  • Burns can be caused by fire, chemicals, heated object and fluids. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. Algin is known as natural polymer marine plants, we prepared the official burn ointment which is made by Algin. This burn ointment was covered on the skin wound of artificial burned and their effect of healing was investigated by the evaluation of histological and hematological change as a function of time. The result of rats test showed that burn ointments made from Algin was effective in formation of the new tissue and reduction of inflammation.

  • This study was conducted in order to examine the effect of burn damage and the resultant anti-corrosion performance. The breakdown and defect of the paint film caused by burn damage are considered to affect not only the macroscopic appearance but also the adhesive force and the anti-corrosion performance of the paint film. The material of the paint film was epoxy paint that is used most widely for heavy-duty coating, and in order to induce burn damage, heat treatment with a torch was applied to the other side of the paint film. Surface and chemical structure changes according to aging were analyzed using FE-SEM and infrared absorption spectroscopy, and variation in the anti-corrosion performance was analyzed through the AC impedance test.

  • Biodegradable films were prepared by solution blend method in the weight ratio of chitosan for the purpose of useful biomaterials. The possibility of biomaterials prepared from natural polymer as a skin substitute was evaluated by measuring biocompatibility. These films were inserts in the back of rat and their biodegradability was investigated by the film weight and hematology as a function of time for the biotransformation. The result of rat test showed that medium, high viscosity chitosan induced some suspects of inbiocompatibility in the tissue by goreign body reaction 48 and 72 hours after implantation. Also, we prepared the official burn ointment which is made by low viscosity chitosan. This burn ointment was covered on the skin wound of artificial burn and their effect of healing was investigated by the evaluation of the naked eye and hematological change as a function of time. The result of rats test showed that burn ointments made from chitosan was effective reductio of inflammation than negative group.

  • Purpose: The purpose of this study was to examine the burn characteristics of female patients hospitalized in a burn center. Methods: This is a retrospective descriptive study. The subjects were 222 female patients aged over 19 years old having burn injuries from work sites between January 1, 2012 and December 31, 2014. Data were collected using electronic medical records about the burn-related characteristics. The data were analyzed descriptively. Results: Many of the subjects were in their forties and fifties. Most subjects showed burns with an area of less than 10% of the body surface with a severity of second degree. Scalding burns were the most frequent. Contact burns were usually of third-degree severity and occurred on hands and wrists. Flame burns affected the largest body surface area and frequently occurred on the face and mainly caused by explosion of a stove or kitchen gas. Chemical burns frequently occurred on the lower limbs. Conclusion: Female workers are exposed to the hazards of burn injuries in industrial accidents. Types of burn differ depending on the workplace conditions. Therefore, preventative measures for burn injuries should be established in accordance with the characteristics of each industry to which female workers belong.

  • Infection is one of the main causes of death in severe burn cases. Treatment of burn patient includes fluid therapy, wound care, complication care and antibiotic therapy for infection. The objective of this study was to evaluate the characteristics of burn patients, the type of isolated microorganisms and their susceptibility, and the systemic antibiotics used. This is a retrospective study of 126 burn patients treated in the Hanil General Hospital from January to December 2001. Total 126 patients were assessed with 103 males and 23 females (4.5:1). The average age was $34.8\pm17.6$ years and extent of burn $(TBSA\;\%)\;was\;24.5\pm18.5\%$. The burn was caused by electric accident $(47.6\%),\;flame\;(29.4\%),\;scalding\;(21.4\%),\;and\;chemical\;accident\;(1.6\%)$. The overall mortality rate was $7.14\%$ (9/126) and all expired patients were males. The average age (n=9) was $48.8\pm15.6$ yrs and the extent of burn was $65.0\pm19.0\%$. The causes of death were due to flame burns $(13.5\%)$ and electric burns $(6.7\%)$. The culture sites of the isolated microorganisms were wound $(85.3\%),\;sputum\;(9.3\%),\;urine\;(2.7\%),\;blood\;(1.3\%)\;and\;catheter\;tip\;(1.3\%)$. Pseudomonas aeruginosa was the most commonly isolated organism $(35\%)$, followed by Staphylococcus aureus $(30.1\%)$, Acinetobacter baumannii $(21.4\%)$, and Enterococcus spp. $(3.9\%)$. The number of systemic antibiotics administered was 4.5. The classes of the antibiotics were cephalosporines $(38.5\%)$, aminoglycosides $(31\%)$, quinolones $(13.3\%)$, penicillins $(12.4\%)$, carbapenems $(2.4\%)$, glycopeptides $(1.9\%)$ and others $(0.6\%)$. In conclusion, most of burn patients had wound infection and Pseudomonas aeruginosa was the most commonly isolated organism. Cephalosporins were administered the most frequently among antibiotics.

  • A 22-year-old woman was referred to our emergency department for the treatment of a chemical injury on her arm. She had accidentally spilled 99% trifluoroacetic anhydride (TFAA) over her left forearm during an organic chemistry experiment. She visited a primary care unit, and then she was referred to our hospital for inactivation of the released fluoride ions. Her skin lesions were different from those caused by hydrofluoric acid (HF) injury. The injured area showed painful whitish maculae and patchy areas with accentuated rim. No vesiculation and bulla formation was detected. We intradermally injected a 5% solution of calcium through a 24-gauge needle into the burned skin. After the injection, she complained of more severe pain. Although TFAA contains fluorine, it does not release free fluoride ions on contact with the skin, unlike HF. In fact, application of calcium gluconate for TFAA burns is not recommended. Rather, it should be avoided since it increases pain and local abscess formation.

  • This study conducted a research on burn-out printing convergence technology for cellulose blend knit fabrics. Printing technology, which forms color pattern on the fabric, can be generally classified into four according to printer or printing method, e.g. screen printing, roller printing, rotary printing, digital printing. However, these printing methods are flat in design or pattern, which have limitation to overcome monotonousness of fabric, so that recently burn-out process method, which expresses three-dimensional pattern effect by treating chemical on the surface of fabric as the method to appeal its esthetics to the customers. Particularly, in case of cellulose/polyester composite material, first, it is proceeded in 2 processes, by dyeing cellulose or polyester fabric and burning out cellulose fabric, in this process, due to pollution caused by disperse dye migration, color of polyester fabric part could be discolored, which has high falt risk. This research considered coloring burn-out technique, which simultaneously proceed dyeing and burn-out by reducing dyeing and burn-out process to 1 stage, which were proceeded in 2 stages previously. As the research result, it was confirmed that reasonable depth of roller was 0.04~0.06mm in roller printing process, heat treatment condition of burn-out far-infrared radiation was $185^{\circ}C{\times}30m/min$. Color fastness to washing was confirmed to be 4-5 grade, color fastness to rubbing, 3-4 grade, color fastness to light, 4 grade. Also, it was confirmed that energy reduction effect appeared 38.19%, in case of energy cost per yard compared to the existing production, also, 19.74%, in case of production cost.

  • Background and Objectives Ocular alkali burns cause severe damage to the ocular tissues and vision loss. Solcoseryl is a standardized calf blood extract that normalizes the metabolic disturbance and aids in maintaining the chemical and hormonal balance and has been used to treat burns in various tissues. This study examined the effects of Solcoseryl on a rat corneal alkali burn model. Materials and Methods Twenty rats were assigned randomly to four equal groups, including alkali burn, hyaluronic acid, Solcoseryl eyedrop, and Solcoseryl gel. A corneal alkali burn was induced by a NaOH-soaked paper disc. The treatments were given twice a day, every day. The wound area was measured after 24 and 48 hours, and the degree of neovascularization and corneal opacity were scored every week. The rats were sacrificed after three weeks for immunohistochemistry (IHC) to compare the level of inflammatory cytokines, IL-1β, IL-6, and TNF-α. The thickness of the retinal layers was compared to observe any changes in the retina. Results The use of Solcoseryl on corneal alkali burn accelerated wound healing with less neovascularization, greater opacity, and less cataract. IHC showed that the inflammation of the cornea was controlled by both the hyaluronic acid and Solcoseryl treatments. On the other hand, the inflammation had spread to the retina. When the dosage forms were compared, eyedrops were more effective on corneal inflammation, while the gel-type had a greater effect on retinal inflammation. Conclusion Solcoseryl was effective in accelerating the wound healing rate on a corneal alkali burn but could not prevent the spread of inflammation from the cornea to the retina. Eyedrops were more effective on inflammation in the cornea, and the gel was more effective in the retina.

  • The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.
