Study of Autonomic Imballance at the Meteorological Changes by Multivariate Analysis

[摘要] Applying factor analyses, one of multivariate analyses, to tests of several biological functions, the author seeked for variation of linear transformed variates of tests when cold fronts passed through. From the previous observations on individuals, two independent components were extracted as function units. These and those components exhibited the particular mode of change during front passing as a whole. The 1st component, consisted of body temperature and heart beat interval, reduced markedly on frontal days and increased after front passing. The 2nd component, which was independent to the 1st component and refered to blood pressure, increased gradually at the course of front passing.Since in this observation each component consisted of at least two characteristics and simultaneous changes of the constituents were amalgamated into one variate, these results bases on the multivariate method seems to explain more precisely the biological regulation mechanism than the results obtained from single characteristic.The correlation between each component and common meteorological factors was almost negligible. To obtain significant figures between meteorological and biological processes, synthetic characteristic of cold front and other meteorological conditions should be taken into consideration.
