Abstract:
Objective To investigate the effect of the optimal prescription of huiru yizeng on rats with hyperplasia of mammary gland and hyperprolactinemia. Methods Fifty-six female Wistar rats were randomly divided into 7 groups (n=8), including normal control group, model control group, sodium chloride group, bromocriptin group, rupi sanjie group, the original prescription group and optimizing prescription group. Rat model of mammary gland hyperplasia with hyperprolactinemia was replicated in 6 groups but not the normal control group. The successfully established experimental rats were given corresponding drugs by intragastric gavage. After 30 days, the levels of the estradiol, progesterone, and prolactin were detected, and the pathomrphology of glandular tissue was observed. Results Prolactin levels of model control group, the original prescription group and optimize prescription group were (69.47 ±6.08), (53.13 ±10.59), and (28.41 ±6.37) pg·mL-1, respectively . Compared with that in the model control group, the contents of prolactin in both the optimal prescription group and the original prescription group were reduced, but the optimal prescription group was better (P<0. 01). In the original prescription group, the lobules of mammary gland showed a few of hyperplasia, the individual alveoli and duct showed a slight hyperplasia, and a small amount of secretions was found in the duct. The degree of the hyperplasia was alleviated in the optimal prescription group similar to that observed in the normal control group, which showed that there was no hyperplasia in the lobules of mammary gland or no secretions in the duct. Conclusion The therapeutic effects of the optimal prescription are much better than the original prescription, which can effectively lower the level of prolactin, adjust the balance among the prolactin , estrogen and progesterone, and alleviate the pathological hyperplasia of mammary glands in the model rats.
