This study investigates oxidative stress and antioxidant responses in rat brain regions during hypoxia, suggesting significant impacts of altitude exposure.
Key Points
Exposure to high-altitude hypoxia increases oxidative stress, impacting brain regions in rats.
Reactive oxygen species and malondialdehyde levels rose, while antioxidant catalase decreased significantly.
Effects were particularly evident in the hippocampus, cortex, and striatum, highlighting vulnerability at extreme altitudes.
Findings emphasize the need for understanding hypoxia's impacts on brain homeostasis and health risks.
