Implication

Animal experiment demonstrates that chronic D-galactose exposure induces septohippocampal cholinergic degeneration in rats, highlighting its utility as a model for neurodegeneration.

Key Points

Investigate whether memory impairment in a D-galactose-induced oxidative stress model is linked to cholinergic septohippocampal degeneration.
Administered chronic systemic injections of D-galactose to rats over a 6-week period.
Assessed spatial learning and memory deficits using the Morris water maze test.
Evaluated neurodegeneration using anti-choline acetyltransferase immunohistochemistry and ultrastructural synaptic analysis of the hippocampus and basal forebrain.
D-galactose-treated rats exhibited notable impairments in spatial learning and memory performance.
Immunohistochemistry demonstrated severe loss of cholinergic terminals in the hippocampus, along with mild neuronal atrophy and cell loss in the medial septum and vertical limb of the diagonal band of Broca.
Ultrastructural examination confirmed extensive synaptic degeneration within hippocampal tissue.
