A simple fastening device for local infrared irradiation in rats / 中国比较医学杂志

ABSTRACT

Objective To construct a rat fixation device for local infra-red irradiation in rats, observe the binding effect of this fixation device, and assess its practical application.Methods Twelve SD rats were held by this home-made simple device.The holding time was recorded at room temperature (24℃ to 26℃), 38℃ to 39℃ and 42℃ to 43℃ by infrared irradiation, respectively, and the maximum observation point was 60 min.Results Most rats (10/12) were held for more than 30 minutes at room temperature, 38℃ to 39℃ and 42℃ to 43℃ infrared irradiation.While 8 rats reached 60 min.There was no statistically significant difference among the holding times at various temperatures (P > 0.05).Conclusion This self-made device is simple, easy to operate and can be used to hold rats for a long time, and is a convenient and reliable holding device in animal experiments.
