Effect of Huiru Yizeng Granules on Hhyperplasia of Mammary Glandsin Rats with Hhyperprolactinemia / 医药导报

ABSTRACT

Objective To compare the effects of Huiru Yizeng granules Huiru yizeng original decoctin on hyperplasia of mammary glands with hyperprolactinemia in serum and pathological morphology of mammary glands tissue.Methods Seventy rats were randomly divided into 7 groupsnormal control group,model control group,Huiru yizeng granules group,Huiru yizeng original decoctin group,Rubisanjie group,bromocriptine group and accessories group.After sucessfully modeling hyperplasia of mammary glandsin rats with hyperprolactinemia,Huiru yizeng granules group was administrated 17.22 g·kg-1·d-1,Huiru yizeng original decoctin group was administrated 20.08 g·kg-1·d-1,Rubi sanjie group was administrated 0.416 mg·kg-1·d-1,bromocriptine group was administrated 0.393 mg·kg-1·d-1.These groups were intragastric administration 2 mL every day for 30 consecutive days.The morphology of pathological tissue in mammary gland was observed by microscope.The levels of prolactin(PRL),progesterone(P),estradiol(E2) were determined by ELISA kit.Results Compared with the model group,Huiru yizeng granules group[PRL=(22.74±4.74) pg·mL-1,P=(46.91±2.85) ng·mL-1,E2=(99.96±9.61) pg·mL-1],Huiru yizeng original decoction group[PRL=(28.41±6.37) pg·mL-1,P=(43.91±4.17) ng·mL-1,E2=(105.02±3.05) pg·mL-1] and bromocriptine group[PRL=(23.58±4.10) pg·mL-1,P=(45.99±2.95) ng·mL-1,E2=(98.04±9.98) pg·mL-1]showed significant decrease in PRL,E2 levels,obvious increase in P(P<0.01).In Huiru yizeng granules group,Huiru yizeng original decoction group and bromocriptine group,PRL,P,and E2 returned to normal level after 30 days,and hyperplasia of mammary glands tissue had great ease.Huiru yizeng original decoction group was Ⅰ to Ⅱ hyperplasia,and Huiru yizeng granules group was 0 or Ⅰ hyperplasia.Compared with each other,the effect of Huiru yizeng granules on the mammary gland proliferation inhibition was superior to Huiru yizeng original decoction group.Conclusion On the treatment of hyperplasia of mammary glands and hyperprolactinemia,Huiru yizeng granules were better than Huiru yizeng original decoction.
