The effect of amoxycillin and doxycyciine on human granulocyte function was studied in vitro. The antimicrobial agents were added to tests of chemotaxis, random motility, yeast phagocytosis, and killing, at progressing concentrations. The effect was also evaluated in vivo by measuring chemotaxis and random motiiity (agarose technique) of granulocytes from(More)
Between September 1979 and December 1982, 56 St Jude Medical valvular prostheses were implanted in 54 patients over 65 years of age. Surgery consisted in simple aortic valve replacement (35 cases), simple mitral valve replacement (12 cases), double aortic and mitral valve replacement (2 cases), valve replacement and coronary artery bypass surgery (3 cases),(More)
Myocardial infarction is almost always the consequence of a thrombotic obstruction of one or more coronary arteries. We report our experience with the first 24 cases of intracoronary thrombolysis for recanalization of obstructed coronary arteries. 19 cases were successful, 1 case was partially successful and in 4 instances no reopening was observed. The(More)
The time-lag between coronary occlusion and irreversible damage to the myocardium is ill-defined in man. In 10 patients the changes in left ventricular function have been studied after coronary occlusion during diagnostic or therapeutic cardiac catheterization of 1-2 hours' duration. Revascularization was achieved either surgically or through intracoronary(More)
Vasodilator therapy in congestive heart failure has proven an effective adjunct to conventional treatment with digitalis and diuretics. In this study dipyridamole was used in combination with isosorbide dinitrate to treat twelve patients (mean age 55 years) with idiopathic congestive cardiomyopathy. All patients were in N.Y.H.A. class III or IV and were(More)
The St. Jude Medical cardiac valve is a low-profile, bileaflet, central-flow prosthesis made of pyrolitic carbon. During a 39-month period (October 1, 1979 to December 31, 1982) a total of 169 St. Jude valves were implanted in 155 patients. While 141 patients received one valve, 95 in the aortic, 45 in the mitral and 1 in the tricuspid position, 14 patients(More)
