Abstract
Gentamicin is an essential aminoglycoside antibiotic, but it is only used to treat severe bacterial infections due to its high nephrotoxicity in patients. We evaluated the preventive effects of diosmin (as a natural ingredient) on gentamicin-related kidney damage in rats. In this research, 28 male Wistar rats were divided into four groups: control, gentamicin (100 mg/kg (i.p.), daily for 1 week), gentamicin plus diosmin (50 mg/kg, p.o., daily for 2 weeks), and diosmin (50 mg/kg/day, p.o. for 2 weeks). After the final gavage, blood samples were collected for the determination of blood urea nitrogen (BUN) and creatinine. Kidneys are used for biochemical, inflammatory, and histological tests. The concentrations of creatinine, BUN, nitric oxide, malondialdehyde, tumor necrosis factor α (TNF-α), and interleukin 1 beta (IL-1β) were significantly increased. But, the level of glutathione and activities of catalase, glutathione peroxidase, and superoxide dismutase decreased during treatment with gentamicin. On the other hand, the concentrations of creatinine, BUN, nitric oxide, malondialdehyde, TNF-α, and IL-1β were significantly reduced, and the glutathione level, activities of catalase, and glutathione peroxidase were significantly increased via co-administration with diosmin. Diosmin had ameliorative impacts against gentamicin-related kidney injury due to its antioxidant and anti-inflammatory activities.
