Therapeutic effect of adenosine on experimentally induced acute ulcerative colitis model in rats

Abstract Purpose To examine the therapeutic effect of external adenosine on an acetic acid-induced acute ulcerative colitis model in rats. Methods Thirty male mature rats were divided into three groups as control, acute colitis (AC) and AC+adenosine group (AC+AD). AC was induced by rectal administration of 4% acetic acid (AA). 5mg/kg/day adenosine was performed i.p for 4 weeks to AC+AD group. Rectum and colon were excised for microscopic and histopathological histopathologic evaluations, and immunohistochemical analysis of nuclear factor kappa B (NF-kB). Blood samples were collected for biochemical detection of TNF-α, Pentraxin-3 and malondialdehyde (MDA) levels. Results AC group had generalized hyperemia and hemorrhage with increased macroscopic and histopathological scores compared with control (P
