Nf-κb在遗传性糖尿病长爪沙鼠多种组织中的表达状况

目的 探讨糖尿病长爪沙鼠6种组织中Nf-κb基因mRNA和蛋白的表达水平,以期探索长爪沙鼠糖尿病模型中Nf-κb的作用和靶器官。方法 选取糖尿病长爪沙鼠和正常血糖沙鼠各6只,分别采集动物的骨骼肌、肝脏、脂肪、肾脏、心脏和脑组织,用Q-PCR和Western blotting检测Nf-κb在各组织中mRNA和蛋白表达水平。结果 与对照动物相比,在糖尿病长爪沙鼠的肌肉、肾脏和脑组织中,Nf-κb基因的mRNA水平表达有升高趋势,脂肪中则显著降低,肝脏和心脏中仅有降低趋势。检测蛋白水平发现除肝脏外,其他组织的结果均与mRNA水平一致。结论 糖尿病长爪沙鼠脂肪组织是Nf-κb作用的靶器官。

Estimation of wind erosion rates by using 137Cs tracing technique: A case study in Tariat-Xilin Gol transect, Mongolian Plateau

Wind erosion is one of the major environmental problems in semi-arid and arid regions. Here we established the Tariat-Xilin Gol transect from northwest to southeast across the Mongolian Plateau, and selected seven sampling sites along the transect. We then estimated the soil wind erosion rates by using the 137Cs tracing technique and examined their spatial dynamics. Our results showed that the 137Cs inventories of sampling sites ranged from 265.63=44.91 to 1279.54=166.53 Bq. m-2, and the wind erosion rates varied from 64.58 to 419.63 t. km-2. a-~ accordingly. In the Mongolia section of the transect （from Tariat to Sainshand）, the wind erosion rate increased gradually with vegetation type and climatic regimes; the wind erosion process was controlled by physical factors such as annual precipitation and vegetation coverage, etc., and the impact of human activities was negligible. While in the China section of the transect （Inner Mongolia）, the wind erosion rates of Xilin Hot and Zhengxiangbai Banner were thrice as much as those of Bayannur of Mongolia, although these three sites were all dominated by typical steppe. Besides the physical factors, higher population density and livestock carrying level should be responsible for the higher wind erosion rates in these two regions of Inner Mongolia.     

Using 137Cs tracing technique to estimate wind erosion rates in the typical steppe region,northern Mongolian Plateau

Wind erosion is one of the major factors of land degradation in the typical steppe region, northern Mongolian Plateau. Using ^137Cs tracing technique, we estimated the wind erosion rates of different pastures and abandoned farmland at Bayannur and Karakorum in Mongolia. The pastures and cutting grassland at Bayannur were slightly eroded by wind, with the rates of 64.58-169.07 t·km^-2.a^-1. The abandoned farmland in Karakorum, however, was strongly eroded by wind, with annual surface soil loss of 4.05 mm. a^-1, and wind erosion rates up to 6723.06 t· km^-2. a^-1. The total loss of surface soil due to wind erosion has been 17.4 cm since the cultivation of the steppe land in the 1960s. The wind ero- sion rate at the abandoned farmland was much higher than that at the typical steppe sites, showing that the cultivation led to serious wind erosion in the typical steppe region, northern Mongolian Plateau. By contrast, traditional livestock grazing resulted in less disturbance to the surface soil, and did not induce to devastating wind erosion, which plays an important role in maintaining the stability of the steppe ecosystem in the northern Mongolian Plateau.

蒙古族水文化的历史记忆及意义分析

蒙古民族长期生活在干旱少雨的蒙古高原上,从事着逐水草而居的游牧生活。由于游牧业对水的过分倚重,使得水在牧民生产、生活中影响深广,形成了许多关于水的独特文化。对蒙古族的水文化进行历史追溯,揭示其形成原因和影响,仍有很强的现实意义。
