背景：近年来，人体离体细胞和组织的超弱光子发射（UPE）研究日益增多。然而，关于普及初等教育的全身数据，特别是手部数据有限。目的：描述受试者管理方案，（1）避免干扰光诱导的长期延迟发光，（2）包括记录光子发射的时隙。材料和方法：该方案用于在一天的不同时间和不同季节对4名受试者进行多部位记录，并用于一名受试者完成对不同身体部位发射的光谱分析。特别选择的低噪声端窗光电倍增管用于检测紫外/可见光（200-650 nm）光子发射。对于多点记录，在暗室中以非常低的计数率在三个方向上操作。采用一系列截止滤光片对不饱和聚酯进行光谱分析。选择了29个身体部位，以便可以研究UPE中的分布，如左右对称、背腹对称以及中心身体部分与四肢之间的比例。结果：上午全身光子数波动一般低于下午。胸腹部放射最低，最恒定。一天中，上肢和头部区域的排放量最多，而且越来越多。在光电倍增管的灵敏度范围内，对来自右腿的上级额部、前额和手掌的低、中、高发射的光谱分析表明，主要的自发发射在470-570 nm。在秋冬季节，手掌中心区的自发辐射光谱中，420-470 nm波段的贡献较大。手的延迟发光光谱显示出与自发发射相同范围的主要发射。结论：多站点UPE记录和光谱分析的例子揭示了个体模式和自发UPE的动态，以及全身的光谱差异。光谱数据表明，测量可能会提供定量数据的个人模式的过氧化和抗氧化过程在体内。我们期望这些测量提供的生理信息可以用于临床检查。
Background: In the past years, research on ultraweak photon emission (UPE) from human body has increased for isolated cells and tissues. However, there are only limited data on UPE from the whole body, in particular from the hands. Objective: To describe a protocol for the management of subjects that ( 1) avoids interference with light-induced long-term delayed luminescence, and ( 2) includes the time slots for recording photon emission. Material and Methods: The protocol was utilised for multi-site recording of 4 subjects at different times of the day and different seasons, and for one subject to complete spectral analysis of emission from different body locations. An especially selected low-noise end-window photomultiplier was utilised for the detection of ultraviolet/visible light (200-650 nm) photon emission. For multi-site recording it was manipulated in three directions in a darkroom with a very low count rate. A series of cut-off filters was used for spectral analysis of UPE. 29 body sites were selected such that the distribution in UPE could be studied as right-left symmetry, dorsal-ventral symmetry, and the ratio between the central body part and extremities. Results: Generally, the fluctuation in photon counts over the body was lower in the morning than in the afternoon. The thorax-abdomen region emitted lowest and most constantly. The upper extremities and the head region emitted most and increasingly over the day. Spectral analysis of low, intermediate and high emission from the superior frontal part of the right leg, the forehead and the palms in the sensitivity range of the photomultiplier showed the major spontaneous emission at 470-570 nm. The central palm area of hand emission showed a larger contribution of the 420-470 nm range in the spectrum of spontaneous emission from the hand in autumn/winter. The spectrum of delayed luminescence from the hand showed major emission in the same range as spontaneous emission. Conclusion: Examples of multi-site UPE recordings and spectral analysis revealed individual patterns and dynamics of spontaneous UPE over the body, and spectral differences over the body. The spectral data suggest that measurements might well provide quantitative data on the individual pattern of peroxidative and anti-oxidative processes in vivo. We expect that the measurements provide physiological information that can be useful in clinical examination.
