Abstract
It has been shown that beta-glucan (BG), which has antioxidant and immunomodulatory effects, attenuats renal ischemia-reperfusion injury. We aimed to investigate whether BG might have a preventive role against the development of contrast-induced nephropathy and to compare its effect with nebivolol (Nb) and N-acetylcysteine (NAC). Thirty-six Wistar albino female rats were randomly divided into six groups (n = 6 each): control, contrast media (CM), BG, BG + CM, Nb + CM, and NAC + CM. With the exception of control and CM groups, the others were given drugs orally once a day for 5 days. Kidney function parameters, inflammatory parameters, and serum and renal tissue oxidative stress markers were measured. Increases of serum creatinine and blood urea nitrogen levels were significantly higher (p < 0.05) in the CM group only. Absolute changes of serum creatinine levels in BG, BG + CM and Nb + CM groups were significantly lower than those in the CM group (p < 0.05). Serum levels of advanced oxidation protein products and malondialdehyde were significantly less (p < 0.05) in the BG group compared to the CM group. Histopathological lesions in the CM group were more advanced (p < 0.05). No significant differences between the BG + CM, Nb + CM and NAC + CM groups were found with regard to histopathological findings. This study suggests that BG protects or ameliorates against contrast-induced nephropathy. Its beneficial effects may be similar to or greater than those of Nb or NAC.
