Abstract Introduction Burn is one of the most severe traumas that causes coagulative destruction of the skin. The use of various products that accelerate wound healing in patients with burn may affect the patient’s survival and reduce the complications that may be seen. In the present study we aimed effects of subcutaneous ozone injection on second degree burn wound. Methods A total of 72 Sprague-Dawley male rats included in the study were divided randomly into three groups (control group (CG), silver sulfadiazine group (SG), ozone group (OG)) and each group was divided randomly two subgroups (as sacrificed on d7 and on d14).A deep second degree scald burns were created on the lower back. In CG subcutaneous 0.9% serum saline was injected daily into the burn area. In SG, burns were dressed with silver sulfadiazine daily and in OG subcutaneous ozone was injected daily into the burn area. Tissue hydroxyproline level measurement and histopathological evaluation were done. Results When the groups were compared in terms of weight change, no significant difference was found on the 7th and 14th days. In the evaluation made in terms of tissue hydroxyproline, tissue hydroxyproline level in OG was found to be significantly higher on both the 7th and 14th days (p < 0.001). In histopathological evaluations, it was determined that wound healing in OG was significantly higher than in the other groups. Conclusions According to the results, subcutaneous ozone therapy is more effective than silver sulphadiazine in the healing process of second-degree burn wounds and it can be safely used in the treatment of burn wounds.

Abstract Burns are one of the most severe traumas, causing coagulative destruction of the skin. The use of various products that accelerate wound healing in patients with burns may affect rates of patient survival and reduce complications. We studied the effects of subcutaneous ozone injection on second-degree burn wounds in animal model. For this study, 72 Sprague-Dawley male rats were divided randomly into the following three groups: control group , silver sulfadiazine group, and ozone group; each group was then divided randomly into two subgroups (day 7 or day 14 examination and sacrifice). Superficial partial thickness burns were created on the lower back. In the control group, subcutaneous 0.9% serum saline was injected daily into the burn area. In the silver sulfadiazine group, burns were dressed daily with silver sulfadiazine. In the ozone group, subcutaneous ozone was injected daily into the burn area. We performed tissue hydroxyproline level measurements and histopathological evaluations. When groups were compared in terms of weight change, no significant difference was found between day 7 and day 14. With regard to tissue hydroxyproline levels the ozone group had significantly higher levels on both day 7 and day 14 (P < .001). In histopathological evaluations, we determined that wound healing in the ozone group was significantly higher than in the other groups. We found that subcutaneous ozone therapy was more effective than silver sulfadiazine in the healing process of second-degree burn wounds and could be safely used in the treatment of burn wounds.

Abstract Background: Burn injury is common, burn ointment (BO) is a common preparation used to treat burns and scalds in folk as an effective remedy for burn healing. The present study was undertaken to evaluate the healing effect and related underlying mechanisms of BO in a model of deep second-degree thermal burn by animal experiments. Methods: BO is was made up of a combination of extracts from several traditional Chinese medicine and borneol, solid paraffin, rapeseed oil, and and its quality control was assessed. The acute toxicity test and skin irritation test were evaluated by rats. The anti-inflammatory effect was revealed by using inflammation animal models, including the xylene-induced auricle swelling in mice and carrageenan-induced toe swelling in rats. The hot plate test was used to evaluate its analgesic activity. Moreover, the experiments of knife and a deep second-degree burn wound were used to explore the effect of BO in promoting wound healing. On days 7, 14 and 28, the wounds were digitally photographed by a camera and after sacrifice of the SD rats, skin samples were obtained for performing H&E staining, immunohistochemical staining and Western Blotting examination. In addition, The expressed of TNF-α, TGF-β1 and VEGF in serum were detected by ELISA kits. Results: BO had no toxicity or side effects on the skin and liver or kidney function. BO could significantly inhibit auricular swelling in mice, paw welling in rats and markedly prolonged the latencies of licking paws in mice; it also could accelerate the process of wound healing and repair scar by promoting the formation of new epithelial tissue. In addition, BO significantly reduced the content of TNF-α and markedly increased the content of VEGF and TGF-β1 in the serum. Moreover, BO promoted the expression of collagen I. Furthermore, it increased the ratio of p-PI3K/PI3K, p-AKT/AKT and p-mTOR/mTOR in the PI3K / AKT / mTOR pathway.Conclusions: BO could effectively reduce inflammation and pain, and effectively accelerate the healing process of deep second-degree burn wounds. And the mechanism of BO promoting wound healing may be related to activate PI3K / AKT / mTOR pathway. therefore, it may be recommended as a promising topical medication for treating burn wounds in the future clinical trials.

Many researches have been exerted to find an application dressing for wound healing and also attain a considerable microbial reduction in burn wounds. In this study, the healing effect of a mixed herbal ointment (containing Myrtus, honey, Aloe vera, and pseudomonas phage) on the healing process of second degree burn wounds infected with Pseudomonas aeruginosa in comparison was evaluated. For this purpose, a hot metal square piece (4×2 cm, 50 g) was applied using a standard burning technique, and the applied pressure on the skin kept the same for all animals, then infected with Pseudomonas aeruginosa. Rats were randomly divided into 2 groups. Group 1 was treated with mixed herbal ointment, and group 2 received no treatment (control group). The treatment was daily, and sampling was weekly for three consecutive weeks (7, 14, and 21-day). Formalin 10% was used for tissue fixation. Wound healing in test and control groups was investigated by macroscopic and microscopic methods using Hematoxylin-Eosin staining. It wound contraction evaluation (Image J software). Macroscopic findings showed that wound contraction of the mixed herbal ointment group was significantly higher than the control group for 21 days. Hematoxylin-Eosin staining revealed that the epithelialization was considerably more completed in the mixed herbal ointment group in comparison with the control group. Also, neovascularization was significantly higher in the mixed herbal ointment group. The comparative results demonstrated that the mixed herbal ointment group had a significant difference (P<0.05) with a non-treated group (control). Therefore, the mixed herbal ointment is suggested as a suitable candidate for the treatment of second-degree burn wounds infected to pseudomonas aeruginosa.

Background: Wound healing requires processes like cell migration, proliferation of extracellular matrix deposition, remodeling and angiogenesis. Also, anti-oxidative and anti-inflammatory reactions play key roles in the progression of wound healing. Previous studies showed that sesame oil has anti-inflammatory, antimicrobial and antioxidant activities. In addition, it is shown that sesame oil stimulates fibroblast production in vitro and in skin wounds. Therefore, in this study we investigated the effects of sesame ointment on the process of second-degree burn wound healing in rat models according to stereological parameters. Materials and Methods: In this experimental study, forty male Wistar rats (200±20 g) were randomly divided into four groups (n=10): ointment-base treated group (vehicle), silver sulfadiazine (SDD) treated group, sesame treated group (E1) and the control group which received no treatment. A 2×3 cm2 standard second-degree burn wound was induced on the posterior surface of animal’s neck under general anesthesia. After sacrifice, the animal’s skin sample was fixed in buffered formaldehyde for stereological evaluations. The data was analyzed by SPSS statistical software (version 14.0). P<0.05 was considered statistically significant. Results: According to our results, the mean of reduction in wound areas, volume density of collagen bundles and hair folicules, fibroblast populations, length density of vessels in E1 group was significantly higher than control group (P<0.05). The differences between E1 and SSD were not statistically noticeable regarding the stereological parameters. Conclusion: According to stereological analysis, administration of sesame ointment showed the ability to improve wound healing process and tissue regeneration in the treatment of skin damages.[GMJ.2016;5(2):56-62]

Abstract Hyperbaric oxygenation therapy has found its application in the treatment of various types of burns. The presented work describes the use of this method in treating napalm burns in experimental animals. The researchers took particular interest in the immunological reactions occurring in animals, as well as the effect of the said therapy on the healing process. Two groups of rabbits, previously anaesthetised with Evipan and immunised with S. typhi phage F7 microorganisms, were burnt with the use of napalm. The tested group was subjected to a series of treatment sessions with 100% oxygen at the pressure of 2 atm, whereas the control group did not undergo such treatment. Six repeated tests on complement activity with 50% haemolysis method and heamagglutination reaction quantification with antigens O and H S.typhi phage F7 were carried out on all of the researched animals. Moreover, for the purpose of control of the healing process, a number of histopathological exams on the burn wounds were conducted in both groups of rabbits. The research showed an increase in complement activity in all tested animals; however, in the tested group it occurred later. Histopathological tests confirmed a more advanced healing process in the group subjected to hyperbaric oxygenation.

AbstractThe purpose of this study was to evaluate whether cryopreserved (frozen) adipose-derived regenerative cells (ADRCs) have a therapeutic effect on burn wound healing as well as freshly isolated (fresh) ADRCs.Full thickness burns were created on dorsum of nude mice and burn wound was excised. The wound was covered by artificial dermis with; (i) fresh ADRCs, (ii) frozen ADRCs, and (iii) PBS (control). The assessment for wound healing was performed by morphological, histopathological and immunohistochemical analyses.In vivo analyses exhibited the significant therapeutic effect of frozen ADRCs on burn wound healing up to the similar or higher level of fresh ADRCs. There were significant differences of wound closure, epithelized tissue thickness, and neovascularization between the treatment groups and control group. Although there was no significant difference of therapeutic efficacy between fresh ADRC group and frozen ADRC group, frozen ADRCs improved burn wound healing process in dermal regeneration with increased great type I collagen synthesis compared with fresh ADRCs.These findings indicate that frozen ADRCs allow us to apply not only quickly but also for multiple times, and the cryopreserved ADRCs could therefore be useful for the treatment of burn wounds in clinical settings.
