Abstract

The laser, ultrasound, and electrical current energies are widely applied in the healing processes as well as in many other therapeutic applications in medicine. This study was established to evaluate the role of laser, ultrasound, and electric current on the wounds healing process and compare the results according to histological parameters of healing. Forty eight male mice of 20-25 gm in weight were randomly subdivided into four groups of twelfth animals each as follows: Laser group, ultrasound group, electrical current group, and control group. A one centimeter linear incision was made on the shaved backs of all mice. Group 1 had given continuous diode laser with a wavelength of 637 nm, 250 mW power. 2 Group 2 had treated with 1 MHz ultrasound frequency, 0.5 W/cm intensity. Group 3 had submitted to pulsed biphasic rectangular current of 30 Hz frequency, 1 mA current. Group 4 was kept as control. The treatments were applied at the same day, three sessions/week, for two weeks. The results were collected and compared histologically for certain days during the healing process. This study showed that, both electric current treatment and laser treatment have beneficial effects in the inflammatory and proliferation phases of wound healing, as compared with ultrasound treated group and control group.
