Overview

Controlled animal study demonstrates that 1,8-cineole alleviates potassium dichromate-induced nephrotoxicity in rats, suggesting therapeutic potential against heavy metal kidney injury.

Key Points

  • To evaluate the protective effects of 1,8-cineole against potassium dichromate-induced renal toxicity and examine its influence on oxidative stress, inflammation, and apoptosis.
  • Randomized 40 male Wistar albino rats into five treatment groups (n=8 per group): control, vehicle, potassium dichromate (PD), 1,8-cineole (CN), and PD combined with CN.
  • Administered all treatments orally once daily for 28 consecutive days.
  • Measured renal oxidative stress markers (MDA, GSH, CAT, SOD), inflammatory cytokines (NF-κB, TNF-α), Bax apoptotic expression via immunohistochemistry, and histopathological changes.
  • Potassium dichromate exposure induced significant renal damage, marked by increased levels of MDA, NF-κB, and TNF-α alongside depleted GSH, SOD, and CAT activities.
  • Co-treatment with 1,8-cineole counteracted potassium dichromate-induced alterations, suppressing oxidative stress, inflammatory mediators, and renal tissue injury.
