| 我国克山病、大骨节病的地理分布规律 我国克山病主要分布于黑龙江省到云南省、西藏东部一条东北—西南走向不连续的宽带内,称之为"病带"(图1).这个病带具有共同的特点:1.克山病主要分布在病带内的山丘地区,而病带内的一些大型现代冲积湖积平原则一般无克山病流行.病区分布的海拔高度也不同,总的趋势是纬度愈低分布愈高; 2.病区在气候上具有温暖和中度湿润的特点. |
| 英文摘要 |
| This article gives a brief summary based on authors' studies on environmental pathogeny of Keshan and Kaschin-beck diseases in recent years. In China there is an environmentally low selenium belt, which mainly covers the brown-drab soil series of temperate and warm temperate zones. The soil-plant-animal-human system in this belt shows a low selenium ecological cycle. Keshan and Kaschin-beck diseases have been investigated in some mountainous and hilly districts in that belt with disconnected tracts. Obvious negative relationship between incidence of Keshan and Kaschin-beck diseases and low selenium nutrition. Low selenium in human body is found coincident to geographically epide-miological rule of these endemic diseases.Keshan disease can be effectively prevented by using sodium selenite. It can also be used to cure or to prevent Kaschin-beck disease. |
