Abstract:
Albino rats fed on crops from endemic and non-endemic districts of Ke-shan desease, were used in this experiment, which was studied by 85Zn tracer metabolic method after 8 weeks feeding. Uptake of 85Zn (ZnCl2) by blood, heart, liver, kidneys and brown adipose tissue were determined at 24 and 72 hours after injection of this tracer respectively, and its distribution was thoroughly examined. The results revealed that the uptake of 8aZn was higher in the groups fed on crops from endemic districts, particularly significant in liver, kidneys and brown adipose tissue. This may reflect the lacking or deficiency of zinc in the bodies.The regular differences of 85Zn between two groups were certainly related to the crops produced from endemic or aon-endemic districts. In other words, there should be some differences between crops from endemic and non-endemic areas. Thus more attention should be paid to the factors in endemic crops, which induced lacking or deficiency of zinc in the experimental animal and to its relationship with etiology of Keshan disease.
