The effects of nerve growth factor beta (beta-NGF) and ganglioside GM1 on forebrain cholinergic neurons were examined in vivo and in vitro. Following unilateral decortication of rats, GM1 (5 mg/kg per day) administered intracerebroventricularly could protect forebrain cholinergic neurons of the nucleus basalis magnocellularis from retrograde degeneration in a manner comparable to beta-NGF. Admi...
Amyloid-beta (Abeta) is toxic to neurons and such toxicity is - at least in part - mediated via the NMDA receptor. Calpain, a calcium dependent cystein protease, is part of the NMDA receptor-induced neurodegeneration pathway, and we previously reported that inhibition of calpain prevents excitotoxic lesions of the cholinergic nucleus basalis magnocellularis of Meynert. The present study reveals...
Introduvtion: Alzheimer's disease is one of the most common neurodegenerative diseases in the brain. The aim of this study was to evaluate the effect of lovastatin and folic acid on cognitive deficit by induced lesion in nucleus basalis magnocellularis Methods: In this experimental study, 56 male Wistar rats were randomly divided into 8 groups: (7 rat in each group): control(intact), Nucleus b...
Rats with electrolytic lesions of the nucleus basalis magnocellularis were compared to sham-lesioned rats in the retention of a continuously reinforced lever-pressing response and in the acquisition and reversal of a visual discrimination task. The muscarinic agonist pilocarpine, in conjunction with the peripheral muscarinic antagonist methyl-scopolamine, was administered in three doses to subs...
The nucleus basalis magnocellularis (nbm)-lesioned rat is considered to be a model of the cholinergic dysfunction observed in the cerebral cortices of Alzheimer's disease patients. The cholinergic markers, acetylcholine release and choline acetyltransferase activity, were decreased in the cerebral cortex of the nbm-lesioned rat. Kangenkaryu (KAN), a Chinese traditional medicine, is a typical pr...
