Abstract:
OBJECTIVE:To study the effect of Typhae pollen decoction on isolated uterine smooth muscle(USM)contraction of rats at postconceptual stage. METHODS:16 Wistar rats at postconceptual stage were selected and USM strips were isolated. T. pollen decoction 0(blank control),2,4,8 and 12 mg(medicinal material)/ml were added respectively;the effects of T. pollen de-coction on USM strips contraction were observed,and mean tension,duration of contraction and frequency were measured and re-corded. The effects of T. pollen decoction on USM strips contraction were investigated after pretreatment of prostaglandin synthase inhibitor indometacin(1×10-7 mol/ml)and calcium channel blocker verapamil(1×10-7 mol/ml);USM tension,duration of contrac-tion and frequency were measured and recorded. RESULTS:Compared with blank control group,T. pollen decoction 4,8 and 12 mg(medicinal material)/ml could increase USM tension,duration of contraction and frequency(P<0.05);after added verapamil and indometacin,T. pollen decoction decreased USM tension,shortened duration of contraction and decreased frequency (P<0.05). CONCLUSIONS:T. pollen decoction can strengthen USM strips contraction,and the effect is inhibited by prostaglandin syn-thase inhibitor and calcium channel blocker.
