A Technique to Generate and Deliver Drug Aerosols Directly to Mouse Lungs
0 Views •
2025
This video demonstrates the generation of drug aerosols and the targeted nose-only delivery of these aerosols to mice using an inhalation unit equipped with an aerosol generator. The mouse is restrained in a nose-only restrainer and connected to the inhalation unit, which delivers the drug directly into the mouse's nasal cavity. Subsequently, the drug passes through the trachea and enters the lungs.

A Technique for Human Skin Grafting in a Mouse Model

This video demonstrates a method for grafting human skin onto an immunodeficient mouse with a suppressed neutrophil response. The method involves applying human split-thickness skin to the mouse's graft bed, sealing it, and covering it for recovery. Eventually, the human skin adheres to the mouse's skin, establishing vascularization and circulation, resulting in a successful skin xenograft.

Non-restraining EEG radiotelemetry is a valuable methodological approach to record in vivo long-term electroencephalograms from freely moving rodents. This detailed protocol describes stereotaxic epidural and deep intracerebral electrode placement in different brain regions in order to obtain reliable recordings of CNS rhythmicity and CNS related behavioral stages.

FAQs
Correct sizing helps the device support the mouse while exposing the intended area without creating unnecessary pressure or allowing excessive movement. The restrainer must be appropriately sized for the animal and suited to the planned handling task. This balance improves positioning and procedural consistency while reducing the likelihood of discomfort, stress, or injury during the intervention.
A ventilated tube or cone combines two practical functions: it supports the mouse’s body and permits access to a selected area. Ventilation is part of choosing a suitable device, not an optional detail, because restraint must be brief and monitored while minimizing discomfort, stress, and injury risk. The appropriate design therefore depends on both animal support and procedural access.
Brief restraint and careful monitoring are central safeguards. The mouse should not remain restrained longer than the procedure requires, and its condition should be observed throughout handling. If the fit, positioning, or duration is inappropriate, the technique can increase discomfort, stress, or injury risk. These safeguards are important during injection, blood collection, observation, and other interventions.
Limiting sudden movement can make handling more consistent because the selected area remains more controlled during the intervention. That consistency matters when researchers need reliable observations or data collection across procedures. Restraint does not replace careful technique: an incorrectly fitted device or unnecessarily prolonged use may undermine welfare goals and introduce discomfort, stress, or injury risk.
The operator first selects a purpose-designed device that is appropriately sized, such as a ventilated tube or cone. The mouse is positioned so the body is supported and the required area is accessible. The intervention is then performed with restraint kept brief, while fit, positioning, and the animal’s condition are monitored to reduce avoidable risks.
The technique can support several controlled tasks, including handling, observation, injection, and blood collection, as well as other interventions requiring stable access. Its value depends on matching the device and positioning to the task rather than treating restraint as a single fixed procedure. This task-specific approach can improve access and consistency while keeping welfare considerations central.
In medicine and biomedical research, the method links practical control with three broader goals: reliable data collection, personnel safety, and adherence to animal-welfare principles. Controlled positioning can help reduce sudden movement during a procedure, while brief use and monitoring help limit discomfort, stress, and injury risk. These combined aims explain its relevance beyond any one intervention.
