[目的]研究微电流对紫外线诱导的炎症反应的影响。[对象和方法]我们招募了22名受试者，在每个受试者的腰部用紫外线照射诱导两个炎症反应区。将微电流施加到一个区域，频率为5pps，强度为50mA，而不对另一个区域施加交替的微电流。每隔1秒对照射区域进行分析，并进行数字图像分析和定量感觉测试。[结果]色红和亮度随时间和区域间的变化有统计学意义。两区伤口收缩程度比较，差异有统计学意义。痛阈值变化的分析显示没有统计学意义的差异。[结论]本研究发现微电流增加创面收缩，减少红斑、色素沉着等炎症反应活动。因此，我们认为微电流有助于加速紫外线诱导的炎症反应，促进恢复，促进抗炎反应。
[Purpose] This study examined the effects of microcurrents on inflammatory reactions induced by ultraviolet irradiation. [Subjects and Methods] We recruited 22 subjects and two inflammatory reaction regions were induced on the lumbar region of each subject with ultraviolet irradiation. Microcurrents were applied to one region at a frequency of 5 pps, an intensity of 50 mu A, and alternation of no microcurrents were applied to the other region polarity. The irradiated regions were analyzed by at 1 sec intervals; the digital image analysis and the quantitative sensory test. [Results] Changes in chromatic red and luminance there were statistically significant showed over time and between regions. The comparison of wound contraction in the two regions there was a statistically significant difference. Analysis of changes in pain threshold showed no statistically significant difference. [Conclusion] This study found that microcurrents increased wound contraction and reduced the inflammatory reaction activities such as erythema and pigmentation. Thus, we consider that microcurrents help to accelerate the inflammatory reaction induced by ultraviolet irradiation, enhance recovery and foster an anti-inflammatory reaction.
