小赵因双眼发红,分泌物多,到药店买了一瓶利福平眼药自行滴眼治疗。然而用药后不仅没有效果,症状反而加重。原来她用药前没有按说明书要求将眼药配好,还犯了一个啼笑皆非的错误——把本应放入药瓶中溶解的药丸,当作口服药服到肚子里了…… 相似文献

体育锻炼纠正心理缺陷,不是一般的运动训练和娱乐游戏活动。要想达到心理转移的目的,必须有一定的强度、质量和时间的要求。每天锻炼时间在30分钟左右,运动量从小到大,循序渐进。 相似文献

Determinations of benzene concentration in blood and of phenol in urine were made by head-space gas chromatography techniques on samples taken near the end of the work day from two groups of workers potentially exposed to low levels of benzene in the work-place atmosphere. Preliminary results suggest that benzene in blood is more reliable than phenol tests for assessing both exposure and uptake of benzene. Normal values of phenol in urine (10 mg/liter or less) were found in nearly all those cases in which benzene was detected in the blood. 相似文献

BACKGROUND: Ragpickers are informal workers who collect recyclable materials to earn a small wage. Their life and working conditions are extremely precarious. The ergonomic hazards and musculoskeletal pain in a sample of ragpickers in Pelotas, a city in southern Brazil are examined. METHODS: Two comparison groups were available: a matched sample of non-ragpickers from the same poor neighborhoods, and a random sample of the general population of the city. The cross-sectional study gathered data by interview on 990 individuals in 2004. Musculoskeletal pain was assessed using the Standardized Nordic Questionnaire. RESULTS: Ragpickers reported higher prevalences for most awkward postures and ergonomic exposures compared to neighbors with other demanding manual jobs. The prevalence within the last 12 months of low back pain (LBP), lower extremity pain (LEP), and upper extremity pain (UEP) among ragpickers were 49.2%, 45.1%, and 34.9%, respectively; levels similar to those reported by neighborhood controls. Both ragpickers and non-ragpickers reported considerably higher ergonomic exposures, and more prevalent LBP, than the general population. CONCLUSIONS: Ragpickers experience many occupational hazards and ergonomic stressors. Their overall prevalence of musculoskeletal pain was similar to a comparison group with other physically demanding manual jobs. For LBP, this prevalence was substantially higher (49% vs. 35%) than in the general population. 相似文献

目的了解张家港市区从业人员沙门菌属的带菌情况及流行趋势,以有效控制相关传染病的发生。方法对张家港市2005-2009年121 370名进行健康体检的从业人员肛拭样品沙门菌检测结果进行分析结果共检出沙门菌菌株373株,总检出率为0.31%,2005-2009年沙门菌检出率分别为0.52%、0.37%、0.24%、0.22%和0.23%,夏秋季沙门菌的检出率明显高于冬春季(χ2=140.503,P〈0.01),从检出的373株沙门菌的血清型分布情况看,该地区主要以B、C、E群为多见,血清型以德尔卑占优势,其次为山夫登堡、罗米他。结论 2005-2009年张家港市从业人员沙门菌检出率呈逐年下降趋势,且有明显季节区别。 相似文献

Objective: The objective of this study is to examine if overall correlation exists among cadmium levels (Cd) in the general environment,
dietary Cd intake, and Cd body burden of local residents. Methods: Eleven prefectures in Japan were selected as the areas where large-scale data on Cd levels in urine of adult women (40–49
and 50–59 years of age, respectively) were available to calculate geometric mean (GM) values for each of the prefecture. Other
data were cited from published or previously established databases on Cd in the sediments of river bottoms (as a representative
of Cd in the environment), Cd in rice for local consumption, and Cd in daily food duplicate samples collected from local women
populations, and calculated for GM values for the prefectures. The GM values were subjected to correlation matrix and regression
analysis. Results: Marginally significant (P<0.10) correlation was detected between Cd in sediment and Cd in rice. Furthermore, correlation of Cd in sediment was significant
with Cd in total foods (P<0.05) and possibly with Cd in urine (P<0.05–0.10). Importance of data on Cd in rice paddy soil as a missing link is discussed. Conclusions: Correlation was demonstrated in the flow of Cd transport from the environment (expressed as Cd contents in river sediments)
to humans (in terms of Cd in urine) among general populations in Japan. 相似文献
