1T1影像高信号肾脏病变:DWI与MR增强检查鉴别诊断的比较显示文摘目的比较测量MR扩散加权成像(DWI)的表观扩散系数(ADC)与MR增强检查对鉴别不含脂肪T1高信号肾脏病变的能力。以组织病理学分析和随访影像作为参照标准。方法机构伦理审查委员会批准了符合HIPAA法案的回顾性研究计划,免除知情同意。2位观察者独立回顾性分析41例在MR T1影像上呈高信号的肾脏病变。MRI检查包括DWI和T1对比增强成像。对每一人组病变,观察者评价(a)ADC均值(±标准差)、(b)增强率和(C)为确定增强的存在而做的减影影像(可信性评分,1~5分)。S.

3Heavy metal concentrations in soils and plants in the vicinity of Arufu lead-zinc mine, Middle Benue Trough, Nigeria显示文摘This study focused on the influence of base metal mining on heavy metal levels in soils and plants in the vicinity of Arufu lead-zinc mine, Nigeria. Soil samples (0-15 cm depth) and plant samples were collected from cul-tivated farmlands in and around the mine, the unmineralized site and a nearby forest (the control site). The samples were analyzed for heavy metals (Fe, Zn, Mn, Cu, Pb, Cr and Cd) by Atomic Absorption Spectrophotometry (AAS). The physical properties of soils (pH and LOI) were also measured. Results showed that soils from cultivated farm-lands have neutral pH values (6.5-7.5), and low organic matter contents (<10%). Levels of Zn, Pb and Cd in culti-vated soils were higher than the concentrations obtained from the control site. These heavy metals are most probably sourced from mining and agricultural activities in the study area. Heavy metal concentrations measured in plant parts decreased in the order of rice leaves>cassava tubers>peelings. In the same plant species, metal levels decreased in the order of Zn>Fe>Mn>Cu>Pb>Cr>Cd. Most heavy metals were found in plant parts at average concentrations normally observed in plants grown in uncontaminated soil, however, elevated concentrations of Pb and Cd were found in a few cassava samples close to the mine dump. A stepwise linear regression analysis identified soil metal contents, pH and LOI as some of the factors influencing soil-plant metal uptake.Nganje T.N. Adamu C.I.
