Using an Action Research Framework to Explore Assessment: A South African Case Study

This article is a reflection of my first experience with action research in trying to devise a system of assessment that would benefit both first and second language speakers of English in an assessment system that is plagued by its separatist past. In this paper, I discuss an action research study on oral assessment implemented at two tertiary institutions in South Africa. The actual details of each phase of the assessments are not reported on, but the methods used to facilitate the processes are. The findings and adaptations after each phase of the assessments are discussed to show the effectiveness of using an action research methodology.

对西藏大学新闻实践教学的几点思考

西藏大学地处少数民族地区,新闻教育有其独特的地域特色。文章认为在保持、发扬这一特色的同时,针对我区新闻事业发展趋势与学生实际,有必要增设涉及广播电视媒体的课程,加强实践锻炼;增设口语课程,针对专业特点进行口语训练;加强思辨能力的培养,使之贯穿实践教学的始终。     

多态四膜虫在嗜热四膜虫诱导下胞口类型分化中的细胞反应

本文研究了多态四膜虫Tetrahymena vorax在其亲缘种即嗜热四膜虫Tetrahymena thermophilia诱导下的胞口类型转化过程。大胞口型T.vorax细胞的形成与小胞口型T.vorox及诱导细胞T.thermophilia在混合悬浮中的起始密度有关。而且,不同胞龄的T.vorax细胞其转化成大胞口细胞的能力及所需时间有所不同。连续的机械振荡可以不同程度的阻碍这种转化。

Presence of hsp65 in bacterial extracts (OM-89): A possible mediator of orally-induced tolerance?

Heat shock proteins (HSP) have been implicated in rodent models of autoimmunity, particularly arthritis, and there is suggestive though inconclusive evidence that they may also play a role in human autoimmune disease. The simplest hypothesis is based on molecular mimicry due to the amino-acid sequence homology between mammalian and microbial HSP. Recently OM-89, an extract of several strains ofEscherichia coli, has shown some efficacy in the treatment of rheumatoid arthritis (RA) when taken orally. Using species-specific antibodies, we show here that OM-89 contains the 65 kDa HSP (hsp65), while hsp65 was not detected in another bacterial extract containing other microorganisms, includingStaphylococcus aureus (OM-85). We suggest that if the human homologue of hsp65 is a relevant target antigen in the human disease, the efficacy of the preparation could be due to induction of oral tolerance or to switching the Th1 response towards Th2. Alternatively, even if the human hsp65 is not a target molecule in RA joints, OM-89 may evoke bystander suppression of joint inflammation via induction of TGF-secreting effector cells. These hypotheses should be tested in further studies.

老板口服液的急性及长期毒性研究

老板口服液急性毒性实验，小鼠灌胃剂量达４０ｇ／ｋｇ时，未出现毒性症状和死亡现象．腹腔注射给药ＬＤ５０为１１．５６ｇ／ｋｇ．大鼠长期毒性实验分别灌胃给药１０ｇ／ｋｇ、５ｇ／ｋｇ和２．５ｇ／ｋｇ，连续６周．各组无动物死亡．动物外观、体重增长、血象、肝肾功能及各脏器指数与对照组无明显差异．脏器组织检查高剂量组１３只大鼠中有２只大鼠少量肝细胞脂肪样变．但留存动物于停药３周后，病检均正常．提示老板口服液临床口服用药安全范围较大．
