    Acellular dermal matrices (ADMs) are gaining popularity as surgical materials for operations on the pelvic organs, as well as in burn therapy and plastic surgery. Evaluation of the biocompatibility of surgical materials is an important and necessary step in the development of new ADMs.The aim of the study was to compare the results of subcutaneous implantation of ADM and native porcine skin in rats.Materials and methods. To obtain ADMs, detergent – enzymatic decellularization was used. On days 7, 14, 21, and 60 after the implantation of ADMs (the experimental group) and native porcine skin (the control group), the animals were removed from the experiment. The histologic sections were stained with hematoxylin – eosin and Masson’s trichrome stain, then an immunohistochemical reaction with antibodies to CD3 and CD68 was performed. Computer morphometry was carried out using the ImageJ software.Results. On day 7 after the implantation, moderate sterile inflammation in the experimental group and pronounced sterile inflammation with eosinophil infiltration in the control group were observed. On day 14 of the experiment, the samples from the experimental group were characterized by a relatively low content of macrophages and T-lymphocytes with insignificant edema and no signs of ADM biodegradation. The control group showed pronounced inflammation, a large number of infiltrating macrophages and T lymphocytes, as well as fragmentation of collagen fibers. On day 21 of the experiment, a thin capsule was formed around ADM, there was a small number of infiltrating T lymphocytes and macrophages, the collagen fibers of the implant were intact. In the samples of the control group, there was pronounced inflammation with the presence of a significant number of lymphocytes and macrophages, as well as fragmentation and vascularization of the implant. On day 60 of the experiment, no inflammatory response was observed around ADM, biodegradation was minimal, and a dense fibrous capsule was formed around the fragment of the native porcine skin.Conclusion. The experimental ADM has low immunogenicity and a low degree of biodegradation, which makes it possible to use it for further research to create efficient surgical material that is safe for use in clinical practice.ΠΡ†Π΅Π»Π»ΡŽΠ»ΡΡ€Π½Ρ‹Π΅ Π΄Π΅Ρ€ΠΌΠ°Π»ΡŒΠ½Ρ‹Π΅ матриксы (ΠΠ”Πœ) Π½Π°Π±ΠΈΡ€Π°ΡŽΡ‚ Π±ΠΎΠ»ΡŒΡˆΡƒΡŽ ΠΏΠΎΠΏΡƒΠ»ΡΡ€Π½ΠΎΡΡ‚ΡŒ Π² качСствС хирургичСских ΠΌΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»ΠΎΠ² ΠΏΡ€ΠΈ опСрациях Π½Π° ΠΎΡ€Π³Π°Π½Π°Ρ… ΠΌΠ°Π»ΠΎΠ³ΠΎ Ρ‚Π°Π·Π°, Π² ΠΎΠΆΠΎΠ³ΠΎΠ²ΠΎΠΉ Ρ‚Π΅Ρ€Π°ΠΏΠΈΠΈ ΠΈ пластичСской Ρ…ΠΈΡ€ΡƒΡ€Π³ΠΈΠΈ.

    Goal of the research: to determine the efficacy of a new line of Atopic cosmetic products for skin care in children suffering from atopic dermatitis. Materials and methods: The study involved three groups of 15 children aged 3-12 suffering from atopic dermatitis in each group. Subjects from Group 1 were treated with Atopic Soothing Cream, from Group 2 with Atopic Soothing Stick Cream and from Group 3 with Atopic Everyday Care Cream. Different inclusion and exclusion criteria were developed for each group, and the algorithm for the product application and efficacy criteria were determined. According to recommendations, Atopic Soothing Cream and Atopic Soothing Stick Cream were applied to clean and dry skin in the morning and in the evening for the study period of 14 days. The patients’ skin condition was assessed prior to the study and on Day 14 of the therapy; the assessment covered parameters necessary for calculating the SCORAD Index. Atopic Everyday Care Cream was applied to clean and dry skin in the morning and in the evening for 28 days. The patients’ skin condition was assessed prior to the study and on Days 14 and 28 of the therapy including the SCORAD Index and assessments of the skin hydration level of the epidermal corneous layer and transepidermal waster loss (TEWL) using the DermaLabCombo CORTEX device. According to the study results, the line of Atopic cosmetic products fully complies with the properties specified by the manufacturer, reliably improves the skin condition in children suffering from atopic dermatitis, has no irritant or sensitizing effect, and can be recommended for the complex treatment and rehabilitation of patients suffering from the pathology

    Aim. To study the efficacy of dermal hydrogel application in the experimental treatment of superficial scarified wounds in rats.Materials and methods. The hydrogel was obtained from porcine dermis by alkaline hydrolysis. The DNA concentration was determined using the Nano Drop ND-1000 spectrophotometer. The study included 30 male Sphinx rats. Scarified wounds were created on the rat skin, then the rats were divided into two groups: group 1 – rats without treatment, or control group (n = 15), group 2 – rats with wound treatment with the dermal hydrogel for 5 days, or experimental group (n = 15). On day 3, 7, and 14 of the experiment, we explanted skin samples from the wound area and performed routine H&E staining.Results. On day 3 of the experiment, moderate inflammation, edema, and collagen fiber disorganization were revealed in the experimental group, and pronounced inflammation with purulent exudate was found in the control group. On day 7 of the experiment, inflammation and foci of stratified epithelium were detected in the control group. The histologic analysis of the skin samples from the experimental group showed pronounced plethora of the vessels, necrotic changes of the dermis, and edema. The total thickness of the epidermis and the thickness of its stratum corneum were greater than in the control group samples. On day 14, the differences between the groups were minimal and the epidermis was thickened in the experimental group animals.Conclusion. The study examined the effects of the dermal hydrogel on scarified wounds in rats. We found faster skin regeneration (by 1.5–2 days) in the experimental group compared to the controls. Besides, the rats of the experimental group were characterized by an increase in the number of fibroblasts in the dermis and thickened epidermis in the affected area.ЦСль – ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ эффСктивности использования Π΄Π΅Ρ€ΠΌΠ°Π»ΡŒΠ½ΠΎΠ³ΠΎ гидрогСля ΠΏΡ€ΠΈ ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½ΠΎΠΌ Π»Π΅Ρ‡Π΅Π½ΠΈΠΈ повСрхностных скарифицированных Ρ€Π°Π½ Ρƒ крыс.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
