A Preliminary Study on Effect of Electro-Acupuncture by the Cortical Infrared Thermography

To explore the possibility of using conical infrared infrared thermography(CIT) and temperature in studying the principle of acupuncture and moxibustion, Methods: The changes of the cerebral cortical temperature during electro-acupuncture (EA)by CIT in twenty cats were observed. By openingskull before experiments the cortex of animals was revealed. The distribution of the conical temperature of the awakend animals was studied by AGA Infrared Thermovision, the thermograms were analysed by computer. Results: (1 ) The thermograms of the profile of the cortex could be displayed clearly, the temperature was higher and lower in ante-and post-cortex respectively than that in other regions. (2) The conical temperature declined slightly during 30 minutes in cats without EA. (3) AfterEA, the temperature of cortex generally incrased 0. 3 to 1. 7 degrees centigrade, at 5min after EA,the temperature increment was the highest, at 10 min after EA, the temperature increment was higherthan before EA but lower than 5 min after EA , the conical temperature recovered 10 min after stopping stimulating. (4)The temperature increment was more obvious in the regions of Ant. Ectosylvian, Ant. Suprasylvian and Ant. Sylvian than that in other regions. No matter where the site of EA was,every group bed its region of higher temperature increment. The regions of the temperature incrementin the cortex were mainly in the somatesthesia regions. There were similar characteristics between thetemperature re8POnse in the cortex showing by CIT after EA and the activity of conical nerve cells after stimulation. Conclusion: The display of the temperature response could be taken as the indicationof the nervous activity. CIT could be used to conduct the studies of the acupuncture and brain.
