Reparative Processes in Soft Tissues. Influence of Acidity

Abstract

Wound treatment is one of the most actual problems of modern surgery due to the increase of degree of injury, and also due to a sharp increase in quantity of emergencies of natural and technogenic disasters. Injuries of soft tissues of various etiology are annually diagnosed in the USA more than for 30 million people. To date there is a deep theoretical base developed for understanding of a pathophysiology of wound healing process, however still many questions remain debatable. The regeneration process is characterized by high metabolic activity and is based on biochemical reactions for which the pH value is of great importance. Changes of pH values of a wound during wound healing process are reflected in article. The authors noted the influence of pH on proteases and its inhibitors activity, expression of vascular endothelial growth factor (VEGF), fibroblast activity, keratinocytes proliferation, microbial expansion, and also on wound oxygenation; in response to invasion and dissemination of microorganisms. Materials of the researches that determined pH influence degree on the skin graft survival are represented. Generalizing, following conclusions can be done: pH performs as a modulator in healing both acute chronic wounds; acidic milieu in the inflammation phase and the first half of the proliferation phase occurs to the most conducive, positively affecting on necrolysis and granulation formation; alkaline milieu in the second half of inflammation phase and in phase of epithelization  promotes early closing of the tissue defect.
