| Popis: | The blood of six healthy male volunteers sampled before, immediately after, and 7 days after 5-day dry immersion was analyzed for morphological parameters, erythrocyte metabolism, and lipid and phospho-lipid levels. The experimental 5-day exposure was shown to increase the erythrocyte count. On the first day after the experiment, upward trends were exhibited by hemoglobin and packed cell volume (PCV). The significant decrease in adenosine triphosphate and low level of reduced glutathione that were also detected on the first day after the experiment could be the result of enhanced oxidation in the cell, possibly due to the activation of lipid peroxidation. A downward trend in the phospholipid fraction of the erythrocyte membrane against constant levels of cholesterol and its ethers could be associated with a significant increase in the fraction of nonesterified fatty acids on day 1 and triglycerides on days 1 and 7 after the experiment. |
