Abstract:目的:考察去氨微乳结肠定向除氨作用,期望为肝性脑病的防治提供一种更直接有效的新方法.方法:将去氨微乳放入含不同氨浓度的人工结肠液中10 h,体外模拟胃肠转运时间与pH环境的实验:参照国际检测氨的方法分别测氨浓度变化,计算氨清除率;在氨检测装置中比较去氨微乳、空白微乳、水及乳果糖对氨的清除作用.结果:去氨微乳使含氨5 g/L与10 g/L的结肠液氨浓度均下降为0 g/L,使含氨20 g/L的结肠液氨浓度下降为0.521±0.135g/L(p<0.05).在含氨10 g/L与20 g/L的人工结肠液中对氨的清除率较在含酶的人工胃液与小肠液消化中显著提高(100%±O.00% vs 96.41%±O.84%:97.29%±2.67% vs 86.42%±2.63%,均p<0.05).去氨微乳清除氨的效果明显优于空白微乳、水及乳果糖.结论:去氨微乳本身具有很好的除氨作用,为清除肠道氨提供了新的方法,但其作用会受到胃与小肠消化的影响,需进一步优化其配方.
