A cup plant (Silphium perfoliatum L.) is a poorly-known crop in the country. It came to Europe from North America in the 18th century. It can be propagated by dividing rhizomes or by sowing seeds. This plant is undemanding in terms of alimentary requirements and resistant to cold and pests. Due to the high content of nutrients and the yield of green mass a cup plant is used for fodder purposes. A cup plant contains numerous secondary metabolites, such as phenolic acids, flavonoids, terpenes, essential oil, tannins, vitamins and mineral components. It is characterized by antioxidant, antibacterial, antifungal, cytostatic and immunosuppressive activity. Research on laboratory animals indicates that the cup plant accelerates wound healing and indicate hypolipemic and estrogenic activity. Numerous reports confirm, that this plant also has a strengthening, diuretic, anti-inflammatory, antihemorrhagic and spasmolytic activity. In addition, it is used in the healing diseases of the liver and spleen, and also heals gastric and duodenal ulcers.

Thermal burns in animals represent an urgent problem for veterinary medicine, since the anti-burn drugs available on the world pharmacological market are not always adapted for use on animals and are approved for use in veterinary medicine. In this regard, the aim of the work was to use the wound healing spray “Acerbin” for medical purposes in the treatment of thermal burns and to evaluate its therapeutic efficacy by the rate of epithelialization of burn defects in the skin in laboratory animals. The work was carried out at the Department of Surgery and Therapy of the Kursk State Agricultural Academy, on laboratory white mice in the amount of 60 individuals, in which thermal burns were simulated in the croup and treated with applications of the Acerbin spray. To assess the rate of growth of epithelialization, planimetric measurements of the area of burns were carried out before treatment on the 3rd, 5th, 7th, 10th and 14th days of treatment, as well as the corresponding mathematical calculations of the rate of reduction of burn defects. According to the research results, it was found that when applying the Acerbin spray, the burn rate index on the 3rd day was 0.25 ± 0.06; on the 5th day 0.58 ± 0.03; on the 7th day 0.74 ± 0.01; on the 10th day 0.86 ± 0.02; on the 14th day 0.95 ± 0.01. Thus, at the end of the therapeutic period, the index of the epithelialization rate of thermal burns approached the most physiologically justified numerical expression equal to “1.0”, which allows it to be recommended for use in veterinary medicine as the preparation of choice for the treatment of thermal burns of the skin in animals.

AbstractNon-healing wounds are associated with high morbidity and might greatly impact a patient’s well-being and economic status. For many years, scientific research has focused on developing and testing several natural and synthetic materials that enhance the rate of wound healing or eliminate healing complications. Honey has been used for thousands of years as a traditional remedy for many ailments. Recently, honey has reemerged as a promising wound care product especially for infected wounds and for wounds in diabetic patients. In addition to its proposed potent broad-spectrum antibacterial properties, honey has been claimed to promote wound healing by reducing wound hyperaemia, oedema, and exudate, and by stimulating angiogenesis, granulation tissue formation and epithelialisation. Several animal models, including large animals, dogs and cats, and different species of laboratory animals have been used to investigate the efficacy and safety of various natural and synthetic agents for wound healing enhancement. Interpreting the results obtained by these studies is, however, rather difficult and usually hampered by many limiting factors including great variation in types and origins of honey, the type of animal species used as models, the type of wounds, the number of animals, the number and type of controls, and variation in treatment protocols. In this article, we provide a comprehensive review of the most recent findings and applications of published experimental and clinical trials using honey as an agent for wound healing enhancement in different animal models.

Abstract Background Alnus glutinosa (L) is a widespread medicinal plant on the territory of the Republic of Belarus. Alnus glutinosa (L) leaves tincture has an anti-inflammatory effect on the diseases of the throat, intestines, in rheumatism and gout. Water extracts from collective fruit, leaves and bark are used for gargling in stomatitis and gum bleeding. The purpose of the research was to establish wound healing activity of gels based on alcohol extracts from Alnus glutinosa (L) leaves on the model of a surface full flap skin wound on laboratory animals. Methods Regenerating action of new drugs (gels) based on tinctures of Alnus glutinosa (L) leaves was studied on a model of planar full-layer skin wound in laboratory animals. Wounds were treated daily with gels applied to complete healing. The wound area was measured planometrically to assess the effectiveness of drugs and then the percentage of area reduction was calculated. Regenerative action of the gels developed was compared to widely used in medical practice 4% Dexpanthenol Gel and Reparef-2 Ointment. 15 g of Reparef-2 Ointment contains 1200 mg of bien and 75 mg of dioxidine. Results Wound healing activity of gels containing tinctures of Alnus glutinosa (L) leaves based on 30% and 60% alcohol as to the rate of healing and the area of wounds epithelialization has been proved. Wound area treated with the gel based on Alnus glutinosa (L) extract containing 60% alcohol on day 13 of the experiment decreased by 95.59% ± 0.9% (p ≤ 0.05); based on the tincture containing 30% alcohol - by 92.93% ± 1.11%. Medicinal preparations with proved wound healing activity were compared: Reparef-2 Ointment (reduction percentage of wound area on day 13 of the experiment made 92.24% ± 2.21%) and Dexpanthenol Gel (reduction percentage of wound area on day 13 of the experiment made 83.09% ± 3.41%). Compared with the control group the gel based on 60% tincture of Alnus glutinosa (L) leaves showed a decrease in the epithelialization period by 29.5%; based on 30% tincture - by 24.6%; Reparef-2 Ointment - by 23.6% and Dexpanthenol Gel - by 13.8%. Conclusions The results of this study showed that the developed gels based on Alnus glutinosa (L) have a regenerating action and can be used to treat wound processes taking into account previously established antimicrobial activity.

Introduction: Thermal burns account for 5-10% of casualties sustained in present-day conflicts and are expected to be one of the most common wounds to occur in future conflicts. Timely debridement of necrotic burn tissue can greatly reduce the chances of mortality and late-stage complications. However, future conflicts are anticipated to occur in austere environments where surgical debridement may not be plausible and casualty evacuations significantly delayed. Without access to prompt surgical interventions and standard treatment, burn wounds can progress (become deeper and more extensive) and become highly susceptible to infection. Several studies have demonstrated that topical applications of Cerium (III) Nitrate (Cen) can be used to delay the need for surgical eschar removal, a delay which may be forced upon injured warfighters in austere environments. The proof-of-concept studies described herein suggest that an electrospun dressing with a Polyethylene Oxide (PEO) shell and CeN core could prolong the time before surgical intervention is required and/or mitigate late-stage burn pathophysiologies in Prolonged Field Care (PFC) scenarios. Materials and Methods: Coaxially electrospun PEO dressings with a CeN payload were synthesized for application in a swine burn model. Dressings were first evaluated ex vivo using a Lactate Dehydrogenase (LDH) assay to confirm that no cytotoxic effects were present. Then, one female Yorkshire pig was anesthetized and received ten 5 cm x 5 cm contact burns with a brass burn device that was heated to 100°C. The deep-partial thickness wounds were randomly assigned to one of five treatment groups: 1) 1-Layer of the PEO/CeN dressing, 2) 4-Layers of the PEO/CeN dressing, 3) 4-layers of a control electrospun PEO dressing, 4) Flammacerium® cream (silver sulfadiazine 1%, cerium nitrate 2.2%), or 5) the PFC standard of care (SOC; gauze). Wounds were observed over an 18-day period, with surgical debridement occurring on Day 4 for all wounds. Transepidermal water loss, depth to debridement, and histologic measurements of necrosis were utilized to assess the burns. Research was conducted in compliance with the Animal Welfare Act, the implementing Animal Welfare regulations, and the principles of the Guide for the Care and Use of Laboratory Animals, National Research Council. The facility’s Institutional Animal Care and Use Committee approved all research conducted in this study. The facility where this research was conducted is fully accredited by AAALAC International. Experimental design and statistical comparisons were approved by an accredited epidemiologist and biostatistician. Results: The PEO/CeN dressings did not elicit a cytotoxic response ex vivo. Compared to the PFC SOC, treatments containing CeN reduced the amount of necrotic tissue produced by second-degree thermal injuries, as evidenced both histologically and in the depth required to reach viable tissue during surgical debridement. Importantly, the dressing did not adversely impact the live tissue surrounding the burn site. Conclusions: There are currently no field dressings that can delay the need for immediate debridement and thereby promote burn wound healing. This proof-of-concept study strongly suggests that the electrospun PEO/CeN dressing could fulfill this unmet medical need and advocates for further evaluation for use in imminent PFC scenarios.
