Summary
A new rat restrainer effectively immobilizes young rats for experiments. This device allows for safe, repeated in vivo exposure to ultraviolet radiation (UVR) without anesthesia.
Area of Science:
- Animal models
- Optical radiation research
- Physiological experimentation
Background:
- Immobilization of rats is crucial for various psychological and physiological studies.
- Existing methods may lack adaptability for different rat ages or convenience for in vivo experiments.
Purpose of the Study:
- To develop a universal rat restraining device for experiments.
- To enable convenient in vivo optical radiation exposure in non-anesthetized rats across a wide age range.
Main Methods:
- Eighty-three 6-week-old and three 18-week-old Sprague-Dawley rats were habituated to the device over 5 days.
- Unanesthetized rats were exposed to a single dose of 8 kJ/m² UVR-300 nm for 15 minutes.
- Some rats underwent repeated UVR exposure for 10 consecutive days.
Main Results:
- All rats successfully acclimatized to the immobilization device.
- The restrainer effectively prevented head and body movement during exposures.
- Both single and repeated in vivo UVR exposures were uncomplicated.
Conclusions:
- The developed restrainer effectively immobilizes rats aged 6-18 weeks.
- This device is suitable for future research involving chronic, repeated in vivo eye exposure to UVR.
