目的:观察坦克作业对乘员肾脏功能的影响。方法:在我军某坦克部队随机选取152名坦克乘员为观察组,在同一部队选取非坦克作业战士37名为对照组。留取24h尿和晨尿,检测尿中α1-微球蛋白(α1-MG)、β2-微球蛋白(β2-MG)、IgG、N-乙... 目的:观察坦克作业对乘员肾脏功能的影响。方法:在我军某坦克部队随机选取152名坦克乘员为观察组,在同一部队选取非坦克作业战士37名为对照组。留取24h尿和晨尿,检测尿中α1-微球蛋白(α1-MG)、β2-微球蛋白(β2-MG)、IgG、N-乙酰-β-葡萄糖苷酶(NAG)和尿微量白蛋白(UAE)排泄率。结果:与对照组比较,观察组尿α1-.MG、β2-MG、尿NAG、尿UAE均明显升高,且平均值均超过临床检验正常值,尿IgG无明显升高。其中从事坦克作业50摩托小时以上的坦克乘员尿中β2-MG、NAG、UAE均高于对照组(P〈0.05),从事坦克作业51~100摩托小时的尿中α1-MG虽有升高,但未有统计学差异且平均值在正常范围内,从事坦克作业大于301摩托小时的坦克乘员尿中α1-MG显著高于对照组。脱离坦克作业3年后乘员尿中β2-MG、NAG、UAE降低至正常水平,但大于10年者尿中β2-MG再度出现升高,与6—10年组比较有显著差异(P〈0.05)。脱离坦克作业后坦克乘员尿中α1-MG虽有下降,但始终未降至正常水平。结论:坦克作业对乘员肾脏功能有一定影响,脱离坦克作业后乘员肾功能可得到较好的恢复,但远期仍遗留一定程度的肾小管重吸收功能障碍。 展开更多

Conservation agriculture (CA) is especially relevant for Uzbekistan's agriculture, particularly in non-irrigated lands where soil fertility has been steadily declining and the risk of crop failure has been growing. CA has three main characterizations given in scientific literature, which are the minimal soil disturbance, crop rotation and surface crop residue retention. Nowadays, the majority of farmers are not widely using CA in their agricultural practices in Uzbekistan. Maybe, this is due to different perception of the economic efficiency of CA. The objective of the research was to calculate economic efficiency of CA in non-irrigated lands and to show whether it is effective or not in agricultural production. To achieve this objective, literature review including a variety of secondary data is employed. Overall, the costs of labor and fuel consumption per ha at CA technology are less in comparison with conventional technology. Using CA practices gives a chance to increase labour productivity, to use resource effectively and to improve soil quality and crop diversification. 展开更多
