Recent evidence suggests that oxygen free radicals may partially mediate irreversible ischemia-reperfusion injury in the myocardium. In the present study, the effect of a combination of two oxygen free radical scavengers, superoxide dismutase plus catalase (SOD + CAT), on the recovery of subendocardial segment function following 15 min of coronary artery(More)
The effect of the new antianginal drug, nicorandil, was studied in several models of myocardial ischemia in anesthetized dogs. In animals subjected to an acute or chronic coronary artery occlusion, nicorandil produced increases in collateral perfusion when changes in aortic pressure were minimized. In a model of irreversible ischemia, nicorandil produced a(More)
OBJECTIVES To test the hypothesis that L-659,066, a peripherally acting alpha 2-adrenoceptor agonist, will abolish the early pressor response but preserve the late depressor action of intravenous dexmedetomidine in conscious, unsedated dogs. DESIGN A prospective investigation. SETTING A laboratory research. PARTICIPANTS Nine chronically instrumented(More)
Brief (15-minute) coronary occlusion and subsequent reperfusion lead to prolonged functional and metabolic abnormalities (stunned myocardium). Previous work suggests that one factor responsible for this phenomenon is oxygen-derived free radicals. The formation of the highly reactive hydroxyl radical requires the presence of metal ions, most importantly(More)
The effect of the prostacyclin-mimetic, iloprost, on the reversibly damaged ("stunned") myocardium was studied in barbital-anesthetized, open-chest dogs subjected to 15 minutes of coronary artery occlusion and 3 hours of reperfusion. Regional myocardial segment shortening (%SS) was measured in the subendocardium of nonischemic and ischemic-reperfused areas(More)
BACKGROUND AND OBJECTIVES Continuous epidural analgesia has been used with increasing frequency to provide postoperative pain relief for children. Epidural space infection is a potential complication of epidural catheter placement. This study investigated the incidence of bacterial colonization on lumbar and caudal epidural catheter tips in postoperative(More)
BACKGROUND AND OBJECTIVES Nissen fundoplication is a common procedure in high-risk pediatric patients. This cohort study evaluated the influence of epidural versus intravenous opioid analgesia on the postoperative course of infants and children undergoing fundoplication. METHODS A retrospective review was made of the perioperative courses of 155(More)
The effects of a new intracellular calcium antagonist, KT-362 (150 and 300 micrograms/kg per min), on hemodynamics and collateral function (retrograde pressure and flow, radioactive microspheres) distal to an acute coronary artery occlusion were studied in anesthetized dogs and compared with the effects of the structurally related classical calcium channel(More)
The effects of acute treatment with delta 9-tetrahydrocannabinol (delta 9-THC) on serum levels of thyrotropin (TSH) and the thyroid hormones triiodothyronine (T3) and thyroxine (T4) were determined in the rat. Intraperitoneal doses of delta 9-THC greater than 3 mg/kg reduced serum TSH levels to less than 10% of control. The ED50 for delta 9-THC was(More)
The effects of a new intracellular calcium antagonist, KT-362 (5-[3-[[2-(3,4-dimethoxyphenyl)-ethyl]amino]-1-oxopropyl]- 2,3,4,5,-tetrahydro-1,5-benzothiazepine fumarate) on myocardial infarct size following a 90-min occlusion and 3-h reperfusion of the left anterior descending coronary artery (LAD) were determined in anesthetized dogs. Regional myocardial(More)
