Distal phalanx radiographic grading features in long-toe, underrun heel in Egypt Baladi donkeys (Equus asinus) Ahmed Ibrahim El‐Marakby, Mohamed Barakat Mostafa, Asmaa Abdelsalam Metwally, Ahmed Sayed Soliman, Ahmed Ismael Abdelgalil Equine Veterinary Education, 2025 SummaryBackgroundLong‐toe, underrun heel conformation is a term referring to a long toe, collapsed frog and atrophied heels in equids, including donkeys. However, data on the radiological evaluation and classification of the long‐toe, underrun heel conformation in the donkey are relatively limited.ObjectivesThe present study aimed to determine the relationship between the dorsal hoof wall angle and the radiological angular and linear features of the distal phalanx in long‐toe, underrun heel conformation in Egypt Baladi donkeys.Study designPost‐mortem collected feet.MethodsForty‐seven front hooves with long‐toe, underrun heels from cadavers were radiographically examined. Lateromedial radiometric parameters included dorsal hoof wall angle, heel angle, distal phalanx angle, distal phalanx solar border angle, coronet angle, axis of the distal phalanx angle, proximal palmar cortex angle, distal phalanx to ground distance, distal phalanx to frog distance, distal phalanx to toe distance, foot length and hoof balance%. Long‐toe, underrun heel cadaver feet were classified into four groups according to the dorsal hoof wall angle (DHWA).ResultsThe DHWA of the first group was less than 58.25°–54° (<58.25°:54°), the second group was less than 54°–52° (<54°:52°), the third group was less than 52°–47° (<52°:47°), and the fourth group was less than 47° (<47°). From the first to the fourth groups DHWA, heel angle (HA), distal phalanx solar border angle (P3BA), distal phalanx angle (P3A), axis of the distal phalanx angle (LP3A), proximal palmar cortex angle (PPCA), distal phalanx to frog distance (P3F) and foot length (FL) were decreased, while the coronet angle (CA), distal phalanx to toe distance (P3T) and hoof balance (HB) percentages were increased. Statistical analysis revealed strong and moderate correlations between DHWA and HA, P3A, P3BA, LP3A, PPCA, P3G, P3F and P3T.Main limitationCadaver feet were collected from different yards and body sizes, the collection of radiographic parameters without trimming and the lack of a record of the work history of these donkeys.ConclusionThis study will assist veterinarians in evaluating the long‐toe, underrun heel conformation during hoof trimming.
Development of propolis, hyaluronic acid, and vitamin K nano-emulsion for the treatment of second-degree burns in albino rats Marwan Elsamman, Ola M. El-borady, Mohanad M. Nasr, Zeinab Al-Amgad, Asmaa A. Metwally BMC Complementary Medicine and Therapies, 2024 Burns are the fourth most common type of injury worldwide. Many patients also suffer numerous infections and complications that impair the burn healing process, which makes the treatment of burns a challenge. This study aimed to prepare and characterize nano-emulsion (NE) of propolis, hyaluronic acid, and vitamin K for treatment of second-degree burns. High-Pressure Liquid Chromatography (HPLC) was used for the qualitative assessment of the phenolic and flavonoid contents in crude propolis. The structural, optical, and morphological characterization, besides the antimicrobial, antioxidant, cytotoxicity, in-vitro, and in-vivo wound healing activities were evaluated. For in-vivo study, 30 adult male albino rats were divided randomly into control and treated groups, which were treated with normal saline (0.9%), and NE, respectively. The wounds were examined clinicopathologically on the 3rd, 7th, and 14th days. The NE revealed the formation of a mesh-like structure with a size range of 80–180 nm and a 21.6 ± 6.22 mV zeta potential. The IC50 of NE was 22.29 μg/ml. Also, the NE showed antioxidant and antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The in-vitro investigation of the NE on normal human skin fibroblasts using scratch assay proved an acceleration for wound healing. The treated rats showed improved wound healing clinically and pathologically and wound contraction percent (WC %) was 98.13% at 14th day, also increased epithelization, fibrous tissue formation, collagen deposition, and angiogenesis compared to the control. It could be concluded that the prepared NE possesses antimicrobial, antioxidant, and healing effect in the treatment of second-degree burns.
