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.engMahidol UniversityRed-tailed tinfoil barb Puntius altusascorbic acid cadmiumlight microscope scanning electron microscopeArticleScience Alert
