RESUMO
<p><b>OBJECTIVE</b>To study the therapeutic mechanism of Kunyining (KYN) on the climacteric syndrome and provide the pharmacodynamic basis.</p><p><b>METHOD</b>Ovariectomized rats were used as model to observe the effect of KYN on weight and the index of the organ of OVX rats. The concentration of E2, FSH, LH, PRL, BGP and IL-2 in serum were measured by competitive radio-immunological methods.</p><p><b>RESULT</b>KYN could obviously increase the index of uterus and adrenal gland in OVX rats, and enhance the contents of E2, IL-2 and BGP. The level of FSH, LH, PRL in serum were decreased.</p><p><b>CONCLUSION</b>KYN can regulate beneficially the unbalanced reproductive endocrine-immune network, which is the pharmacological basis of KYN treating climacteric syndrome.</p>
