仙附温阳通络饮对血栓闭塞性脉管炎模型大鼠抗中性粒细胞抗体相关抗原的影响

Effects of Xianfu Wenyang Tongluo Drink on ANCA Associated Antigen in Thromboangiitis Obliterans Rat Models

目的观察仙附温阳通络饮对血栓闭塞性脉管炎(TAO)模型大鼠抗中性粒细胞抗体(ANCA)相关抗原的影响,探讨其作用机制。方法 SPF级Wistar雄性成年大鼠72只,随机分为假手术组、模型组、脉络宁颗粒组及仙附温阳通络饮低、中、高剂量组。以股动脉注射月桂酸钠溶液方法造模。造模后次日开始给药,假手术组、模型组给予蒸馏水灌胃,其他各组给予相应药物灌胃。给药15 d后取材,采用紫外分光光度法检测血清中髓过氧化物酶(MPO)活性,免疫组化法检测股动脉及周围组织中蛋白酶3(PR3)和溶酶体相关膜蛋白-2(LAMP-2)蛋白表达。结果与假手术组比较,模型组大鼠血清中MPO活性及PR3、LAMP-2蛋白表达均升高;与模型组比较,各给药组MPO活性及PR3、LAMP-2蛋白表达降低,其中仙附温阳通络饮中剂量组下降最明显。结论仙附温阳通络饮可能通过降低ANCA相关抗原水平,进一步抑制体液免疫功能亢进。

Objective To observe the effects of Xianfu Wenyang Tongluo Drink {XFWYTLD） on ANCA associated antigen in rats with thromboangiitis obliterans; To discuss its mechanism. Methods Totally 72 SPF male Wistar rats were randomized into sham-operation group, model group, Mailuoning Granule group and XFWYTLD low, medium, and high dose groups. Method of femoral artery injecting sodiumLaurate was used to duplicate models. From the second day after modeling, the rats in sham-operation group and model group were fed with distilled water, while other groups received garage with relevant medicine. 15 days later, the activity of MPO in serum was detected through the method of ultraviolet spectrophotometry; the protein expressions of PR3 and LAMP-2 in femoral artery and the surrounding tissues were detected through the method of immunohistochemisty. Results Compared with sham-operation group, the activity of MPO in serum and the protein expressions of PR3 and LAMP-2 in rats of model group were significantly higher; Compared with model group, the activity of MPO in serum and the protein expressions of PR3 and LAMP-2 in rats of all medication administration groups decreased, among which the XFWYTLD medium dose group showed the most obvious decrease. Conclusion XFWYTLD may lower levels of ANCA associated antigen, and further inhibit humoral immune function.
