[Oxyproline excretion in the urine in frostbite].
Hyperoxyprolinuria associated with the processes occuring in frostbitten tissues is observed in frostbites of II--III degree. In frostbites of I--II and III--IV degree the level of urine oxyproline excretion does not differ from the normal one throughout the posttraumatic period. In frostbites of I--II degree this is due to a limited volume of tissue injury, in frostbites of III--IV degree-to the fixation of decay products in the pathological focus, resulting from blood circulation disorders in the frostbitten zone. Differences in oxyprolinuria level may serve as a useful tool for differential diagnosis of frostbites.
