Summary: | Abstract
In this study, the toxic effects of aflatoxin B
2
(AFB
2
) on Swiss albino mice and the protective effects of resveratrol were investigated. Physiological (body weight, liver and kidney weight), biochemical (aspartate aminotransferase-AST, alanine transaminase-ALT, blood urea nitrogen-BUN, creatinine, malondialdehyde-MDA and glutathione-GSH) and cytogenetic parameters (micronucleus-MN in buccal epithelium, erythrocyte and leukocyte cells and chromosomal aberrations-CAs) were used to determine the toxic effects. Additionally, scavenging effects of resveratrol against superoxide, hydrogen peroxide (H
2
O
2
) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals were also investigated. In experimental period, mice were divided into six groups and the groups were treated with tap water, 10 mg/kg b.w resveratrol, 20 mg/kg b.w resveratrol, 20 µg/kg b.w. AFB

, 10 mg/kg b.w resveratrol + 20 µg/kg b.w AFB
2
, 20 mg/kg b.w resveratrol + 20 µg/kg b.w AFB

, respectively. As a result, the scavenging effects of resveratrol increased with increasing dose and the superoxide, H
2
O
2
and DPPH radical scavenging activity of resveratrol were 74.9%, 79.1% and 49.2%, respectively. AFB
2
administration caused a significant decrease in physiological parameters, and these decreases regressed in AFB
2
+ resveratrol treated groups. Serum ALT and AST activities, BUN and creatinine levels were higher in the AFB
2
treated group compared to the control group and serious abnormalities were found in MDA and GSH levels in the kidney and liver. In the group treated with AFB
2
+ 20 mg/kg resveratrol, ALT, AST, BUN and creatinine levels decreased significantly and GSH levels increased compared to only-AFB
2
treated group. AFB
2
triggered MN formation in buccal epithelium, erythrocyte and leukocyte cells and CAs in bone marrow cells. The application of 20 mg/kg resveratrol together with AFB
2
was decreased the MN and CAs frequency. Resveratrol exhibited a recovery effect in the range of 40.9–80.5% against AFB
2
toxicity in all tested parameters. In this study, it was determined that AFB
2
caused serious changes in selected physiological, biochemical and cytogenetic parameters while resveratrol displayed a protective role against these toxic effects. |
