Open Veterinary Journal May 2024A fracture is considered a medical emergency leading to considerable complications.
BACKGROUND
A fracture is considered a medical emergency leading to considerable complications.
AIM
This study aimed to describe the accelerating action of Ag-NPs-FG on fracture healing in rabbits.
METHODS
Silver NPs (AgNPs) were reduced with fenugreek (FG), loaded into a starch gel base, and investigated for their morphology, size, and charge. Four equal groups were randomly formed of 40 adult male rabbits. A 3.5 mm diameter bone defect was created at the proximal metaphysis of the right tibia in each rabbit. Groups 1-4 were injected with placebo saline, AgNPs-FG, plain gel, and FG-gel at the bone defect zone, respectively. The healing was assessed for 8 weeks postoperatively based on the radiographic, bone turnover markers, and histopathological examinations.
RESULTS
The AgNPs-FG was obtained as a faint reddish color, spherical in shape, with an absorbance of 423 nm, a size of 118.0 ± 1.7 nm, and a surface charge of -7.8 ± 0.518 mV. The prepared AgNPs-FG hydrogel was clear, translucent, and homogenous. The pH values were 6.55-6.5 ± 0.2, the viscosity of 4,000 and 1,875 cPs, and spreadability of 1.6 ± 0.14 and 2.0 ± 0.15 for both FG and AgNPs-FG hydrogel, respectively. The radiographic union scale was significantly ( < 0.05) improved in group 2 with a significant ( < 0.05) increase in bone turnover markers was found in comparison to other treated groups. Histopathological examination revealed the formation of mature bone on the 28th postoperative day in groups 2 and 4.
CONCLUSION
Colloidal nano-formulation of AgNPs-FG loaded hydrogel could be a promising formulation to accelerate rabbits' tibial bone healing process.

BACKGROUND
Fractures with large bone defects and non-unions are a great challenge for veterinary orthopaedists. In small dog breeds, this complication is commonly encountered in fractures of the radius and ulna due to poorer vascularisation of the distal antebrachium region.
CASE DESCRIPTION
A case of radius/ulnar non-union in a 1.5-year-old Pinscher occurring after trauma and two successive unsuccessful osteosyntheses is described. During the operative revision, after the removal of existing bone implants, the bone defect was filled with cortical autologous bone graft. Autocancellous bone mixed with erythropoietin was applied proximally and distally to the cortical autograft for stimulation of bone healing. The post-operative period was without complications. As early as the 9th post-operative week, the animal was able to bear weight on the limb, without signs of lameness, pain, and swelling. Radiologically, a very good bridging of the graft was observed. Fifteen weeks after the operative revision, the fracture was completely healed with excellent clinical outcome.
CONCLUSION
The application of autogenous cortical bone graft and cancellous autograft mixed with erythropoietin demonstrated an excellent therapeutic effect and resulted in complete regeneration of the large bone defect over a 15-week period.

BACKGROUND
Acute hemorrhage is fatal in equines with a complication of severe hypovolemic shock that causes a sudden death in such cases.
AIM
This study was designed to report the influences of acute bleeding in conscious non-sedated donkeys () on the hematobiochemical variables, acid-base, blood gas elements, and markers of inflammation and bone metabolism.
METHODS
Eight healthy donkeys were used where a total of 900 ml of whole blood was collected. Five blood samples were collected from each animal: just before collection of blood (T0); (2) 30 (T1), 60 (T2), 120 (T3), and 240 minutes (T4) later. The blood panels including total white blood cells, lymphocytes, neutrophils, red blood cell counts (RBCs), HCT, hemoglobin (Hg), and RBCs indices were measured. Biochemical parameters and electrolytes were evaluated. The activity of aspartate aminotransferase (AST), creatine kinase (CK), and γ-glutamyl transferase (GGT) were also determined. Complete acid-base and blood gas panels were assessed. Serum amyloid A (SAA), haptoglobin (Hp), osteocalcin (OC), bone alkaline phosphatase (b-ALP), and pyridinoline cross-links (PYD) were measured.
RESULTS
The RBCs, Hg, and HCT increased significantly at points T1, T2, and T3 compared to T0. The concentrations of total proteins and albumin decreased significantly at points T3 and T4. The blood urea nitrogen concentrations increased significantly at T4. Creatinine concentrations increased significantly at T2 and T3. The AST, GGT, and CK decreased significantly. On the other hand, glucose increased significantly at T3 and T4. The pH decreased significantly at points T1, T2, T3, and T4. The PCO increased significantly at T3 and T4. The BE, HCO, and TCO values decreased significantly at T2, T3, and T4. Contrary, the AG increased significantly at points T3 and T4. The potassium increased significantly at T1-T4 and chloride decreased significantly at T3 and T4. Lactate showed significant increases at T1-T4. The SAA, Hp, OC, b-ALP, and PYD did not differ significantly at T1-T4.
CONCLUSION
In conscious non-sedated donkeys, induced bleeding resulted in significant changes in the hematobiochemical elements, the acid-base status, and blood gas and electrolyte parameters. However, it did not change the markers of inflammation and bone metabolism.

BACKGROUND
This research describes the methodology used for the preparation of selenium nanoparticles from and their administration to lambs for lipid profile checking, administration of selenium nanoparticles as a medication in lambs results in hypolipidemia.
AIMED
The study aimed to investigate the potential of selenium nanoparticles in improving lipid profiles in lambs.
METHODS
Healthy lambs ( = 10) of similar age and weight were selected for the study. The animals were housed in individual pens with free access to water and a standard diet. The lambs were randomly divided into two groups: the control group ( = 5) and the treatment group ( = 5). The control group received a standard diet, while the treatment group received the same diet and oral administrated with selenium nanoparticles at 0.1 mg/kg body weight. The administration was carried out daily for a period of 8 weeks. Blood samples were collected from the jugular vein of each lamb at the beginning of the study (baseline) and at the end of the 2 weeks treatment period. The samples were collected in vacutainer tubes and allowed to clot. Serum was separated by centrifugation at 3,000 rpm for 10 minutes and stored at -80°C for estimation of lipid profile total cholesterol (TC), triglyceride, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). The serum samples were used for the estimation of lipid profile levels using an enzymatic colorimetric method. The absorbance was measured at 540 nm using a spectrophotometer.
RESULTS
The results showed a significant decrease in serum TC, triglyceride, and very-low-density lipoprotein cholesterol levels after selenium nanoparticle supplementation compared to the control group ( < 0.05), the results indicated a significant increase in serum HDL levels after selenium nanoparticle supplementation compared to the control group ( < 0.05). This indicates that selenium nanoparticle supplementation has a beneficial effect on reducing TC levels in lambs.
CONCLUSION
The conclusion section will summarize the findings of the study and highlight the potential of selenium nanoparticles in improving lipid profiles in lambs. The implications of the study for animal nutrition and health will be discussed, along with the need for further research in this area.

Retrospective analysis of dogs and cats with a mixed form of pulmonary hypertension and suspected pulmonary capillary hemangiomatosis in comparison to animals with predomination of precapillary pulmonary hypertension.
BACKGROUND
Pulmonary capillary hemangiomatosis (PCH) is an idiopathic disease with the anomalous proliferation of a small capillary-like vessel in the pulmonary tissue, which can lead to a severe form of PH. There are only several cases of PCH described in veterinary literature: 27 cases in dogs and 2 cases in cats. In veterinary medicine, PH is mostly recognized as a consequence of left heart failure as a progression of the postcapillary PH to the precapillary form. PCH is mostly described as a primary disease, but resistant postcapillary PH with the high possibility of pulmonary edema raises speculation that PCH could be a secondary malformation to the left heart disease.
AIM
Discover the features associated with the shift between left- and right-sided heart disease in the context of PH development.
METHODS
Retrospective analysis of materials from cats and dogs with histological markers of PCH (sPCH) versus those with right heart failure (RHF).
RESULTS
Animals with histological and immunohistochemistry markers of PCH had a previous history of disease with left heart volume overload. There were no differences between the groups in radiography and gross pathology. Histologically, pulmonary fibrosis and arteriopathy could be found in RHF; in sPCH-a duplication of capillaries in alveolar septa and bizarre proliferation in surrounding structures.
CONCLUSION
PCH could be a secondary pattern of vascular remodeling due to volume overload.

BACKGROUND
infections are considered the most common foodborne pathogens responsible for zoonotic infections and food poisoning in humans and animal species such as birds. Antimicrobial resistance is considered a global anxiety because it causes human public health repercussions, as well as leads to an increase in animal morbidity and death.
AIM
The aims of this study are the isolation and identification of , as well as to investigate the antimicrobial susceptibility test (AST) and the molecular characteristics using polymerase chain reaction (PCR) and sequences for isolates from chicken products (eggs, livers, and minced meat) and human in the Wasit Governorate of Iraq.
METHODS
A total of 300 samples (150 chicken product samples including eggs, livers, and minced meat, and 150 human fecal samples) were collected from the Wasit governorate of Iraq from January to December 2022. The bacterial isolation was done according to recommendations of ISO 6579 standard and the Global Foodborne Infections Network laboratory protocol. Serotyping test and AST were done by using 19 antibiotic agents according to the recommendations of the Clinical and Laboratory Standards Institute, 2022 by using disc diffusion susceptibility test and Vitik 2 test. Finally, the suspected isolates were confirmed using the conventional PCR method and sequencing for a unique gene.

BACKGROUND
Canine cognitive dysfunction (CCD) is considered the canine version of human Alzheimer's disease (AD). As with AD, CCD is a multifactorial and progressive neurodegenerative disorder for which effective treatment options are continuously being sought. Transcranial photobiomodulation (tPBMT) or transcranial laser therapy has shown promise as a treatment for cognitive impairment in rodent AD investigations and several human AD clinical trials.
AIM
The purpose of this prospective case series was to evaluate the effect of tPBMT on cognitive scores when applied to senior dogs with CCD over a 60-day period.
METHODS
Five senior (>9-year-old) dogs with moderate (16-33) to severe (>33) cognitive scores were enrolled. Owners were instructed on the use of a Class IM laser device and administered a specific dose of laser energy transcranially to both sides of the patient's head, three times per week for one month and two times per week for a second month. No additional therapeutic measures aimed at enhancing cognitive ability were permitted during the 60-day evaluation time. Baseline cognitive scores were compared with scores obtained at 30- and 60-days post-treatment.
RESULTS
Cognitive scores showed improvement in 4/5 dogs at 30 days (27.6% reduction) and all dogs at 60 days (43.4% reduction). There were no adverse effects attributable to tPBMT.
CONCLUSION
Results of our small case series suggest that tPBMT may improve cognitive scores in dogs with moderate to severe CCD by 30 days of application and the improvement is sustained at 60 days. Further studies are needed to ascertain optimal tPBMT protocols for CCD.

BACKGROUND
Computed tomography (CT) is the gold standard for diagnosing canine nasal diseases. However, it cannot easily detect minor abnormalities in inflammatory diseases because they are not accompanied by obvious morphological changes.
AIM
The present study aimed to compare the differences in normal CT findings of turbinate structure and mucosa between breeds to establish criteria for CT diagnosis of inflammatory diseases of the nasal cavity.
METHODS
CT data from 77 dogs of 5 breeds without nasal diseases were retrospectively studied. The nasal air percentage, which reflects the volume of the nasal turbinate structure and mucosa, was measured. The nasal turbinate mucosa was measured for contrast enhancement reflecting blood flow. Measurements were performed in the ventral and ethmoid turbinate (ET) regions. Comparisons were made between breeds and sections.
RESULTS
The air percentage in the ventral and ET regions was significantly different between breeds. Contrast enhancement was significantly different between breeds only in the ET. Moreover, different breeds had different correlations between body weight, age, nose length, and air percentage.
CONCLUSION
In this study, reference values for normal CT findings of the nasal structure and mucosa were obtained, taking into account the breed, measurement section, and patient factors. The results showed that the volume of the turbinate structure and contrast enhancement of nasal mucosa differed depending on the breed. The measured values also differed depending on the cross-sections and patient factors.

BACKGROUND
Canine transmissible venereal tumor (CTVT) is a widely spread, contagious neoplasm commonly found in dogs. Mostly affects the external genitalia, however, it may also exhibit unusual clinical presentations.
AIM
To describe the epidemiology, clinical appearance, cytologic and histopathologic features of dogs with TVT in Morocco.
METHODS
Within the realm of a nation-wide study on canine and feline tumors in Morocco between September 2020 and March 2023, dogs with histologically diagnosed TVT were identified and data on epidemiologic, clinical as well as cytologic, and histologic features were compiled and analyzed.
RESULTS
A total of 64 cases of canine TVT were diagnosed. 52 dogs were cross-breed (81.2%) while 4 Siberian Huskies (6.2%) and 3 German shepherds (4.7%) were the most affected pure-breed dogs. The median age of dogs at diagnosis was 3 years (range, 1-10years) and male gender was more common (male:female ratio; 1.3:1). Tumor was located exclusively in the genital area in 58 cases (90.6%), whereas 6 dogs (9.4%) had an atypical occurrence of TVT with locations including skin and nasal cavity. Cytology allowed for an early diagnosis in 2 cases. Histology revealed no differences between the genital and extragenital forms. Immunohistochemistry was necessary in 4 cases and revealed positive staining for vimentin and Alpha-1-antitrypsin, negative marking for CD3, CD20, and AE1/AE3, and low cytoplasmic labeling for lysozyme.
CONCLUSION
CTVT is a widely distributed neoplasm in Morocco, mostly showing presence in young, cross-breed, and oftentimes stray dogs. An adequate understanding of this tumor's epidemiological features is necessary for its management and eradication.

BACKGROUND
Exercise-induced pulmonary hemorrhage (EIPH) is one of the most commonly diagnosed disorders in racehorses. Many EIPH risk factors such as breed, age, high or low environmental temperature, and distance of the race have been studied in racehorses.
AIM
The aim of this study was to study the relationship between EIPH and the presence of jugular vein thrombose in racehorses.
METHODS
Forty-eight thoroughbred racehorses randomly selected from animals with exercise intolerance due to respiratory disorders were enrolled in the present study. Clinical and tracheobronchoscopy examinations were done for EIPH grading. In addition, both jugular veins were examined using ultrasonography for vein thrombosis.
RESULTS
It was noted during endoscopy that many cases suffered from laryngeal paralysis, and we were not able to assess the degree of laryngeal paralysis under sedation. About 40% of horses with exercise intolerance suffered from EIPH of varying degrees. Most cases of jugular vein thrombosis were of the chronic type, as local heat and pain were not observed. About 42% of the exercise-intolerant horses had jugular vein thrombose with most jugular vein thrombosis on the left side. Combined jugular veins thrombose and EIPH were found in about 25% of exercise intolerance horses, while 17% showed jugular vein thrombose without EIPH, and 41% showed no EIPH with the absence of jugular vein thrombose.
CONCLUSION
The present study revealed that jugular vein thrombosis may cause disorders-associated damage to the vessels and anatomical structures close to it, such as the trachea causing EIPH.
