“…Influence of age on photon emission of hands has been reported in two studies. Sauermann et al [6] investigated two age groups (n = 20, age 18-25 vs. n = 20, age 60-72). Spontaneous photon emission from the hands was increased in elderly subjects.…”

“…Sauermann et al [6] reviewed applications of photon emission recording since the 1980's in studies on human skin that was treated with UV, ultrasound, topical applications of peroxides, and antioxidants. Most of the existing methods for evaluation of skin oxidative status and antioxidant capacity are invasive and require removal of the skin, its separation into its various layers, homogenisation, and analysis of its antioxidants or its oxidation products.…”

“…Its nature is generally descriptive and aetiology and the emission is generally understood to reflect the physiology of the human organism [1][2][3][4][5][6]. The ultraweak light emission originating spontaneously from living systems (UPE, ultraweak photon emission, biophoton emission, or short: biophotons) ranges in intensity from a few to approximately 10 2 photons / (s × cm 2 ).…”

Background: Biophoton emission is the spontaneous emission of ultraweak light emanating from all living systems, including man. The emission is linked to the endogenous production of excited states within the living system. The detection and characterisation of human biophoton emission has led to suggestions that it has potential future applications in medicine. Objectives: An overview is presented of studies on ultraweak photon emission (UPE, biophotons) from the human whole body. Methods: Electronic searches of Medline, PsychLit, PubMed and references lists of relevant review articles and books were used to establish the literature database. Articles were then analysed for their main experimental setup and results. Results: The, mostly, single case studies have resulted in a collection of observations. The collection presents information on the following fields of research: (1) influence of biological rhythms, age, and gender on emission, (2) the intensity of emission and its left-right symmetry in health and disease, (3) emission from the perspective of Traditional Chinese and Korean Medicine, (4) emission in different consciousness studies, (5) procedures for analysis of the photon signal from hands, (6) detection of peroxidative processes in the skin. Of each article the main findings are presented in a qualitative manner, quantitative data are presented where useful, and the technological or methodological limitations are discussed. Conclusion: Photon emission recording techniques have reached a stage that allows resolution of the signal in time and space. The published material is presented and includes aspects like spatial resolution of intensity, its relation to health and disease, the aspect of colour, and methods for analysis of the photon signal. The limited number of studies only allows first conclusions about the implications and significance of biophotons in relation to health and disease, or to mental states, or acupuncture. However, with the present data we consider that further research in the field is justified.

Ultra-weak photon emission (UPE) is a general feature of living -biological systems. To gain further insights into the origin of UPE and its physiological significance, the aim of the present study was to investigate the connection between hemodynamics (HD), oxygenation (OX), and UPE. Therefore, during venous and arterial occlusion (VO, AO), changes of UPE and surrogates of HD as well as OX were measured simultaneously using two photomultipliers and near-infrared spectroscopy, respectively. We showed that (1) changes in UPE correlate significantly nonlinearly with changes in oxyhemoglobin, indicating a complex association between UPE and tissue HD/OX; (2) UPE decreases significantly during AO but not during VO; (3) UPE increases significantly after AO; and (4) the view that ROS are the source of UPE is generally supported by the present study, although some findings remain unexplained in the context of the theory of ROS-mediated UPE generation. In conclusion, the present study revealed new insights into the interplay between HD, OX, and UPE and opens up new questions that have to be addressed by future studies.

“…Em circunstâncias normais, os processos fisiológicos levam à formação de radicais, resultando em emissão de fótons (na ordem de 20 a 40 contagens por s), contudo essas quantidades são muito baixas para serem detectadas por instrumentações correntemente empregadas 113 . No estresse oxidativo, os níveis de radicais são geralmente aumentados, permitindo assim sua detecção através da emissão de fotóns produzidos 35,114,115 Para a realização destes testes, os voluntários selecionados são acomodados em uma sala escura, com o equipamento de excitação e leitura sobre uma superfície do corpo previamente selecionada. Ao redor desta área o tecido é protegido com fitas adesivas hospitalares para evitar estresse desnecessário em outras regiões.…”

Recebido em 12/12/05; aceito em 13/2/06; pleblicado na web em 30/8/06 ANTIOXIDANTS IN THE SKIN: APPLICATIONS AND EVALUATION OF THEIR EFFICACY. The skin is a very complex organ, continuously exposed to physical, chemical and microbiological agents. Enzymes as well as low-molecular weight antioxidants are present in the cutaneous tissue to counterbalance the deleterious effect caused by an oxidative stress and thus maintain homeostasis. Antioxidants such as vitamins C and E, carotenoids, and extracts with these properties have been extensively used for treatment of pathologies and skin aging prevention. We review here different mechanisms that can interfere in the redox equilibrium of the skin, as well as the chemical reactions involved in these processes. Moreover, we discuss the importance of endogenous or exogenous antioxidants that can be acquired from the diet or from oral or topical administration, and methodologies that have been developed to evaluate their efficacy Keywords: skin, antioxidants; efficacy. INTRODUÇÃOA pele é um órgão complexo, formado por diferentes estruturas e com diversos tipos celulares (Figura 1), que atua como uma barreira protetora dos órgãos internos ao ambiente, enquanto mantém o balanço entre proliferação e descamação celular 1 . Mais que qualquer outro tecido, é exposta a inúmeros agentes químicos, físi-cos e microbiológicos, muitos dos quais induzem à formação de espécies reativas de oxigênio (ERO) e de nitrogênio (ERN). Estas espécies são fundamentais em diversos processos fisiopatológicos e bioquímicos, mantendo a sobrevivência e a homeostase celular, sendo que há um equilíbrio refinado entre sua formação e remoção. Porém, quando há alterações acentuadas neste equilíbrio, um estado pró-oxidante é gerado, levando assim ao chamado estresse oxidativo 2 .Neste contexto, fica claro que a pele, por sua importância, é um órgão cujas células possuem mecanismos enzimáticos de resposta rápida, bem como moléculas antioxidantes de baixo peso molecular para contrabalançar o efeito deletério causado por um estresse oxidativo
