回乳抑增颗粒对乳腺增生伴高泌乳素血症大鼠药效作用

摘要

目的 从血清激素水平和乳腺组织病理形态学角度,比较回乳抑增颗粒与回乳抑增原煎剂对乳腺增生伴高泌乳素血症大鼠的药效学作用.方法 将大鼠随机分成7组:正常对照组、模型对照组、回乳抑增颗粒组、回乳抑增原煎剂组、乳癖散结组、溴隐亭组和辅料组,各10只.除正常对照组外,其他各组制备乳腺增生伴高泌乳素血症模型.回乳抑增颗粒组给药剂量为17.22 g·kg-1·d-1,回乳抑增原煎剂组给药剂量为20.08 g·kg-1·d-1,乳癖散结组给药剂量为0.416 mg·kg-1·d-1,溴隐亭组给药剂量为0.393 mg·kg-1·d-1.均灌胃给药,每日1次,每次2 mL,连续30 d.显微镜观察大鼠乳腺组织病理形态学变化,酶联免疫吸附(ELISA)法测定大鼠泌乳素(PRL)、孕酮(P)、雌二醇(E2)含量.结果 回乳抑增颗粒组PRL(22.74±4.74) pg·mL-1,P(46.91±2.85) ng·mL-1,E2(99.96±9.61) pg·mL-1;回乳抑增原煎剂组PRL(28.41±6.37) pg·mL-1,P(43.91±4.17) ng·mL-1,E2(105.02±3.05) pg·mL-1;溴隐亭组PRL(23.58±4.10) pg·mL-1,P(45.99±2.95) ng·mL-1,E2(98.04±9.98) pg·mL-1.与模型对照组比较,上述3组PRL、E2明显下降,P明显上升(P<0.01),回乳抑增颗粒组、回乳抑增原煎剂组和溴隐亭组PRL、P、E2含量给药30 d后恢复正常水平,乳腺组织增生减轻.回乳抑增颗粒组和回乳抑增原煎剂组比较,回乳抑增原煎剂组为Ⅰ或Ⅱ级增生,回乳抑增颗粒组为0或Ⅰ级增生,回乳抑增颗粒对乳腺增生抑制作用优于回乳抑增原煎剂.%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 groups:normal 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.
