Platelet aggregation in diabetic retinopathy was investigated in a group of 25 patients. An enhanced activity induced by epinephrine and arachidonic acid was found in this group as compared with the controls, whereas in adenosine diphosphate (ADP) platelet aggregation no differences were observed. Spontaneous aggregation was found in 8% of the diabetic retinopathy cases.

We found distinct alterations of the clotting and fibrinolytic mechanisms in a 27-year-old man who suffered from typical bilateral vasculitis, clinically and fluoroangiographically manifest as obstruction of the central retinal veins. The partial thromboplastin time was slightly increased, a partial clot lysis occurred after one hour, the plasminogen level was markedly low, and alpha2-macroglobulin was decreased, as were factor XII and IgG. Kallikrein was absent. Similar changes, though not so pronounced, were also found in the patient's son and in his brother.
A family with allergic manifestations, haemostatic disturbances, total absence of haemolytic activity of the complement system and low IgG levels is described. It is suggested that this functional abnormality of the complement system and the decreased level of immunoglobulin G may be due to immune complex reactions.

The fibrinolytic pathway and the protease inhibitors in 12 to 24-and 24-to 36-week-old fetuses were examined and compared with full-term newborns. The activity of the fibrinolytic system, as well as the values of the protease inhibitors approach the normal values progressively with the embryonic maturation.

Relationship between an inherited qualitative defect of the complement system and intrinsic asthma, and the direct participation of the kinin system in producing asthma, are reported. Qualitative complement impairment that produced hereditary angioedema in the son of an asthmatic father indicated that the kinin system was the vasoactive mediator in both cases.
We describe a surgical technique for reconstruction of the upper cervical esophagus after a segment has been excised. The technique involves the downward rotation of a full thickness pharyngeal flap to close the defect. The flap is obtained from the posterior wall of the hypopharynx and oropharynx. We describe a case in which this technique was used.
