RESUMO
<p><b>OBJECTIVE</b>To study the protective effect of purariae isoflavone on apoptosis cells of atrophic nasal mucosas in ovariectomized rats.</p><p><b>METHOD</b>60 rats were divided into four groups as control, ovariectomized, ovariectomized + nylestriol (O + N) and ovariectomized + purariae isoflavone (O + P), each with 15 rats. Earlier apotosis cells of mucosas taken from nasal septum were measured with flow cytometry.</p><p><b>RESULT</b>Compared with control group, and the number of apoptosis cells of mucosas increased after being ovariectomized,and the number of apoptosis cells of mucosas in O + N and O + D group didn't change.</p><p><b>CONCLUSION</b>Nylestriol and purariae isoflavone might have effects on protecting cells of mucosas from lacking of estrogen by decreasing apoptosis cells in ovariectomized rats.</p>

<p><b>OBJECTIVE</b>To study the effect of purariae isoflavone on estrogen level in ovariectomized rats.</p><p><b>METHOD</b>80 rats were divided into four groups randomly, every group with 20 rats: 1. Control group; 2. Normal + purariae isoflavone group; 3. Ovariectomized group; 4. Ovariectomized + purariae isoflavone group. Estrogen level and gonadotropin-releasing hormone level of all rats were measured.</p><p><b>RESULT</b>Thirty days after being ovariectomized, E2, E3 level was significantly lower than that of the first group(P < 0.05). But Testerone, FSH, LH, PRL and GH increased(P < 0.05). After being gastrogavaged with purariae-isolfavone for thirty days, Estrogen level and gonadotropin-relasing hormone level of the second group were significantly lower in various degree than those of normal control group (P < 0.05). But in ovariectomized rats, the estrogen level was recovered (P > 0.05). The gonadotropin-releasing hormone level was increased (P < 0.05).</p><p><b>CONCLUSION</b>Purariae-isoflavone can increase estrogen level to normal in ovariectomized rats by way of increasing the level of gonadotropin-releasing hormone. In normal rats, it has anti-estrogen effect.</p>
