Methods The SpaA was purified by electroelution from NaOH-extracted antigen of Erysipelothrix rhusiopathiae strain C43311. The rSpaA-N was expressed in E. coli BL21 as a soluble protein by IPTG inducing,and purified with GST affinity chromatography. Mice of each group were subcutaneously immunized three times with 50μg or 100 μg of native SpaA, rSpaA-N or NaOH-extracted antigen with in complete or incomplete Freund adjuvant at 2-week intervals.

将猪丹毒丝菌C43311株SpaA-N以可溶形式表达在大肠杆菌BL21中，用GST Bind Resin纯化试剂盒纯化rSpaA-N，采用电洗脱法从猪丹毒丝菌C43311株NaOH提取抗原中纯化天然SpaA，将rSpaA-N、天然SpaA和NaOH提取抗原制成亚单位疫苗，同时设GST及生理盐水对照组，间隔2周分3次皮下免疫小鼠，第3次免疫后2周用100LD50猪丹毒丝菌C43065株进行腹腔攻毒，采用间接ELISA方法检测免疫组小鼠血清的抗体动态变化。

Blood samples were obtained on 0,2,4,6 and 8 days after admission. Dynamic changes of immunological parameters including serum IgA,IgG,IgM,complements (C3,C4) levels were determined in each group at various intervals following trauma. Phagocytosis of monocytes was also measured by use of phagotest kits after blood cells were incubated with fluorescin isothiocyanate-labeled E.

分别在入院时及入院后2、4、6和8 d留取外周静脉血，检测血清免疫球蛋白(IgA、IgG、IgM)与补体(C3、C4)水平的动态变化，全血细胞与用异硫氰酸荧光素标记的大肠杆菌共孵育后检测单核细胞噬菌能力。

He creative process for him has two stages. The writing is preceded by a long period of "sitting grumpily, staring out the window." That explains why his nine books, all of which are still in print, have appeared at unpredictable intervals.

他创作分两阶段，第二阶段是打字，对他而言要花上一年，这对熟练或量产作家来说算是不可思议的久，但更浪费时间的是第一阶段，&sitting grumpily， staring out the window。&
