    Abstract:
    The present study assesses the effect of unilateral lesions of the nucleus basalis magnocellularis (NBM) and of treatment with L-alpha-glyceryl phosphorylcholine (GFC, choline alfoscerate) on the acetylcholine-synthesizing (choline acetyltransferase (ChAT)), and acetylcholine-degradating (acetylcholinesterase (AChE)) enzymes in the rat fronto-parietal cortex ipsilateral to the lesion. Ibotenic acid injections in the right NBM area caused a significant decrease of both ChAT and AChE activities as well as of histochemically reactive stores of AChE in the right fronto-parietal cortex. Treatment with GFC restored in part the loss of ChAT and AChE activities. Moreover, AChE reactivity is restored in the fronto-parietal cortex of NBM-lesioned rats treated with GFC. GFC is a precursor in the biosynthesis of brain phospholipids which increases the bioavailability of acetylcholine in the nervous tissue. The possible relevance of the restoration of the marker enzymes of cholinergic neurotransmission by GFC in an animal model of cholinergic hypofunction is considered.
