Pentoxifylline has favorable preventive effects on experimental chronic pancreatitis model

Abstract

Background: To investigate the protective efficacy of pentoxifylline through biochemical parameters and histopathological scores in a caerulein- and alcohol-induced experimental model of chronic pancreatitis in rats.

Methods: A model of chronic pancreatitis with caerulein and alcohol was created in female rats of the genus Sprague Dawley. Pentoxifylline was administered in doses of 25?mg/kg (low dose) and 50?mg/kg (high dose) as a protective agent. Each group contained 8 animals. The groups were: group 1 (control group); caerulein?+?alcohol, group 2 (low-dose pentoxifylline group); caerulein?+?alcohol?+?pentoxifylline 25?mg/kg, group 3 (high-dose pentoxifylline group); caerulein?+?alcohol?+?pentoxifylline 50?mg/kg, group 4 (placebo); caerulein?+?alcohol?+?saline, group 5 (sham group); only saline injection.Rats were sacrificed 12?h after the last injection, and TNF-α, TGF-β, MDA, and GPx concentrations were measured in blood samples. The histopathologic examination was conducted by a pathologist who was unaware of the groups.

Results: The biochemical results of the treatment groups (group 2 and group 3) were statistically significantly lower compared with the control group (group 1) (p?p?p?>?.05), whereas the difference between the group 3 and the control group was statistically significant (p?Conclusions: As a result, pentoxifylline, which has anti-inflammatory and antioxidant properties, was shown to have protective efficacy in an experimentally generated model of chronic pancreatitis.
