The Effects of Difference in lntensity of Ultraviolet and Infrared Irradiation on Human Physiological Polymorphism

(1)通过野外受试者实验，研究了太阳紫外线对人体的影响。对受试者进行了太阳光(紫外光)照射和衣物防晒实验，并对结果进行了比较。紫外线照射3小时后，NK细胞活性下降，IL-6水平升高，说明紫外线对机体免疫系统有一定的影响。在太阳光照射下，交感神经系统变得活跃。暴露后，人体的热量损失变得很大，皮肤上出现了明显的红斑。在香港以香港本地人为研究对象进行了相同的实验，并对日本人和香港人的实验结果进行了比较。(2)进行了人工紫外线光源对人体影响的实验研究。以维生素Lite为光源，观察免疫系统反应、自主神经系统反应和主观评价使用和不使用紫外线切割膜的效果更好。在本实验中，没有检测到紫外线对免疫系统和自主神经系统活动的显著影响，但发现了夜间睡眠的碎裂，这表明紫外线对人体有一定的影响。(3)以无毛小鼠为实验对象，研究了紫外线对动物活动、体温节律、免疫器官和内分泌器官的影响。由于人工紫外光强度较弱，对免疫和内分泌器官的影响不明显，但在活动节律方面，UV有抑制活动程度、增强活动节律的趋势。(4)在日本(奈良)和香港进行了太阳紫外线(UVA、UVB)和入射太阳辐射量的观测，并调查了它们的季节变化。香港的UVA、UVB和入射太阳辐射量分别是日本的1.7-4倍、1.1-1.7倍和1.2-2.1倍。讨论了辐射量与纬度、臭氧质量的关系。(5)利用自行研制的紫外线屏蔽仪对服装面料的紫外线屏蔽性能进行了评价。研究了测试条件、织物结构和纤维材料对测试结果的影响。利用光纤型UV/VIS光谱仪，对不同纤维材料制成的灰色织物的光谱透过率和反射率进行了测试，并与染色织物进行了比较。较少

(1) The effect of solar UV on human body was investigated by field test using subjects. The experiment that subjects were exposed to solar light (UV light) and subjects were protected from UV by clothing was carried out, and results were compared. For the subjects exposed to UV for 3 hr, the activity of NK cells decreases and amount of IL-6 increases, and these facts indicate that the effects of UV on immune system. During exposure to solar light, the sympathetic nerve system becomes active. After exposure, heat loss from human body becomes high, and erythema is detected significantly on skin. The same experiment were carried out using Hong Kong native people as subjects in Hong Kong, and the results were compared between Japanese and Hong Kong people.(2) The experiment to investigate the effects of artificial UV light source on human body was carried out. Using vita-lite as light source, the response of the immune system, the autonomous nervous system and subjective evaluation were me … More asured with and without UV cut film. In this experiment, the significant effects of UV on the activity of the immune system and the autonomous nervous system were not detected, however, fragmentation of sleep in the night was recognized, and this fact indicates that there are some influences of UV on human body.(3) The effects of UV on animal activity, body temperature rhythm, immune organs and endocrine organs were investigated using hairless mice. Because of weak intensity of artificial UV light, the effects on immune and endocrine organs were not detected significantly, however, as for rhythm in activity, the tendency that UV restrains the degree of activity and enhances the rhythm in activity is recognized.(4) Observation of amount of solar UV rays(UVA, UVB) and incident solar radiation was carried out in Japan(Nara)and Hong Kong, and their seasonal change were investigated. Amount of UVA, UVB and incident solar radiation in Hong Kong are 1.7-4, 1.1-1.7, 1.2-2.1 times high compared to Japan, respectively. The relation between amount of radiation and latitude, ozone mass are discussed.(5) The UV shielding properties of fabrics of clothing use were evaluated using the apparatus we developed. The effect of measurement condition, fabric construction and fiber materials were investigated. Using UV/vis spectrophotometer of optical fiber type, spectral transmittance and reflectance of fabrics in grey state made of various fiber materials were measured and the results were compared with dyed fabrics.
