Serum levels of tumor necrosis factor-α (TNF-α), intercellular adhesion molecule-1 (ICAM-1), and interleukin-10 (IL-10) for NT rats, (VEH+HS) rats, and (KYNA+HS) rats. The samples were obtained at 85 min after the initiation of heat exposure in heatstroke rats or the equivalent times in NTs group. bP<0.05, in comparison with NT group; eP<0.05 in comparison with (VEH+HS) group. All heatstroke group had heat exposure (43 °C) withdrawn exactly at 68 min and were then allowed to recover at room temperature (26 °C). Bars were the mean±SD of six rats for each group.
