Resumo: O objetivo deste estudo foi o de caracterizar lesões musculares em cães com Distrofia Muscular do golden retriever (DMGR), de diferentes idades, por análises histopatológica e imunoistoquímica. Foram utilizados vinte e cinco cães machos classificados e distribuídos em grupos de acordo com a idade: grupo I - distróficos até 1 ano; grupo II - distróficos acima de 1 ano; grupo III - controle até 1 ano; grupo IV - controle acima de 1 ano. Uma amostra de cada músculo foi fixada em solução de formol, processadas pelas técnicas usuais de inclusão em parafina, coradas com HE e TGM para análise histopatológica e processadas para a análise imunoistoquímica de linfócitos T-CD3+, antígeno MHC II e vimentina. Outras amostras foram congeladas em nitrogênio líquido e processadas pelas técnicas usuais para realização das reações imunoistoquímicas para marcação dos linfócitos T-CD4+, TCD8+ e do antígeno MHC I. Os resultados mostraram que as lesões nos músculos distróficos do grupo I foram moderadas comparativamente às do grupo II que foram severas. Nos músculos distróficos, os linfócitos T-CD3+, T-CD4+ e T-CD8+ concentravam-se nas áreas de degeneração e necrose. O número de linfócitos T-CD3+ e T-CD4+ foi significativamente maior (p < 0.05) em todos os músculos distróficos em comparação aos controles, demonstrando a participação dos linfócitos T na doença. O número de linfócitos T-CD8+ foi significativamente maior (p < 0.05) nos distróficos, exceto para os músculos sartório cranial no grupo I, diafragma e bíceps femoral no grupo II.

Abstract: The purpose of this study was to characterize the lesions in dystrophic muscles of DMGR dogs of different ages, by means of histopathological and immunohistochemistry analysis. Twenty-five male dogs were classified and distributed into groups according to the age: Group I - dystrophic up to 1 year, group II - dystrophic over 1 year, group III - control up to 1 year, group IV - control over 1 year. One sample from each muscle was fixed in formalin solution, processed by usual techniques of paraffin embedding, stained with HE and TGM for histopathological purposes and processed for immunohistochemical analysis of the distribution of T-lymphocytes CD3+, MHC II and vimentin. Other samples were frozen in liquid nitrogen, processed by usual techniques of freezing in order to perform the techniques of immunohistochemical labelling for CD4+ T-lymphocytes, T-CD8+ and MHC I. The results of histopathological analysis showed that the lesions in dystrophic muscles in the Group I were moderate compared to that ones in the Group II which were severe. The CD3+, CD4+ and CD8+ Tlymphocytes were more numerous in dystrophic muscles especially in areas of degeneration and necrosis. The number of CD3+ and CD4+ T-lymphocytes was found to be significantly higher (p <0.05) in all dystrophic muscles compared to controls demonstrating the involvement of T-lymphocytes in the disease. The number of CD8+ Tlymphocytes was found to be significantly higher (p <0.05) in dystrophics, except for the cranial sartorius muscles in the Group I and the diaphragm and biceps femoris in the Group II. The immunoexpression of MHC I increased with age in dystrophic animals, in contrast to MHC II that remained the same. The immunoexpression of vimentin and VEGF in the dystrophic muscles was mild (score 1) upon all muscles. From these results we can conclude that in dystrophic muscle immunoexpression of...

Full textThe dog GRMD (Golden Retriever Muscular Dystrophy) is an excellent model to study the action of cell therapy for application to DMD - from Duchenne Muscular Dystrophy, which occurs in humans; clinic due to the similarity between the two. These diseases have in common the legacy recessive linked to chromosome X, and are caused by the absence of a protein called dystrophin, which is present in sarcolema of muscle fibers. The point of the structure of mutation in the dystrophin gene is responsible for the phenotype GRMD, and you can find individuais with c1inical features quite different from each other. Currently there is no specific treatment for Duchenne muscular dystrophy, and the studies on the c1inical development of muscular dystrophy and morphological aim, through constant assessments, establish a standardized phenotypic for these animais in order to monitor pre-clinical results properly and maintain a good quality of life for them so that they have conditions to be submitted to the protocols of cell therapy being developed as kennel GRMD Brazil, and with it, knowing clearly the effective action of cell therapy versus the morphological development of this progressive degenerative disease of dogs. It was checked the c1inical and morphological of 12 dogs GRMD, 06 females and 06 males, from birth to 12 months of age. Judging by the locomotive system, it was noted that among the first (five months old) and last assessment (12 months), there was a worsening trend with significant asymmetry in posture, increasing the angle of the tarsus and carpus, adduction of the members, decoupling of the pelvic belt, as well as changes in the mobility of active knees during the activity running. Reproductive assessment of dystrophic dogs indicated higher rates of abnormal sperm (defects larger and smaller) compared to normal dogs at 12 months of age, while females expressed sexual maturity to 09 months. The monthly blood monitoring showed values close to ideal for healthy dogs, and the examinations performed with the animais between six and twelve months of age were those who indicated major changes in relation to the baseline for the species. Average concentrations for red blood cells, hemoglobin and hematocrit were lower than the average for this age group. As for serum biochemical assessments, CK is an important tool for diagnosis and monitoring muscular dystrophy in dogs, due to its indisputable fluctuations and increases in individuais patients. AL T and AST also showed increases greatly above the normal values for ali ages evaluated. Finally, the cardiac parameters measured in dystrophics dogs were significantly different compared to those found in normal healthy dogs, but without the deficit in cardiac physiology GRMDs

Full textDuchenne muscular dystrophy is a neuromuscular disorder caused by the mutation or deletion of the dystrophin gene, which is linked to chromosome X. Recent studies have shown the important role of dystrophin in the CNS, and its related defect with a variety of abnormalities in the function of CNS, such as behavior and cognitive dysfunction. The most suitable animals models for these studies are those with the most similar clinical picture to DMD found in humans, as Golden Retriever dogs with muscular dystrophy (GRMD). There are no further studies on the GRMD animal CNS, and the aim of this study was to analyze the morphology of the brain of GRMD and not dystrophic animals through macroscopic analysis using measurement and photographic registration methods, and microscopic analysis using the modified cresyl violet staining technique. However, using the proposed methodology, we could not find significant differences in the brain when comparing the dystrophic animals and non-dystrophic, which is in agreement with the literature for DMD using the same parameters. In time, there is individual variation in dog brain morphology, whether they are animals of the dystrophic group or controls. Other techniques should be applied in order to elucidate the consequences of the total or partial absence of dystrophin in the CNS

Full textPhysiotherapy has been widely used as support treatment for muscular dystrophies. Its effect on dystrophic muscle and global function should be better understood to guide treatments. This study aims to understand the role of motor physical therapy on muscular collagen deposition and some kinematics and dynamical parameters of gait of the Golden Retriever Muscular Dystrophy (GRMD) model. Five GRMD dogs with the same age had fragments of biceps femoralis collected by biopsy for light microscopy and Immunohistochemistry analysis. Gait of the dogs were video recording for kinematics analysis and Ground Reaction Forces (GRF) in vertical (Fy), craniocaudal (Fx) and mediolateral (Fz) direction were collect using a Force Plate Kistler AG (9287A/100Hz) and normalized for body weight. Two animals (therapy dogs: TD) underwent a protocol which consisted of velocity controlled walking activity in an area of 288 meters total length, 3 times/week per 12 weeks. Control dogs (CD) maintained their daily routine. Zero time (t0) is considered at collect I (n=5) and time after therapy (t1) - collect II. Statistical analysis considered p<.01. Immunohistochemistry anticollagen types I, III (Calbiochem®) and IV (Bioreagents®) were performed. Histopathology features were observed at t0. CD presented hypercontracted fibers that were not observed on TD at t1. Collagen types I and III were the most increased ones. At t1, thicker tracts of collagen type I were observed at the endomysium of TD compared to t0. GRMD dogs presented slow velocity of gait (0.64 m.s-1) at t0 and there were a decrease of this velocity of TD at t1 (0.45 m.s-1). Hip ROM was decrease at t1 (p<.0001), as well as the shoulder ROM (p<.05) for TD. Stifle and Carpal ROM presented the highest active ROM during gait of dystrophic dogs. Fy of thoracic and pelvic limbs at t1 of TD and CD was higher than t0. CD presented increase of support time of thoracic limbs at t1 (49 to 53%). Propulsive force (Fx-) of GRMD dogs were decrease at t0, with no effect of physical therapy. Medial force (Fz+) of TD thoracic limbs were higher at t1 when compared to CD (p<.0001). TD presents less muscular flexibility and regeneration when compared to CD. Functionally, the muscular weakness of dystrophic dogs reflects a gait with slow velocity, overloaded and difficulty to goes forward. Moreover, TD presented lower range of motion of the proximal joints when compared to t0. The applied motor physical therapy accelerates the morphological alterations on dystrophic muscle without stop the gait disorders of the canine model of Duchenne muscular dystrophy.

Full textThe aim of the present research was to evaluate the reproductive condition of Golden Retriever dogs affected by muscular dystrophy. Breeding soundness examination was performed in 11 male dogs aged between 10 months and 4 years. Seven of this total were affected by muscular dystrophy and 4 healthy dogs that served as control. All dogs were submitted to a through physical exam, seminal evaluation and ultrasound of the reproductive tract. Testicle and spermatic cord morphology of post-mortem dogs were also examined. The following alterations were observed for the affected dogs: muscular atrophy, stiff walk, aspiration pneumonia, diaphragmatic fragility with stomach projection to the torax, megaesophagus e dilated cardiomyopathy. In relation to the genital tract, two dogs presented with bilateral cryptorchidism. Semen evaluation revealed high percentage of major and total sperm defects in affected dogs. Ultrasonographic exams were similar among healthy and affected dogs. Histophatology of the testicle and cremaster muscle revealed morphologic alterations in affected dogs represented by degeneration and muscular retraction with miocyte hyalinization, respectively. In conclusion, affected Golden Retriever dogs have their reproductive performance compromised by the muscular dystrophy.

Full textThe experimental dog model Golden Retriever affected by muscular dystrophy (GRMD) is the most appropriate substitute among animal models to study Duchenne Muscular Dystrophy. The main clinical signs observed in affected dogs are dysfagy, tongue hypertrophy, progressive weight loss, weakness, splaying of the limbs and contractures. The disease is due to the absence of dystrophin, a transmembrane muscle protein, which has a vital role on the maintence of structure and function of the muscle cell. GRMD doesn?t affect only skeletal muscle, also acted including in the digestory tract function, since the smooth muscle corresponds to0 the primary component of the digestive tube. The aim of this study was to evaluate, through of morphologic studies, if the muscular dystrophy affects the general architecture of digestory tract and how is arranged its muscular structure. There were evaluated the tubular viscera of GRMD affected dogs, through gross and light microscopic description, stained with Hematoxilin and Eosin, Masson trichrome and Picrossirus technique. Jointly, nine GRMD affected dogs were submitted on evaluation of the establishment of a new alimentary management, during a year, directed to the correction of problems involved on the dysphagy of dystrophic dog. The esophagus and the stomach presented the most affected portions. Muscle fibers presents varied diameter and were intermixed with abundant connective tissue, fibroblast and mononuclear infiltrate. The esophagus presents severe alterations, reflecting on its functionability, and leading to secondary megaesophagus, due to total constitution of striated muscle. The gut doesn?t presented significative histopathologic alterations. There was observed difference of severity between lesions that occurs on the striated muscle and the smooth muscle, and this fact could be due to the distinct distribution of the dystrophin-glycoprotein complex that occurs in these types of muscles. In this way, the absence of dystrophin was inclined to be less critical to the function of the intestine smooth muscle than of the skeletal striated muscle. The stomach smooth muscle presented more affected than the intestine smooth muscle, being explained to the fact of the first to suffer more contraction and distention cycles, which results in increase of collagen area on the muscle tissue and consequently, loss of its architecture. On the GRMD affected dog, the apprehension is a critical phase. There were significative answers on new management, since those phases was substituted by human relief. The mechanic regurgitation was inclined to zero and seems to decrease the excessive energetic caloric burned. The way which was offered the food and water warned the occurrences of aspiration pneumonia. The amount of water added to dry food was enough to hidric maintenance. The present management determined weight maintenance, absence of clinic dehydration and absence of death, being indicated as basal management to be applied on the dysphagy and secondary megaesophagus acquired in the muscular dystrophy. Concluding, the management adequately directed became especially important to warn complications and reflects on maintenance of the balance and strength of immune system, consequently, support in front of the disease, given then life with quality

Golden Retriever Muscular Dystrophy (GRMD) is the best natural model of Duchenne muscular dystrophy (DMD) with genotypic and phenotypic manifestations similar the human disease. As in to DMD patients, the progressive proliferation of connective tissue in the endomysium of the muscle fibers is parallel to the clinical course of disease in GRMD animals. Studies indicate the relationship of mast cells with the deposition of fibrous tissue due to the release of mediators that activate fibroblasts. The aim of this study was to evaluate the expression of mast cells and its possible relation with muscle injury and fibrosis in GRMD dogs at different ages. It was used fragments of four skeletal muscle groups (masseter, diaphragm, triceps brachial and biceps femoris) of ten dogs between two and eight months age, six affected and four controls. Samples were processed by usual techniques of histology, stained with hematoxylin-eosin and toluidine blue, to verify the expression of mast cells, and Azan trichrome for evaluation and quantification of fibrous. In all muscle groups of dogs GRMD the infiltration of mast cells increased significantly compared to control group. The average number of mast cells decreased with the age of GRMD dogs. All muscle groups showed a significant increase in the amount of collagenous tissue in the control group. The deposition of fibrous tissue decreased with the age of the animals. Possibly, the increase of mast cell degranulation and mediator release would occur in younger GRMD dogs (2 months), fact that potentiated the increase deposition of fibrous tissue in muscle fibers which was gradually decreasing over time and age of the animals. Other studies are needed to clarify the role of mast cells in the pathogenesis of fibrosis in order to contribute to the development of new therapeutic approaches and improve the life expectancy of humans and dogs affected by muscular dystrophy

Studies indicate the relationship of mast cells with the deposition of fibrous tissue due to the release of mediators that activate fibroblasts. The aim of this study was to evaluate the expression of mast cells and its possible relation with muscle injury and fibrosis in GRMD dogs at different ages. It was used fragments of four skeletal muscle groups (masseter, diaphragm, triceps brachial and biceps femoris) of ten dogs between two and eight months age, six affected and four controls. Samples were processed by usual techniques of histology, stained with hematoxylin-eosin and toluidine blue, to verify the expression of mast cells, and Azan trichrome for evaluation and quantification of fibrous. In all muscle groups of dogs GRMD the infiltration of mast cells increased significantly compared to control group. The average number of mast cells decreased with the age of GRMD dogs. All muscle groups showed a significant increase in the amount of collagenous tissue in the control group. The deposition of fibrous tissue decreased with the age of the animals. Possibly, the increase of mast cell degranulation and mediator release would occur in younger GRMD dogs (2 months), fact that potentiated the increase deposition of fibrous tissue in muscle fibers which was gradually decreasing over time and age of the animals. Other studies are needed to clarify the role of mast cells in the pathogenesis of fibrosis in order to contribute to the development of new therapeutic approaches and improve the life expectancy of humans and dogs affected by muscular dystrophy

Full textThe dogs Golden Retriever with Muscular Dystrophy (GRMD) are considered experimental models for study of the Muscular Dystrophy of Duchenne that acomete human, and they are genetically homologue. We use the muscular ultrasound to evaluate the therapeutical evolution of injection of stem cells (SC). For this experiment we use 8, being 6 affected for disease and 2 not affected (carrying and male normal). We evaluate of qualitative form (visual) and quantitative (digital) the cervical muscles splenius and capitis semispinalis and the pelvic muscle semitendinosus and carry through muscular mensure. In relation to the cervical muscles we verify that it does not have visual alteration in the architecture of fibres, however the treat dog saw arterial presented minors props up in the digital analysis in relation the dog has controlled affected, leaving suspicion on the migration of SC in this muscular group. Splenius presented greater echogenicity that the muscle semispinalis capitis in 7 animals. For the muscle semitendinosus, the carrier presented high echogenicity; the affected ones had presented variable degrees of alteration of the muscular architecture and increase of echogenicity; the normal male presented regular fibres, however in some examinations he presented high echogenicity being able to be consequence of the transducer angle. How much to the mensure, it has difference between the affected ones and not affected for the muscle splenius and due to hypertrophy that affects the pelvic muscles, it was not possible to establish differences between the two groups. We conclude that the ultrasonography with transducers of up to 7,5 MHz is not viable to follow therapeutical evolution of injection of SC in muscles with the pseudohypertrophy of GRMD, had the severe modification of the architecture, not being possible the detention of probable repairs of the muscle.
