[Objective]To observe the effect of Homoharringtonine on Adjuvant Arthritis Rats.[Methods]Observe the effect of Homoharringtonine on Adjuvant Arthritis Rats’ SP,IL-1? and TNF-?;we take the Adjuvant Arthritis Rats as model and Tripterygium wilfordii polycoside was the positive group.[Results]The Homoharringtonine and Tripterygium wilfordii polycoside group’s level of TNF-?,IL-1? in the serum and synovial membrane decreased instructively,and their dose of SP in the plasma and synovial membrane was suppressed obviously too.[Conclusion]Homoharringtonine has the effect of anti-inflammation,it may treat the Adjuvant Arthritis Rats through reducing the dose of TNF-?,IL-1? in the serum and synovial membrane,inhibiting the secretion and releasing SP in the plasma and synovial membrane.

To investigate the pathogenic characteristic of ToxoDB # 17 Toxoplasma gondii in Kunming mice,the mice were fed with <1,1,101,102,103,104,105,106 oocysts,and the clinical symptoms of mice were observed.MAT,HE and IHC were used to research the infection rate of T.gondii,survival rate of mice and the number of cysts in brain.The results showed that the mice fed with ≥104 oocysts appeared transient depression,mice were arched,messy hair after infection.The mice fed with ≥102 oocysts were all infected,T.gondii cysts formation rate was 2.38% (1/42),the survival rate of infected mice was 85.71% (36/42),the survival time was greater than 360 days.In conclusion,the pathogenicity of ToxoDB# 17 T.gondii is weak,and cysts formation rate is also low.
