JOURNAL FREE ACCESSBiometeorology can defined as an interdisciplinary academic field involving from biological mechanism to environmental phenomena based on ecology. Moreover, it includes environmental planning from the living and social aspects of view. Consequently, one of the further direction in this field should orient to the application of knowledge of biological adaptability to climate and interaction between an organism and its environment to biosphere planning for the sustainable global environment.View full abstractDownload PDF (544K) -

JOURNAL FREE ACCESSRecent global environmental problems such as global warming, acid rain, depletion of the ozone layer, desertification and El Nino are directly and indirectly connected with biometeorological phenomena in respect to the cause and effect of environmental problems. Except the desertification which brings about deforestation, it is no exaggeration to say that most influences of global environmental problems are biometeorological. Nevertheless, it seems that biometeorology dose not give so full play to global environmental studies. It is recognized in both papers' number of Japanese Society of Biometeorology during recent three decades and that of International Society of Biometeorology during recent twenty years. In common to internal and external society, symposiums on global environment are not so few althogh there are not many personal original studies.View full abstractDownload PDF (578K) -

JOURNAL FREE ACCESSBiometeorology deals with the effect of meteorological phenomenon on biological matter, especially on living. Meteorological phenomenon as one of the main factors in the environments affects the living directly or via the changes of the other environments. Since both of living and environment are markedly time-dependent, 4 dimentional studies are indispensable in the field of biometeorology. From this aspect, presented are some analyses which have shown the effects of meteorological phenomena on symptomatological matters of such diseases as allergic rhinitis and/or conjunctivitis and bronchial asthma that closely relate with environment.View full abstractDownload PDF (669K) -

JOURNAL FREE ACCESSTo determine the effects of high temperature on pulmonary antibacterial defense, mice were placed in animal chambers at 23°C, 32°C, and 35.5°C for 14 days. Rectal temperature averaged 36.9°C at 23°C, 37.6°C at 32°C, and 38.9°C at 35.5°C from days 1 to 14. In comparison to the 23°C group pulmonary bactericidal activity against Staphylococcus aureus and Proteus mirabilis was significantly suppressed on day 14 in the 35.5°C group but not in the 32°C group. The number of alveolar macrophage (Alveolar Mφ) in the BAL fluid of the non bacterially challenged mice decreased significantly after exposure to 35.5°C, but the number of polymorphonuclear neutrophils (PMNs) did not change. It is well known that killing of S. aureus in the lung depends on resident alveolar Mφ, and the killing of P.mirabilis depends on both alveolar Mφ and PMNs which migrate into the alveoli. Pulmonary bactericidal activity against S. aureus and P. mirabilis was suppressed at 35.5°C, which was associated with changes in the phagocyte system including alveolar Mφ and PMNs. This fact suggests a depressed ability of the host to defend against respiratory infection. The concentration of total protein and albumin or LDH activity in BAL supernatant did not change at high temperature. Therefore, it seems that the increase of permeability of alveolar-blood vessels and the injury of pulmonary epithelial cells were not occured by high temperature.View full abstractDownload PDF (839K) -

JOURNAL FREE ACCESSWe propose “Mean Clothing Microclimate (MCM) ” in the present study. The purpose of this study was to obtain the new formula for MCM. The subjects were six healthy young adult females. We prepared two clothing conditions, namely, winter sportswear (0.89 do) and summer sportswear (0.23 do) . The measurement points were 27 and 17, respectively. Microclimate clothing temperature and humidity were observed. The climatic chamber was controlled at 10°C, 30°C (for winter sportswear) and 20°C, 30°C (for summer sportswear) . The relative humidity was fixed at 50%. The work load increased gradually from rest to RMR2.0 level. As a results, the following formulas were obtained, that is, MCM=0.38 ventral abdomen+0.20 dorsal elbow+0.42 dorsal thigh (for winter sportswear) and MCM=0.48 dorsal abdomen+0.26 dorsal shoulder+0.26 ventral thigh (for summer sportswear) . Finally, we discussed from viewpoints of the accuracy of formula, comparison with the other thermal evaluation indexes and correlation between MCM value and subjective sensation.View full abstractDownload PDF (883K)
