OBJECTIVES To describe the incidence and management of haemolysis after transcatheter coil occlusion of the arterial duct. DESIGN Prospective clinical and echocardiographic follow up of patients who have undergone implantation of the Cook detachable duct occlusion coil. SETTING Tertiary paediatric cardiac centre. PATIENTS Five cases of haemolysis (two girls aged 6 and 11 months; three boy...

Severe haemolytic anaemia developed in a 33 year old patient after the mitral valve was replaced with a St Jude medical prosthesis. This was the patient's third thoracotomy. She had already had a mitral commissurotomy and a mitral valve bioprosthesis. The patient had an E+ antibody to red blood cells as well as a paraprosthetic leak. The haemolysis became less severe once the population of E+ r...

Human erythrocytes were exposed to high concentrations of methane and nitrogen through the application of elevated partial pressures of these gas molecules. Cell leakage (haemolysis) was measured for cells exposed to these gases under a wide range of experimental conditions. Application of methane produces haemolysis at pressures far below the hydrostatic pressures known to disrupt membrane or ...

The use of a single-radial-haemolysis technique for the detection of antibody to rubella virus is described. The single-radial-haemolysis test was compared with the standard HI methods for the detection of antibody to rubella virus. A close correlation between the two methods was observed in a survey of over two thousand serum samples and the study indicated that single-radial-haemolysis was hi...

Haemolysins of Salmonella are important due to their probable role in pathogenesis of systemic salmonellosis and use in sub-serovar level typing. The present study was undertaken to determine haemolytic potential of Salmonella Gallinarum strains through phenotypic and genotypic methods. Amplification of haemolysin gene (clyA) and cytolysin gene (slyA) was attempted in order to determine their r...
