[Initial aspects of the changes in diabetic proteinuria].

Proteinuria was analysed quantitatively and qualitatively in 156 diabetics and 63 matched controls. The study was limited to patients with a proteinuria of less than 100 ng/min in the recumbency. The urinary proteins were analysed using cellulose acetate electrophoresis, immunoelectrophoresis and sodium dodecylsulfate poly-acrylamide gel electrophoresis.

Tricuspid atresia, hypoplastic right ventricle, intact ventricular septum and congenital absence of the pulmonary valve.

A case of tricuspid atresia by sealing of the valves, associated with an intact ventricular septum, a hypoplastic right ventricle and the absence of the pulmonary valve, is described. The foramen ovale and the ductus arteriosus were widely patent but there was no interventricular communication. The pulmonary flow was assured by the ductus which had a saccular continuation in the pulmonary trunk.

Glomerular fibrinolytic activity after thrombin perfusion in the rat.

The effects of thrombin perfusion on glomerular fibrinolytic activity (GFA) have been assessed quantitatively in isolated rat glomeruli. Gfa was augmented by increasing total thrombin perfused to a maximal dose of 120 units per 100 gm. Fifty per cent maximal GFA occurred at a dose of 38 to 42 units of thrombin per 100 gm.
