[Evaluation of adaptation of animals to hypoxic hypoxia by the multiple regression method]. 1984

V V Kustov, and V G Litau, and Iu A Kukushkin, and S M Razinkin

White mice were exposed to hypoxic hypoxia during 30 days. In the study a correlation between the altitude ceiling and various physiological parameters (body weight, body temperature variations in response to a cold stress (5 degrees C), hemoglobin content, coefficients of adaptive oxygen consumption determined as the ratio of oxygen consumption at 6000 m to that at sea level (K1) and the ratio of oxygen consumption in hypoxic environment to that in a normoxic atmosphere (K2) was established. The data obtained allow the conclusion that the multiple regression method can be used for measuring objectively the tension of regulatory systems and for discriminating stages of animal adaptation to hypoxic hypoxia.

D010101	Oxygen Consumption	The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body.

D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D006454	Hemoglobins	The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates.

D000531	Altitude	A vertical distance measured from a known level on the surface of a planet or other celestial body.	Altitudes
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
