The biosafety of innovative procedures that utilize stem cells in regenerative medicine has been addressed in several studies. Previous work has showed no tumour formation following the use of feline and human amniotic membrane-derived stem cells (AMSCs). In contrast, tumour formation was observed when canine AMSCs were utilized. These findings suggested that feline and human, but not canine, AMSCs are suitable for cell transplantation trials. This study aimed to further evaluate the feasibility of utilizing canine AMSCs for transplantation purposes as well as for felines. We
ABSTRACT. Distemper disease is an infectious disease reported in several species of domestic and wild carnivores. The high mortality rate of animals infected with canine distemper virus (CDV) treated with currently available therapies has driven the study of new efficacious treatments. Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic option for many degenerative, hereditary, and inflammatory diseases. Therefore, the aim of this study was to characterize stem cells derived from the canine fetal olfactory epithelium and to assess the systemic response of animals infected with CDV to symptomatic therapy and treatment with MSCs. Eight domestic mongrel dogs (N = 8) were divided into two groups: support group (SG) (N = 5) and support group + cell therapy (SGCT) (N = 3), which were monitored over 15 days. Blood samples were collected on days 0, 6, 9, 12, and 15 to assess blood count and serum biochemistry (urea, creatinine, alanine transferase, alkaline phosphatase, gammaglutamyl transferase, total protein, albumin, and globulin), and urine samples were obtained on days 0 and 15 for urinary evaluation (urine I). The results showed a high mortality rate (SG = 4 and SGCT = 2), providing inadequate data on the clinical course of CDV infection. MSC therapy resulted in no significant improvement when administered during the acute phase of canine distemper disease, and a prevalence of animals with high mortality rate was found in both groups due to the severity of symptoms.
Pesq. Vet. Bras. 34(12):1265-1270, dezembro 2014 1265 RESUMO.-[Análise cinemática da marcha de cães Golden Retriever saudáveis.] A análise cinemática relaciona--se com o movimento relativo entre corpos rígidos e encontra aplicação na análise da marcha e de outros movimentos do corpo. A interpretação de seus dados, quando há alteração, determina a escolha do tratamento a ser instituído. O objetivo deste estudo foi padronizar a marcha do cão Golden Retriever saudável visando auxiliar no diagnóstico e tratamento de afecções músculo esquelética. Neste estudo utilizou-se um sistema de análise cinemática para analisar a marcha de sete cães da raça Golden Retriever, fêmeas, idade entre 2 e 4 anos, peso variando de 21.5 a 28 kg, clinicamente sadias. Dados morfométricos foram coletados para descrever a população estudada. Variáveis de tempo e distâncias foram mensuradas para descrever a marcha, movimentos de flexão e extensão foram descritos para as articulações do ombro, cubital, cárpica, do quadril, femorotibial e társica. A marcha foi caracterizada lateral e teve hipótese de normalidade aceita para todas as variáveis, exceto para o apoio de quadril e apoio de cúbito, considerando um grau de confiança de 95%, ou seja, nível de significância α = 0.05. As variações foram atribuídas ao deslocamento das tarjas durante o movimento e ao repetido número de avaliações. A análise cinemática provou ser um consistente método de avaliação do movimento durante a marcha canina e os dados obtidos podem ser utilizados no diagnóstico e na comparação em avaliações de marcha para outros estudos e tratamento de cães com afecções musculoesqueléticas. Kinematic analysis relates to the relative movement between rigid bodies and finds application in gait analysis and other body movements, interpretation of their data when there is change, determines the choice of treatment to be instituted. The objective of this study was to standardize the march of Dog Golden Retriever Healthy to assist in the diagnosis and treatment of musculoskeletal disorders. We used a kinematic analysis system to analyse the gait of seven dogs Golden Retriever, female, aged between 2 and 4 years, weighing 21.5 to 28 kg, clinically normal. Flexion and extension were described for shoulder, elbow, carpal, hip, femorotibialis and tarsal joints. The gait was characterized lateral and had accepted hypothesis of normality for all variables, except for the stance of hip and elbow, considering a confidence level of 95%, significance level α = 0.05. Variations have been attributed to displacement of the stripes during movement and the duplicated number of reviews. The kinematic analysis proved to be a consistent method of evaluation of the movement during canine gait and the data can be used in the diagnosis and evaluation of canine gait in comparison to other studies and treatment of dogs with musculoskeletal disorders. Kinematic gait analyses in healthy Golden
