Provision of food and water in rodent whole body plethysmography safety pharmacology respiratory studies – Impact on animal welfare and data quality

Introduction: We evaluated the feasibility of providing food and water to rodents during whole body plethysmography (WBP) studies as a welfare improvement to standard conditions. Methods: Male Han Wistar rats or CD1 mice (n=8) were placed in WBP chambers and...

Using paper nest pucks to prevent barbering in C57BL/6 mice

Little research has been conducted to examine the influence of various methods of providing nest materials—such as dispersing them, providing them as single units, or clustering them—on the behavior and welfare of group-housed mice. In this study, 6 wk-old C57BL/6NCrl...

Effects of cling film draping material on body temperature of mice during surgery

General anesthesia induces many systemic effects, including thermoregulatory impairment and subsequent perioperative hypothermia. Due to the animals' small size, monitoring and maintaining body temperatures in laboratory rodents during anesthesia is important for successful surgical outcomes and prompt anesthetic recovery. Draping...

A validated smartphone-based electrocardiogram reveals severe bradyarrhythmias during immobilizing restraint in mice of both sexes and four strains

Mouse handling and restraint affect behavior, physiology, and animal welfare, yet little information is available on how various mouse restraint methods affect cardiovascular parameters. We validated the use of a smartphone-based ECG sys- tem in mice by performing simultaneous smartphone...

Comparison of two hair removal methods in Sprague–Dawley rats (Rattus norvegicus)

Rats commonly undergo surgery for research purposes. However, the effects of different methods of hair removal on wound healing and surgical site infections (SSI) in rats has not been evaluated. The current study evaluated 2 hair removal methods, clipping with...

Comparison of direct and indirect methods of measuring arterial blood pressure in healthy, anesthetized African green monkeys (Chlorocebus aethiops)

Quantitative blood pressure measurement is a critical parameter for assessing cardiovascular health, monitoring physiologic status under anesthesia, and making clinical decisions. The placement of an arterial catheter is the most accurate way to measure blood pressure, but is invasive and...

Effects of daytime blue-enriched LED light on physiologic parameters of three common mouse strains maintained on an IVC system

Light has been a crucial part of everyday life since the beginning of time. Most recently, light-emitting diode (LED) light enriched in the blue-appearing portion of the visible spectrum (465 to 485 nm), which is more efficient in energy use,...

Effects of oxygen supplementation on injectable and inhalant anesthesia in C57BL/6 mice

Oxygen supplementation is rarely considered when anesthetizing laboratory mice, despite reports that mice become profoundly hypoxic under anesthesia. Little is known about the effects of hypoxia on anesthetic performance. This article focuses on the effects of oxygen supplementation on physiologic...

Predictors of subcutaneous injection site reactions to sustained-release buprenorphine in rhesus macaques (Macaca mulatta)

Subcutaneous injection site reactions to sustained-release buprenorphine hydrochloride (Buprenorphine SR) in macaques have been reported in only a single case report. In the current study, we evaluated the incidence rate and predictors of buprenorphine SR reactions in the subcutaneous tissue...
