dc.description.abstractSe discuten las expresiones de actividad enzimatica mas utilizadas en estudios comparados de actividad en diferentes tejidos: microkatales por unidad de peso del tejido, por unidad de peso de proteina y por unidad de peso de AON. Se utiliza tambien la expresi6n de microkatales presentes en un 6rgano determinado referidos a unidad de peso del animal, 100 g en el caso de la rata. Las diversas expresiones se han aplicado a los niveles de aspartato transaminasa, glutamato deshidrogenasa y AMP desaminasa en higado, musculo estriado de pata trasera y riiiones de rata adulta. De Ios datos presentados se concluye que las mediciones de actividades enzimaticas en tejidos deben ser expresadas en mas de una forma, ya que la informaci6n obtenida a partir de una sola de ellas puede ser substancialmente distinta de la obtenida con otra de ellas, dando lugar a posibles conclusiones err6neas de! papel metab6lico jugado por el enzima en un tejido determinado.es_ES
dc.description.abstractThe widely used activity expressions for enzyme levels in tissues are discussed: microkatals per unit of tissue weight, protein weight, and DNA weight. The expression of microkatals present in a definite organ in reference to a standard animal weight, 100 g in the case of rat, is also used. The different expressions are applied to aspartate transaminase, glutamate dehydrogenase and AMP deaminase activities in liver, hind leg striated muscle and kidneys in rat. The conclusion is reached that measurements of enzyme activity in tissues should be expressed in more than one form, as the information drawn from one could differ substantially from that obtained from other, giving artifactual views of the metabolic role played by the enzyme in a given tissue.en_EN
