文档介绍：攀枝花市克山病分布及相关环境因素研究
【摘要】目的研究攀枝花地区的硒元素背景值、克山病分布及相关环境因素,为我市克山病的防治工作提供了科学依据,并提出克山病病因学新理论。方法以我市44个乡镇辖区为调查对象,完成土壤、蔬菜、水果、粮食、生物材料、水等硒元素背景值检测工作;克山病分布和相关环境因素调查。结果我市属于缺硒地域,部分地区存在克山病;病人由过去的小孩转向青年。预测我市克山病有爆发流行的潜在可能性。研究中也发现许多缺硒村镇无1例克山病发生。结论地方性克山病发生在缺硒地区,但缺硒地区可能由于某些不明物质的介入而不发生克山病,缺硒不是克山病发生的唯一因素,只是克山病发生的原因之一,进一步证明地方性克山病发生的多因素理论,为地方性克山病、癌症、肿瘤防治工作提供科学依据。该研究项目提出的理论、实际应用、研究方法具有我国同类研究工作领先水平。

[Abstract] Objective To investigate the background value of Selenium and distribution and related environmental factors of Keshan disease in Panzhihua City to provide scientific basis for the prevention and treatment of Keshan disease. Methods Selenium contents were measured in soil, vegetables, fruits, rice, biological materials and water covering forty-four towns. The distributions of Keshan disease and related factors were studied as There were Se deficiency and patients with Keshan disease in Panzhihua City tended to be older. However, there was no Keshan disease in many Se deficiency villages. Conclusion Local Keshan disease prevails in Selenium deficiency district. However, Selenium deficiency is not the only factor, their might be multiple factors that can cause Keshan disease.
