Abstract:
Objective To investigate the effects of aloperine (ALO) on a model of dextran sulphate sodium (DSS)-induced chronic colitis in C57BL/6 mice.Methods Repeated colitis was induced by administration of four cycles of 4％ DSS.The severity of colitis was assessed on the basis of clinical signs,ratio of colon weight and colon length,and histological grading scores.Moreover,secretory immunoglobulin A (S-IgA) and plasma haptoglobin (HP) were analyzed by enzyme-linked immunosorbent assay,and the changes of mRNA expression of ICAM-1and MIF gene in colorectal tissue were detected by quantitative reverse transcriptase real-time polymerase chain reaction using SYBR Green Ⅰ.Results ALO administration significantly attenuated the colon damage,caused substantial reductions of the rise in HP,and maintained the level of cecum S-IgA.ALO inhibited the ICAM-1mRNA expression and had no effect on MIF mRNA expression.Conclusion The effect of ALO on DSS-induced chronic colitis in mice is investigated for the first time,which suggests that ALO could be an attractive therapeutic candidate in the treatment of inflammatory bowel disease.
