Sub-Acute Oral Toxicity of Zinc Oxide Nanoparticles in Male Rats

ZnO-NPs suspended in distilled water were administered to Wistar rats at dose of 10 mg/ kg body weight through oral gavage for 5 consecutive days. The mean body weight gain in rats given ZnO-NPs was similar to this of control group, so no significant differences in the relative organs weight were observed between the ZnO-NPs treated-rats and control. Moreover, ZnO-NPs-exposed rats showed normal values for the complete blood count test. However, biochemical assays showed that sub-acute exposure to ZnO-NPs induced a marked increase of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Read more...
