Comparison of nociceptive effects of buprenorphine, firocoxib, and meloxicam in a plantar incision model in Sprague–Dawley rats

Due to their reduced frequency of dosing and ease of availability, NSAIDs are generally preferred over opioids for rodent analgesia. We evaluated the efficacy of the highly COX2-selective NSAID firocoxib as compared with meloxicam and buprenorphine for reducing allodynia and...

Distress analysis of mice with cervical arteriovenous fistulas

The welfare of laboratory animals is a consistent concern for researchers. Its evaluation not only fosters ethical responsibility and addresses legal requirements, but also provides a solid basis for a high quality of research. Recently, a new cervical arteriovenous model...

Refining cages for social housing of non-human primates on ADME studies

The assessment and understanding of Absorption, Distribution, Metabolism and Elimination (ADME) for new pharmaceuticals is required in regulatory submissions. Typically, ADME studies are conducted using metabolism cages designed for the single housing of animals to enable the quantitative collection of...

Diagnostic ability of methods depicting distress of tumor-bearing mice

Subcutaneous tumor models in mice are the most commonly used experimental animal models in cancer research. To improve animal welfare and the quality of scientific studies, the distress of experimental animals needs to be minimized. For this purpose, one must...

A novel model of ischemia in rats with middle cerebral artery occlusion using a microcatheter and zirconia ball under fluoroscopy

Here, we present a highly selective rat MCAO model by percutaneous caudal arterial puncture using a microcatheter and zirconia ball under fluoroscopic guidance. The model is predictable and reproducible, which is well confined within the territory supplied by the MCA,...

Environmental enrichment and mouse models: Current perspectives

The provision of environmental enrichment to numerous species of laboratory animals is generally considered routine husbandry. However, mouse enrichment has proven to be very complex due to the often contradictory outcomes (animal health and welfare, variability in scientific data, etc.)...

Comparison of the effects of osmotic pump implantation with subcutaneous injection for administration of drugs after total body irradiation in mice

The increasing potential for radiation exposure from nuclear accidents or terrorist activities has intensified the need to develop pharmacologic countermeasures against injury from total body irradiation (TBI). Many initial experiments to develop and test these countermeasures utilize murine irradiation models....

Effects of analgesics on tumor growth in mouse models of prostate cancer bone metastasis

Murine models of tumor development often require invasive procedures for tumor implantation, potentially causing pain or distress. However, analgesics are often withheld during implantation because of concerns that they may adversely affect tumor development. Previous studies examining the effects of...
