| 目的 为验证青心酮对子宫-胎盘血液循环的影响。方法 应用彩色多普勒观察正常妊娠家兔脐动脉血流速度波形,在注射青心酮2.5mg/kg,5mg/kg,10mg/kg三个剂量组用药前、后的变化。于用药前、用药后10min、30min、60min监测兔崽脐动脉血流速度波形。结果 其收缩期峰值流速略有下降,舒张末期流速升高,S/D比值,阻
力指数(RI),搏动指数(PI)在三个剂量组均较用药前降低。结论 青心酮能有效改善妊娠家兔子宫-胎盘血液循环,降低脐动脉血管阻力。 |

| Objective To verify the influence of 3,4-Dihydroxyacetophenone (3,4-DHAP) on blood circulation of uterus and placenta. Methods Twenty normal pregnant rabbits were divided into three groups.Group Ⅰ was given 3,4-DHAP injection in a dose of 2.5mg/kg,group Ⅱ was given 5mg/kg,group Ⅲ was given 10mg/kg.Umbilical artery blood flowing waves were recorded before injection,then the waves were recorded after 10,30 and 30 minutes intervals. Results Peak velocity of umbilical artery in systole desend a little,while end diastole velocity elevated.In the three groups,S/D ratio RI and PI decreased after 3,4-DHAP injection. Conclusion 3,4-DHAP is an effective drug to improve blood circulation of uterus and placenta of pregnant rabbits and can decrease the umbilical artery resistance. |
