Aim: Acute kidney injury develops as a result of various etiologies and pathological mechanisms, with a high mortality rate. This study aimed to investigate the efficacy of Anatolian syrup on histopathological variables in experimentally induced acetaminophen and lipopolysaccharide associated acute kidney injury.

Methods: In this study, 5 groups were formed using 40 male Wistar albino rats (200-220g, 2-4 months old), as follows: Sham, acetaminophen (1 g/kg intraperitoneal (ip)), 3) lipopolysaccharide (5 mg/kg ip), acetaminophen (1 g/kg ip) + Anatolian syrup (15 days orally), and lipopolysaccharide (5 mg/kg ip) + Anatolian syrup (15 days orally).Tubular atrophy, tubular dilatation, cytoplasmic vacuolization in tubular epithelial cells, tubular epithelial cell necrosis, interstitial inflammation, congestion, hemorrhage, glomerular damage and loss of brushy border were evaluated histopathologically semiquantitatively using scoring from 0 to 5.

Results: In histopathological variables, tubular atrophy, tubular dilatation, cytoplasmic vacuolization, necrosis, congestion, hemorrhage, glomerular damage, and loss of brushy border were significantly reduced in the acetaminophen + Anatolian syrup group compared to the acetaminophen group and in the lipopolysaccharide + Anatolian syrup group compared to the lipopolysaccharide group (p<0.001).

Conclusion: The Anatolian syrup was shown to protect histopathological variables in kidney damage caused by acetaminophen and lipopolysaccharide.
