【Abstract】 The relationship between zinc absorption microconstant K21/K12 ratio and zinc absorption rate has been studied by a two-compartmental model in perfused in situ rat jejunum. It is found that correlation coefficients between K21/K12 ratioes and zinc absorption rates in normal control group, vitamin D-deficfent group, supplement 5000 IU/kg vitamin D3 group and supplement of 30000 IU/kg vitamin D3 group, diabetes group and insulin-treatment group are 0.74-0.92. The result shows that the relationship between K21/K12 ratio and absorption rate is not influenced by various factors of animal and treatments, and the ratio can be used in the study of zinc absorption mechanism.更多还原
