THE RELATIONSHIP BETWEEN THE DEGREES OF COLD INJURIES AND SERUM CREATINE PHOSPHOKINASE LEVELS / 解放军医学杂志

ABSTRACT

To distinguish the degrees of frostbite in early stage after freezing-thawing injuries is a most impor- tant yet difficult task. In order to seek the indicators of severity of injuries, we observed the relationship between the degrees of cold injuries and serum creatine phosphokinase (SCPK) levels. Results showed that after freezing the rabbit paws to 0℃, SCPK level began to rise. Freezing in the range of 0℃ to-25℃, SCPK levels rose inversely with the lowering of tissue temperature. The elevation of SCPK activity usually appeared 1 hr after freezing, reaching thepeak at 12 hours, and it began decline at 24 hours,returning to normal level at 72 hours after freezing.
