Abstract:
Observations were conducted on 11 kinds of tissues and organs(brown adipose tissue, thymus gland, blood, heart, lungs, muscle, bone, kidneys, spleen, liver, and intestine) in experimental animals, which were fed on crops from endemic areas of Keshan disease and non-endemic areas for 8-13 weeks. The absorption and distribution of 75Se (Na2 SeO3) in above tissue and organs were studied. Results revealed that the absorption of Na2-SeO3 in experimental group fed on crops from endemic area was higher than control group fed on crops from non-endemic area. The gradient of distribution of 75Se in various organs was regular: The highest absorption was in kidneys, the lesser was in liver, spleen and thyrnus, the least was in muscle, heart and bones.In one week observation, the contents of 75Se changed as time passed, but the fluctuating changes of the two groups were different.The regular differences of 75Se absorption as above, revealed a distinction between endemic and non-endemic crops. Under the influences of the crops on experimental animals, there appeared more or less a condition of selenium deficiency, which proved that the soil-water-food chain had apparently influenced the selenium metabolism of the organisms.
