[The seasonal characteristics of the circadian rhythm of hypoxic resistance and convulsive resistance].
Hypoxic and convulsive resistances have daily rhythms, the pattern of which depends on the year season. Latent period of occurrence of epileptic seizures and time of life at the "height" of 11,000 m above the sea level undergo similar changes in autumn and spring. In winter minimal similarity between daily dynamics of each of these resistances and analogous ones in other seasons is observed, but rhythms of tolerance to hypoxia are maximally synchronized with the rhythms of convulsive resistance. In autumn hypoxic and convulsive resistances are minimal. Maximums of these indices are observed in different seasons: for tolerance to hypoxia it is summer, for convulsive resistance--spring.
