Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword. 
Tavera-Mendoza, L. E., Brown, M. 2017. A less invasive method for orthotopic injection of breast cancer cells into the mouse mammary gland. Laboratory Animals 51(1), 85-88.

Breast cancer is the most common type of cancer diagnosed in women, and the second most common cause of cancer-related deaths in women in North America. The use of laboratory mice in research is an...

Larsen, R. A., Peveler, J. L., Klutzke, J. B. et al. 2017. Effects of daily restraint with and without injections on skeletal properties in C57BL/6NHsd mice. Lab Animal 46(7), 299-301.

Studies typically involve groups of animals that are injected with placebo compounds. As there are studies that demonstrate that restraint and injection can affect behavior and corticosteroid levels in rodents, the basis of such placebo...

Hubbard, J. S., Chen, P. H., Boyd, K. L. 2017. Effects of repeated intraperitoneal injection of pharmaceutical-grade and nonpharmaceutical-grade corn oil in female C57BL/6J mice. JAALAS 56(6), 779-785.

Due to potential adverse effects on animal wellbeing, the use of nonpharmaceutical-grade substances in animal research must be scientifically justified in cases where a pharmaceutical-grade version of the substance exists. This requirement applies to all...

Polissidis, A., Zelelak, S., Nikita, M. et al. 2017. Assessing the exploratory and anxiety-related behaviors of mice. Do different caging systems affect the outcome of behavioral tests? Physiology & Behavior 177, 68-73.

Ample studies have shown that housing can affect the health, welfare and behavior of mice and therefore, the outcomes of certain experiments. The aim of this study was to investigate if three widely used housing...

Gardiner, P. 2016. Going outside ASPA guidelines. Animal Technology and Welfare 15(1), 47-52.

This article will discuss an improved and refined technique used for working and caring for a group of diabetic mice. As a team of animal technologists, academics and named veterinary surgeon, we developed a new...

Sneddon, L. U., Elwood, R. W., Adamo, S. A. et al. 2014. Defining and assessing animal pain. Animal Behaviour 97, 201-212.

The detection and assessment of pain in animals is crucial to improving their welfare in a variety of contexts in which humans are ethically or legally bound to do so. Thus clear standards to judge...

Õkva, K., Nevalainen, T., Mauranen, K. et al. 2010. The effect of three different items of cage furniture on the behaviour of male C57BL/6J mice in the plus-maze test. Animal Welfare 19(4), 401-409.

The aim of this study was to assess the effects of specific regimens of enrichment on the behaviour of C57BL/6J mice in the elevated plus-maze test (EPM). A total of 192 male C57BL/6J mice were...

Li, W. J., Yu, H., Yang, J. M. et al. 2010. Anxiolytic effect of music exposure on BDNFMet/Met transgenic mice. Brain Research 1347, 71-79.

Brain-derived neurotrophic factor (BDNF) has been reported to play important roles in the modulation of anxiety, mood stabilizers, and pathophysiology of affective disorders. Recently, a single nucleotide polymorphism (SNP) in the BDNF gene (Val66Met) has...

Meijer, M. K., Spruijt, B. M., van Zutphen, L. F. M. et al. 2006. Effect of restraint and injection methods on heart rate and body temperature in mice. Laboratory Animals 40(4), 82-391.

It was found that heart rate (HR), and to a lesser extent also body temperature (BT), parallels plasma corticosterone (pCORT) values after subjecting the animals to different methods of restraint. Secondly, the acute stress response...
