Objective:
To investigate the effect of Yi Fu Ning Soft Gelatin Capsules (YFN) on reproductive endocrine-immune function of ovariectomized rats.
Methods:
60 3-month old female Sprague-Dawley rats were used, 50 of them were ovariectomized and randomly divided into 5 groups: ovariectomizy (OVX) group, OVX with diethylstilbestrol tablets (DT) group, OVX with YFN (high dose, middle dose and low dose) group. The others were sham-operated group. The rats were administrated initially in the 4th week after the operation. After drugs had been given for 12 weeks the rats were sacrificed, blood serum hormone, IL-2 content and T lymphocyte subpopulation were detected with methods radioimmunoassay and flow cytometry (FCM).
Results:
(1) Compared with sham group, the level of serum E2, Te and P significantly decreased (P < 0.01), FSH, LH content significantly increased; Blood T lymphocyte subpopulation CD3+ cells, CD4+ cells and CD4+/CD8+ ratio significantly decreased, serum IL-2 content also significantly decreased (P < 0.01). (2) Compared with model group, after treated by YFN, the level of serum E2 and P significantly increased (P < 0.01), serum FSH and LH content significantly decreased; T lymphocyte subpopulation CD3+ cells, CD4+ cells and CD4+/CD8+ ratio were improved significantly and serum interleukin-2 (IL-2) content increased significantly.
Conclusion:
YFN can increase serum sexual hormone content,reduce the level of FSH and LH, and improve imbalanced T lymphocyte subpopulation, stimulate IL-2 excretion, which means YFN can regulate inordinate reproductive endocrine-immune network in ovariectomized rats.
