Chronic Ulcers

: Nitric oxide (NO) is a promising pharmaceutical component that has vasodilator, antibacterial and wound healing activity. Chronic ulcers are non-healing disorders that are generally associated with distortion of lower limbs. Among the severe consequence’s derivative of these diseases, are the problems of chronic wound progression. NO which is categorized as smallest gaseous neurotransmitter has beneficial effects in different phases of chronic inflammation. Defensive mechanism of NO is found useful in several severe conditions such as gestational healing, gastrointestinal healing and diabetic healing. The current review presents up to date collection of literature about role of NO in chronic ulcers due to the prevalence of diabetes, DPN, and diabetic foot ulcers, and because of the lack of available effective treatments to directly address the pathology contributing to these conditions, novel treatments are being sought. This review also collects the information about deficiency of NO synthase in diabetic patients leads to a lack of vascularization of the peripheral nerves, which causes diabetic neuropathy; and this could be treated with vasodilators such as nitric oxide. Apart from pharmacological mechanism of NO, the article also reviewed and analyzed to elucidate the potential of a transdermal delivery of NO for the treatment of chronic ulcers.

Diabetic Wound Healing

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.

Beneficial Effects

Over the years strong evidence has been accumulated showing that aerobic physical exercise exerts beneficial effects on the prevention and reduction of cardiovascular risk. Exercise in healthy subjects fosters physiological remodeling of the adult heart. Concurrently, physical training can significantly slow-down or even reverse the maladaptive pathologic cardiac remodeling in cardiac diseases, improving heart function. The underlying cellular and molecular mechanisms of the beneficial effects of physical exercise on the heart are still a subject of intensive study. Aerobic activity increases cardiovascular nitric oxide (NO) released mainly through nitric oxidase synthase 3 activity, promoting endothelium-dependent vasodilation, reducing vascular resistance, and lowering blood pressure. On the reverse, an imbalance between increasing free radical production and decreased NO generation characterizes pathologic remodeling, which has been termed the “nitroso-redox imbalance”. Besides these classical evidence on the role of NO in cardiac physiology and pathology, accumulating data show that NO regulate different aspects of stem cell biology, including survival, proliferation, migration, differentiation, and secretion of pro-regenerative factors. Concurrently, it has been shown that physical exercise generates physiological remodeling while antagonizes pathologic remodeling also by fostering cardiac regeneration, including new cardiomyocyte formation. This review is therefore focused on the possible link between physical exercise, NO, and stem cell biology in the cardiac regenerative/reparative response to physiological or pathological load. Cellular and molecular mechanisms that generate an exercise-induced cardioprotective phenotype are discussed in regards with myocardial repair and regeneration. Aerobic training can benefit cells implicated in cardiovascular homeostasis and response to damage by NO-mediated pathways that protect stem cells in the hostile environment, enhance their activation and differentiation and, in turn, translate to more efficient myocardial tissue regeneration. Moreover, stem cell preconditioning by and/or local potentiation of NO signaling can be envisioned as promising approaches to improve the post-transplantation stem cell survival and the efficacy of cardiac stem cell therapy.

Diabetic Wound Healing

The integration of several cellular responses initiates the process of wound healing. Matrix Metalloproteinases (MMPs) play an integral role in wound healing. Their main function is degradation, by removal of damaged extracellular matrix (ECM) during the inflammatory phase, breakdown of the capillary basement membrane for angiogenesis and cell migration during the proliferation phase, and contraction and remodelling of tissue in the remodelling phase. For effective healing to occur, all wounds require a certain amount of these enzymes, which on the contrary could be very damaging at high concentrations causing excessive degradation and impaired wound healing. The imbalance in MMPs may increase the chronicity of a wound, a familiar problem seen in diabetic patients. The association of diabetes with impaired wound healing and other vascular complications is a serious public health issue. These may eventually lead to chronic foot ulcers and amputation. Low intensity laser irradiation (LILI) or photobiomodulation (PBM) is known to stimulate several wound healing processes; however, its role in matrix proteins and diabetic wound healing has not been fully investigated. This review focuses on the role of MMPs in diabetic wound healing and their interaction in PBM.

Treatment Of Diabetes

Metformin (MTF) is a widely used drug for the treatment of diabetes mellitus type 2 (DM2) and frequently used as an adjuvant therapy for polycystic ovarian syndrome, metabolic syndrome, and in some cases also tuberculosis. Its protective effect on the cardiovascular system has also been described. Recently, MTF was subjected to various analyzes and studies that showed its beneficial effects in cancer treatment such as reducing cancer cell proliferation, reducing tumor growth, inducing apoptosis, reducing cancer risk in diabetic patients, or reducing likelihood of relapse. One of the MTF’s mechanisms of action is the activation of adenosine-monophosphate-activated protein kinase (AMPK). Several studies have shown that AMPK/mammalian target of rapamycin (mTOR) pathway has anticancer effect in vivo and in vitro. The aim of this review is to present the anticancer activity of MTF highlighting the importance of the AMPK/mTOR pathway in the cancer process.
