Abstract
While physicians describe drugs to treat diseases, these medications may have cytotoxic effects on certain organs, necessitating the use of some drugs to ameliorate such adverse effects. The study was conducted to investigate the protective behavior of nanoemulsified sodium salicylate on uninephrectomized rats injected with cisplatin to induce nephrotoxicity. Fifty adult male albino rats, aged five weeks and weighing approximately 100-120 g, were divided into five groups. The first group received 200 mg/kg/day i.p normal saline for 30 days. The second group was administrated 200 mg/kg/day of nanoemulsified salt of salicylic acid for 30 days. The third group, comprising uninephrectomized rats, was injected with two doses of cisplatin (20 mg/kg body weight) on alternate days from the start of the experiment to induce nephrotoxicity. The fourth group, also uninephrectomized, received 200 mg/kg/day i.p of nanoemulsified sodium salicylate for 30 days. The fifth group, uninephrectomized and treated with 200 mg/kg/day sodium salicylate nanoemlusion for 21 days, was subsequently injected with two doses of cisplatin, followed by continued nanoemulsified sodium salicylate treatment until day 30 from the start of the study. The results showed a significant increase in tissue inhibitor metalloproteinase 1 (TIMP-1), Hyaluronic acid (HA), malondialdehyde, kidney injury molecule -1(KIM-1), and nitric oxide in the nephrotoxic group injected with cisplatin compared to the control group. Additionally, there was an elevation in the mRNA expression of nephrotoxic group with uninephrectomy. However, nephrotoxic rats treated with nanoemulsified sodium salicylate exhibited only a modest increase in TIMP-1, HA, and KIM-1 levels, along with elevated expressions of podocin and nephrin compared to the healthy control group. These findings suggest that nanoemulsified sodium salicylate exerts a protective effect against cisplatin-induced nephrotoxicity in uninephrectomized.
