Elements of wound healing | Methods | ||
---|---|---|---|
HBOT | MT | PRPT | |
Inflammation | Bactericidal and bacteriostatic effects on both aerobic and anaerobic bacteria through the action of the super oxide enzyme* | Antibacterial potential effect of alkaline pH of maggot secretion [77, 78] Wound bacteria are killed as they pass through the maggot's digestive tract* Presence of a potent bactericide present in maggot secretions* Cytokine regulation and enhanced phagocytosis [75] |
Suppresses cytokine release and limits the amount of inflammation, interacting with macrophages to improve tissue healing Enhances phagocytosis and chemotaxis [54]* Antimicrobial host defence enriched with growth factors and other active substances [83]* |
| |||
Granulated tissue formation—epithelialization | Increases epidermal cells and fibroblast proliferation and differentiation [29] | The healing of wounds is an interactive process (regulators as growth factors, cytokines and chemokines) [42] Synthesized and released locally proteins or polypeptides [42, 43] Increases fibroblast proliferation through maggots excretions and secretions [75] |
Influences on chemotaxis, mitogenesis, and differentiation Promotes healing by stimulating fibroblast and keratinocyte proliferation Promotes granulation tissue formation [55, 61]* and epithelialisation |
| |||
Matrix formations | Increases fibroblast proliferation and collagen production | Stimulates extracellular matrix and remodeling processes [45] | Stimulates the deposition of extracellular matrix and collagen [56]* |
| |||
Angiogenesis | The oxygen gradient promotes the formation of new vessels required for wound healing [28, 35, 68] | Growth factors, cytokines, and chemokines provide significant vasodilation and increased capillary permeability to the wound site, allowing the infusion of recruited polymorphonuclear leucocytes (PMNs) and macrophages [48, 84] | Promotes new capillary growth [55, 56]* |
