归参胶囊对大鼠乳腺增生及脾脏T淋巴细胞亚群的影响

目的:探讨归参胶囊(当归、丹参等)对大鼠乳腺增生及脾脏T淋巴细胞亚群影响.方法:应用ip苯甲酸雌二醇复制大鼠乳腺增生模型,同时应用高中低三个归参胶囊处理.用药30 d后处死大鼠,取乳腺作组织切片观察.同时剖腹取脾脏,剪碎,研磨后,用无钙镁的hank's液制备成单细胞悬液,应用流式细胞仪双色法测定CD3 、CD4 、CD8 百分比及CD4 /Cda 比值.结果:模型组大鼠体重增长缓慢,乳房肿大,乳腺组织增生明显,并且CD3 、CD4 、CD4 /CD8 值显著降低,而灌服归参胶囊的大鼠能不同程度抑制大鼠乳房肿大和乳腺增生,并能明显提高CD3 、CD4 百分比及CD4 /CD8 比值.结论:归参胶囊具有抑制乳腺增生,增强机体免疫力,调节细胞免疫的功能.

Effect of Guishen Capsule on mastoplasia and T-lymphocyte subsets of spleen in rats

AIM: To investigate the effect of Guishen Capsule(Radix Angelicae Sinesis,Radix et Rhizoma Salivae Miltiorrhizae,etc) on mastoplasia and T-lymphocyte subsets of spleen in rats. METHODS: The model of mastoplasia was induced by benzoate estradiol intraperitoneal injection in SD female rats.The model rats were treated with low,middle and high dosages of Guishen Capsule,respectively.All rats were killed after 30 days,the tissue of second pair of mammary glands were observed.At the same time,the spleens were taken out for preparing single cells suspension.The ratio of CD~ _3,CD~ _4,CD~ _8,CD~ _4/CD~ _8 of splenic T-lymphocytes were determined by flow cytometry(FCM). RESULTS: Compared with normal group,the growth of weight was slow in model group,and its breast was swollen,and proliferation was obvious in mammary gland tissue,the ratio of CD~ _3,CD~ _4,CD~ _4/CD~ _8 reduced significantly in model group. Guishen Capsule could inhibit the breast swelling and mammary gland hyperplasia.It also could increase ratio CD~ _3,CD~ _4,CD~ _4/CD~ _8 of splenic T-lymphocytes remarkably. CONCLUSION: Guishen Capsule can inhibit mammary gland hyperplasia.It also has the function of immunologic enhancement and cellular immune regulation.
