Opportunities for refinement of non-human primate vaccine studies

Non-human primates (NHPs) are used extensively in the development of vaccines and therapeutics for human disease. High standards in the design, conduct, and reporting of NHP vaccine studies are crucial for maximizing their scientific value and translation, and for making...

Refinements in diabetic research – a technician led initiative

A genetically altered diabetic mouse model (Ins2akita) was introduced to the facility two years ago. From information available, it was expected that heterozygous animals would develop hyperglycaemia, hyperinsulinemia, polydipsia and polyuria by 3 to 4 weeks old with males exhibiting...

Refining the adjuvant-induced rat model of monoarthritis by optimizing the induction volume and injection site

Arthritis is a highly prevalent and disabling condition characterized by pathological joint-damage, clinical symptoms of pain and loss of normal joint function. Monoarthritis can be modelled in rodents via intraarticular injection of Complete Freund’s Adjuvant (CFA), inducing both joint inflammation...

A rational approach of early humane endpoint determination in a murine model for cholestasis

Reduction of animal suffering during in vivo experiments is usually ensured by continuously monitoring the health status using a score sheet and by applying humane endpoints. However, most studies do not evaluate the plausibility of score sheets and do not...

Defining and managing pain in stroke and traumatic brain injury research

Neurologic conditions such as stroke and traumatic brain injury are challenging conditions to study in humans. Animal models are necessary to uncover disease processes and develop novel therapies. When attempting to model these or other neurologic diseases, the accompanying anesthesia...

Use of flavored tablets of gabapentin and carprofen to attenuate postoperative hypersensitivity in an incisional pain model in rats (Rattus norvegicus)

Providing postoperative analgesia to rats by oral administration, compared with injections, reduces stress from frequent handling and is technically easier for investigators. The purpose of this study was to investigate whether bacon-flavored tablets containing gabapentin, carprofen or a combination of...

Wheel running behaviour in group-housed female mice indicates disturbed wellbeing due to DSS colitis

Voluntary wheel running (VWR) behaviour is a sensitive indicator of disturbed wellbeing and used for the assessment of individual experimental severity levels in laboratory mice. However, monitoring individual VWR performance usually requires single housing, which itself might have a negative...

The effect of housing environment on bone healing in a critical radius defect in New Zealand white rabbits

In animal studies on bone healing, the effect of housing space and physical activity are seldom taken into account. Bone formation was evaluated in New Zealand White rabbits (mean ± SEM BW: 3.9 ± 0.11 kg) with a critical bone...

Severity assessment in pigs after partial liver resection: Evaluation of a score sheet

Severity assessment in biomedical research is required by the European authorities. Therefore, a variety of score sheets are available. The first score sheets were designed and introduced by Morton and Griffith (M&G) in 1985, to assess pain and distress in...

Severity assessment using three common behavioral or locomotor tests after laparotomy in rats: A pilot study

The aim of this pilot study was to evaluate whether behavioral or locomotor tests (Open Field (OF), rotarod (RR), and CatWalk (CW)) can help assess the severity of laparotomy in rats. The new EU Directive (2010/63/EU) mandates severity assessment in...
