Vital reactions to frostbite in the paw and ear skin of guinea pigs were studied in order to find an animal model for frostbite in cases of accidental hypothermia. One group of animals was rendered hypothermic (rectal temperature, 30 degrees C) by exposure to an ambient temperature of -20 degrees C,
Vital reactions in the paw skin of guinea pigs dying of hypothermia were examined using a variety of histochemical methods to find ways of distinguishing between ante-mortem and post-mortem frostbites. Some animals were treated with ethanol or diazepam. Edema, hyperemia, and incipient accumulation
Eleven frostbites were induced on the ears of seven New Zealand White rabbits and specimens were taken from the lesion after 1, 4 and 8 hours, and from ten further frostbites on the ears of six rabbits for examination 1, 3 and 7 days later. The specimens were taken at the border between the frozen
