Simulated microgravity affects carrageenan-induced inflammation process in rats
Weightlessness significantly impacts physiological systems.

| Summary: | Weightlessness significantly impacts physiological systems. In the current study, we investigate the effects of 7 days exposure of rats to simulated microgravity (using a modified rat-modeled random positioning machine, working with four experimental animals simultaneously) on local carrageenan-induced inflammation and serum levels of liver enzymes, metabolites (glucose, urea, creatinine), and metabolic hormones (thyroid-stimulating hormone - TSH, aldosterone, cortisol). Male Wistar rats (n=12, m=200 ± 20 g) were evenly divided into RPM (experimental) and RPM-K (control) groups. The RPM rats showed a notable mass decrease compared to the controls. A significant increase in the carrageenan-induced inflammatory response was reached on the 24th hour in the RPM group compared to the RPM-K. Simulated microgravity resulted in lower serum glucose, creatinine, cortisol, and elevated urea levels. In conclusion, 7 days of exposure to random positioning machine-simulated microgravity promotes a pro-inflammatory state, potentially affecting insulin sensitivity, glucose utilization, and muscle catabolism. |
