Objective:The study mainly utilize the raphanus which is a edible Chinese officinal herb and has little side-effect, easily accepted, steadly effect, and so on, to exploit its pharmacological value on gastrointestinal motility. By observing the effects of the crude extract of radishon the electrogastrogram,gastric emptying and small bowel peristalsis activity of the rats in vivo ,the effects of Ecr on gastrointestinal motility could be manifested. Furthermore, the contrast study about the effects of gastrointestinal motility was also observed among Ecr domperidone and prepulsid. The mechanism was explored by observing Ecr on the expression of Fos protein of the dorsal vagal complex.

目的：本研究主要利用十字花科萝卜属植物白萝卜作为食源性中药，具有副作用少、易被接受、作用稳定等特点，通过白萝卜提取物(The crude extract of radish，Ecr)对在体大鼠胃排空、肠推进、胃电活动的观察，并与经典的促胃肠动力药物进行对比观察，研究提取物对大鼠胃肠动力的作用；进一步通过研究提取物对大鼠中枢支配胃运动的迷走复合体(Dorsal vagal complex，DVC)中Fos蛋白表达的影响，从而反映DVC被激活的情况，来探讨白萝卜提取物促进胃肠动力的机制，从而为其在胃肠动力相关的功能性疾病的治疗上的应用提供实验基础和理论依据。

High unpredictability and asymmetry of interaction, coupled with an important influence of abioticfactors, means that the influences of mutual selection pressures between plants and seed dispersers aregreatly eonstrained.

L.monocytohenes widely exists in the nature, and is not easy to be freeze, and can bear high infiltrator pressure, so it can exist in soil, surface water, sewerage, waster water, plant, plant feed, fester vegetable, so the animal eat them into their body easily, and from mouth enter our body, it is said that 0.6-16% stool check from healthy person can also find listeriosis growing, and even can found 70% healthy person can carry listeriosis short time in their body.

单增李斯特氏菌广泛存在于自然界中，不易被冻融，能耐受较高的渗透压，在土壤、地表水、污水、废水、植物、青储饲料、烂菜中均有该菌存在，所以动物很容易食入该菌，并通过口腔-粪便的途径进行传播。据报道，健康人粪便中单增李氏菌的携带率为0.6-16%，有70%的人可短期带菌，4-8%的水产品、5-10%的奶及其产品、30%以上的肉制品及15%以上的家禽均被该菌污染。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
