In the present work, we compare the results of the traditional method, which uses gradient isolated lymphocytes as the source of cells for the culture and tritiated thymidine incorporation to measure proliferative response (LP- 3 H), with other two methods: culture of whole blood and proliferation measure with 3 H- thymidine (SE-3 H), and culture of isolated lymphocytes and proliferation evaluation with a colorimetric assay using MTT (LP-MTT). Blood samples of twelve adult, healthy dogs were processed by the three mentioned methods, using ConcanavalinA as mitogen and the Stimulation Index (SI) to express the degree of lymphoproliferation. The SI obtained by the SE-3 H method were significativily higher than those of the traditional test, while those obtained by the LP-MTT method were significativily lower. These results show that the SE3 H method could be a suitable alternative to evaluate the lymphoproliferation in our laboratory conditions; it is required more research to evaluate if, in spite of the lower SI, the LP-MTT method could be suitable to evaluate lymphoproliferation in dogs. Based on the results obtained in this\nexperience, we established a normal SI range for each method. Fil: Ramayo, L.G. Universidad de Buenos Aires. Facultad de Ciencias Veterinarias.

Mundo, S.L. 2005 La prueba de proliferación de linfocitos inducida por mitógenos in vitro se utiliza para evaluar la inmunidad celular. En el presente trabajo, se comparan los resultados obtenidos con el método tradicional, que utiliza linfocitos purificados para el cultivo y la captación de timidina tritiada como método de medición de la proliferación (LP- 3 H), con otras dos metodologías: el uso de sangre entera con revelado por captación de timidina tritiada (SE-3 H) y el uso de linfocitos purificados con revelado por ensayo colorimétrico con MTT (LP-MTT). Se trabajó sobre muestras de 12 caninos clínicamente sanos que fueron procesadas por las tres metodologías. Se utilizó Concanavalina A como mitógeno y el Indice de Estimulación (IE) como expresión de los resultados. El método de SE-3 H arrojó valores de IE significativamente mayores que la técnica clásica, por lo que resultaría útil para evaluar la proliferación linfocitaria en caninos en nuestras condiciones de trabajo. El método de LP-MTT mostró valores de IE significativamente menores, por lo que se requieren más estudios para evaluar su posible uso en la medición de la funcionalidad linfocitaria. Sobre la base de los resultados obtenidos se estableció un rango normal de valores de IE para cada método. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) inmunidad celular proliferación canino cellular immunity proliferation dog spa Universidad de Buenos Aires.
