乳宁霜对乳腺增生病大鼠血液流变学及乳房微循环的影响

目的通过观察乳宁霜对乳腺增生病大鼠血液流变学及乳房微循环的影响,探讨乳宁霜治疗乳腺增生病的机理。方法选用SPF级雌性Wistar大鼠70只,随机分为空白对照组、单纯疾病模型组、三苯氧胺软膏组、散结乳癖贴膏组及乳宁霜大、中、小剂量组,每组10只,采用苯甲酸雌二醇和黄体酮建立乳腺增生动物模型,分别涂抹三苯氧胺软膏、散结乳癖贴膏、不同剂量乳宁霜予以治疗,空白对照组、单纯疾病模型组不用药。观察乳腺增生病大鼠血液流变学及乳房微循环变化。结果单纯疾病模型组与空白对照组比较,其全血粘度、血浆粘度、红细胞压积、纤维蛋白原显著增加(P<0.05或P<0.01),乳房微循环灌注量减少(P<0.01);乳宁霜各剂量组大鼠全血粘度、血浆粘度、血沉和压积及微循环灌注量均基本回复到空白对照组正常水平,与模型对照组比较,差异显著(P<0.05或P<0.01)。结论乳宁霜可改变乳腺增生病大鼠的血液流变性,增加乳房的微循环灌注量,是其治疗和预防乳腺增生病的机理之一。

Effect of Runingshuang on the Blood Rheology and Mammary Microcirculation of Rat with Cyclomastopathy

Objective To research the mechanism of treating cyclomastopathy with Runingshuang by measuring the blood rheology and mammary microcirculation. Methods 70 female Wistar rats of SPF were randomly divided into seven groups:the blank control group, the pathologic model group, the comparative group of tamoxifen ointment, the comparative group of Sanjierupi Glue, three remedial groups with large, middle and small dosage of Runingshuang. Pathologic model of mammary hyperplasia was made by injecting estrogen and progesterone. Except the former two groups, each group was treated with different drugs. The blood rheology and mammary microcirculation were measured after 30 days. Results Compared with the blank control group, blood viscosity, plasma viscosity, packed cell volume and the fibrinogen of the pathologic model group increased evidently (P <0.05 or P <0.01), mammary microcirculation perfusion decreased evidently (P <0.01). Blood viscosity, plasma viscosity, packed cell volume and the fibrinogen of three Runingshuang groups got back to the normal level on the whole, and had significant difference compared with the pathologic model group (P <0.05 or P <0.01). Conclusion Runingshuang could cure and prevent cyclomastopathy by influencing blood rheology and increasing perfusion of mammary microcirculation.
