Abstract Vitamin D can be harmful if taken for a long time, or taken in large acute dose, cause many problems including hypercalcemia. Here, we examined the protective effects of Eugenia Caryophyllata against vitamin D toxicity induced renal inflammation in rats. This study employed four experimental groups (n = 10) that underwent two months of treatment as follows: control group animal received saline (0.9% NaCl), vitamin D group that was received (100 mg/kg) of vitamin D, Eugenol group that was received Eugenol (100 mg/kg), vitamin D + eugenol group that was received vitamin D (100 mg/kg) then will be orally given Eugenol (100 mg/kg). The current study showed that a significant upregulation in the IL-2, TNF- α and iNOS gene expression levels caused by vitamin D compared to the control group. Eugenol treatment caused a significant decreased IL-2, TNF-α and iNOS activity and also upregulated gene expression levels. Histological features investigated showed that administered with vitamin D intoxication showed distinct alterations from that of the untreated control groups, such Shrinkage of glomeruli, hypercellularity of the glomeruli and necrosis. However, retreatment with Eugenol showed improvement in the histological features in by slight infiltration, fibrosis, minimal pleomorphism and less disarrangement and compared with that of Vitamin D treated rats. In conclusion, the Eugenol exhibited renoprotective effects against vitamin D-induced nephrotoxicity. These renoprotective effects could be achieved by the antioxidant and anti-inflammatory activities of the Eugenol. Thus, for vitamin D-induced nephrotoxicity, the use of Eugenol could be beneficial.
