SummaryAttempts were made to demonstrate ultrastructural changes of the tissue thromboplastin after intravenous injection, as a model experiment on the pulmonary microthrombi formation induced by the tissue thromboplastin circulating from venous return.Concentrically arranged membrane structures of the injected thromboplastin disappeared in extremely short time after the injection of the thromboplastin in rabbits. The long sheet membrane of the injected thromboplastin was frequently seen as adhered to the vascular endothelium or to the surface of blood corpuscles. Furthermore, fibrin fibres were formed in contact with the long sheet membrane of the thromboplastin. Membrane structures were not found anywhere in the control rabbits.

Sinus venosus atrial septal defect (ASD) is usually associated with partial anomalous pulmonary venous return (PAPVR) of the right pulmonary veins to the superior vena cava (SVC), or to the SVC-right atrial junction. Standard procedure for repair of this defect is a patch roofing of the sinus venosus ASD and rerouting of pulmonary veins. However, the presence of SVC stenosis is a complication of this technique, and SVC augmentation is necessary in some cases. We present a simple technique for concomitant closure of sinus venosus ASD associated with PAPVR and augmentation of the SVC with a single autologous pericardial patch.

The blood system transports nutrients, oxygen, carbon dioxide and nitrogenous wastes; other functions include defence. Fish have a closed, single circulation in which blood is pumped by a contractile heart via a ventral aorta to the gills, then via the dorsal aorta to vessels supplying the tissues and organs, with a venous return to the heart. Large venous sinuses occur in elasmobranchs. Air-breathing fish have modifications of the circulation. Complex networks of narrow blood vessels can occur as red patches, retia, maximizing transfer of nutrients, oxygen or heat. Most fish have nucleated red blood cells (erythrocytes) with haemoglobin. The types of white blood cells (leucocytes) are similar to those of other vertebrates but there are thrombocytes rather than platelets. Nutrient transport is in the plasma, the fluid component of the blood, which may also carry antifreeze agents and molecules (e.g. urea in elasmobranchs) which counteract deleterious osmotic effects
