daidzein sulfonate groups of mice the prostate wet weight, prostatic index, and sex hormone effects. Results 3 '
daidzein sulfonate on testosterone-induced prostatic
hyperplasia has significant antagonistic effect; the same time can be significantly reduced serum T, E2, T/E2 content.
Conclusion 3 '
daidzein sulfonate in mice significantly inhibited prostatic hyperplasia, lower serum T, E2, T/E2 content, and thus play a role in inhibiting prostatic hyperplasia in mice.

Abstract: ObjectiveTo study the effects of 3 '
daidzein sulfonate sodium on Benign Prostatic Hyperplasia in mice and sexual hormone homeostasis.MethodsModels of Benign Prostatic Hyperplasia were established by hypodermic injection testosterone propionate in mice.Observe the prostate glandular wet weights, indexes of prostate glandular and sexual hormone level in control group, model group, low dose 3 '

daidzein sulfonate sodium apparently inhibited Benign Prostatic Hyperplasia in mice induced by testosterone propionate, obviously decreased the content of T, E2 and T/E2 in serum of mice, control the sexual hormone
homeostasis.Conclusion3 '-daidzein sulfonate sodium can
apparently inhibit Benign Prostatic Hyperplasia in mice induced by testosterone propionate can obviously decrease the content of serum testosterone (T) , serum estradiol (E2) and T/E2 in serum of mice, control the sexual hormone homeostasis.

3'-daidzein sulfonate (3 '
daidzein sulfonate sodium DSS) is the main active ingredient of Chinese medicine puerarin daidzein for structural modification and the modification of newly
synthesized strong water-soluble substances. Traditional
Chinese Medicine of puerarin puerarin and daidzein are more studies on pharmacological effect. We found that daidzein with anti-arrhythmia, vascular smooth muscle relaxation, inhibit cholecystokinin, hypoxia tolerance, immune enhancement and the role of local anesthesia [1 ~ 5]; It was also reported that daidzein, have antioxidant properties ; right EDHF induced by the long-term male rat endothelium has relaxing effects ; on in vitro vascular relaxation effects are . However, daidzein did not dissolve in water, in the presence of clinical bioavailability of low dose disadvantages such as large and markedly slow. The 3 '

the mouse model of experimental study of benign prostatic hyperplasia [10,11]. 3 '
daidzein sulfonate (C15H907SNa, white crystalline powder). From Shenyang Pharmaceutical University, providing plant-based
teaching and research, purity above 97%. Is reported that its
benign prostatic hyperplasia in mice and regulation of sex hormone balancing effects.
1 Materials and methods
1.1 Drugs and reagents 3 '
Daidzein Sulfonate: from Shenyang Pharmaceutical University, providing plant-based teaching and research.
Diluted with saline before the experiment to the desired concentration, pH adjusted to 7.0 with NaHCO3 back. Testosterone Propionate Injection: Shanghai GM Pharmaceutical Co., Ltd. manufacture, batch number: 030,519. The forefront of
health: Zhejiang CONBA Group Pharmaceutical Co., Ltd. manufacture, batch number: 050.65 thousand.
1.2 Animals Adult male mice, from Jiangxi Medical College Laboratory Animal Center, Animal qualified证号:2006-075. Free
mice in each group feeding, drinking water.
1.3 Packet 40 adult male mice were randomly divided into five groups (n = 8), the control group, model group, the prostate group, small dose group, high-dose drug group.
1.4 Preparation of benign prostatic hyperplasia model
mice by normal diet to adapt to 1 week after the experiment,
the control group given peanut oil a day 0.1 ml / only, the other groups were injected subcutaneously daily testosterone propionate 5 mg / (kg * d), continuous 12 d.Prostate group fed at the same time every day5 g/(kg*d)Prostate treatment group were fed daily0.02,0.04 g/(kg*d)The3' daidzein sulfonate.
The first 13 days, the mice were killed, weighed prostate tissue obtained by prostate weight, prostatic index.
1.5 Mice impact of changes in serum sex hormone
administration methods ibid., 13 days, mice were fasting blood serum by radioimmunoassay T, E2 levels.

Benign prostatic hyperplasia and prostatitis is a common disease of male urinary system, China's current patients with
varying degrees of prostate hyperplasia approximately 8000 million people. The incidence of prostatitis in elderly men more than 50% of the current clinical treatment of benign
prostatic hyperplasia and prostatitis lack of effective drugs,
the general surgery and drug treatment. Surgical treatment is better, but poor patient acceptance, there are more side-
effects of Western medicine. Therefore, the search of a good preventive medicine is of great significance. 3 '
daidzein sulfonate is the main active ingredient of Chinese medicine puerarin daidzein for structural modification and the modification of newly synthesized strong water-soluble
substances can be made into a variety of formulations.In this paper, animal models of prostate3'Daidzein Sulfonate
pharmacodynamic study. The results show that: 3 'daidzein sulfonate on testosterone-induced prostatic hyperplasia has
significantly inhibited; can significantly reduce the mouse prostate and prostate wet weight index significantly decreased
serum T, E2 , T/E2 content, regulate hormone balance in mice. 3 'daidzein sulfonate inhibit the role of benign prostatic hyperplasia in mice may be by decreasing T, E2 levels, regulate hormone balance in mice to achieve. The exact mechanism of action remains to be further studied.
