Beta-adrenoceptor density and affinity, studied by H3-CGP 12177 binding, and adenylate cyclase activity were measured in 12 left ventricles of rabbits with heart failure and compared to 13 left ventricles of control (C) rabbits. Heart failure (HF) was induced by a double volume (aortic insufficiency) plus pressure (aortic stenosis 14 days later) overload.(More)
Heart failure is usually characterized by a relative insensitivity to atrial natriuretic factor (ANF). Downregulation of ANF receptors has been reported but remains controversial. Renal response to ANF infusion, glomerular ANF receptors, and guanosine 3',5'-cyclic monophosphate (cGMP) production have been studied in rabbits with congestive heart failure(More)
In a model of heart failure induced in rabbits by a double volume plus pressure overload, sarcoplasmic reticulum (SR) function was measured by Ca uptake and ryanodine receptor analysis. When expressed per mg of proteins, Ca uptake was decreased by 20% in failing hearts (FH) and ryanodine receptor density was similar in control hearts (CH) and in FH. However(More)
Beta-blockade has been shown to improve cardiac response to catecholamines in heart failure but cellular mechanisms of the improvement are unknown. The effect on left ventricular function of a 14 day propranolol treatment was studied in seven treated and eight non-treated rabbits with experimental heart failure. All animals were subjected to a volume(More)
Résumé La leucémie/lymphome à cellules T de l'adulte est une prolifération tumorale de cellules lymphoïdes T matures activées, dont l'agent étiologique est le rétrovirus humain T cell-leukemia virus type 1, ce virus entraine rarement des désordres inflammatoires bronchioloalveolaires. Nous rapportons l'observation d'un patient hospitalisé pour une(More)
Adult T-Cell Leukemia/Lymphoma is a tumoral proliferation of activated mature T lymphoid cells whose causative agent is a retrovirus known as Human T-cell leukemia virus type 1. This virus rarely causes inflammatory bronchioloalveolar disorders. We report the case of a patient hospitalized with diffuse interstitial lung disease and whose etiological(More)
Fusarium is a filamentous brown fungus found in soil, on plants and outdoors responsible for localized or disseminated infections. Diagnosis is based on blood cultures and skin biopsy. Disseminated fusariosis is a rare and serious fungal infection, that occurs especially in neutropenic immunosuppressed patients. Treatment is difficult and mortality is(More)
