Effects of Ibuprofen during Exertional Heat Stroke in Mice

Purpose We hypothesized that IBU would exacerbate intestinal injury, reduce exercise performance, and increase susceptibility to heat stroke. Methods To test this hypothesis, we administered IBU via diet to male and female C57/BL6J mice, over 48 h before EHS. Susceptibility to EHS was determined by assessing exercise response using a forced running wheel, housed inside an environmental chamber at 37.5°C. Core temperature (Tc) was monitored by telemetry. Mice were allocated into four groups: exercise only (EXC); EHS + IBU; EXC + IBU; and EHS only. Exercise performance and Tc profiles were evaluated and stomachs, intestines and plasma were collected at 3 h post-EHS. Results The EHS + IBU males ran approximately 87% longer when Tc was above 41°C (P
