ABSTRACT
Objective To investigate the relationsheep between colonic H2 S‐producing enzyme cystathionine‐γ‐lyase(CSE) and colonic motility in a rat model of diabetes mellitus(DM) .Methods To obtained diabetic rat models ,all rats were injected intra‐peritoneally (ip) 1% streptozotocin (STZ ,65 mg/kg) ,type 1 diabetes model was established ,nornmol conditions were observed pe‐riodically .Ten days after treatment ,production of colonic longitudinal smooth muscle strips ,organ bath recordings were used to test the colonic motility ;immunofluorescence and double immunofluorescence lableling method were performed to detect the distribution of CSE;Western blot were performed on rat colonic samples devoid of mucosa and submucosa to detect the expression of CSE .Re‐sults DM rats decreased the colonic motility(P0 .05);DM rats increased the expression of CSE in the colon devoid of mucosa and sub‐mucosa(P<0 .05) .Conclusion The decrease of colonic motility in diabetic rat may be associated with the increased production of H2 S‐producing enzyme CSE .
