摘要:賁門失弛緩癥是下食管括約肌松弛異常及食管體部缺乏推進(jìn)性蠕動(dòng)為特征的食管運(yùn)動(dòng)功能障礙性疾病。目前病因和發(fā)病機(jī)制不明,主要臨床表現(xiàn)為吞咽困難,胸痛和嘔吐。治療主要以減低下食管括約肌緊張性為目的。治療方法包括藥物治療、局部注射肉毒桿菌毒素、氣囊擴(kuò)張、外科手術(shù)治療及支架治療。支架治療作為近年來(lái)開(kāi)展起來(lái)的一項(xiàng)新的治療方法,有其獨(dú)特的優(yōu)勢(shì)及較好的療效,是一種有著較好前景的治療方法。

Methods Thirty male Sprague-Dawley (SD) rats aged 80 to 100 days with their weight ranged from 180 to 250 g were randomly divided into 3 groups: normal control group (group A), dextran sulfate sodium group (group B) and disordium cromoglycate group (group C), with 10 rats in each. Rats in group B and C drank 40 g/L DSS solution (4%) for 7 days to induce acute colitis. At the same time, intraperitoneal administration of DC (100 mg/kg) to rats in group C was carried out once a day, while the other two groups of rats were given the same amount of normal saline solution. Disease activity index (DAI), gross and histological evaluation were analyzed. NO concentration of blood from portal vein was measured. Myeloperoxidase (MPO) activity of colonic tissue was detected. Results The experimental data of group C, including DAI, gross evaluation, histological assessment, NO concentration and MPO activity, were all significantly higher than those of group A (Plt;0.05), but lower than those of group B (Plt;0.05). Conclusion Disordium cromoglycate can protect the colon of rats with DSS-induced acute colitis.
