山东省克山病基本控制后的病情演变

The Changes of Keshan Disease's Condition in Shandong Province After Basic Control

为掌握山东省克山病1992年基本控制后的病情演变，选择具代表性的莒县和平邑两县，对近5年克山病发病情况、现存慢型克山病进行了调查，并对3～14岁易患人群1488例进行了全面检查重点调查，同时调查了内外环境硒及生活水平。结果显示近5年来慢型克山病累计发病率0．02／万，易患人群慢型克山病检出率0．13％，潜在型1．68％，现存慢型克山病患病率0．39％．无急型、亚急型克山病发病。病区居民发硒0．24～0．324mg／kg，人均收入750.0～1283.1元，人均口粮180．0～414．3kg。克山病病情处于基本控制后的稳定势态，病区居民生活水平较克山病高发年明显改善。

In order to understand the changes of Keshan disease's condition in Shandong province afterbasic control, Juxian county and Pingyi county were selected to investigate the prevalence condition of Keshandisease and the prevalence condition of Keshan disease in 1 488 cases of 3 to 14 year-old susceptible people forpresent 5 years. At same time selenium in and out environment was determined and life condition ofinhabitant was surveyed. The result showed that general incidence of chronic Keshan disease was 0. 02 per tenthousand and incidence of chronic Keshan disease and potential Keshan disease were separatly 0. 13 per centand 1. 68 per cent in 1 488 cases of susceptible peoole. Acute Keshan disease and subacute Keshan diseasewere not found. Selenium content of hair, wheat, maize and sweet potato was slightly high in Pingyi Liouyubut slightly low in Juxian Longshan. Economic income was from 750. 0 to 1 283. 5 yuans and total grain 180.0 to 414. 3 kilograms per man in inhabitant. So we think that life level of inhabitant in endemic area has beenimproved and Keshan disease's condition has been in stable state after basic control.
