AbstractIt is well known that lanthanides have come into extensive and rapid use in a number of fields. As a result, more and more lanthanides are getting into the environment and food chains. However, the distributions of lanthanides in brain are not yet very clear. In this study, adult Sprague-Dawley male rats were intravenously injected with 0.5 ml of (YbCl3)-Yb-169 solution (containing 10 mug Yb). The brains were perfused with saline to minimize the blood influence. The radioactivities of Yb-169 in the five brain regions (hypothalamus, cerebellum, hippocampus, corpus striatum and cerebral cortex) were counted. The results suggested that Yb did enter into the brain. Though only about 0.005% of the given dose was accumulated in the brain, Yb seemed to remain in the brain for long time. The highest specific activities were observed in the hypothalamus, hippocampus and cerebellum. (C) 2004 Elsevier Ireland Ltd. All rights reserved.
