The purpose of this study was to examine the effect of acute (24 h) and chronic (5 wk) hypobaric hypoxic exposure equivalent to a simulated altitude of 4,300 m (446 mmHg) on the enzymes of fat metabolism. Heart, liver, and skeletal muscle were taken from 32 male Sprague-Dawley rats. Altitude exposure did not affect the activity of citrate synthase in any of the tissues, suggesting that mitochon...

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

The sympathoadrenal responses to acute and chronic hypoxic exposure at 10.5 and 7.5% oxygen were determined in the rat. Cardiac norepinephrine (NE) turnover was used to assess sympathetic nervous system (SNS) activity, and urinary excretion of epinephrine (E) was measured as an index of adrenal medullary activity. The responses of the adrenal medulla and SNS were distinct and dependent upon the...

Astronauts in space are chronically exposed particularly to high energetic protons [1]. However most of the data concerning biological effects of ionizing radiation come from studies in vitro and in vivo under acute conditions. To obtain a correct estimation of risk related to space radiation, it is necessary to compare biological damage obtained after acute and chronic irradiation. The aim of ...
