ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of exposure to aluminum (Al) on Zn, Fe, Cu and Ca contents in hippocampus of rats.</p><p><b>METHODS</b>AlCl(3).6H(2)O was administered orally through diet (8% of body weight) to SD rats at doses of 0 (A), 11.2 (B), 55.9 (C), 111.9 (D) mg Al(3+)/kg BW for successive 90 days. Then Al, Zn, Fe, Cu and Ca contents in hippocampi of rats were determined by atomic absorption spectrophotometry.</p><p><b>RESULTS</b>After oral exposure to Al, the Al content in hippocampus of rat increased significantly with a remarkable dose-effect relationship (r = 0.731, P < 0.001), The Zn, Fe, Ca and Cu contents in these four groups are as follows Group A (18.29 +/- 2.48, 24.86 +/- 1.97, 48.69 +/- 22.08, 4.53 +/- 0.99) mg/g, Group B (17.22 +/- 2.06, 27.54 +/- 2.87, 42.79 +/- 14.42, 4.06 +/- 0.41) mg/g, Group C (14.46 +/- 1.90, 20.18 +/- 2.79, 29.95 +/- 7.33, 3.98 +/- 0.25) mg/g, Group D (15.85 +/- 2.54, 20.96 +/- 2.83, 36.14 +/- 12.66, 4.53 +/- 0.58) mg/g. Compared with the control group A, the Zn and Fe contents in group B and group C decreased significantly (P < 0.05), and the Ca content in group C also decreased significantly.</p><p><b>CONCLUSION</b>Oral exposure to Al may result in accumulation of Al in hippocampus of brain and thus affect some essential elements (Zn, Fe, Cu and Ca) contents in the hippocampus at different degrees.</p>
