Resumo
Magnetic field is a region of space where the magnetism is manifested, due to materials with magnetic properties - called magnets. The magnetic field therapy for various types of diseases has become common. The study aims to analyze the effects of the magnetic field on the healing of soft tissue wounds made on the backs of rats. It is a quantitative experimental study using 54 male Wistar rats of 120 days, weighing 250-300g were divided into three groups (C, E1 and E2), which were made in skin wounds in his back. The animals of group E1 were kept under the influence of the north pole of a magnet with magnetic field strength of 850G. The animals of group E2 were kept under the influence of the south pole of a magnet with magnetic field strength of 850G. In each of the periods (3, 7 and 15 postoperative days) were measured macroscopically the wound areas of the back, the microscopic distance between the healthy edges from histological and counting of inflammatory cells. The results showed that over the wound area group E2 showed higher values than group C and E1 in the periods of 3 and 7 postoperative days. In the same way, values for the distance between the healthy edges for the E2 group in periods of 3 and 7 postoperative days were higher when compared to group C and E1. The count of inflammatory cells was lower in both groups E1 and E2 compared to C, but more significantly to the group E2. It can be concluded that exposure to the magnetic field arising from the use of magnets intensity 850G may modify the process of inflammation and repair of tissue in the backs of rats.
