ABSTRACT

Se aislaron cepas de Staphylococcus aureus resistentes a penicilina y productoras de ß-lactamasas. Mediante el método de dilución en tubos, se calculó la concentración inhibitoria CIM para amoxicilina-sulbactam, con diferente tensión de oxígeno y frente a heparina. Los valores de CIM se redujeron significativamente al sumar sulbactam al antibiótico. La disminución del oxígeno no afectó la capacidad inhibidora de ß-lactamasas del sulbactam, del mismo modo que la presencia de heparina no interfirió en su efecto protector sobre la amoxicilina. Estos resultados reafirmaron el concepto de efectividad de la combinación amoxicilina-sulbactam sobre los procesos infecciosos a S. aureus productores de ß-lactamasas, aun en afecciones donde se genera anaerobiosis relativa y también en enfermos con tratamiento simultáneo con heparina

ABSTRACT

La apendicitis aguda representa el 55 por ciento de las emergencias quirúrgicas operadas en el hospital de Apoyo Cayetano Heredia, y el 60 por ciento de estas son intervenidos en estados complicados. En un primer período de 1970*1975 la técnica se basó en la extirpación del órgano a través de incisiones verticales, con colocación de amplios drenajes y cierre primario de la herida, las que tuvieron como resultado un 38 por ciento de abscesos residuales, un tiempo promedio de hospitalización de 19 días y una mortalidad de 15 por ciento. A partir de 1975 se propuso el cambio radical de esta técnica quirúrgica mediante incisiones transversas, apendicectomías * a muñón libre, cierre diferido de la herida operatoria por segunda a tercera intención en peritonitis, lavado exhaustivo de cavidad y aplicación de drenajes sólo en los casos de peritonitis localizada (abscesos); los resultados obtenidos muestran una reducción al 2 por ciento de abscesos residuales, un tiempo de hospitalización de 7 días y una mortalidad de 1 por ciento (p<0.001). Esta experiencia nos demuestra la efectividad de la técnica quirúrgica propuesta al haber reducido significativamente la morbi*mortalidad, que se traducen en un menor tiempo de hospitalización optimizando la cama hospitalaria y recuperando rápidamente al paciente

ABSTRACT

The correlation between muscle glycogen content and physical performance in mice was evaluated by investigating whether an increase in glycogen content in skeletal muscle with insulin administration can improve the physical performance without other effects of exercise. Albino rats(group I) were divided into two groups, i.e., insulin and saline administered group. The former experimental group was treated with protamine zinc insulin(15U/kg/day) subcutaneously for two weeks to increase the content of the muscle glycogen and the latter control group with saline. Mice (group II) were also divided into insulin treated and control groups and both groups were subjected to running exercise on an animal treadmill up to point of exhaustion once every day. After two weeks of insulin treatment, the muscle glycogen content, the maximal running time and the maximal swimming time were measured in non-exercised group I. In group II, after 12 days of insulin and saline administration, the muscle glycogen content, the maximal running time, concentrations of lactate and pyruvate in the blood were measured before and after the maximal exhaustive running. The results were summarized as follows. In group I, the muscle glycogen content, the maximal running time and the maximal swimming time of the insulin administered group were significantly greater of the control groups. In group II, the maximal running time was significantly greater(P < 0.01) in the experimental group than of the control group, while the muscle glycogen content revealed no significant difference between the two groups. On the other hand, lactate concentration and lactate/pyruvate ratios in the blood were significantly lower in the experimental group than those of the control groups. From the above results, it may be concluded that the elevation of muscle glycogen content alone by insulin treatment without any previous physical training can improve physical performance of rats. And insulin was also found to improve physical performance even in experimental animals which had been subjected to a longterm of exercise.
