Unexpected Lack of Deleterious Effects of Uranium on Physiological Systems following a Chronic Oral Intake in Adult Rat

Figure 4

Histological alterations of intestinal, renal, and hepatic sections in rats receiving uranium at 120 mg/L in drinking water for 9 months. Microphotographs of rat tissues were obtained from control (NC: noncontaminated) and contaminated rat (120 mg/L uranium in drinking water). Sections were stained with hematoxylin-eosin-saffron. ((a), (b)) Intestinal longitudinal sections of rat ileum. ((c)–(f)) Histological sections of renal cortex. ((g)–(j)) Liver sections.
