RESUMO

<p><b>OBJECTIVE</b>To study the antagonistic effect of 3'-daidzein sulfonate sodium (DSS) on benign prostatic hyperplasia (BPH) and its possible mechanism.</p><p><b>METHODS</b>Forty healthy mice were randomly divided into five groups: a normal control group without any treatment, a model group of BPH treated by subcutaneous injection of testosterone propionate, a positive control group with the BPH procedure treated by Qianliekang, a 20 mg/(kg x d) DSS group with the BPH procedure and a 40 mg/(kg x d) DSS group with the BPH procedure. After 12 days of the above treatments, the mice were sacrificed for measurement of the prostate glandular wet weight, the index of prostate gland (PI), the morphological changes of prostate gland by light microscopy and the contents of testosterone and estradiol in the serum.</p><p><b>RESULTS</b>The prostate wet weight and PI decreased dose-dependently after DSS treatment for 12 days compared with the BPH model group (P < 0.05 or P < 0.01). The hyperplastic epithelioglandular papilla waned and even disappeared in the DSS treated groups under the light microscope, the epithelial cells became cubical or flat. The effect of DSS at 40 mg/(kg x d) was similar to that of the positive anti-BPH drug Qianliekang. DSS reduced the serum testosterone, estradiol contents and the T/E2 ratio (P < 0.05 or P < 0.01).</p><p><b>CONCLUSION</b>DSS has significant antagonistic effect on BPH induced by testosterone propionate in mice, which may involve its regulatory action on the sex hormone balance.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the effect of Daidzein on Antiarrhythmia.</p><p><b>METHOD</b>The conventional antiarrhythmia methods were used.</p><p><b>RESULT</b>Daidzein was remarkedly effective in preventing ventricular fibrillation induced by chloroform in mice and arrhythmia induced by aconitine in rats. The arrhythmia induced by adrenalin in rabbits was antagonized by Daidzein and it could obviously inhibit the action potential amplitude of isolated sciatic nerves in toads. And it could also prevent ventricular fibrillation induced by calcium chloride in rats, and obviously reduce the death rate of rats. Its anti-arrhythmic effect was dose-dependent.</p><p><b>CONCLUSION</b>Daidzein has obvious protective effect on drug-induced arrhythmia, which may be related to its inhibition of Na+ or Ca2+ influx and its blocking beta-adrenergic receptor.</p>
