Abstract
Experiments were conducted to compare the effect on wound healing of treatment with saline, or histamine diphosphate alone or combined with the application of electromagnetic (EM) fields. Surgical incisions in the skin of the dorsum of 240 rats were treated with either saline or histamine; one-half of the animals treated with each chemical were exposed to a VHF (27 MHz) EM field for 15 minutes. Surgical incisions were also made in the skin of the right scapular region in 10 dogs; one-half of the animals were treated with saline and the other half with histamine and a VHF field for 30 minutes. Histamine treatment in conjunction with EM field exposure proved most efficient in improving wound healing (rate of healing, tensile strength, minimized scar tissue); saline treatment plus EM field exposure, histamine alone and saline alone were successively less effective. The medical efficacy of EM field treatment is demonstrated, and it is noted that the greatest effort occurs within 12 hours of treatment.
