Abstract
With advancements in naval warfare, the number and severity of seawater injuries have skyrocketed, necessitating effective seawater immersion (SWI) wound management. The unique marine pathogens, salinity, low temperature and alkalinity of seawater are the main environmental factors that can influence SWI wound healing. The current treatment strategy for SWI wounds follows a standard protocol based on terrestrial wound conditions, neglecting seawater conditions. The key requirements for ideal SWI treatment include good adhesion to the wound surface to minimize further exposure to seawater, enhanced wound healing properties to minimize wound healing time and antibacterial properties to prevent infections from marine pathogens. Current SWI wound-specific treatments range from elaborate techniques like vacuum-sealed drainage and vacuum-assisted closure for severe blast injuries to simple application of hydrogels or collagen dressings for minor injuries. This review discusses the current status and development of various treatment modalities for SWI wounds. The development of these treatment strategies and an understanding of their mechanisms of action make us better prepared to manage and treat SWI injuries.

Abstract
Disseminated intravascular coagulation, a severe clinical condition caused by an underlying disease, involves a markedly continuous and widespread activation of coagulation in the circulating blood and the formation of numerous microvascular thrombi. A snakebite, including that of the Yamakagashi (Rhabdophis tigrinus), demonstrates this clinical condition. Thus, an animal model using Yamakagashi venom was constructed. Yamakagashi venom was administered to rats, and its lethality and the changes in blood coagulation factors were detected after venom injection. When 300 μg venom was intramuscularly administered to 12-week-old rats, (1) they exhibited hematuria with plasma hemolysis and died within 48 h; (2) Thrombocytopenia in the blood was observed in the rats; (3) irreversible prolongation of prothrombin time in the plasma to the measurement limit occurred; (4) fibrinogen concentration in the plasma irreversibly decreased below the measurement limit; and (5) A transient increase in the plasma concentration of D-dimer was observed. In this model, a fixed amount of Rhabdophis tigrinus venom injection resulted in the clinical symptom similar to the human pathology with snakebite. The use of the rat model is very effective in validating the therapeutic effect of human disseminated intravascular coagulation condition due to snakebite.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 663:245-253. [PMID: 30711591 PMCID: PMC6398278 DOI: 10.1016/j.scitotenv.2019.01.346] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Revised: 01/21/2019] [Accepted: 01/26/2019] [Indexed: 04/14/2023]
Abstract
Epidemiological evidence suggests that fine particulate matter (PM2.5) in air pollution promotes the formation of deep venous thrombosis. However, no evidence is available on the effects of PM2.5 lead to disseminated intravascular coagulation (DIC). For the first time, this study explored the effects of PM2.5 on DIC via coagulation disorders in vivo. SD rats received intratracheal instillation of PM2.5 once every three days for one month. Doppler ultrasound showed that the pulmonary valve (PV) and aortic valve (AV) peak flow were decreased after exposure to PM2.5. Fibrin deposition and bleeding were observed in lung tissue and vascular endothelial injury was found after exposure to PM2.5. Expression of thrombomodulin (TM) in vessel was downregulated after PM2.5-treated, whereas the levels of proinflammatory factors and adhesion molecules (IL-6, IL-1β, CRP, ICAM-1 and VCAM-1) were markedly elevated after exposure to PM2.5. Tissue factor (TF) and the coagulation factor of FXa were increased, while vWF was significantly lowered induced by PM2.5. Thrombin-antithrombin complex (TAT) and fibrinolytic factor (t-PA) were elevated, while there was no significantly change in the expression of anticoagulant factors (TFPI and AT-III). To clarify the relationship between PM2.5 and DIC, we examined the general diagnostic indices of DIC: PM2.5 prolonged PT and increased the expression of D-dimer but decreased platelet count and fibrinogen. In addition, the gene levels of JAK1 and STAT3 showed an upward trend, whereas there was little effect on JAK2 expression. And inflammatory factors (IL-6, IL-1β and TNF) in blood vessels of were up-reglated in PM2.5-treated rats. In summary, our results found that PM2.5 could induce inflammatory response, vascular endothelial injury and prothrombotic state, eventually resulted in DIC. It will provide new evidence for a link between PM2.5 and cardiovascular disease.
