Abstract

This article, based on a report presented at the Scientific Session of the Russian Academy of Sciences, highlights the history of the formation of space medicine, its theoretical foundations, and the role of scientists of the Academy of Sciences in the preparation and implementation of the first manned flight into space. The achievements of domestic specialists in space physiology, biology, and medicine promoting the development of manned cosmonautics are considered. Examples are given of the implementation of the results of space research, as well as instruments and devices for medical support of space crews, into practical health care. The problems of medical support of future interplanetary flights and the ways of their solution are analyzed.

Abstract

A rationale for the concept and strategy of monitoring of the atmospheric chemical composition and water quality are provided for manned spacecraft to be used for long-term and interplanetary flights. The main risk factors are formulated for a change in atmospheric and water composition during interplanetary space flights. A promising version of the analytical system for operational control of air and water quality in manned spacecraft is described considering these risk factors. Several gas analysis methods are proposed to be used in this system to partially overlap the nomenclature of detected species with respect to particularly important (critical) species. The water quality in the system is monitored by two instruments: one for measuring the total carbon content and the other for analyzing the ionic composition of water. [ABSTRACT FROM AUTHOR]

Abstract

Calcium metabolism, its hormonal regulation and renal calciuretic function were investigated in 20 healthy volunteers during 120- and 182-day head-down tilt studies. The content of total and ionized calcium and parathyroid hormone was found to increase during the study. The concentration of calcitonin increased at an early stage of exposure and decreased thereafter. This resulted in negative calcium balance which was on the average 5, 6g per month. Measurements of iliac bone biopsies showed calcium decrease and phosphorus increase.
