Cooling therapy upregulates protein C activation in heat stressed rats: An experimental study

Protein C (PC) pathway homeostasis is implicated in heat stress (HS). This study determines whether cooling could improve the PC pathway in HS. Fifty‐six anesthetized rats were warmed to achieve HS (rectal temperature [Tr] 42°C). These rats were divided into seven groups: (a) control group:sacrifice...

Zusammenfassung:Protein C (PC) pathway homeostasis is implicated in heat stress (HS). This study determines whether cooling could improve the PC pathway in HS. Fifty‐six anesthetized rats were warmed to achieve HS (rectal temperature [Tr] 42°C). These rats were divided into seven groups: (a) control group:sacrifice immediately 15 min after HS; (b) HS+I:sacrifice immediately after 15 min ice‐water treatment or (c) 3 hr after HS; (d) HS+C:sacrifice immediately after 15‐min cold‐water treatment or (e) 3 hr after HS; (f) HS: sacrifice immediately 15 min after HS or (g) 3 hr after HS. Plasma PC, activated protein C (APC), and soluble thrombomodulin (sTM) levels were tested at both time points. After cooling, Tr in the HS+I and HS+C groups significantly decreased, when compared with the HS group, and Tr was significantly lower in the HS+I group than in the HS+C group ( p
