title: [Integral characteristics of heat- and electroconductivity of human skin].
abstract: Age relationships of integral parameters of heat- and electroconductivity (HC and EC) of human skin were studied. Measurements were performed in 14 body regions (Zakharyin-Gedd zones and opposite points) on 95 practically healthy women 10-63 years old. Cluster analysis of the experimental data has shown that population is evenly distributed in the space of characters. The correlation analysis permits the statement that HC and EC are practically independent parameters. At the same time the correlation coefficients for HC and EC values obtained in the opposite points are rather high. Therefore the integral parameters were introduced for describing the system: mean values (EC and HC), indices of lateral asymmetry IAEC and IAHC), nonhomogeneity indices (NIEC and NIHC). Age relationships of integral parameters and their root-mean-square deviations were computed using smoothing by the moving-average method with Gaussian weight function, whose width was optimized by the minimum of information losses. For EC and NIEC and for root-mean-square deviations of IAHC and NIHC statistically reliable changes with age are observed. They reflect the physiological state of the organism (EC and NIEC being of the leading character). The indicated integral parameters are suggested to be used for estimating the man's state at hormonal reconstructions of the organism.
