We tested the hypothesis that glucose-insulin-potassium (GIK)-induced protection against myocardial infarction depends on ATP-dependent K+ (KATP) channel activation and is abolished by hyperglycemia before the ischemia. Dogs were subjected to a 60-min coronary artery occlusion and 3-h reperfusion in the absence or presence of GIK (25% dextrose; 50 IU insulin/l; 80 mM/l KCl infused at 1.5 ml·kg−1·h−1) beginning 75 min before coronary artery occlusion or 5 min before reperfusion. The role of KATP channels was evaluated by pretreatment with glyburide (0.1 mg/kg). The efficacy of GIK was investigated with increases in blood …

Alteraciones Oculares En Diabetes, Hernández-Rodríguez Patricia, Quintero Gladys, Ingrid Jiménez

Ciencia y Tecnología para la Salud Visual y Ocular

Muchas alteraciones oculares son ocasionadas por los cambios bioquímicos generados en la Diabetes. La diabetes es una entidad patológica con múltiples complicaciones, siendo el daño ocular una de las más importantes, ya que se presentan problemas visuales y retinopatía. Aproximadamente el 25% de los diabéticos generen ceguera por alteraciones en retina lo que ocasiona discapacidad en los pacientes y disminuye su calidad de vida. La retinopatía es característica de personas con diabetes tipo 1 y 2, según estudios realizados por Dinneen S et al, 1998 en Estados Unidos es la causa principal de ceguera en adultos. En Colombia no se …
