Abstract:
Objective To observe the effect of soy isoflavones on incretion of female rats. Methods 42 fe-male rots of 12 weeks old were divided into 3 groups at random. Low dose group were perfused with 40mg · kg-1·d-1 into stomach per day;high dose group were perfused with 80mg·kg-1·d-1 into stomach per day;control group were perfused with physiological saline into stomach. After 14 days,collected blood via jugular vein and tested 4 inde-xes-FSH, LH,E2 and P with chemoluminescence method. Results In 3 groups of soy isoflavones low doee group,soy isoflavones high dose group and control group,FSH were (0.13±0.021) mIu/ml, (0.12±0.018) mIu/ml, (0.15 ±0.024) mIu/ml respectively; LH were (0.17±0.032) mIu/ml, (0.15±0.043) mIu/ml, (0.18±0.047) mIu/ml respectively, which has no obvious differences (P > 0.05) ; E2 were (0.09±0.03) nmol/L, (0.03±0.03) nmol/L, (0.12±0.04) nmol/L respectively; P were (1.43±0.27) ng/ml, (2.82±0.37) ng/ml, (0.67±0.56) ng/ml re-spectivdy. Compare those 3 groups, E2 activeness of soy isoflavones group decreased obviously; but P activeness of soy isoflavones group increased obviously. Conclusion Soy isoflavones has no obvious effect on hypophysis hormone of rat, but the soy isoflavones of different dosages may measure the secretion of female rat ovary hormones by estrogen ac-tivity and antiestrogen activity.
