Abstract of a scientific article on veterinary sciences, author of the scientific work – Fedota Natalya Viktorovna, Lukyanova Daria Aleksandrovna

The results of testing an ointment based on zinc oxide with the addition of silver microparticles, synthesized by employees of the North Caucasus Federal University, are presented. The ointment is part of a group of new pharmacological preparations for optimizing tissue regeneration processes in thermal burns. The experiments were performed on outbred white rats aged 60-80 days. with an average weight of 130-150 g. It has been established that in terms of the effectiveness of the bactericidal action, silver preparations are in many ways superior to other antibacterial drugs. Final and complete healing of burn wounds in rats with the use of an ointment containing zinc oxide and silver microparticles occurred by 16-18 days. When using Argosulfan and zinc ointments, healing occurred only on the 19-22nd day. i Nadoeli bannery? Vy vsegda mojete otklyuchit advertisement.

The results of testing the ointment based on zinc oxide mixed with silver microparticles, synthesized by the research workers of North-Caucasian Federal University, are submitted in the article. The above ointment is included in the group of pharmacological preparations intended to optimize the processes of tissue regeneration after thermal burns. The non-pedigree white rats aged 60-80 days, with 130-150 g mean weight were included in the experiments. It has been established that the silver preparations in terms of their bactericidal action are much more effective as compared with other anti-bactericidal preparations. The final and complete healing of burn wounds in rats treated with the above ointment, containing zinc and silver microparticles, occurred by the 16-18th day. The healing of wounds treated with Argosulfan ointment occurred only by the 19-22nd days.

Text of the scientific work on the topic “The influence of ointments based on silver and zinc on skin regeneration when modeling thermal burns”

The influence of ointments based on silver and zinc on skin regeneration when simulating thermal burns N.V. Fedota, Ph.D., D.A. Lukyanova, graduate student, Stavropol State Agrarian University An analysis of the Russian pharmaceutical market showed the presence of a fairly wide range of drugs used to treat thermal burns. However, most drugs are not universal, and the effect is far from optimal. This makes it advisable to search and develop perfect and innovative means that stimulate regenerative and reparative processes in tissues [1-3]. The presence of a large number of different sulfonamide drugs and antibiotics in no way reduces the importance of using drugs in the clinic that have natural antibacterial activity. Based on the literature analysis, we considered it appropriate to conduct research on the wound-healing effect of drugs based on zinc oxide and silver microparticles, studying their effect on the regeneration of damaged skin and underlying tissues. In terms of their effectiveness in killing bacteria, silver solutions are much more active than many antibacterial drugs. It is known that silver suppresses both gram-positive and gram-negative microflora, while preserving the natural microflora of the body. An important point is the fact that pathogenic microorganisms do not develop resistance to silver ions. The therapeutic effect of silver on the healing of trophic ulcers that develop due to impaired circulation of the lower extremities has been noted [3-6]. The effect of killing bacteria with silver preparations is very high, which has been confirmed by numerous experiments. Bacteria resistant to penicillin and biomycin are not resistant to silver and its preparations. For the treatment of animals, in particular in the pharmacotherapy of burns, frostbite, bedsores, trophic ulcers, silver preparations such as silver nitrate (lapis), protargol and collargol, Argosulfan, Dermazin are widely used [4-6]. In medicine, one of the components of anti-burn therapy, which has anti-inflammatory, drying, adsorbing, astringent and antiseptic effects, are zinc compounds, which are used externally in the form of powders, ointments, pastes, liniments. Zinc compounds are one of the components of a number of complex dermatological and cosmetic preparations, such as zinc ointment, Lassar paste, etc. Their pharmacological action is in the formation of albuminates and protein denaturation. When applied to the affected surface, the processes of exudation, inflammation and tissue irritation are reduced [3]. The goal of our research is to test new pharmacological drugs to optimize tissue regeneration processes in thermal burns. The subject of research is an ointment based on zinc oxide with the addition of silver microparticles, synthesized by employees of the North Caucasus Federal University. Materials and methods. The experiments were performed on outbred white rats aged 60-80 days. with an average weight of 130-150 g, n = 15. All animals were kept in the same conditions in the vivarium of the Faculty of Veterinary Medicine of the Stavropol State Agrarian University (in natural light, 1 air +20-22°C, humidity 55-60%), in plastic cages measuring 55 x 45 x 15 cm, on a standard food mode, with a bedding of sawdust. Animals were taken into the experiment after seven days of quarantine. The animals were divided into three groups. In I gr. the burn surface in rats was treated twice daily with Argosulfan ointment, in group II. – zinc ointment, III gr. – with the study drug in a similar regimen. Thermal burn modeling was carried out according to generally accepted methods. The area of ​​the burn wound was about 8-9% of the entire body surface. To calculate its values ​​in rats, we used the formula proposed by Mikha: where S is the surface of the body, cm2; W—animal body weight, kg; k is Mich’s constant (9,46). The study included studying the effect of a drug based on zinc and silver on reparative processes after a simulated burn. To do this, we recorded the dynamics of changes in the area of ​​the burn surface, the rate of tissue epithelization, and the nature of the zone of demorcification inflammation. Research results. As a result of the studies, it was found that in animals of group I. on the 5th day. experiment, the average wound area decreased by 27,6%, in group III. – by 48,2%, in II – by 12,1% (table, figure). On the 10th day. experiment, the scab was removed from the burn surface. A clean and pink bottom, located at the level of the edges of healthy skin, was observed only in animals of group III. In rats II gr. the bottom was deep, uneven, the scab was difficult to remove. Average wound area in animals in group III. decreased Area of ​​burn wounds due to the use of various drugs, cm2 Group Experiment period, days. 1st 3rd 5th 10th 14th I 2,53 2,32 1,83 1,1 0,7 II 2,55 2,38 2,24 1,68 1,25 III 2,54 1,82 1,31 0,5 0,2 Argosulfan I Zinc ointment Rice. – Changes in the area of ​​burn wounds due to the use of various drugs by – 80%, I gr. – by 56,5%, II gr. – by 34,1%. In animals II gr. There was a large area of ​​hyperemia around the wound. On the 14th day. experiment, area of ​​burn wounds in rats, group I. decreased by 72,3%, II gr. – by 50,5%, and III – by 92,1%. In animals III gr. area of ​​the burn wound on the 14th day. was less than in groups II and I, by 71,4 and 84,0% respectively. Final and complete healing of burn wounds in rats with the use of an ointment containing zinc oxide and silver microparticles occurred by 16-18 days, in animals of groups I and II. when using Argosulfan and zinc ointment – on days 19-22. accordingly, i.e. for 3-4 days. Later. Conclusions. As a result of the research, it was found that the new ointment based on zinc oxide and silver microparticles has pronounced wound-healing properties compared to well-known monopreparations. 1.
