Abstract

 

 Objective: Citrus fruits are commonly consumed for their health benefits and contain naringenin (Nrg) as the major flavanone. The objective was to investigate the anti-inflammatory effect of Nrg by applying ethanol (EtOH) and cerulein (Cer) induced model of pancreatitis.

Methods: Male albino Wistar rats were divided into four groups. Group 1 and 2 were fed normal diet. Group 3 and 4 were fed isocalorically adjusted diet containing EtOH (36% of total calories) for a total period of 5 weeks and also injected Cer intraperitoneally (20 μg/kg body weight) 3 times a week from 3rd week. In addition, Group 2 and 4 rats received daily 200 mg/kg body weight of Nrg orally from 3rd week till the experimental period of 5 weeks. Spectrophotometric assay of serum lipase, amylase, oxidative stress markers, and ELISA-based determination of inflammatory markers were carried out. The results were analyzed by one-way analysis of variance with post-hoc Bonferroni test.

Results: Nrg co-administration significantly decreased the levels of serum L/A ratio (18%, p=0.021), lipid peroxides, inflammatory markers interleukin‑1β (IL−1β) (18%, p=0.044), IL-18 (58%, p=0.000) and caspase-1 (31.4%, p=0.000), improved antioxidant status and minimized histopathological alterations in EtOH-Cer administered rats.

Conclusion: The ability of Nrg to reduce caspase-1 activity and maturation of proinflammatory cytokines could be the underlying mechanism for its anti-inflammatory action in pancreatitis.
