A reduced priming system.

Cardiopulmonary bypass (CPB), an integral part of valve surgery, is known to cause hemodilution, which can lead to a need for blood transfusion as well as a systemic inflammatory reaction. Our aim was to evaluate a reduced priming (RP) system for CPB with regard to clinical outcomes in patients undergoing valve surgery. Eleven patients were assigned to the new system with an RP volume. The RP system allowed for reduced hemodilution and a possible reduction in the necessity for blood transfusions.

Large saphenous vein graft aneurysm with a fistula to the right atrium.

We report on a case of a 65-year-old man who was admitted for anterior chest pain on effort. He had received coronary artery bypass grafting (CABG) surgery 20 years ago with saphenous vein grafts (SVGs) to the left anterior descending artery (LAD) and right coronary artery (RCA). An angiography demonstrated large aneurysmal dilatation of both grafts and a fistulous communication between the middle portion of the right SVG and the right atrium (RA). The aneurysm was excised surgically, and the fistula was closed with the right atrial wall with additional bypass grafts of the left internal thoracic artery (LITA) and gastroepiploic artery (GEA).

Total DNA preparation excluding extracellular acidic polysaccharide from Lipomyces yeasts and its application to taxonomic studies.

A preparation method of total DNA from Lipomyces yeasts was improved in order to exclude extracellular acidic polysaccharide thoroughly. The method combined an ultracentrifuge and polyethylene glycol precipitation with the usual method. The total DNAs obtained were analyzed for G + C content and by DNA-DNA hybridization. The results all agreed almost completely with literature data. All the DNA samples prepared using this method were pure enough for these taxonomic analyses and could also be used as templates of PCR for amplification of small subunit ribosomal DNA and the internal transcribed spacer region.
