雌激素對小腸葡萄糖吸收的調(diào)節(jié)及機(jī)制研究
發(fā)布時間:2021-09-17 10:50
目的:葡萄糖在小腸的吸收過程是維持機(jī)體能量平衡的條件,而雌激素則對機(jī)體起著多方面的調(diào)節(jié)作用。相關(guān)研究發(fā)現(xiàn)雌激素參與調(diào)節(jié)了小腸葡萄糖的吸收,但吸收機(jī)制卻被長期忽視。因此,在本項研究中,我們對雌激素在十二指腸葡萄糖吸收中的影響及其機(jī)制進(jìn)行研究,旨在為臨床上肥胖的治療提供理論依據(jù)。方法:1.選擇20-30歲月經(jīng)周期規(guī)律的健康女性志愿者12人,分別在月經(jīng)期(為體內(nèi)雌激素水平最低時期)和排卵期(為體內(nèi)雌激素水平最高時期)口服50%葡萄糖行葡萄糖耐量試驗(oral glucose tolerance test,OGTT)后,測定血中葡萄糖水平的變化情況。2.動物模型的建立:選擇6周齡性成熟期C57雌鼠80只,分別在全麻下進(jìn)行假手術(shù)和卵巢切除術(shù),把40只去卵巢雌性C57小鼠作為去卵巢組,40只假手術(shù)雌性C57小鼠作為假手術(shù)組。(1)手術(shù)第二天起,每天早上十點(diǎn)定時稱量小鼠體重。(2)手術(shù)兩周后:(1)處死小鼠,經(jīng)腔靜脈抽血,運(yùn)用放射免疫法(radioimmunoassay,RIA)測定雌二醇水平。(2)采用Ussing chamber實驗觀察假手術(shù)組(5只)與去卵巢組(5只)在十二指腸黏膜葡萄糖吸收引...
