Compare with positive controls: ◇ P<0.05;
Compare with small dose group: △ P<0.05, △ △ P<0.01
As can be seen from Table 3, normal pregnancy group rat uterus smooth muscle thickness significantly reduces than the blank group, and this is owing to due to embryo's the compressing, be a kind of normal physiological reaction.The uterine smooth muscle thickness of model group significantly reduces than the blank group.With model group relatively: in positive controls, the medicine of the present invention, the uterine smooth muscle thickness of heavy dose of group obviously increases, and the small dose group there was no significant difference.Between three dosage groups relatively: in, heavy dose of group is apparently higher than small dose group, and compare between heavy dose of group and the middle dosage group, though the trend of increase is arranged, there was no significant difference.
Artery and vein external caliber area significantly increases than the blank group in the model group flesh layer.With model group relatively: in the medicine of the present invention, artery and vein external caliber area all obviously reduces in heavy dose of group flesh layer; The arteries bore area of positive controls obviously reduces, though and vein has the trend of reduction, there was no significant difference; Small dose group is there was no significant difference then.Between three dosage groups relatively: in, heavy dose of group is starkly lower than small dose group, and there was no significant difference between heavy dose of group and the middle dosage group.
Above result shows: in the medicine of the present invention, heavy dose can make rat medicine stream back metrorrhagia amount significantly reduce, promote the involution of uterus, thereby reach the effect of curative stream back metrorrhagia; In addition, medicine of the present invention can also messenger drug in the stream rat uterus mesentery, flesh layer artery and vein external caliber area significantly dwindle, and the flesh layer thickness is obviously increased.This illustrates that this medicine can impel the contraction of uterine vascular, and the flesh layer is thickened become fine and close.
The present invention is described according to preferred embodiment.Should be understood that the description of front and embodiment are just to illustrating the present invention.Under prerequisite without departing from the spirit and scope of the present invention, those skilled in the art can design multiple alternative of the present invention and improvement project, and it all should be understood to be within protection scope of the present invention.
