ABSTRACT
Objective:The immunodeficiency animals play more and more important role in oncology research.But researchers usually do not how to choose kinds of immunodeficiency rats and mice during experiments.In this paper, applications and characteristics of immunodeficiency animals were compared as well as some of the common problems were discussed in oncology study.Methods:Classification of the immunodeficiency animals, the characteristics and application of congenital immunodeficiency rats and mice, and common problem analysis in the study of oncology were explored.Results: The feature of various immunodeficiency rats and mice should be considered in the oncology experiments.Conclusion:The paper provide valuable reference for scientific researcher.
ABSTRACT
Objective To observe the effect of Natural mountain spring on oxidative damage of aging mice . Methods Thirty male aging mice were randomly divided into experimental group ( drink Natural mountain spring ) and control group ( drink tap water ) according to the level of MDA .The serum in the two groups was taken for T-SOD activity and MDA content analysis after two months .Results The MDA content in experimental group decreased markedly than that in control group .Conclusion Natural mountain spring could alleviate oxidative damage by free radicals to extent .
ABSTRACT
Laboratory animal science teaching has become an indispensable part of medical education.This paper summarized teaching characteristics of laboratory animal science at different levels, including the curriculum setting background, curriculum arrangement as well as assessment methods, in order to provide some references for the teaching staff of laboratory animal science.
ABSTRACT
The genetically modified mice , as a helpful model , have been widely used in life scientific research . However, several new issues appeared subsequently with the wide application of the genetically modified mice .Here, we mainly discussed and analyzed the problems in the management and usage of genetically modified mice , which underlies the foundation for establishing management practice of the genetically modified mice .
ABSTRACT
Objective Application of Case-based teaching method (CTM) in the class of Experimental Animal Quality Control aims to break the traditional teacher-centered and textbookcentered teaching model,to invoke students' interest and creativity by integrating practice and theory,and to cultivate their capacity in identifying,analyzing and solving problems.Methods According to different requirements of teaching contents,students were organized to discuss practical cases about quality control of experimental animals through problem-centered learning style.Results Students' capacity was enhanced in terms of problem solving with acquired knowledge,and the ability to pursue new knowledge,the intriguing and vivid cases stimulated students' interest,activated classroom atmosphere,and helped improve teaching efficiency.Conclusion Experimental animal quality control is a complicated system; Case-based teaching method leads to higher efficacy of the course of Experimental Animal Quality Control.
