[Effects of Restraint Manipulation on Learning-memory Ability, Visional Acuity and Body Mass of Rats]

Restraint manipulation is necessary for observing the effect of acupuncture or moxibustion stimulation on various variables in the experimental study. Thus, the present study was designed to examine the impact of restraint manipulation on rats' learning-memory ability, visional acuity, and body mass, so as to have a reasonable assessment on the influence of restraint stress.Normal Sprague Dawley rats were randomly assigned to a restraint group (After 30 days' restraint, no significant differences were found between the two groups in the training times for acquiring a correct rate of 80% in the learning-memory tests, and visional acuity and body mass (P ﹥0.05).Thirty days' restraint has no obvious impact on the increase of body weight, learning-memory and visional acuity in normal rats, suggesting an applicable of restraint device in acupuncture study.
