Corrente elétrica positiva alternada no tratamento de feridas cutâneas de camundongos

Abstract

Thirty six female mice had been used to study the repairing of cutaneous wounds which was treated with seven minute electric stimulation of 2mA a day, by using the transcutaneuos kinesis stimulator. They had been distributed in three groups of equal number, being subdivided in sub-groups which have been named: controlled (I) and treatment (II). The animals had been submitted to the circular removal of skin of 10,0mm in the dorsal region of the thorax and the wounds had been evaluated in 7th, 14th and 21th days of postoperative (PO). The reduction area of the wounds of the treated sub-group significantly did not surpass the area related to wounds of the controlled subgroup. In the wounds of the controlled group, it was observed innumerable sanguineous vases, intense hemorrhages, intense presence of fibroblasts, moderate of plasmocytes and polymorfonuclears. In the ones of the treated animals dermal and the epidermis met thin with bigger amount of polymorfonuclears. The administration of 2mA, during seven minutes, in cutaneous wound of mice induces the formation of a dermal and thin epidermis. The final aspect of the scar of the wounds of the treated and controlled animals was distinctly similar.
