Effect of a Combination of Citric Acid and Selenium Nanoparticles on Male Rats Nephrotoxicity Caused by Carbon Tetrachloride

Abstract

Background: To investigate the therapeutic effects of a combination of citric acid and Se-NPs against carbon tetrachloride (CCl4)-induced renal damage in rats. Methods: Twenty-four rats were divided into three groups (n = 8 each). Group 1 (control) received the vehicle, while Group 2 received a single dose of 1 ml/kg CCl4 in liquid paraffin (1:1 volume) via intraperitoneal injection. Group 3 was administered a single dose of 1 ml/kg CCl4 in liquid paraffin and then treated twice a week for three weeks with a dose of 2.5 mg/kg Se-NPs. One-way ANOVA and Tukey’s method were used to compare the overall effects of each treatment. Result: CCL4 elevated MDA levels and decreased GSH levels in group 2 animals compared with those in the control group. Se-NPs significantly restored the oxidative stability in group 3. We found that CCL4 significantly increased its effect on renal function, whereas Se-NPs restored the renal structure affected by CCL4. As a result, Se-NPs can potentially reduce the markers of renal injury caused by CCl4, while also restoring oxidative stability and renal structure and function.
