龙血竭对子宫内膜异位症模型大鼠的影响∗

摘要

目的：观察龙血竭对子宫内膜异位模型大鼠的治疗作用。方法随机选取雌性大鼠10只作为空白对照组,50只复制血瘀子宫内膜异位症模型大鼠按随机数字表法分为5组：龙血竭大、中、小剂量组,桂枝茯苓组和模型对照组,每组10只。龙血竭大、中、小剂量组大鼠灌胃给予不同剂量龙血竭混悬液(0.50,0.25,0.12 g.kg－1.d－1),桂枝茯苓组给予桂枝茯苓胶囊(0.25 g.kg－1.d－1),模型对照组和空白对照组给予等容量0.5％羧甲纤维素钠溶液。给药3周,处死大鼠,计量异位组织体积、质量,血液流变仪检测血液黏度,酶联免疫吸附法检测血清中雌二醇、孕酮水平,聚合酶链反应法测定异位组织中基质金属蛋白酶-2( MMP-2)表达。结果大、中、小剂量龙血竭明显减少异位组织的体积和质量,抑制异位组织中MMP-2mRNA表达；大、中剂量龙血竭可以明显降低模型大鼠血浆中切和低切黏度,但龙血竭对于血清中雌二醇和孕酮的水平无明显影响。结论龙血竭降低血液黏度,抑制异位组织MMP-2表达,可以用于血瘀子宫内膜异位症的治疗。%Objective To investigate the therapeutical effect of Resina draconis. on endometriosis rat model. Methods Totally, 60 adult rats were selected and divided into blank control group( n=10) and blood stasis endometriosis model group( n=50 ) . The blood stasis endometriosis model group was randomly divided into 5 groups after modeling: the Resina draconis. high-, medium-, and low-dose group, Guizhi Fuling group and model control group, 10 rats in each group.The Resina draconis. at 0.50, 0.25 and 0.12 g.kg-1 .d-1 was administered to the rats in the Resina draconis. high-, medium-, and low-dose groups, Guizhi Fuling capsule at 0. 25 g . kg-1 . d-1 to those in Guizhi Fuling group, and the same volume of 0. 5% sodium carboxyl methyl cellulose solution to those in model control group and blank control group. All treatments lasted for 3 weeks.At the end of the treatment, the rats were sacrificed;the volume and weight of ectopic tissue were measured. The blood viscosity was detected with blood rheometer.The concentration of estradiol and progesterone was detected using enzyme-linked immune sorbent assay.The matrix metalloprotein-2 expression in ectopic tissues was determined by RT-PCR. Results High, medium and low dose Resina draconis. significantly reduced the volume and weight of the ectopic tissue, and inhibited MMP-2 expression in ectopic tissues.High-, medium-dose Resina draconis. significantly reduced plasma cutting middle and low shear viscosity of the rats.But the Resina draconis. had no obvious effect on serum estradiol and progesterone concentration. Conclusion Resina draconis. reduces blood viscosity and inhibits MMP-2 expression, which can be used for the treatment of blood stasis type of endometriosis.
