Abstract

Male rats of Sprague-Dawley strain were subjected to low atmospheric pressures (500 and 300 mmHg)for an hour a day during 15 days. The serum protein patterns and the level of total serum proteins were determined at various time intervals during exposure. 1. When compared with control animals maintained at 760 mmHg, the low atmospheric pressure-exposed animal groups at 500 or 380 mmHg showed different changes in the serum protein patterns and the level of total serum proteins. 2. In the level of total serum preteins, a decrease resulted during the 1st day exposure of both groups, and slowly increased thereafter. From 5 to 15 days a higher steady state value than the control was obaserved. 3. In A/G ratio, the sera resulted in an increase in 1st day of both groups, and slowly decreased thereafter. From 5 to 15 days a lower steady state significantly than control value resulted. 4. Specifically, in the serum protein components, $\\beta$-globulin was increased during the experimental periods of both groups.
