ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of different concentration extract from Shenghua decoction on contractile activity of the uterine smooth muscle isolated from normal, estrogen-treated and postpartum mice.</p><p><b>METHOD</b>Medlab/4 s vital signal recorder was used to measure the effects of extract from Shenghua decoction (3-12 mg x mL(-1)) on contractile amplitude and frequency of the isolated uterus from normal, estrogen-treated and postpartum mice.</p><p><b>RESULT</b>Shenghua decoction extract (3-12 mg x mL(-1)) significantly decreased the contractile activity of the mouse isolated uterus in normal non-pregnancy and postpartum, but significantly increased that of the mouse isolated uterus treated with estrogen, and didn't show significant concentration-response relationship.</p><p><b>CONCLUSION</b>The effects of Shenghua decoction extract on contractile activity of mouse-isolated uterus treated with estrogen cannot represent the pharmacological effects on that of in normal non-pregnancy and postpartum uterus.</p>
