Therapeutic Role of Nitric Oxide in Diabetic Wound Healing: A Systematic Review

Abstract

Post injury, healing of wound is essential for recovery of uprightness of the body, which is one of the complex, continuous and unanticipated chains of events in case of diabetic patients. Nitric oxide represents a potential wound therapeutic agent due to its ability to regulate inflammation and eradicate bacterial infections. Impaired wound healing is a prominent diabetic complication which may lead to amputations also. In addition to modern medicines we can use nitric oxide therapy prominently for diabetic wound healing. Prominent and proven role of nitric oxide as well as conventional materials (like metformin and hydrogen sulphide, whey proteins, acidified nitrile etc), therapies (like low level laser therapy, hyperbaric oxygen therapy etc) and techniques (like in vivo implants with biosensors) can be taken into consideration. Many plant extracts showed promising results for wound healing activity by increasing nitric oxide levels. Use of modern technologies such as implant with biosensor and technique like sonic head hog gene are available for diabetic wound healing using Nitric oxide. In this review, an attempt has been made to compile comprehensive updated information of role of nitric oxide in diabetic wound healing, which may be exploited by focusing more on development of effective strategies to treat diabetes-associated wound.
