Neutralizing potency of the patent recombinant anti-rabies virus McAbs, SO57 and SOJB,have been investigated broadly to different rabies virus strains in various animal models.100% Chinese Hamsters could be protected by 100IU/kg SO57 against China prevalent street rabies virus named SBD.We firstly established the mouse model to simulate human postexposure prophylaxis by rabies virus and found SO57 had the same function with HRIG against CVS or three China typical street rabies viruses.However,HRIG could not 100% protect the mice challenged with SBD street virus,rabies virus vaccine alone could not save life from rabies virus infection.The cocktail containing SOJB and SO57(1:1) did not do better than SO57 alone.
用不同的动物模型研究了具有专利的重组人抗狂犬病病毒单克隆抗体SO57、SOJB对不同狂犬病病毒株的中和作用,100IU/kg的SO57能100%保护被中国街毒株SBD攻击的中国仓鼠;首次用小鼠模型模拟人体被狂犬病病毒攻击后的治疗情况,在小鼠被CVS及中国街毒代表株攻击后,SO57与HRIG具有相近的对小鼠的暴露后保护作用;同时结果显示HRIG对SBD株攻击的保护率不能到达100%,仅使用疫苗是不能对感染病毒的小鼠百分之百的保护;SOJB与SO57 1:1联合使用未显示比SO57单独使用更好的保护效果。

The results showed that there existed variation among eucalypt families in wood physical-mechanical properties and wood chemistry. There were significant differences among E.pellita families、E.grandis families and E.urophylla譋.grandis clones in wood colors as well as between Strains and within trees.The variation of the surface wetability of wood between E.grandis families and E.urophylla譋.grandis clones were significant.Even in the same families level or clones level,there still existed the same regulation. The degree of collapse of eucalypt had a large relation in the amount of tylosis in vessel and vestured pits on the cell wall of vessel. The more rich tylosis and vestured pits in vessels,the more probability to occur collapse for eucalypt.The biggest moment collapse was probably the critical point of the drying degrade.During the fomulation of drying technology,it is necessary to adopt moderate condition to make the vessels which had formed the biggest moment collapse at the biggest moment collapse resume,especially to prevent the permanent set.At the normal temperature level,the main factors which influenced residual collapse were the contents of ray parenchyma and axial parenchyma .Nearly all the cells joined the course of forming the moment collapse and biggest moment collapse.Interval drying was fit for eucalypt plantation which was easier to make collapse.
研究表明:桉树不同家系间木材物理力学性质和化学组成存在差异;粗皮桉家系间、巨桉家系间、尾巨桉无性系间材色存在显著差异,株间、株内木材材色存在变异;桉树木材表面润湿性在巨桉家系间、尾巨桉无性系间存在着显著差异,在同一家系或同一无性系中,株间和株内也存在着相同的变化规律;桉材皱缩程度与其导管中侵填体的多少和导管壁上纹孔具有的附物多少密切相关,侵填体含物越丰富,纹孔附物越多,桉材越容易皱缩;最大瞬间皱缩是能产生更大干燥降等的临界点,在制定干燥工艺时,必须在最大瞬间皱缩发生时,采用温和条件,使已产生最大瞬间皱缩的细胞尽可能多的恢复,尤其不能使其产生永久变定;在常温条件下,影响残余皱缩的主要因子是射线薄壁细胞和轴向薄壁细胞含量;而对于瞬间皱缩和最大瞬间皱缩,几乎所有细胞都参与它们的形成过程;对于易皱缩的桉树木材,间歇干燥是最有前途的干燥方法。

The oxygen uptake activity using Triton X- 100 as substrate in a resting cell experiment demonstrated that one of the isolates, P nitroreducens TX1, showed the highest activity to transform Triton X-lOO, 528 nmole/min/g cell wet weight among the isolates. The generation time of strain TX1 was only 1.2 h by using 0.5% of Triton X-100 as sole carbon source in MSB medium. Furthermore, this strain could even grow on the Triton X-l00 at a concentration of IO%-2O%.
