Objectives To study the relationship between serum nitric oxide (NO and plasma cyclic guanosine monophosphate (cGMP) and prolonged bleeding after medical abortion. Methods A total of 120 women having received medical abortions at random were recruited and divided into two groups: the one (Group A,n=60) taking “Gong Fu Mixture(Uterus Recovering Mixture)” and the other (Group B,n=60) not taking it after abortion. On d 10, 20 and 30 after medical abortion, serum NO and plasma cGMP were tested before and after mifepristone administration and 10 d later by Gresis reaction method and radioimmunoassay respectively. Results NO concentration in serum and cGMP concentration in plasma decreased significantly after taking mifepristone given (P<0.05). Ten days later, the number of those with bleeding discontinuation in the group A was significantly greater than that in the group B (P<0.05). Serum NO level and plasma cGMP level in the group A decreased more significantly than those in the group B (P<0.05). Conclusion The slow decrease of serum NO and plasma cGMP is closely related to prolonged bleeding after medical abortion. “Gong Fu Mixture (uterus recovering mixture)” is effective in prevention and treatment of prolonged bleeding.
