| 摘 要： | 目的:探索腹腔注射丁酸盐对防止乙酸性结肠炎的疗效。创新点:首次对大鼠进行腹腔注射丁酸盐,通过与直肠灌注和口服比较,探索三种不同给药方式对预防乙酸性结肠炎的疗效差异。方法:以40只Wistar大鼠为实验对象,分组进行连续7天的腹腔注射、直肠灌注和口服100 mg/kg丁酸钠(SB),第8天进行乙酸(AA)直肠灌注,48小时后处死。记录实验大鼠的临床症状,包括体重减少、腹泻、便血等。对结肠切片进行组织病理学观察,最后对试验数据进行统计分析。结论:腹腔注射、直肠灌注和口服丁酸盐均能明显缓解大鼠乙酸性结肠炎的炎症,其中以腹腔注射疗效最佳。

| Abstract: | Intrarectal infusion of butyrate improves colorectal disorders including ulcerative colitis (UC). However, it is not established whether systemically administered butyrate benefits such patients. The current study aimed at exploring and comparing the potential of intraperitoneally, intrarectally, and orally administered butyrate against acetic acid (AA)-induced UC in rats. Intrarectal administration of 2 ml of 50% AA was done after or without prior treatment of rats for 7 consecutive days with 100 mg/kg sodium butyrate (SB) intraperitoneally, intrarectally, or orally. Rats were sacrificed after 48 h of AA-treatment. Subsequently, colon sections were processed routinely for histopathological examination. We clinically observed diarrhea, loose stools, and hemoccult-positive stools, and histologically, epithelial loss and ulceration, crypt damage, goblet cell depletion, hemorrhage, and mucosal infiltration of inflammatory cells. The changes were significantly reduced by intraperitoneal, intrarectal, or oral butyrate, with intraperitoneal butyrate exhibiting the highest potency. It is concluded that intraperitoneal administration of butyrate abrogates the lesions of AA-induced UC and its potency surpasses that of intrarectal or oral butyrate. |
