RESUMO

Estudios previos han demostrado que los bisfosfonatos son potentes inhibidores de la resorción ósea. El aceite de oliva (O) es rico en ácidos grasos monoinsaturados con potentes propiedades anti-oxidantes. El objetivo de este estudio fue estudiar el efecto del tratamiento de alendronato (AL) y pamidronato (PA) y de O sobre la regeneración tisular. Las fórmulas se dosificaron 0,5 mg/kg de peso para AL, y de 0,6 mg/kg de peso para PA. El O se administró en la dieta, 50 g/ Kg. Cincuenta y cuatro ratas macho de la línea Wistar se dividieron en 6 grupos. El grupo control (C), recibió semanalmente 0,3 ml/100g de peso corporal de solución salina vía subcutánea. El grupo (AL) recibió semanalmente por vía subcutánea en el miembro posterior izquierdo. El grupo (PA) se colocó igual que el grupo anterior. El grupo (O) fue tratado en la alimentación y en las áreas de la cirugía recibieron inyección subcutánea con solución fisiológica. El grupo (ALO) recibió tratamiento combinado con AL y O. El grupo (PAO) se trató igual al anterior. La cirugía consistió en una incisión longitudinal en las tibias realizando un defecto circular en la parte plana de cada tibia hasta llegar al hueso medular. Se tomaron radiografías a los 0, 7, 15, 30, 60 y 90 días y fueron analizadas con el Software Image Pro Plus. Los estudios estadísticos se realizaron a través del análisis de la variancia a dos y tres criterios de clasificación. Se evidencio un incremento en la densidad mineral ósea promedio (DMO) conforme avanza el tiempo en todos los grupos, siendo evidentes con PA a los 60 días. El tratamiento O mostró eficacia en la remodelación ósea, observándose un pico a los 60 días. Esto sugiere que O representa una opción terapéutica para el tratamiento de las patologías óseas.


Previous studies have shown that bisphosphonates are potent inhibitors of bone resorption. Olive oil (O) is rich in monounsaturated fatty acids with potent anti-oxidant properties. The objective of this work was to study the effect of alendronate treatment (AL) and pamidronate (PA) and O on tissue regeneration. Formulas 0.5 mg / kg for AL dosed, and 0.6 mg / kg for PA. O was administered in the diet, 50 g / kg. Fifty-four male rats Wistar were divided into 6 groups. The control group (C) received weekly 0.3 ml / 100g body weight of saline subcutaneously. The group (AL) received a weekly dose subcutaneously in the left posterior limb. The group (PA) was placed as the previous group. The group (O) was treated in food and in the areas of surgery received subcutaneousinjection with saline. The group (ALO) received combined treatment with Al and O. The group (PAO) was treated the same as before. Surgery consisted of a longitudinal incision in the warm using a circular on the flat side of each tibia until the medullary bone defect. X-rays at 0, 7, 15, 30, 60 and 90 days were taken and analyzed with Image Pro Plus Software. Statistical studies were conducted through analysis of variance to two and three classification criteria. Results: an increase in the average bone mineral density (BMD) was evident as time progresses in all groups, with PA still evident at 60 days. Or treatment showed efficacy in bone remodeling observed a peak at 60 days. Conclusions: This suggests that O represents a therapeutic option for the treatment of bone disease.

RESUMO

Widespread use of ultrasonography has resulted in an increase in the recognition of fetal hydronephrosis. The enthusiasm that accompanied early interventions has been tempered by the experience and results obtained over the past 2 decades. The goal has remained the same: to identify patients with serious prenatal obstruction and to identify those which may benefit from intervention. Myelomeningocele remains a devastating congenital anomaly. Fetal and experimental studies suggested that patients with myelomeningocele could benefit from prenatal intervention. Advances in technology and perinatal management have made intervention for more complex malformations such as myelomeningocele possible. This article will review current knowledge and will detail rational management for the management of prenatal hydronephrosis. The current state of antenatal myelomeningocele repair and the urologic implications will be described as well.
