摘要 目的探讨雷公藤内脂醇(TRD)和地塞米松(DXM)联合使用对实验性自身免疫性脑脊髓炎(EAE)大鼠临床指标和单核细胞趋化蛋白(MCP)-1 mRNA的影响。方法用完全抗原和百日咳原液免疫大鼠后7 d随机分成6组即EAE组、TRD1组、TRD2组、TRD3组、DXM组和联合用药组,经其腹腔分别注射0.5 mL NS/d、10μg TRD/d、20μg TRD/d、40μg TRD/d1、mg DXM/d和20μg TRD+0.5 mg DXM/d。取脑和脊髓制成石蜡切片,进行HE和MCP-1 mRNA原位杂交(ISH)染色,比较各项临床指标。结果TRD3组、DXM组和联合组的发病率分别为15%、0、0,临床评分分别为(0.5±1.29)、0、0,MCP-1 mRNA阳性细胞数分别为(15±6)、(2±1)(、6±2),与EAE组、TRD1组、TRD2组[发病率分别为82%、60%、73%,临床评分分别为(3.5±1.72)、(2.25±2.00)、(2.5±1.88),MCP-1 mRNA阳性细胞数分别为(69±26)、(57±33)、(62±28)]比较均显著降低(P<0.01)。结论减少TRD和DXM药量并联合使用对EAE疗效显著,可为临床治疗多发性硬化(MS)提供理论基础。 Objective To investigate the immunosuppressive effects of combined intra-peritonial injection of triptolide (TRD) and dexmethesone (DXM) on clinical index and monoeyte chemokine protein (MCP-1)mRNA expression in Wistar rats with experimental autoimmune encephalomyelitis(EAE). Methods Complete antigen and pertussis toxin-immunized Wistar rats are divided randomly into six groups: EAE group, TRD1group. TRD2group, TRD3group, DXM group,united group, and injected intraperitoneal respctively 0. 5 mL NS/d, 10 μg TRD/d, 20μg TRD/d, 40 μg TRD/d. 1 mg DXM/d, 20μg TRD+0.5 mg DXM/d. The brains and spinal cords were removed for HE staining and in situ hybridizations(ISH) staining. Results Compared with EAE group. TRD1 group, TRD2 group ( Morbidity: 82 %, 60 %, 73% Clinical score ;( 3.5±1.72 ), ( 2. 25 ±2.00), ( 2. 5±1.88) ; MCP-1 mRNA positive cell; ( 69±26 ), ( 57±33 ), ( 62±28 ) . The morbidity ( 15 %, 0,0 ), Clinical score (0. 5±1.3,0,0)and MCP-lmRNA positive cell [(15±6), (2±1), (6±2)]of group TRD3, group DXM and united group decrease strikingly. Conclusions TRD co-treatment with DXM have immunosuppressive effects to EAE.and can supply theorical basis for the remedy of multiple sclerosis.
