A Brief Summary of the Science
by Dr. Tracey Sturgill, DVM, University of Georgia
The majority of wound healing research has been performed for human medicine. Additional research in veterinary species,1-3 including the horse,4 indicates that mammalian species heal in a similar fashion. Normal healing requires a balancing act between the removal of dead tissue and the construction of new tissue. This involves a precise interaction between numerous cell types, as well as growth factors, enzymes and cytokines for normal healing to proceed.4,5 The normal healing process should proceed as in the diagram below.
Chronic wounds are due to an imbalance in the healing process. Matrix metalloproteinases (MMP) and their inhibitors, (tissue inhibitors of metalloproteinases (TIMPs)) are key for this process to occur in the horse6 as well as the human.5 In the normally healing wound, various MMPs are expressed throughout the healing process7. In chronic wounds, MMP/TIMP imbalances decrease healing. Naturally occurring cations, such as Potassium, Rubidium, Calcium, and Zinc, have been shown to alter the expression of over 10,000 genes, regulate protease imbalances, down-regulate the production of reactive oxygen species (ROS) which can damage other molecules and the cell structures of which they are a part, and stimulate re-epithelialization.8,9
