Early cutaneous reactions to local traumatization with heat in alloxan diabetic rats.

The effect of cutaneous traumatization with heat in connection with intravenous injection of Evans blue was studied in short-term alloxan diabetic rats. The effect of traumatization was dependent on the degree of traumatization. There was no difference between diabetic animals and controls. The water content of traumatized and non-traumatized skin was determined. There was no difference between diabetic animals and controls with regard to the increase in water content of traumatized skin. Histological and histochemical studies on the effect of surgical cutaneous traumatization did not reveal any differences between diabetic and non-diabetic animals. The results are compared with earlier observations in alloxan diabetic animals with and without ketosis and in long-term diabetes.
