The study was conducted to evaluate the effect of intervention of skim milk based functional drink supplemented with 100 mg of soy isoflavone and 8 mg of Zn-sulfate (susumeno) on serum estradiol and thymulin hormones levels of permenopausal women. After 2 month of intervention, the estradiol levels did not change, and the levels were in the range of 39,16 – 41,99 pg/ml. However the thymulin hormone levels increased significantly from 2,37 Ã‚Âµg/ml to 3,31 Ã‚Âµg/ml. Increase in thymulin levels shows that the disfuction of immune system of premenopausal could be improved by the functional drink.
Key words : Estradiol, thymulin, soy isoflavone, Zn, premenopausal women.
