Abstract
Significance: Carbon monoxide (CO) is an endogenous gaseous mediator that plays an important role in maintaining gastrointestinal (GI) tract homeostasis, acting in mucosal defense, and providing negative modulation of pathophysiological markers of clinical conditions. Recent Advances: Preclinical studies using animal models and/or cell culture show that CO can modulate the inflammatory response and oxidative stress in GI mucosal injuries and pathological conditions, reducing proinflammatory cytokines and reactive oxygen species, while increasing antioxidant defense mechanisms. Critical Issues: CO has potent anti-inflammatory and antioxidant effects. The defense mechanisms of the GI tract are subject to aggression by different chemical agents (e.g., drugs and ethanol) as well as complex and multifactorial diseases, with inflammation and oxidative stress as strong triggers for the deleterious effects. Thus, it is possible that CO acts on a variety of molecules involved in the inflammatory and oxidative signaling cascades, as well as reinforcing several defense mechanisms that maintain GI homeostasis. Future Directions: CO-based therapies are promising tools for the treatment of GI disorders, such as gastric and intestinal injuries, inflammatory bowel disease, and pancreatitis. Therefore, it is necessary to develop safe and selective CO-releasing agents and/or donor drugs to facilitate effective treatments and methods for analysis of CO levels that are simple and inexpensive.

Topical application of sustained released-carbon monoxide promotes cutaneous wound healing in diabetic mice. Biochem Pharmacol 2022; 199:115016.

Abstract
Clinical incidences of pressure ulcers in the elderly and intractable skin ulcers in diabetic patients are increasing because of the aging population and an increase in the number of diabetic patients worldwide. Although various agents are used to treat pressure and skin ulcers, these ulcers are often refractory and deteriorate the patients' quality of life. Therefore, a novel therapeutic agent with a novel mechanism of action is required. Carbon monoxide (CO) contributes to many physiological and pathophysiological processes, including anti-inflammatory activity; therefore, it can be a therapeutic gaseous molecule. Recent studies have revealed that CO accelerates wound healing in gastrointestinal tract injuries. However, it remains unclear whether CO promotes cutaneous wound healing. Therefore, we aimed to evaluate the therapeutic effects of topical application of a CO-containing solution and elucidate the underlying mechanism. A full-thickness skin wound generated on the back of diabetic mice was treated topically with CO or vehicle. Sustained release of CO was achieved using polyacrylic acid (PAA) as a thickener. The administration of CO-containing PAA aqueous solution resulted in a significant acceleration in wound recovery without elevating serum CO levels in association with increased angiogenesis and supported by elevated expression of vascular endothelial growth factor mRNA in the wound granulomatous tissues. These data suggest that CO might represent a novel therapeutic agent for the treatment of cutaneous wounds.

Abstract
Nature has endowed gaseous molecules such as O2, CO2, CO, NO, H2S, and N2 with critical and diverse roles in sustaining life, from supplying energy needed to power life and building blocks for life's physical structure to mediating and coordinating cellular functions. In this article, we give a brief introduction of the complex functions of the various gaseous molecules in life and then focus on carbon monoxide as a specific example of an endogenously produced signaling molecule to highlight the importance of this class of molecules. The past twenty years have seen much progress in understanding CO's mechanism(s) of action and pharmacological effects as well as in developing delivery methods for easy administration. One remarkable trait of CO is its pleiotropic effects that have few parallels, except perhaps its sister gaseous signaling molecules such as nitric oxide and hydrogen sulfide. This review will delve into the sophistication of CO-mediated signaling as well as its validated pharmacological functions and possible therapeutic applications.

Rectal administration of carbon monoxide inhibits the development of intestinal inflammation and promotes intestinal wound healing via the activation of the Rho-kinase pathway in rats.

Abstract
The inhalation of carbon monoxide (CO) gas and the administration of CO-releasing molecules were shown to inhibit the development of intestinal inflammation in a murine colitis model. However, it remains unclear whether CO promotes intestinal wound healing. Herein, we aimed to evaluate the therapeutic effects of the topical application of CO-saturated saline enemas on intestinal inflammation and elucidate the underlying mechanism. Acute colitis was induced with trinitrobenzene sulfonic acid (TNBS) in male Wistar rats. A CO-saturated solution was prepared via bubbling 50% CO gas into saline and was rectally administrated twice a day after colitis induction; rats were sacrificed 3 or 7 days after induction for the study of the acute or healing phases, respectively. The distal colon was isolated, and ulcerated lesions were measured. In vitro wound healing assays were also employed to determine the mechanism underlying rat intestinal epithelial cell restitution after CO treatment. CO solution rectal administration ameliorated acute TNBS-induced colonic ulceration and accelerated ulcer healing without elevating serum CO levels. The increase in thiobarbituric acid-reactive substances and myeloperoxidase activity after induction of acute TNBS colitis was also significantly inhibited after CO treatment. Moreover, the wound healing assays revealed that the CO-saturated medium enhanced rat intestinal epithelial cell migration via the activation of Rho-kinase. In addition, the activation of Rho-kinase in response to CO treatment was confirmed in the inflamed colonic tissue. Therefore, the rectal administration of a CO-saturated solution protects the intestinal mucosa from inflammation and accelerates colonic ulcer healing through enhanced epithelial cell restitution. CO may thus represent a novel therapeutic agent for the treatment of inflammatory bowel disease.

Abstract
Heme Oxygenase 1 (HMOX1) is an enzyme that catalyzes the reaction that degrades the heme group contained in several important proteins, such as hemoglobin, myoglobin, and cytochrome p450. The enzymatic reaction catalyzed by HMOX1 generates Fe2+, biliverdin and CO. It has been shown that HMOX1 activity and the by-product CO can downmodulate the damaging immune response in several models of intestinal inflammation as a result of pharmacological induction of HMOX1 expression and the administration of non-toxic amounts of CO. Inflammatory Bowel Diseases, which includes Crohn's Disease (CD) and Ulcerative Colitis (UC), are one of the most studied ailments associated to HMOX1 effects. However, microbiota imbalances and infections are also important factors influencing the occurrence of acute and chronic intestinal inflammation, where HMOX1 activity may play a major role. As part of this article we discuss the immune modulatory capacity of HMOX1 during IBD, as well during the infections and interactions with the microbiota that contribute to this inflammatory disease.

Abstract
Redox-related gaseous molecular species in the gastrointestinal tract are derived from the chemical oxidation-reduction reactions, enzymatic reactions, swallowing, and bacterial production. Recent studies have demonstrated the crucial roles of the microbiota and gaseous molecules in the pathogenesis of gastrointestinal inflammatory and functional diseases. Especially in the hypoxic condition of the large intestine, various bacteria produce acetic acid, methane, and hydrogen sulfide using hydrogen molecules generated by the fermentation reaction as an energy source. In this review, we summarized the recent advances in the biology of redox-related gaseous molecules in the gastrointestinal tract.

Abstract
Recent studies have identified carbon monoxide (CO) as a potential therapeutic molecule for the treatment of inflammatory diseases including intestinal inflammation. In the present study, we explored the efficacy and the mechanisms of action of CO-releasing molecule (CORM)-A1 in T-cell transfer induced colitis model in mice. In addition, the impact of CORM-A1 on the T helper (Th) cell differentiation was evaluated using naïve CD4+ T cells isolated from the spleens in Balb/c mice. The results showed that CORM-A1 conferred protection against the development of intestinal inflammation and attenuated Th17 cell differentiation. Hence, the observed immunomodulatory effects of CORM-A1 could be useful for developing novel therapeutic approaches for managing intestinal inflammation through the regulation of Th17 differentiation.

Abstract
Ulcerative colitis (UC) is a kind of chronic inflammatory disease and its etiology and pathogenesis are not clear. Accumulating evidence has indicated that the interactions among genotype, immune system and intestinal microbiota of patients play a significant role in the pathogenesis of UC. At present, it is difficult to cure UC. The main goals of UC treatment include inducing remission rapidly, maintaining the remission stage for a long time and preventing the occurrence of complications. As the incidence of UC keeps rising sharply in the recent 20 years, and a portion of patients have no response to the treatments or the effects are not satisfying, it is necessary to make further research for the treatment of UC. There are some main medical treatments for UC, such as 5-ASA, immune inhibitors, biological agents, Chinese herbal medicine, antibiotics and probiotics. In recent years, some new treatments such as stem cell transplantation, fecal bacteria transplantation and CO enema treatment are becoming the hot spot of research. This article will make a summary of the progress in medical treatment of UC in recent years.

Abstract
Inflammatory bowel disease (IBD), encompassing ulcerative colitis and Crohn's disease, are chronic, relapsing and remitting inflammatory disorders of the intestinal tract. Because the precise pathogenesis of IBD remains unclear, it is important to investigate the pathogenesis of IBD and to evaluate new anti-inflammatory strategies. Recent accumulating evidence has suggested that carbon monoxide (CO) may act as an endogenous defensive gaseous molecule to reduce inflammation and tissue injury in various organ injury models, including intestinal inflammation. Furthermore, exogenous CO administration at low concentrations is protective against intestinal inflammation. These data suggest that CO may be a novel therapeutic molecule in patients with IBD. In this review, we present what is currently known regarding the therapeutic potential of CO in intestinal inflammation.

Abstract
UNLABELLED Abstract Context: Ursodeoxycholic acid (UDCA) exerts dose-dependent chemoprevention in colonic inflammation. Polycationic UDCA nanoparticles (UNPs) are envisaged for solubility enhancement and site directed drug delivery. OBJECTIVE The objective was to study the ameliorative efficacy of UNPs through localized delivery of the drug. METHODS UNPs were prepared through nanoprecipitation technique. Particle size, morphology, in vitro drug release and in vivo protective efficacy in inflammatory bowel disease (IBD) of these nanoparticles were studied. RESULTS AND DISCUSSION The average particle size was around 100 nm, and the average drug encapsulation was about 99%. In vitro drug release study shows optimal drug release in simulated colonic fluid. The lowering of tissue nitric oxide, malondialdehyde, myeloperoxidase and histology of the colon tissue supported the protective efficacy of the nanoparticles. CONCLUSION This study presents the improved efficacy of UNPs in animal model of IBD due to complete release of drug at the desired site of action.

Abstract
The articles contained in this review series exemplify the diverse applications and succinct biological relevance of this simple gas. Articles summarizing the important effects of carbon monoxide in preventing the rejection of an organ, in its neuroprotective properties in piglets, regulation of mycobacterial growth, in its anti-inflammatory effects in the gut and in its use in new and innovative modalities and avenues by which to harness adjuvant therapies are eloquently and precisely described and reviewed. Each of these reports offers but a glimpse of continued prudent and sound evidence that this simple diatomic gas offers astonishingly potent and extremely diverse biological and medicinal qualities.

Abstract
The number of organ and tissue transplants has increased worldwide in recent decades. However, graft rejection, infections due to the use of immunosuppressive drugs and a shortage of graft donors remain major concerns. Carbon monoxide (CO) had long been regarded solely as a poisonous gas. Ultimately, physiological studies unveiled the endogenous production of CO, particularly by the heme oxygenase (HO)-1 enzyme, recognizing CO as a beneficial gas when used at therapeutic doses. The protective properties of CO led researchers to develop uses for it, resulting in devices and molecules that can deliver CO in vitro and in vivo. The resulting interest in clinical investigations was immediate. Studies regarding the CO/HO-1 modulation of immune responses and their effects on various immune disorders gave rise to transplantation research, where CO was shown to be essential in the protection against organ rejection in animal models. This review provides a perspective of how CO modulates the immune system to improve transplantation and suggests its use as a therapy in the field.
