Creatine kinase activity in suicide by burning.

In the course of a systematic study of serum enzymes activities from muscular tissues, applied to fifty six burnt patients taken at random, the authors have observed a significant and isolated raised of serum CPK in six burnt people when they were admitted to hospital. There were no known causes of raised CPK essentially due to muscular isozyme. The only common point between those six persons is that they all attempted to commit suicide by burning.
