Investigation of Some Metabolic Responses in Mammals (Rattus norvegicus var. albinos) Exposed to Copper Oxide Nanoparticles
Abstract
In this study, different doses (control (0), 0.5, 5,
50 mg/kg b.w./day) of CuO nanoparticle (NP) were administered to female rats
via oral gavage for 14 days. Following
the exposures, the activities of ATPases in the kidney, brain and small
intestine and activity of acetylcholinesterase (AChE) in the brain were
measured. Levels of different glutathione forms (total GSH, rGSH, GGSG) and
TBARS (thiobarbituric acid reactive substances) were also measured in the liver
of rats. The accumulation of CuO NPs in
the tissues were demonstrated following capture of tissue images by a
transmission electron microscope (TEM). Data demonstrated that activity of AChE
in the brain decreased significantly (P<0.05). ATPase activity in the brain
and small intestine did not change significantly (P>0.05), though there were
significant decreases (P<0.05) in ATPase activity in the kidney. Levels of
glutathione forms did not change significantly, except the highest dose.
Similarly, levels of TBARS increased significantly (P<0.05) at the highest
dose. TEM images showed that CuO NPs were able to accumulate in the tissues,
emphasizing occurred alterations in enzymatic and non-enzymatic biomarkers were
due to CuO NP accumulation in the tissues.
