Abstract: AIM To investigate the role of interleukin (IL)-1α,IL-1β and IL-10 in the pathogenesis and development of ulcerative colitis in rats with abnormal sapra syndrome.METHODS A rat model of abnormal sapra syndrome was used to develop UC using trinitro-benzene-sulfonic acid (TNBS)/ethanol.Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the differences in IL-1α,IL-1β and IL-10 mRNA expression levels in the colonic tissues between normal rats (control group) and UC rats with abnormal sapra syndrome (model group).RESULTS Rat signs,symptoms and colonic mucosa damage suggested that UC with abnormal sapra syndrome was successfully induced.qRT-PCR results showed that compared with the normal group,the expression of IL-1α,IL-1β and IL-10 mRNAs was significantly upregulated in the model group (P < 0.05).CONCLUSIONImbalance of inflammatory factors may occur in colon tissue of UC rats with abnormal sapra syndrome.
