ABSTRACT
OBJECTIVE:
To observe the effect of infrared laser stimulation on Neiguan (PC 6) for bradycardia of rabbits induced by injection of pituitrin.METHODS:
10.6 microm CO(2) infrared laser, 650 nm semiconductor red laser and the compound laser of their aggregation were sent out by a compound laser sanatory instrument to stimulate Neiguan (PC 6) respectively for the purpose of analyzing the differences of the effects exerted by infrared laser and red laser as well as the changes of the effects after their aggregation.RESULTS:
After 30 min and 40 min of the injection of pituitrin, the heart rate showed no significant difference between 10.6 microm CO(2) infrared laser group and the normal control group (P>0.05). However, the heart rate showed significant difference between the 650 nm semiconductor red laser group and the normal control group (P0.05). However, the heart rate of non-acupoint stimulated by the compound laser group showed no significant difference to that of the untreated group (P>0.05), and it was significantly different to that of the normal control group (P<0.05).CONCLUSION:
Stimulation on Neiguan with 10.6 microm CO(2) infrared laser can evidently improve the bradycardia induced by injection of pituitrin, while the 650 nm semiconductor red laser has no such function, but they have coordinating effect. The thermal effect produced by CO(2) infrared laser stimulating acupoint is probably beneficial for semiconductor laser penetrating skin as well as the biochemical reactions it carries. The improvement of heart rate produced by the laser stimulation on Neiguan (PC 6) has relative specificity.
