ABSTRACT

We evaluated the role of oxygen free radicals in the induction of acute stress gastric ulcer in rats. After 12 hr of inmobility, ulcers of up to 4 mm were observed in the gastric mucosa. Pretreatment with allopurinol, a xantine oxydase inhibitor, produced a significant reduction in the number and size of lesions (p < 0.0001). No protection was afforded by aluminum hydroxyde or ranitidine alone, but enhanced protection was observed when given in association to allopurinol. A secondary role for H ions is suggested by these findings. Our results support the hypothesis of a role of a oxygen free radicals in the pathogenesis of stress gastric ulcers. Allopurinol might be used in conditions prodisposing to stress in patients

ABSTRACT

Se realiza un estudio de los niños accidentados atendidos en el Servicio de Urgencia del Hospital de Collipulli (tipo IV) entre los años 1981-1985. En el material analizado se aprecia un predominio del sexo masculino (64%); la procedencia urbana (73%) y de las consultas entre 9.000 y 16.000 horas. No hay diferencias significativas en la frecuencia de los accidentes de los niños de 0 a 5 años; 6 a 10 años y 11 a 15 años. Tampoca hay variaciones estacionales apreciables. Los accidentes más frecuentes atendidos fueron heridas y contusiones (47%); mordeduras de animales (14%); quemaduras (12%); fracturas, luxaciones y esguinces (95) y picaduras de insectos (6%). El 84% de los casos se resolvieron ambulatoriamente; el 12% requirió hospitalización y sólo el 4% debió derivarse a Centros de mayor complejidad
