Features In the
light of D’Amour and Smith (1941), the Tail Flick method is useful for
studying the effect of analgesic drugs such as narcotic drug or acute noxious
stimulus on both mouse and rat. The tail flick test is used in determining
pain sensitivity on animals by measuring latency of avoidance response when
pain is induced by radiant heat from a light source to the animal’s tail. The SINGA
Tail Flick Analgesia Instrument TF-01 measures reaction to radiant energy
from a light source. The highlight of the device is the shutter-controlled
halogen lamp which has the sensor built in for automatic tail flick
detection. The lamp is located below the animal to provide a less confining
environment and radiant heat provides a constant temperature to the animals’
tail, avoiding the lamp warm-up temperature variations. The animal is generally restrained and its tail is placed on a sensing tail groove on top of the instrument. When the animal reacts against pain, it flicks its tail out of the beam which automatically freezes the built-in latency timer and the stimulation stops. The reaction time from activation of the light beam to the tail flick is automatically presented on a digital display. Response time is measured in 0.01 second increments and displayed on a digital clock. Windows-compatible software may be directly exported to a computer for statistical analysis. |
