皮层红外热像显示法用于电针效应初步研究

目的：为探讨皮层红外热像显示法（ＣＩＴ）和温度指标用于针灸原理研究的可能性。方法：应用ＣＩＴ方法观察电针后猫大脑皮层的温度反应。结果：（１）侧面观猫大脑皮层热像图清晰，前半部皮层温度较高；（２）不针刺对照的３０ｍｉｎ内皮层天升温趋势；（３）电针后皮层温度以升高为主（０．３～１．７℃不等），电针５ｍｉｎ时升温最高，停针后温度回降；（４）电针后除前外雪氏回、前上雪氏回和前雪氏回升温显著外，各穴位组似还有特异升温区。结论：电针后大脑皮层的升温以体感区为主，ＣＩＴ方法可以用图像形式直观显示电针后皮层温度反应大小和部位。

英文摘要:

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.
