【摘要】 目的  研究肥大細胞膜穩定劑色甘酸二鈉(disordium cromoglycate,DC)對葡聚糖硫酸鈉(dextran sulfate sodium,DSS)誘導的大鼠急性結腸炎的影響。 方法  出生80~100 d的雄性SD清潔級大鼠30只,體重180~250 g。30只大鼠隨機分為3組:正常對照組(A組)、潰瘍性結腸炎組(B組)和DC組(C組),每組各10只。B組和C組自由飲用40 g/L DSS溶液(4%) 7 d誘發急性結腸炎,同時C組每天按100 mg/kg腹腔注射DC 1次,A組和B組每天腹腔注射等量的生理鹽水。7 d后,處死各組大鼠。對各組大鼠行疾病活動指數評分,結腸組織行大體評分、組織學評分,檢測門靜脈血一氧化氮濃度,結腸組織髓過氧化物酶活性。 結果  疾病活動指數評分、大體評分、組織學評分、一氧化氮濃度及髓過氧化物酶活性均表現為B組 gt;C組 gt;A組(P lt;0.05)。 結論  肥大細胞膜穩定劑DC對DSS誘導的大鼠急性結腸炎有一定的保護作用。
【Abstract】 Objective  To observe the influence of the mast cell memebrane stabilizer, disordium cromoglycate (DC), on dextran sulfate sodium (DSS)-induced colitis in rats. 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 (P lt;0.05), but lower than those of group B (P lt;0.05). Conclusion  Disordium cromoglycate can protect the colon of rats with DSS-induced acute colitis.
