【摘要】 第一部分SLE小鼠模型的建立目的:探讨腹腔注射细菌脂多糖(LPS)制造SLE小鼠模型的最佳剂量。方法:80只小鼠随机分为4组,分别腹腔注射LPS 5 mg·kg - 1、2.5 mg·kg - 1和1.25 mg·kg - 1和生理盐水。结果:腹腔注射LPS 5 mg·kg - 1、2.5 mg·kg - 1组动物肾脏病理改变符合SLE病理特点,动物24小时尿蛋白含量、血清ANA的滴度、肾脏免疫复合物光密度均明显升高,而腹腔注射LPS 5 mg·kg - 1组动物死亡率明显升高。结果:腹腔注射LPS 5 mg·kg- 1、2.5 mg·kg - 1均能制造出良好的狼疮性肾炎模型,而腹腔注射LPS 5 mg·kg- 1动物死亡率高。第二步分中西医结合治疗对SLE模型鼠疗效观察目的:探讨中西医结合治疗对SLE模型鼠的疗效。方法:120只小鼠腹腔注射2.5 mg·kg - 1制造SLE模型鼠,随机分为6组,分别给予蒸馏水、中药清热解毒补肾方、强的松、环磷酰胺、清热解毒补肾方+强的松、清热解毒补肾方+环磷酰胺在造模的同时灌胃治疗15天。结果:与对照组相比,各治疗组动物死亡率、24小时尿蛋白含量、血清ANA的滴度、肾小球免疫复合物沉积均有不同程度的下降,以中西医结合治疗组降低最为明显。结论:中药清热解毒补肾方及西药强的松、环磷酰胺对狼疮样小鼠模型均有良好的治疗作用,而中西医结合治疗效果最好。更多还原

【Abstract】 Part One Induction of lupus nephritis models of intraperitoneal injection lipopolysaccharideObjective:To investigate the method to establish murine lupus nephritis models by intraperitoneal injection lipopolysaccharide (LPS). Methods: 80 mice were divided into four groups and were given NS or three different LPS doses (5mg*kg-1, 2.5mg*kg-1, 1.25mg*kg-1) respectively. Results: Compared with control group, the pathological change of kidney were appeared in 5mg*kg-1 and 2.5mg*kg-1 groups. The content of protein in 24 hours urine, the serum antinuclear antibody, and the deposition status of immune complex in nephritis of lupus were remarkably increased in 5mg*kg-1 group and 2.5mg*kg-1 groups than those in control group and 1.25mg*kg-1 group. The mortality of mice with LPS i.p in 5mg*kg-1 group was remarkably increased than that in other groups. Conclusion: The dose of LPS with 2.5mg*kg-1 i.p. injected can induce lower mortality than with 5mg*kg-1 in establishing SLE models and it can be used as an appropriate model for further research.Part Two Effects of combined treatment of traditional Chinese medicine and western medicine on Murine Lupus Nephritis ModelsObjective: To study the effects of combined treatment of traditional Chinese medicine and western medicine on Murine Lupus Nephritis Models. Methods:120 mice were made to murine lupus nephritis models with LPS by intraperitoneal injection. These mice were divided into six groups and were given distilled water, Qingrejiedubushen Decoction, prednisone, cyclophosphamide, Bushenqingrejiedu Decoction plus prednisone, and Qingrejiedubushen Decoction plus cyclophosphamide by intragastric administration (1 time per day) for 15 days respectively. Results: Compared with control group, the mortality, the content of protein in 24 hours urine, the serum antinuclear antibody, and the deposition status of immune complex in nephritis of lupus were remarkably decreased in all treatment groups, especially in combined treatment of traditional Chinese medicine and western medicine groups. Conclusion : Prednisone, cyclophosphamide, and Qingrejiedubushen Decoction all have therapeutic effects on Murine Lupus Nephritis Models, and the therapeutic effects of combination of traditional Chinese medicine and western medicine are better than others.更多还原
