A silagem pode ser utilizada na alimentação de ruminantes e equídeos, sendo uma alternativa viável em épocas de estiagem. Para a produção de silagem, é importante optar por plantas forrageiras que atendam às necessidades nutritivas dos animais e que possuam características favoráveis para a conservação e aproveitamento das mesmas. Com o objetivo de preparo de um produto ensilado de qualidade, e ressaltar o uso de experimentos práticos para fins didáticos, foi realizado um ensaio demonstrativo de preparação de silagem. Neste trabalho, também foram feitas comparações de cada fase fermentativa do processo de forma visual. A metodologia empregada nesse experimento se mostrou eficaz visto os resultados obtidos em relação ao produto fabricado e a facilidade na assimilação do conteúdo por parte dos discentes, ressaltando a importância da boa conduta na produção desse alimento.(AU)

Silage can be used to feed ruminants and equines and is a viable alternative in drought times. For silage production, it is important to choose forage plants that meet the animal nutritional needs and have favorable characteristics for their conservation and use. In order to practice and learn about the ensiling good practices, a silage preparation experiment was performed and documented in video, for didactic purposes, in the forage crop discipline. In this study, each fermentation phase of the process was visually compared. The methodology used in this experiment proved to be effective given the results obtained about the manufactured product and the ease assimilation of content by students, emphasizing the importance of good practices in this food production.(AU)

The industrial manufacturing of natural products for veterinary use represents a major weakness in the veterinary sector despite increased interest and the traditional ancestral knowledge that supports them. A cross-sectional, descriptive observational study was conducted to characterize the veterinary herbal products marketed worldwide during 2018 and 2019. A comprehensive thematic search limited to the 2018-2019 period was performed in the ScienceDirect, Scopus, PubMed, Web of Science, ResearchGate, and Academic Search Complete databases. The investigation identified 487 products registered in the global market manufactured by 54 companies, led by India, The Netherlands, and the United Kingdom. The market segments of animal production and phytomedicines were dominant with 73.7% and 53.0% of products, respectively. Cattle (22.2%), sheep-goats (16.2%), and canines (16.2%) were the most favored species. The most represented therapeutic indications were those intended to treat gastrointestinal disorders (30.47%), antimicrobials (16.66%), and antiparasitic agents (10.47%). The families Fabaceae, Lamiaceae, Asteraceae, Apiaceae, Malvaceae, and Rutaceae stood out because of their frequent use, encompassing 35.0% of the 137 declared species. Andrographis paniculata (Burm.f.) Nees and Withania somnifera (Lin) Dunal were the most important species. Oral formulations for internal use (72%) and liquids (51%) in 100 mL, 500 mL, and 1 L presentations showed the highest prevalence on the market. The global market for veterinary herbal products during the 2018-2019 period was relevant in the productive and medical animal sector. No differences were found between medicinal plant species used to formulate herbal products for human and animal use.(AU)

Donkeys (Equus asinus) face a global crisis. The health, welfare, and even survival of donkeys are being compromised as the demand for their skins increases. It is driven by the production of ejiao, a traditional Chinese remedy believed by some to have medicinal properties. It is estimated that the ejiao industry currently requires approximately 4.8 million donkey skins per year. Since there is no productive chain for donkey skin production outside of China, the activity is extractive and has resulted in the decimation of donkeys. Gestation is 12 months in donkeys, increasing the risk of extinction if such practices are not controlled. In this scenario, the donkeys are collected (purchased for low prices, stolen, and collected from the side of the roads) and are then often transported for long distances, usually without water, food, or rest. The trade, in Brazil, poses significant biosecurity risks, particularly because examinations are rarely conducted and therefore infectious diseases, such as glanders and infectious anemia, remain undetected. Furthermore, in chronic stress situations, the immune system is suppressed, increasing the biosecurity risk, especially because donkeys are a silent carrier of diseases. Rarely there is traceability with animals from different origins being put together in "fake farms", before being delivered to slaughterhouses. The opportunistic strategy of collecting animals, or buying for low prices, keeping them without access to food and veterinary assistance, is what makes this trade profitable. Our experience in donkey welfare and the global skin trade suggest that it will be enormously challenging and cost-prohibitive to run a trade at the standards required to be considered humane, sustainable, and safe. Although donkeys are being blamed for the involvement in road accidents, it is not an ethical solution to maintain this trade as an alternative. Moreover, the ecological role of donkeys in native ecosystems has not been elucidated, and some studies indicate they could even have a positive effect. Regardless of the future the donkeys will have; we must guarantee a life with the least dignity to the animals under our responsibility.(AU)

Os jumentos (Equus asinus) estão enfrentando uma crise global. A saúde, o bem-estar e até a sobrevivência dos jumentos estão sendo comprometidos à medida que a demanda por suas peles aumenta. A atividade é impulsionada pela produção de ejiao, um remédio tradicional chinês que algumas pessoas acreditam possuir propriedades medicinais. Estima-se que a indústria de ejiao demande atualmente cerca de 4,8 milhões de peles de jumento por ano. Uma vez que não existe uma cadeia produtiva fora da China, a atividade é extrativista e resultou na drástica redução das populações. A gestação dos jumentos é de 12 meses, aumentando o risco de extinção se tais práticas não forem controladas. Neste cenário, os jumentos são recolhidos (comprados a preços baixos, roubados e recolhidos à beira das estradas) e são frequentemente transportados para longas distâncias, normalmente sem água, comida ou descanso. O comércio no Brasil apresenta riscos significativos de biossegurança, principalmente porque os exames raramente são realizados e, portanto, doenças infecciosas, como mormo e anemia infecciosa equina, permanecem sem detecção. Além disso, em situações de estresse crônico, o sistema imunológico é suprimido, aumentando o risco de biossegurança, principalmente porque os jumentos são portadores silenciosos de doenças. Raramente há rastreabilidade, e os animais de diferentes origens acabam sendo colocados em "fazendas fantasma", antes de serem entregues aos abatedouros. A estratégia oportunista de coletar animais, ou comprar por preços irrisórios, mantendo-os sem acesso a alimentação e assistência veterinária, é o que torna esse comércio lucrativo. Nossa experiência em bem-estar de jumentos e no comércio global de peles sugere que será extremamente desafiador e com custo proibitivo administrar um comércio dentro dos padrões exigidos para ser considerado humano, sustentável e seguro. Embora os jumentos sejam responsabilizados pelo envolvimento em acidentes rodoviários, não é uma solução ética manter este comércio como uma alternativa. Além disso, o papel ecológico dos jumentos nos ecossistemas nativos não foi elucidado, e alguns estudos indicam que eles podem até ter um efeito positivo. Independentemente do futuro que os jumentos terão, devemos garantir uma vida com o mínimo de dignidade aos animais sob nossa responsabilidade.(AU)

Introducción: La leptospirosis humana es una enfermedad zoonótica con manifestaciones clínicas inespecíficas (cefalea y mialgia), las cuales pueden confundirse con otras enfermedades febriles como: gripe, malaria, dengue, fiebre amarilla, hepatitis vírica y rickettsiosis. Objetivo: Determinar la prevalencia de anticuerpos anti-Leptospira en estudiantes de la carrera de Medicina Veterinaria y Zootecnia de la Costa Grande de Guerrero. Métodos: Se aplicó un cuestionario a los estudiantes de la Escuela Superior de Medicina Veterinaria y Zootecnia No. 3 con la finalidad de conocer algunos factores de riesgo asociados a la presencia de anticuerpos anti-Leptospira spp. La determinación de anticuerpos anti-Leptospira y la identificación de las serovariedades se realizaron con la técnica de microaglutinación. Se consideró un suero positivo cuando se observó una aglutinación en una dilución igual o mayor a 1:100. Resultados: En el estudio la seroprevalencia de anticuerpos anti-Leptospira spp. fue de 12,1 por ciento (8/66). Se detectaron anticuerpos a 8 serovariedades de Leptospira spp. El 62,5 por ciento (5/8) de los sueros presentó más de una serovariedad. Las serovariedades y frecuencia fueron icterohaemorrhagiae 25 por ciento (4/16), hardjo 18,8 por ciento (3/16), pyrogenes 18,8 por ciento (3/16), pomona 12,5 por ciento (2/16), canicola 6,2 por ciento (1/16) wolffi 6,2 por ciento (1/16) tarassovi 6,2 por ciento (1/16) y bratislava 6,2 por ciento (1/16). Los factores de riesgo estudiados no se relacionaron con la presencia de anticuerpos anti-Leptospira. Conclusiones: En el presente estudio se encontraron anticuerpos a Leptospira spp. en estudiantes de Medicina Veterinaria y Zootecnia. Por tanto, es pertinente proporcionar información a los estudiantes para prevenir el contacto con el agente causal de la leptospirosis(AU)

Introduction: Human leptospirosis is a zoonotic disease of unspecific clinical manifestations (headache and myalgia) which may be confused with those of other febrile diseases, such as influenza, malaria, dengue, yellow fever, viral hepatitis and rickettsiosis. Objective: Determine the prevalence of anti-Leptospira antibodies among Veterinary Medicine and Zootechnics students from Costa Grande de Guerrero. Methods: A questionnaire was applied to students from the Higher Education Veterinary Medicine and Zootechnics School No. 3 to obtain information about risk factors associated to the presence of anti-Leptospira spp. antibodies. Microagglutination technique was used to determine anti-Leptospira antibodies and identify serovars. A serum sample was considered positive when agglutination was observed at a dilution equal to or greater than 1:100. Results: Seroprevalence of anti-Leptospira spp. antibodies was found to be 12.1 percent (8/66). Antibodies were detected for 8 serovars of Leptospira spp. Of the serum samples analyzed, 62.5 percent (5/8) contained more than one serovar. The serovars and their frequency were the following: icterohaemorrhagiae 25 percent (4/16), hardjo 18.8 percent (3/16), pyrogenes 18.8 percent (3/16), pomona 12.5 percent (2/16), canicola 6.2 percent (1/16), wolffi 6.2 percent (1/16), tarassovi 6.2 percent (1/16) and bratislava 6.2 percent (1/16). The risk factors studied were not related to the presence of anti-Leptospira antibodies. Conclusions: Leptospira spp. antibodies were found in Veterinary Medicine and Zootechnics students. It is therefore advisable to provide students with the information required to prevent contact with the causative agent of leptospirosis(AU)

Canine Hip Dysplasia (CHD) is a highly prevalent articular pathological condition. In this sense, radiography becomes an important diagnostic method to determine the presence and severity of the disease. The objective was to create 3D models and their respective radiographs representing the CHD (3D AMCHD). The research was carried out in the Laboratory of 3D Educational Technologies of UFAC, under no. 23107.007273/2017-49 (CEUA/UFAC). A canine skeleton (hip bone, femurs and patellae) was used without anatomical deformities compatible with DCF (pelvis, femurs and patella), which were scanned in order to obtain the files of the base model. In these files the deformations representing the different degrees of CHD were performed. Subsequently, the 3D AMCHD files were printed, mounted and X-rayed. The 3D AMCHD represented the bone deformations of the different degrees of CHD. In the radiographs of the 3D AMCHD it was possible to observe and determine each of the bones that constituted the hip joints. This allowed to reproduce the correct positioning to represent the CHD diagnosis and establish the precise points to determine the Norberg angle. In this way, it was evidenced that the 3D AMCHD can be a possible tool to be used in the Teaching of Veterinary Medicine.(AU)

A displasia coxofemoral canina (DCF) é uma condição patológica articular de grande prevalência. Nesse sentido, a radiografia torna-se um método de diagnóstico importante para determinar a presença e a gravidade da doença. O objetivo do presente trabalho foi criar modelos 3D e suas respectivas radiografias representando a DCF (MADCF 3D). A pesquisa foi realizada no Laboratório de Tecnologias Educacionais 3D da UFAC, sob o nº. 23107.007273/2017-49 (Ceua/Ufac). Foram utilizados esqueletos caninos (pelve, fêmures e patelas) sem deformidades anatômicas compatíveis com a DCF, os quais foram digitalizados a fim de se obterem os arquivos do modelo base. Nesses arquivos foram realizadas as deformações que representavam os diferentes graus da DCF. Posteriormente, os arquivos dos MADCF 3D foram impressos, montados e radiografados. Os MADCF 3D representaram as deformações ósseas dos diferentes graus da DCF. Nas radiografias dos MADCF 3D, foi possível observar e determinar cada um dos ossos que constituíam as articulações coxofemorais. Isso permitiu reproduzir o posicionamento correto para representação do diagnóstico DCF e estabelecer os pontos precisos para determinar o ângulo de Norberg. Dessa forma, evidenciou-se que os MADCF 3D podem ser uma possível ferramenta a ser empregada no ensino de medicina veterinária.(AU)

Resumo Na perspectiva da teoria enativa da cognição, uma habilidade pode ser compreendida como uma relação flexível de um organismo com aspectos de seu ambiente de modo que ele possa agir de forma bem sucedida. Por sua vez, o conceito de políticas cognitivas nos ajuda a compreender como habilidades são promovidas e distribuídas em diversos contextos. Consideramos que os modelos de avaliação da produtividade acadêmica promovem arranjos que tendem a enfatizar um plano no qual os resultados ganham maior relevância na escala produtiva do que o desmembramento das "soluções" já existentes em problemas. Sendo assim, o objetivo deste artigo é entender o modo como as formas de avaliação dos programas de pós-graduação no Brasil podem modular noções de habilidades acadêmicas - hoje baseadas, principalmente, em publicações, invisibilizando outros processos que envolvem a produção de conhecimento e a experiência do pesquisador. Para tanto, realizamos uma pesquisa-intervenção junto a estudantes de cinco programas de pós-graduação de universidades públicas e privadas, na qual foram utilizados os procedimentos de entrevistas semiestruturadas e oficinas de fotografia. Por meio das entrevistas com as estudantes de engenharia e o estudante da veterinária, destacadas neste artigo, percebemos como o funcionamento acadêmico pressupõe a habilidade de pesquisar como um atributo que pertence ao indivíduo e reconhece/visibiliza em maior quantidade as habilidades consagradas nas sessões de procedimentos em métodos de artigos científicos, tratando como expert aquele que reproduz com precisão modos de fazer previamente especificados.

Abstract From the perspective of the enative theory of cognition, an ability can be understood as a flexible relationship of an organism with aspects of its environment so that it can act in a successful way. In turn, the concept of cognitive policies allows to understand how skills are promoted and distributed in diverse contexts. We consider that the models of evaluation of academic productivity promote more relevant results than transformation of existing "solutions" into problems. The objective of this article is to understand how the forms of evaluation of graduate programs in Brazil modulate a notion of academic abilities based, mainly, in publications, decreasing the importance of other processes involving the production of knowledge and the experience of the researcher. For such, we conducted an intervention research with students from five graduate programs of public and private universities utilizing semi-structured interviews and photography workshops. The results show how academic functioning assumes the ability to research as an attribute that belongs to the individual. They emphasise the abilities acknowledged only in scientific methods, considering as experts students able to reproduce standard practices.

Resumen En la perspectiva de la teoría enactiva de la cognición, una habilidad se entiende como una relación flexible de un organismo con aspectos de su ambiente para que pueda actuar de forma exitosa. Por su parte, el concepto de políticas cognitivas nos ayuda a comprender cómo las habilidades son promovidas y distribuidas en diversos contextos. Consideramos que los modelos de evaluación de la productividad académica promueven arreglos que tienden a enfatizar un plan en el cual los resultados ganan mayor relevancia en la escala productiva que el desmembramiento de las "soluciones" ya existentes en problemas. Ante esto, el objetivo de este artículo fue entender cómo las formas de evaluación de los programas de posgrado en Brasil pueden modular nociones de habilidades académicas, basadas actualmente en publicaciones, invisibilizando otros procesos que involucran la producción de conocimiento y la experiencia del investigador. Para ello, realizamos una investigación-intervención junto a estudiantes de cinco programas de posgrado de universidades públicas y privadas, en la cual se utilizaron los procedimientos de entrevistas semiestructuradas y talleres de fotografía. De las entrevistas con las estudiantes de ingeniería y el estudiante de veterinaria, destacadas en este artículo, percibimos cómo el funcionamiento académico presupone la habilidad de investigar como un atributo que pertenece al individuo y reconoce/posibilita en mayor cantidad las habilidades más consagradas en las sesiones de procedimientos en métodos de artículos científicos tratando como experto aquel que reproduce con precisión modos de hacer previamente especificados.

BACKGROUND: Gross anatomy and sectional anatomy of a monkey should be known by students and researchers of veterinary medicine and medical research. However, materials to learn the anatomy of a monkey are scarce. Thus, the objective of this study was to produce a Visible Monkey data set containing cross sectional images, computed tomographs (CTs), and magnetic resonance images (MRIs) of a monkey whole body. METHODS: Before and after sacrifice, a female rhesus monkey was used for 3 Tesla MRI and CT scanning. The monkey was frozen and sectioned at 0.05 mm intervals for the head region and at 0.5 mm intervals for the rest of the body using a cryomacrotome. Each sectioned surface was photographed using a digital camera to obtain horizontal sectioned images. Segmentation of sectioned images was performed to elaborate three-dimensional (3D) models of the skin and brain. RESULTS: A total of 1,612 horizontal sectioned images of the head and 1,355 images of the remaining region were obtained. The small pixel size (0.024 mm × 0.024 mm) and real color (48 bits color) of these images enabled observations of minute structures. CONCLUSION: Due to small intervals of these images, continuous structures could be traced completely. Moreover, 3D models of the skin and brain could be used for virtual dissections. Sectioned images of this study will enhance the understanding of monkey anatomy and foster further studies. These images will be provided to any requesting researcher free of charge.

The magnetic resonance (MR) features of spinal epidural hemorrhage depending with the passage of time have a meaning in veterinary medicine. The aim of this study is to propose the characteristic MR image of spinal epidural hemorrhage using a lower field permanent magnet scanner in dogs. A total of 8 clinically normal beagle dogs, weighing about 9 kg, were allocated. After a baseline MR examination, spinal epidural hemorrhage was created. MR scanning was executed on days 1, 2, 3, 4, 5, 10, 15, 20, 25, and 30 using 0.25 Tesla low field MR. Transverse MR images were attained for image examination. T2W, T1W, fluid-attenuated inversion recovery (FLAIR), short tau inversion recovery (STIR), and T2*-GRE sequences were used. Images were compared subjectively for signal transition assessment. Spinal epidural hemorrhage models were produced positively in 8 dogs at the T12 to L2 region. Initially, the spinal cord and epidural lesions were hyper-intense on T2W and T1W images. On T2W, FLAIR and STIR images, the spinal cord lesion was steadily hyperintense. No significant and consistent hypointense signal indicating hemorrhage was seen on T2*-GRE images. This study result suggests that relatively consistent hyperinstensity on T2 and FLAIR is observed for 30 days, meanwhile T2*-GRE imaging is less useful in hemorrhage detection.

Susceptibility-weighted imaging (SWI) is a magnetic resonance imaging (MRI) sequence used for evaluating traumatic brain injury (TBI). Although SWI is being increasingly used in veterinary medicine, there are no systematic studies regarding its use. We aimed to evaluate TBI lesions by using conventional MRI and SWI in 11 dogs and determine the correlation between clinical status and conventional MRI or SWI findings. The modified Glasgow coma scale (MGCS) at presentation and a previously used MRI grading system (MRGr; grades 1–6) were used to evaluate the brain lesions, and correlations between MGCS score and each MRGr were assessed. Conventional MRI revealed 23 lesions in 11 dogs with variable MGCS scores (range: 11–17). SWI showed comparable findings for all of the lesions except for subdural hemorrhage, and it revealed additional lesions in four dogs. The median MRGr was 2 on both conventional MRI and SWI. The MRGr of the conventional MRI assessments and the MGCS scores showed a significant negative correlation (r = −0.685). In conclusion, SWI had better TBI lesion-detection ability, but conventional MRI had a better correlation with early clinical status and subdural hemorrhage. Thus, a combination of conventional MRI and SWI examinations can improve TBI diagnosis in dogs.

Enrofloxacin, a fluoroquinolone, is a broad-spectrum antibiotic widely used in veterinary medicine that inhibits the action of bacterial DNA gyrase, resulting in anti-bacterial effects. This study was performed to examine whether enrofloxacin has modulatory and anti-inflammatory activity on immune cells. A few studies have reported the anti-inflammatory effects of enrofloxacin. In this study, we used mouse spleen cells treated with lipopolysaccharide (LPS) and examined the effects of enrofloxacin. Several assays were performed in LPS-treated spleen cells after the enrofloxacin treatment. Enrofloxacin inhibited the metabolic activity and mitochondrial membrane potential of LPS-treated spleen cells significantly. On the other hand, enrofloxacin did not alter the proportion of the subsets in spleen cells, and did not induce cell death. The production of tumor necrosis factor-alpha in LPS-treated spleen cells was inhibited by enrofloxacin. Overall, enrofloxacin had modulatory activity in spleen cells treated with LPS. These data may broaden the use of enrofloxacin as an antibiotic with anti-inflammatory activity in veterinary clinics.

It was aimed to determine the anatomical structures in thoracic cavity by computed tomography imaging (CT) and compare the cross sectional images in the same specimens which were plastinated after CT imaging. It was also aimed to obtain 3 dimensional (3D) reconstructions of thoracic anatomical structures. Thoracic organs of 3 adult cats were CT imaged and then plastinated in this study. Specimens were plastinated in the same body position in the CT imaging process. CT images and corresponding plastinated cross sections were compared to each other. Anatomical structures of the thoracic cavity in plastinates were in accordance with CT images. Beside the bony structures, other organs such as esophagus, trachea, heart with related vessels, lungs and thoracic muscles were well defined in CT images and plastinates. Moreover, 3D reconstructed images of anatomical structures of thoracic cavity were acquired well. This study is thought to be beneficial for veterinary surgery and radiology fields as well as veterinary anatomy educations.

El objetivo de este trabajo consistió en determinar las estructuras anatómicas en la cavidad torácica mediante tomografía computarizada (TC) y comparar las imágenes transversales en las mismas muestras, que fueron plastinadas después de la TC. También se pretendía obtener reconstrucciones tridimensionales (3D) de estructuras anatómicas torácicas. Se tomaron imágenes de los órganos torácicos de 3 gatos adultos por TC y luego se plastinaron en este estudio. Las muestras se plastinaron en la misma posición corporal en el proceso de obtención de imágenes TC. Las imágenes de TC y las secciones transversales plastinadas correspondientes se compararon entre sí. Las estructuras anatómicas de la cavidad torácica en los preparados plastinados estaban de acuerdo con las imágenes de CT. Además de las estructuras óseas, otros órganos como el esófago, la tráquea, el corazón con vasos relacionados, los pulmones y los músculos torácicos estaban bien definidos en las imágenes de TC y los plastinados. Por otra parte, se captaron bien las imágenes reconstruidas en 3D de las estructuras anatómicas de la cavidad torácica. Pensamos que este estudio es beneficioso para la cirugía veterinaria y los campos de radiología, así como también para la educación de anatomía veterinaria.

Ectoparasitism in animals has become an issue of great concern that needs to be resolved to prevent huge economic losses occurring to livestock industry all over the world. Synthetic adrugs have been playing a major role in controlling ectoparasites, but their frequent and irrational use has resulted in drug resistance to routinely used chemicals and their residual effects on food and environment. Therefore, this approach of using chemical acaricides and insecticides is losing its popularity and effectiveness in controlling ectoparasites. So, the development of alternative approaches in ectoparasite management is currently required. Among alternative protocols, plants and their essential oils have played remarkable role in controlling different ectoparasites (ticks, flies, mites, lice) of veterinary importance. Essential oils have been proved to be cheaper, more effective and safer therapeautic agents against different ectoparasites of livestock importance.

En los animales el ectoparasitismo se ha convertido en un tema de gran preocupación que debe resolverse para evitar que se produzcan grandes pérdidas económicas para la industria ganadera en todo el mundo. Los aditivos sintéticos han desempeñado un papel importante en el control de los ectoparásitos, pero su uso frecuente e irracional ha dado como resultado la resistencia a los fármacos utilizados habitualmente y efectos residuales sobre los alimentos y el medio ambiente. Por lo tanto, el enfoque basado en el uso de acaricidas e insecticidas químicos está perdiendo popularidad y efectividad en el control de los ectoparásitos. Por lo tanto, actualmente se requiere el desarrollo de enfoques alternativos en el manejo de ectoparásitos. Entre los protocolos alternativos, las plantas y sus aceites esenciales han jugado un papel notable en el control de diferentes ectoparásitos (garrapatas, moscas, ácaros, piojos) de importancia veterinaria. Se ha demostrado que los aceites esenciales son agentes terapéuticos más baratos, más efectivos y más seguros contra diferentes ectoparásitos de importancia ganadera.

ABSTRACT The traumatic accidents which result in fractures and even in impairment of a bone segment have a high prevalence in routine veterinary surgery. Many times these fractures are complex and difficulty healing or need bone grafts to preserve and restore the length of the affected limb. Thus, the recovery time of these animals is usually delicate and long, with complications risks, such as delayed union and non-union of the fractured bone segments or absence of graft incorporation. In this sense, the stem cells (SC) have shown to be a strong ally of the orthopedic doctors due to their capacity to provide osteoprogenitor cells, to increase the osteoinductive effect minimize the healing time and provide a greater efficiency to the repairing process. Due to that, before the expectation of their assignments, this review aims to describe the stem cells characteristics, their current applications in the fractures healing and, especially, their contribution to the bone grafts consolidation.

RESUMEN Los accidentes traumáticos que resultan en fracturas y hasta en el comprometimiento de un segmento óseo tienen alta prevalencia en la rutina quirúrgica veterinaria. Muchas veces esas fracturas son complejas y presentan dificultades de cicatrización o necesitan de injertos óseos para preservar y restaurar el largo del miembro acometido. De esa forma, el tiempo de recuperación de esos animales suele ser delicado y prolongado con riegos de complicaciones, como unión retardada y no unión de los segmentos óseos fracturados o ausencia de incorporación de los injertos. En este sentido, las células-madre (CT) vienen demostrando ser una fuerte aliada de los ortopedistas debido a su capacidad en proveer células osteoprogenitoras, de incrementar el efecto osteoinductor, minimizar el tiempo de cicatrización y proporcionar mayor eficiencia al proceso reparador. Frente a la expectativa de sus atribuciones, la presente revisión tiene por objetivo describir las características de las células-madre, sus aplicaciones actuales en la cicatrización de fracturas y, especialmente, su contribución en la consolidación de injertos óseos.

Respiratory inflammation is a frequent and fatal pathologic state encountered in veterinary medicine. Although diluted bee venom (dBV) has potent anti-inflammatory effects, the clinical use of dBV is limited to several chronic inflammatory diseases. The present study was designed to propose an acupoint dBV treatment as a novel therapeutic strategy for respiratory inflammatory disease. Experimental pleurisy was induced by injection of carrageenan into the left pleural space in mouse. The dBV was injected into a specific lung meridian acupoint (LU-5) or into an arbitrary non-acupoint located near the midline of the back in mouse. The inflammatory responses were evaluated by analyzing inflammatory indicators in pleural exudate. The dBV injection into the LU-5 acupoint significantly suppressed the carrageenan-induced increase of pleural exudate volume, leukocyte accumulation, and myeloperoxidase activity. Moreover, dBV acupoint treatment effectively inhibited the production of interleukin 1 beta, but not tumor necrosis factor alpha in the pleural exudate. On the other hand, dBV treatment at non-acupoint did not inhibit the inflammatory responses in carrageenan-induced pleurisy. The present results demonstrate that dBV stimulation in the LU-5 lung meridian acupoint can produce significant anti-inflammatory effects on carrageenan-induced pleurisy suggesting that dBV acupuncture may be a promising alternative medicine therapy for respiratory inflammatory diseases.

Mesenchymal stem cells (MSCs) have desirable characteristics for use in therapy in animal models and veterinary medicine, due to their capacity of inducing tissue regeneration and immunomodulation. The objective of this study was to evaluate the differences between canine adipose tissue-derived MSCs (AD-MSCs) extracted from subcutaneous (Sc) and visceral (Vs) sites. Surface antigenic markers, in vitro differentiation, and mineralized matrix quantification of AD-MSCs at different passages (P₄, P₆, and P₈) were studied. Immunophenotypic analysis showed that AD-MSCs from both sites were CD44+, CD90+, and CD45−. Moreover, they were able, in vitro, to differentiate into fat, cartilage, and bone. Sc-AD-MSCs preserve in vitro multipotentiality up to P₈, but Vs-AD-MSCs only tri-differentiated up to P₄. In addition, compared to Vs-AD-MSCs, Sc-AD-MSCs had greater capacity for in vitro mineralized matrix synthesis. In conclusion, Sc-AD-MSCs have advantages over Vs-AD-MSCs, as Sc AD-MSCs preserve multipotentiality during a greater number of passages, have more osteogenic potential, and require less invasive extraction.

Fluoroquinolone (FQ) antibiotics are an important class of synthetic antibacterial agents. These are the most extensively used drugs for treating bacterial infections in the field of both human and veterinary medicine. Herein, the antibacterial and pharmacological properties of four fluoroquinolones: lomefloxacin, norfloxacin, ciprofloxacin, and ofloxacin have been studied. The objective of this study was to analyze the antibacterial characteristics of the different fluoroquinolones. Also, the pharmacological properties of the compounds including the Lipinski rule of five, absorption, distribution, metabolism, and excretion, LD50, drug likeliness, and toxicity were evaluated. We found that among all four FQ molecules, ofloxacin showed the highest antibacterial activity through in silico assays with a strong interaction (−38.52 kJ/mol) with the antibacterial target protein (topoisomerase-II DNA gyrase enzyme). The pharmacological and pharmacokinetic analysis also showed that the compounds ciprofloxacin, ofloxacin, lomefloxacin and norfloxacin have good pharmacological properties. Notably, ofloxacin was found to possess an IGC50 (concentration needed to inhibit 50% growth) value of 0.286 μg/L against the Tetrahymena pyriformis protozoa. It also tested negative for the Ames toxicity test, showing its non-carcinogenic character.
