of the central catecholamine system. The animals with grafts showed a marked suppression of the onset and progression of kindling-induced(More)
Hippocampal kindling was investigated in rats with a 6-hydroxydopamine-induced lesion of the forebrain catecholamine system after implantation of neural tissue from the fetal locus coeruleus region either bilaterally into the amygdala-piriform cortex (i.e., distant to the kindling site) or unilaterally into the hippocampus (close to the kindling site).(More)
Experimental allergic encephalomyelitis (EAE) was induced in young male Lewis rats. Blood-brain barrier permeability to radiotracers of different molecular sizes was studied at intervals after induction using a tissue sampling technique. The results were correlated to the clinical picture and to the histological appearance of the central nervous system.(More)
The ethanol withdrawal syndrome in man and animals is characterized by signs of CNS hyperactivity although a direct measurement of a physiological variable reflecting this CNS hyperactivity has never been performed in untreated man or in animals. We induced ethanol dependence in the rat by means of intragastric intubation with a 20% w/v ethanol solution,(More)
As neuropeptides may play a role in the electrical kindling model of epileptogenesis, hippocampal somatostatin, Met-enkephalin and cholecystokinin were studied by immunocytochemistry in rats 24 h following full hippocampal kindling (three stage 5 seizures). As control animals we used sham-kindled rats, unoperated rats and rats subjected to a single(More)

Cerebral blood flow (CBF) autoregulation was studied in renal hypertensive rats receiving chronic antihypertensive treatment. Young Wistar Kyoto rats (WKY) were made hypertensive by the Loomis procedure i.e. partial infarction of one kidney with contralateral nephrectomy. Systolic tail blood pressure was measured at 2-week intervals throughout the study.(More)
The cerebrovascular effects of graded, controlled dihydralazine-induced hypotension were studied in rats with renal hypertension (RHR) and spontaneous hypertension (SHR). Repeated measurements of cerebral blood flow (CBF) were made using the intraarterial 133Xenon injection technique in anaesthetised normocapnic animals. Dihydralazine was administered in(More)
