Time course of rat peritoneal temperature before, during, and after treatment (TC, AIH, and dAIH + AIH). Absolute values of average baseline temperature (1 h) were similar in all treatment groups: AIH, 37.4 ± 0.1°C; dAIH + AIH, 37.6 ± 0.1°C; TC, 37.4 ± 0.1°C. Peritoneal temperatures prior to the 6th episode of hypoxia and 40–60 min after treatment were not significantly different among groups. After the 6th hypoxic episode, peritoneal temperature in AIH and dAIH + AIH groups had significantly decreased relative to TC rats, but these values had returned to TC levels by 40–60 min post-AIH. All variables in the dAIH + AIH group were obtained on the last day of AIH exposure (day 8). Values are means ± SE. *Significantly different from TC; †significantly different from baseline; P < 0.05.
