modelos experimentales, diabetes, aloxana, estreptozotocina, hiperglucemiaResumen
Para el estudio de la diabetes se dispone de diversas estrategias metodológicas en modelos animales, tales como, técnicas quirúrgicas, modificaciones dietéticas, incluso manipulación genética y la administración de fármacos específicos, por su toxicidad. En animales, la diabetes experimental se logra con el uso de fármacos, como la aloxana o la estreptozotocina, los cuales producen daño irreversible en las células-pancreáticas, aunque causan una alta mortalidad, debido a la cetosis asociada al daño agudo de estas células pancreáticas. El objetivo de este trabajo fue analizar los protocolos farmacológicos y otras estrategias disponibles, para determinar si la diabetes experimental realmente emula la diabetes humana. La diabetes es un proceso progresivo y crónico, en el que la mayor parte de las alteraciones clínicas son consecuencia, en el largo plazo, de alteraciones micro y macrovasculares. Por ello, es conveniente diferenciar entre los efectos de una hiperglucemia aguda, con aquellos que se observan cuando la hiperglucemia se prolonga a lo largo del tiempo, a fin de establecer analogías, entre el modelo experimental animal, con el síndrome diabético humano, mediante datos de laboratorio y de tipo clínico, de uso habitual en el diagnóstico y manejo de la diabetes humana.
