Megjegyzések:	Aluminum (Al) excess and hypercholesterinaemia are established risks of Alzheimer's disease (AD). The aim of this study was to establish an AD-resembling hypercholesterinaemic animal model?with the involvement of 8 week and 48 week-old Fischer-344 rats?by Al administration for the safe and rapid verification of ? -amyloid-targeted positron emission tomography (PET) radiopharmaceuticals. Measurement of lipid parameters and ? -amyloid?affine [11C]C-Pittsburgh Compound B ([11C]C-PIB) PET examinations were performed. Compared with the control, the significantly elevated cholesterol and LDL levels of the rats receiving the cholesterol-rich diet support the development of hypercholesterinaemia (p?0.01). In the older cohort, a notably increased age-related radiopharmaceutical accumulation was registered compared to in the young (p?0.05; p?0.01). A monotherapy-induced slight elevation of mean standardised uptake values (SUVmean) was statistically not significant; however, adult rats administered a combined diet expressed remarkable SUVmean increment compared to the adult control (SUVmean: from 0.78?0.16 to 1.99?0.28). One and two months after restoration to normal diet, the cerebral [11C]C-PIB accumulation of AD-mimicking animals decreased by half and a third, respectively, to the baseline value. The proposed in vivo Al-induced AD-resembling animal system seems to be adequate for the understanding of AD neuropathology and future drug testing and radiopharmaceutical development.
