Aluminum in the organs and diet of ageing C57BL/6J mice.
Total aluminum concentrations increased with ageing in the liver and kidney of male C57BL/6J mice, remained unchanged in brain and heart, and decreased with ageing in femur and lung for mice ranging in age from 56 to 1186 days. Ligating one kidney did not significantly increase aluminum concentrations in the various organs. Feeding 1 X 10(-2) M aluminum chloride (270 ppm Al) in the drinking water beginning at 604 days of age decreased the average life span by 6.7%. We conclude that very little aluminum accumulation occurs with ageing in the organs tested in this study, in spite of a high dietary intake. Other organs might show a change. Only one aluminum concentration was used in this study which accelerated the rate of ageing as indicated by a change in the survival curve. The effect of higher or lower aluminum concentrations remains to be seen.
