摘要:


文题释义:

间日给食是指连续两次给食时间间隔24 h,使得实验鼠不能正常饮食,是一种在实验过程中喂养方面影响的处理措施,是消化不良实验动物模型制备的常见饲养方法。

功能性消化不良(Functional dyspepsiaFD)是指具有上腹部疼痛、胀痛、以及饱腹感、嗳气、食欲不振、恶心、呕吐等多种不适症状,经检查排除引起上述症状的器质性疾病的一组临床综合征。症状可持续或反复发作,频率为过去6个月中,症状发生3个月以上,是临床上最常见的一种功能性胃肠病。

背景:制备适宜的功能性消化不良小鼠模型能够为后续临床治疗和用药研究提供可靠的动物模型。

目的:运用联合多因素方法造模制备成年小鼠功能性消化不良模型。

方法60只昆明小鼠随机分为空白对照组和模型组,每组30只。空白对照组小鼠每日灌胃2%蔗糖溶液0.2 mL,持续8 d。模型组在经典碘乙酰胺造模方法联合间日给食的基础上,放入水箱中持续游泳20 min1 h后给予左旋精氨酸溶液5.7 g/kg灌胃,持续5 d,从第6天开始给予冷大黄水煎液2.9 g/kg灌胃3 d。观察小鼠行为学变化及光镜下病理形态学变化来确定成模效果。实验方案经承德医学院动物实验伦理委员会批准(批准号为CDMULAC-20191113-011)。

结果与结论:与对照组相比,模型组小鼠出现了毛发不光、拱背、体质量呈现下降趋势等特征变化,小肠推进率与胃内容物排空率均有下降现象,光镜下观察胃组织、肠组织切片显示有轻度损伤现象;提示在成年小鼠中运用联合多因素造模方法能够成功制备功能性消化不良模型,并且此种方法所制备的动物模型小鼠没有明显坏死、糜烂等器质性病变,说明此种制备成年功能性消化不良小鼠模型的方法可行。

Abstract:

BACKGROUND: A suitable rat model of functional dyspepsia is a reliable animal model for subsequent clinical treatment and drug research.

OBJECTIVE: To prepare a model of functional dyspepsia in adult mice using a combined multi-factor method.

METHODS: Sixty Kunming mice were randomly divided into a blank control group and a model group, with 30 mice in each group. The mice in the blank control group were orally administered 0.2 mL of a 2% sucrose solution for 8 continuous days. Based on the classic iodoacetamide modeling method combined with daily feeding, the model group was subjected to force swimming in a water tank for 20 minutes, and 1 hour later, the mice were orally administered 5.7 g/kg L-arginine solution for 5 days, followed by oral administration of cold rhubarb decoction 2.9g/gk for another 3 days. The behavioral and pathological changes under light microscope were observed to determine the modeling effect. The study protocol was approved by the Animal Ethic Committee of Chengde Medical College, No. CDMULAC-20191113-011.

RESULTS AND CONCLUSION: Compared with the control group, the model group showed a reduction in hair color, arch back and body mass, and the intestinal propulsion rate and gastric emptying rate both had a downtrend. Intestinal tissue sections showed mild damage under the light microscope. Therefore, the combined multi-factor modeling method used in in the adult mice can successfully prepare the functional dyspepsia model. Moreover, the animal model prepared by this method has no obvious organic lesions, such as necrosis and erosion, indicating that this is a feasible method to prepare the adult mouse model of functional dyspepsia.
