Abstract
The current investigation was considered to evaluate the beneficial effects of gentisic acid (GA) on gentamicin (GEN)-induced nephrotoxicity in rat kidneys through assessment of oxidative stress, inflammatory cytokines, and histopathological changes. Rats were split into five equal groups. Rats were treated with GA (25, 50, and 100 mg/kg/day, p.o.) for 14 consecutive days and GEN (100 mg/kg, i.p.) was administrated from day 8 to day 14 of the experiment. On the 15th day, blood samples were collected to determine neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), blood urea nitrogen (BUN), and creatinine (Cr) levels. Malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor-alpha (TNF-α) and interleukin-1β (IL-1β), and nitric oxide (NO) levels and the activities of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) were assessed in the renal tissue. Histopathological evaluations were done to confirm the biochemical results. GEN increased the levels of NGAL, KIM-1, BUN, and Cr in serum as well as MDA, NO, GSH, TNF-α, and IL-1β in renal tissue. Moreover, GEN administration reduced the activity of CAT, SOD, and GPx in renal tissue. Nonetheless, the administration of GA before and alongside GEN mitigated these deleterious effects. In conclusion, GA has a beneficial effect on biochemical, inflammatory, and oxidative stress indices against GEN-induced nephrotoxicity.
