Coagulation and platelet adhesion-inducing factor in the endothelium of the retinal vessels.

By means of an immunofluorescent technique, we found factors promoting blood coagulation and platelet adhesion in the intima of retinal vessels. These factors coexisted with other agents causing the opposite process, fibrin dissolution. The components of this vascular hemostatic balance are possibly involved in the thrombotic occlusion of the retinal vessels, their canalization, and in the pathogenesis of diabetic retinopathy.

Von Willebrand's disease.

The common inheritable hemorrhagic disorder, von Willebrand's disease, has been known for only about 50 yr. During these years it has been well established that the cause of the disease is a deficiency of a plasma protein with remarkable biological properties. Future research should focus on details of the molecular structure of this protein. It is hoped that basic science will help to elucidate those aspects of von Willebrand's disease that are not yet properly understood.

Intravascular coagulation in pregnancy--treatment with heparin.

Two pregnant women with a history of miscarriages or premature labour are described. In the 25-27th week of pregnancy routine examinations showed high levels of FDP in serum. Subsequent extensive coaggulation studies revealed a positive ethanol gelation test, low levels of firbrinogen, plasminogen, alpha2-macroglobulin and P&P and high level of AHF related protein for the stage of pregnancy, i.e. finding indicating abnormal proteolysis with activation of the coagulation and fibrinolytic system. Continuous intravenous heparin treatment caused the coagulation system to return to normal throughout the rest of pregnancy. Both women gave birth to healthy babies without any complications. But the placenta showed numerous infarcts. The heparin treatment may have prevented later developing of placental dysfunction.

Genetic variants of von Willebrand's disease.

A specific antiserum against an antihaemophilic factor (AHF)-related plasma protein was raised in rabbits. A quantitative immunochemical method was used to determine the amount of this protein present in the plasma of 33 patients with haemophilia A and 70 patients with von Willebrand's disease. The protein probably consisted of AHF residing in or complexed with the von Willebrand factor. The patients with von Willebrand's disease were shown to fall into two separate genetic groups, one with decreased and one with normal amounts of the AHF-related protein. The patients with haemophilia A had normal amounts of the protein in their plasma.
