Abstract
Background:
The modulating effect of methanolic extract of Emblica officinalis (MEEO) on ethanol (EtOH)- and cerulein (Cer)-induced pancreatitis in rats was investigated in this study.
Methods:
Male albino Wistar rats were divided into four groups. Group 1 and 2 rats served as control and fed normal diet. Group 3 and 4 rats were fed isocalorically adjusted diet containing EtOH (36% of total calories) for 5 weeks and also subjected to intraperitoneal injection of Cer 20 µg/kg b.wt. thrice weekly for the last 3 weeks of the experimental period. In addition, group 2 and 4 rats received 200 mg/kg b.wt. of MEEO from 15th day till the experimental period. Serum levels of lipase (L), amylase (A), cytokines IL-1β, IL-18, caspase-1 and oxidative stress index (OSI) were determined. Levels of fecal trypsin, total collagen, caspase-1, myeloperoxidase (MPO), antioxidants and mRNA expression of caspase-1, IL-1β and IL-18 were determined in the pancreas.
Results:
HPLC analysis showed the presence of rutin in MEEO. We observed a significant elevation in serum L/A ratio, IL-1β, IL-18, caspase-1, OSI, collagen, MPO activity and the mRNA expression of IL-1β, IL-18 and caspase-1 and significant reduction in fecal trypsin and antioxidant status in EtOH- and Cer-administered rats. The inflammatory markers were found to be reduced and the antioxidant status of pancreas was maintained in MEEO-coadministered rats.
Conclusions:
The rutin rich nature of E. officinalis can be claimed for its anti-inflammatory and pancreato protective effects.
