RESUMEN
The character and sequence of changes in the tissues structure of the gastrointestinal walls under the impact of the impulse and constant delivery of electric pressure with frequency 440 kHz were studied. The investigation object was squeezed, using the force, measured from 2 to 6 N/mm2. The ÐÐÐÐ-300 «Patonmed¼ apparatus was used as a source of supply. Ðlectric parameters of the process was fixed, using the analogue-numerical digital converter LCard E20-10 and laboratory oscilloscope Tektronix TDS 3014C. There was established, that electric conjunction of stomach and small intestine include three elements: destroying and disappearance of mucosa, connective tissue and membranes; fusion of the collagen fascicles and the smooth muscle cells; the loss of the collagen fascicles and the smooth muscle structure and creation of homogenous еlectric welding suture. The first two elements of the electric welding anastomosis are occurring simultaneously, but not dependent one from the other. At the welding suture completion the nondestructive changes of the tissues are spreading on a distance not more than 1 mm beyond the borders of the electrods apposition.

Significance of the tissues oedema and its elimination in the course of inflammation and the wound healing was investigated. There were analyzed the results of treatment of 68 patients, suffering inflammatory and necrotic affection of soft tissues, including 65 a lower one, 3 an upper. In 47 observations the affection course was an acute, while in 18 chronic. In 36 patients (control group) a local and systemic antibacterial therapy were conducted, and in accordance to indications surgical interventions; in 32 (main group) this treatment was added with tight bandaging of the extremity, using elastic bandage. Tight squeezing of tissues with the oedema elimination on background of an adequate antibacterial therapy and surgical sanation of purulent-necrotic focus is accompanied by arrest of infiltrative and exudative stages of an acute inflammation, promotes an active course of the inflammation proliferative stage. While treatment of chronic cutaneous defect, the application of tight squeezing have promoted the granulating shaft resolution, the granulation growth in the wound and its boundary epithelization.
