【摘要】:目的:觀察內(nèi)、外寒冷刺激對(duì)大鼠胃粘膜形態(tài)及相關(guān)功能的影響。通過對(duì)實(shí)驗(yàn)大鼠施加寒冷刺激因素,觀察大鼠胃粘膜局部病理改變及檢測(cè)血清和胃粘膜的胃動(dòng)素、胃泌素、前列腺素及內(nèi)皮素的變化,探討內(nèi)外寒冷刺激對(duì)大鼠胃粘膜功能狀態(tài)的影響,及良附丸的防治作用。 材料與方法: 1分組造模及用藥干預(yù):大鼠適應(yīng)性喂養(yǎng)3天,按體重隨機(jī)分為5組。正常對(duì)照組:用生理鹽水灌胃2mL/l00g,日2次;冰水浸泡組:用0℃冰水浸泡大鼠30min,水深為2cm,日1次;生理鹽水灌胃2mL/l00g,日1次;冰水灌胃組:用0℃冰水灌胃2mL/100g,日2次;復(fù)合刺激組:用0℃冰水浸泡大鼠30min,水深為2cm,用0℃冰水2mL/100g灌胃,日1次;中藥防治組:用0℃冰水浸泡大鼠30min,,水深為2cm,用0℃冰水2mL/100g灌胃,日1次,同時(shí)給予良附丸溶液灌胃,日1次,灌胃時(shí)間間隔4小時(shí)以上。實(shí)驗(yàn)周期共7天。 2大鼠一般狀態(tài)的觀察:實(shí)驗(yàn)進(jìn)行過程中,對(duì)大鼠飲食,二便,精神狀態(tài),毛色,體重情況及死亡情況進(jìn)行觀察和記錄。 3取材及實(shí)驗(yàn)指標(biāo)檢測(cè):實(shí)驗(yàn)結(jié)束后,禁食不禁水12小時(shí),麻醉后,剖開大鼠腹腔,腹主動(dòng)脈采血4mL,檢測(cè)血清胃動(dòng)素、胃泌素、前列腺素,內(nèi)皮素;沿大彎側(cè)剪開鼠胃,生理鹽水沖洗,取胃體、胃竇組織檢測(cè)胃粘膜病理,及胃粘膜胃動(dòng)素、胃泌素、前列腺素,內(nèi)皮素含量。 結(jié)果: 1施加內(nèi)、外寒冷刺激可損傷大鼠胃粘膜形態(tài)。 2大鼠胃組織和血清中的胃動(dòng)素、胃泌素、6-keto-PGF2α水平降低,內(nèi)皮素水平升高。 3良附丸可改善大鼠受損的胃粘膜。 4良附丸對(duì)模型大鼠血清及胃粘膜中的胃動(dòng)素、胃泌素、6-keto-PGF2α水平,內(nèi)皮素的水平有一定調(diào)整作用。 結(jié)論: 1寒性刺激可以使實(shí)驗(yàn)大鼠的胃粘膜造成病理性損傷。 2寒冷刺激可以使大鼠胃粘膜和血清的胃動(dòng)素、胃泌素、6-keto-PGF2α水平降低;可以使內(nèi)皮素水平升高。 3冰水浸泡、冰水灌胃及復(fù)合因素對(duì)胃粘膜損傷的程度是不同的,復(fù)合因素?fù)p傷作用較重,冰水灌胃次之,冰水浸泡較輕。 4良附丸對(duì)寒冷刺激所致胃粘膜的損傷有一定防治作用。
[Abstract]:Aim: to observe the effects of cold stimulation on gastric mucosal morphology and related functions in rats. The changes of motilin, gastrin, prostaglandin and endothelin in serum and gastric mucosa were observed by applying cold stimulation to experimental rats. To investigate the effects of cold stimulation on gastric mucosal function and the preventive and therapeutic effects of Liangfu Pill in rats. Materials and methods: 1 the rats were randomly divided into 5 groups according to their body weight. The rats in the control group were perfused with normal saline twice a day, the rats in the ice water immersion group were soaked with ice water at 0 鈩
