[Effect of low-frequency ultrasound on the course of the wound process]

By the methods of clinical and morphological investigations as well as by measurements of the wound medium pH it was established that the application of low-frequency ultrasound for the treatment of purulent wounds accelerated necrolysis, decreased bacterial contamination of the wound, normalised the microcirculation system, activated the macrophagal reaction, increased the proliferative and synthetic activity of fibroblasts, collagen fibrillogenesis and contributed to a sharp shortening of the hydratation phase which resulted in the earlier closing of the wound.
