The main alterations in the cadmium treated group were edema, filament cell proliferation, lamellar cell hyperplasia, lamellar fusion, epithelial lifting and aneurysm. These changes occurred predominantly in the 96 h treatment. In the combination of cadmium and ascorbic acid treated group, they showed similar alterations as those observed in the cadmium treated alone group but they were less severe. © 2007 Academic Journals.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS10.3923/ijzr.2007.77.85
