ABSTRACT

BACKGROUND & OBJECTIVE: There is evidence that reactive oxygen species (ROS) plays an important role in the pathophysiology of many paediatric disorders. We carried out this study to see whether superoxide dismutase (SOD) activity was associated with age, sex and rural or urban status in three groups of Spanish people (newborns, children and young). METHODS: SOD activity was measured in red blood cells in newborns, children and young Spanish people (n=1212, divided in six groups) using the Minami and Yoshikawa method. RESULTS: The newborns had high levels of SOD activity, but among all age groups studied, SOD showed the highest activity in groups 1 and 2. We also observed that this activity decreased gradually with age until achieving adult levels. No significant variations with respect to sex were detected, except for the >or=14 to 18 yr age group, in which SOD activity decreased significantly in females. INTERPRETATION & CONCLUSION: Our findings show that SOD activity in newborns, children and young Spanish people is affected by age but not by gender (except from >or=14-18 yr) or rural or urban status.

ABSTRACT

Se han determinado los niveles de superóxido dismutasa (SOD) y catalasa (CAT) en 420 individuos de uno y otro sexo y edades comprendidas entre 50 y 93 años. De ellos, 126 que no mostraban ninguna enfermedad relevante se utilizaron como grupo control. Los 294 restantes mostraban diferentes trastornos: alteraciones del sistema vascular (insuficiencias coronarias, hipertensión, infarto, etc.), alteraciones del sistema osteoarticular (artritis, polialtralgias, osteoporosis, etc.), miomas, afecciones, prostáticas, enfermedad pulmonar obstructiva crónica (EPOC) y accidente cerebral vascular agudo (ACVA). Para valorar SOD se utilizó el método de minami y Yoshikawa y el método de Aebi para valorar CAT. Métodos estadísticos: ANOVA y "t" de Student. En la población control se han obtenido: 1) niveles de SOD y CAT más elevados en mujeres que en varones. 2) la actividad de CAT disminuye con la edad. En la población con patologías: 3) la actividad de SOD está elevada en cardiovascular, miomas, EPOC y ACVA. 4) la actividad de CAT desciende en cardiovascular, próstata, EPOC y ACVA. 5) en osteoarticular actividad normal de SOD y CAT, aunque SOD desciende con la edad, CAT desciende con la edad en cardiovascular y EPOC. En general el comportamiento de ambos enzimas tiende a conseguir un equilibrio en el sistema antioxidante
