Acetaminophen (APAP) is one of the popular and safe pain medications worldwide. However, due its wide availability, it is frequently implicated in intentional or unintentional overdoses where it can cause severe liver injury and even acute liver failure. Boron is a bioactive trace element, found naturally as boric acid (BA) and borate. In this study, the effects of boric acid on the acute renal toxicity induced by APAP in rats were researched in comparison with N-acetyl cysteine (NAC). In the study, 7 groups were formed and 2 g/kg dose of paracetamol per rat was prepared by suspending in 1% Carboxy Methyl Cellulose (CMC) solution of phosphate buffer saline (PBS). Boric acid dissolved in saline was administered to experimental animals by gavage at doses of 50, 100, and 200 mg/kg. In this study, ER stress and apoptosis formed by paracetamol-induced nephrotoxicity were investigated. This purpose determined iNOS, PERK, ATF6, NFkB p53, caspases 3, 12, bcl-2, and bcl-xL gene mRNA expression kidney tissue. Also, the levels of kidney injury molecule-1 (KIM-1), Cysteine (Cys), and IL-18 levels, which are mentioned today as kidney damage markers were compared with BUN and creatine levels. The effect of boron on kidney damage was determined by histopathologic. Data were statistically analyzed by using SPSS-20 ANOVA and stated as means and standard deviation. According to the data obtained in our study, we believe that boric acid has a protective effect on the negative effects of paracetamol on the kidney. We believe that our study will provide useful data to the literature on the possibility of a supplement to be used as an active compound in paracetamol for the prophylaxis of boric acid and it can also be converted into a useful product.
