Study investigated the effect of oral administration of gold-silver nanoparticleson rat biochemical parameters and tissue morphology. Wistar rats weighingapproximately 180±7 g were randomly assigned into four groups. Animals in thecontrol group received distilled water once daily for 30 days while, those in thetreatment groups were administered 10, 50 and 100 mg kgG1 b.wt. gold-silvernanoparticles. The rats were sacrificed under slight anesthesia, 24 h after the lasttreatments. Blood and vital organs including the heart, kidney and liver werecollected and prepared for biochemical and histopathological determinations.Exposure to Ag/Au nanoparticles altered the rat serum lipid profile; lowering theHDL-C while raising the atherogenic index. Exposure of Ag/Au nanoparticles inrats caused significant alteration to the levels of serum albumin, total protein,bilirubin, urea and creatinine. The activities of alanine transaminase, aspartatetransaminase and alkaline phosphatase in rat serum and tissues were alsosignificantly altered by Ag/Au nanoparticles exposure. The histopathologicalexamination revealed inflammation and cellular degeneration caused by exposureto the Ag/Au nanoparticles. We show evidence that Ag/Au nanoparticles elevatedatherogenic index, as well as caused biochemical and morphological alterations,reminiscent of cellular injury
