Summary

To evaluate the effect of cold-induced stress on renal and hepatic blood flow and coagulation parameters, rabbits’ soles were exposed to ice pad (0° C). Renal and hepatic blood flow was measured after 1 h and 15 days of cold stress. Coagulation parameters (0, 8th and 15th days of stress) and histological studies were performed. Renal and hepatic blood flow was significantly reduced after cold-stress. Decreased platelet count, antithrombin III (AT III) activity, increased fibrinogen (Fbg) level, shortened activated partial thromboplastin time (aPTT) and prothrombin time (PT) was found after 8 and 15 days of cold-stress. Histology showed enlarged glomeruli with fibrin deposition in kidney, ischemic changes and fibrin deposition in liver and hemorrhagic necrosis in adrenal cortex. We conclude that undesirable localized cold induced sympathetic stimulation in daily life may be a predisposing factor for coagulopathy.
