砷中毒

Results We have got the result by tracing observation to 15 patients of arsenic poisoning:that there are more than 15 years from hyperkeratosis of skin caused by arsenic poisoning to cancer,average 17.5 years.

结果 通过15例砷中毒患者的追踪观察得出：砷中毒病人皮肤角化到癌变的间变期初步认为在15年以上，平均为17.5年，角化部位的外伤不易愈合，且易发生感染，是加速癌变的诱因，并分析了手、足皮肤角化点癌变发生率高的各种因素。

The specific aim of this study is to estimate the prevalence of chronic arsenicism among residentsin the BFD-endemic area after the discontinuation of drinking artesian well water. Arsenic exposure and skin lesions including hyperpigmentation, hyperkeratosis and cancer were studied.

本研究的目的在於了解饮水改善后，乌脚病盛行地区的皮肤砷中毒症盛行率；探讨砷暴露指标和皮肤砷中毒症的关系；并评估调整其他危险因子后，累积神暴露量对皮肤瘤的影响。

Traditionally, it was divided into acute and chronic arseniasis, which were decided mainly by exposing dose and time from exposure to attack.

传统砷中毒的概念分急性砷中毒和慢性砷中毒，它们主要是由于机体单位时间接触砷的量和从接触到发病的时间长短来决定。

A model was proposed to describe arsenic contamination of groundwater and its influencing factors controlling the processes of arsenic migration and enrichment, which can be used for the strategies making of arsenic contamination control in arseniasis areas.

在此基础上从砷的&来源－影响因素－影响过程－高砷形成&角度提出了地下水砷污染的成因模式，对砷中毒病区的环境问题调查与地下水砷污染的防治具有重要参考价值。

The main problem of arsenic in the north part of Xinjiang is the endemic arseniasis. The endemic arsenniasis in the north part of Xinjiang is related to the exploitation of deep groundwater.

北疆砷的问题主要是地方性砷中毒，北疆地方性砷中毒主要与深层地下水的开发有关。

The results show that the concentration of arsenic in blood of the arsenism mice is higher than that in the control mice.

用本法测定了慢性砷中毒小鼠红细胞中的砷含量，结果表明中毒组小鼠红细胞中砷含量显著高于对照组。

Objective To investigate whether high-arsenic area and endemic arsenism area exist in Anhui province in China.

目的了解安徽省是否存在水源性高砷区及地方性砷中毒区，为地方性砷中毒防治提供依据。

Objective: In order to analyse the valent state of Arsenic in water in KuiTun Xinjiang,and study the pathogenesis of arsenism.

Objective To study lipid peroxidation and anti-lipid peroxidation in the patients of arsenism caused by burning coal for clarifying the mechanism of this disease.

目的 研究燃煤型砷中毒患者体内氧化与抗氧化系统的损伤，以探讨燃煤型砷中毒的中毒机理。

Abstract］objective: to explore the relationship between arsenism and trace elements in hair of arsenism patients caused by coal-burning, so as to provide bases for theoretical study, diagnosis, and intervention of arsenism.

目的：检测燃煤污染型砷中毒患者头发中微量元素含量，探讨其与砷中毒的关系，为砷的毒作用机制分析及辅助性诊断和干预提供参考依据。
