[Clinical and experimental study on the ovulation promoting effect of yangjing decoction]
Objective:
To observe the effect of Yangjing Decoction (YJD) to promote ovulation and to explore its mechanism.
Methods:
The clinical effect of YJD in treating patients of functional non-ovulation and changes of gonadotropic hormone, sex hormone and diameter of main follicle before and after treatment were observed. In experimental study, the influence of YJD on monoamine neurotransmitter of hypothalamus, endorphin (beta-EOP), serum sex hormone, trace element, endometrium and histomorphology of ovary were observed.
Results:
In the 36 patients observed clinically, the ovulation rate was 61.1%, the serum contents of follicular stimulation hormone (FSH), luteinizing hormone (LH) and estradiol (E2) increased and the diameter of main follicle enlarged significantly after treatment (P < 0.01, P < 0.001). The experimental study showed that the totals of follicle at different levels, the corpus luteum and the proportion of superior follicle in ovary were improved obviously in the YJD group as compared with those in the control group. After YJD treatment the hypothalamus contents of monoamine neurotransmitter, including norepinephrine (NE) and dopamine (DA) increased, the 5-hydroxytryptamine (5-HT) 5-hydroxyindoleaceticacid (5-HIAA) and beta-EOP decreased significantly, and the NE/DA ratio and NE/5-HT ratio elevated obviously (P < 0.05, P < 0.001). The serum levels of E2, P and trace elements, including Zn, Cu and Fe increased significantly (P < 0.05, P < 0.01).
Conclusion:
YJD is an effective recipe in promoting ovulation, the effect may be achieved through the multi-linked, multi-systemetic synthetic effect of hypothalamus, hypophysis and ovary, etc.
