【摘要】：目的了解野外训练环境条件对坦克乘员肠道双歧杆菌的影响。方法通过活菌定量培养计数法 ,动态观察 32例参训坦克乘员和 30例非坦克乘员粪便中双歧杆菌数 (B)和大肠杆菌数 (E)及B/E值。运用SPSS/P +软件包进行多元逐步回归分析 ,判断参训坦克乘员肠道双歧杆菌数与训练环境因素各变量之间的关系。结果坦克乘员组参训后第 30天和第 5 9天粪便中双歧杆菌数分别为 (8.35± 0 .4 8)lgcfu·g- 1和 (8.4 1± 0 .4 9)lgcfu·g- 1;大肠杆菌分别为 (8.0 5± 0 .4 3)lgcfu·g- 1和 (7.97± 0 .4 1)lgcfu·g- 1;B/E值分别为 1.0 4± 0 .0 8和 1.0 6± 0 .0 8。参训前粪便中双歧杆菌和大肠杆菌数分别为 (9.5 5± 0 .4 2 )lgcfu·g- 1和 (7.0 1± 0 .2 0 )lgcfu·g- 1,B/E值为 1.36±0 .0 7。非坦克乘员组粪便中双歧杆菌数和大肠杆菌数分别为 (9.2 7± 0 .6 5 )lgcfu·g- 1和 (6 .93±0 .2 9)lgcfu·g- 1,B/E值为 1.34± 0 .11。坦克乘员组参训后与参训前及对照组比较 ,粪便中双歧杆菌数量均显著减少 (P 0 .0 1) ,大肠杆菌数均显著增多 (P 0 .0 1) ,B/E值均显著降低 (P 0 .0 1)。多元逐步回归分析并按标准回归系数大小排列 ,对参训坦克乘员肠道双歧杆菌数量有显著意义 (P 0 .0 5 )的影响因素有 :噪声、乘室空间、有
[Abstract]:Objective to investigate the effect of field training environment on intestinal bifidobacteria of tank crew. Methods the number of bifidobacillus (B) and Escherichia coli (E) and B / E in the feces of 32 tank crew and 30 non-tank crew were observed dynamically by the method of quantitative culture and counting of living bacteria. Multiple stepwise regression analysis was carried out by SPSS/P software package to judge the relationship between the number of Bifidobacterium in intestinal tract and the factors of training environment. Results the number of Bifidobacillus in feces of tank crew group was (8.35 卤0.48) lgcfu 路g ~ (- 1) and (8.41 卤0.49) lgcfu 路g ~ (- 1) on the 30th and 59th day after training, respectively. The B / E values of Escherichia coli were (8.05 卤0.43) lgcfu 路g-1 and (7.97 卤0.41) lgcfu 路g-1 and 1.06 卤0.8, respectively. The number of bifidobacillus and Escherichia coli in feces before training was (9.55 卤0.42) lgcfu 路g-1 and (7.01 卤0.20) lgcfu 路g-1, respectively, and the B / E ratio was 1.36 卤0.07. The number of bifidobacillus and E. coli in feces of non-tank crew group were (9.27 卤0.65) lgcfu 路g ~ (- 1) and (6.93 卤0.29) lgcfu 路g ~ (- 1), respectively, and the B / E ratio was 1.34 卤0.11. After training, the number of Bifidobacterium in feces of tank crew group was significantly lower than that before training and control group (P 0.01), and the number of Escherichia coli was significantly increased (P 0.01).
