title: [Hypobaric hypoxia and catecholaminuria in normal humans].
abstract: Consequences of hypoxic hypobaric chemostimulation have been analyzed in six normal subjects arriving in excellent ambient conditions in a mountain scientific station (Jungfraujoch, 3,580 m). During the first two days of the sojourn, neither systemic blood pressure, nor catecholamines urinary excretion were modified in comparison with their values at the sea level. It is concluded that the chemostimulation due to hypobaric hypoxia does not affect orthosympathetic activities as far as other stressing solicitations are avoided (muscular exercise, temperature modifications, psychic alertness...etc.).
