【摘要】：目的观察头低位卧床以及电解银离子 (航天饮用水消毒剂之一 )对肠道双歧杆菌的影响。方法1) 5名健康男性青年进行 2 1d的头低位 - 6°卧床实验 ,收集卧床前后的粪便 ,测双歧杆菌数量。 2 ) 4组小鼠分别饮用不含银纯净水、银含量为 0 .2 0、0 .40、0 .60mg/L的饮水 1月 ,测肠粪中双歧杆菌的数量。3 ) 7名健康男性志愿者 ,连续饮用含银量 0 .2 0mg/L的饮水 16d ,取实验前、饮水第 3、10、16天的粪便 ,测双歧杆菌数量。结果 1 )卧床后被试者粪中双歧杆菌的数量 (lgn/g)较卧床前呈显著性减少 (P 0 .0 1)。 2 )小鼠肠粪混合样中的双歧杆菌数 (lgn/g)与饮水中的银离子含量呈显著性负相关 (r =- 0 .992 ,P 0 .0 1)。 3 )被试者饮用含银离子水后粪中双歧杆菌的含量较饮用前呈显著性减少 (P 0 .0 5 )。结论头低位卧床及饮用含电解银离子水均能导致肠道双歧杆菌数量的减少
[Abstract]:Objective to observe the effect of head-low bed rest and electrolytic silver ion (one of space drinking water disinfectants) on intestinal bifidobacterium. The head-low to 6 掳bed-rest experiment was carried out in 5 healthy young men for 21 days. The feces before and after bed rest were collected, and the quantity of Bifidobacterium was measured. 2) the mice of 4 groups drank pure water without silver, and the silver content was 0. 20% 0. 40. 0. 60 mg / L of drinking water January, measured the number of bifidobacterium in intestinal faeces (3. 3)) 7 healthy male volunteers. Drinking water containing 0.20 mg / L silver for 16 days, the feces of the 3rd day before the experiment were taken. Results 1) the number of bifidobacterium in feces after bed rest was significantly lower than that before bed rest (P 0. 01). There was a significant negative correlation between the number of bifidobacterium and the content of silver ions in drinking water. The content of Bifidobacterium in feces after drinking water containing silver ion was significantly lower than that before drinking (P0. 05). Conclusion both head-down bed rest and drinking water containing electrolytic silver ions can reduce the number of bifidobacterium in intestinal tract.
