Simultaneous platelet and fibrinogen survival with 75Se selenomethionine was determined in eight patients with acute infectious hepatitis of intermediate severity. Fibrinogen survival alone was estimated in another nine patients, seven of whom were receiving heparin treatment. Platelet survival was found to be normal (7-9 days) in seven of the 8 patients; it was reduced 4,6 days) only in one patient, who was also affected by measles. Fibrinogen survival was markedly reduced (1-3.7 days) and fibrinogen turnover sharply increased (0.59-2.80 mg/ml/day) in all but one patient, who had
thalassaemia
major, with normal fibrinogen survival and fibrinogen turnover. Heparin treatment did not affect either platelet survival or fibrinogen turnover. In all patients the coagulation defect was mild and no sign of disseminated intravascular coagulation or of increased fibrinolytic activity could be demonstrated by routine tests. These results are consistent with the hypothesis that in acute infectious hepatitis the decreased survival and increased turnover of fibrinogen might be due to a pathological pathway of defibrination in dependent of thrombin of
plasmin

Matriptase-2 plays a pivotal role in keeping iron concentrations within a narrow physiological range in humans. The opportunity to reduce matriptase-2 proteolytic activity may open a novel possibility to treat iron overload diseases, such as hereditary hemochromatosis and
thalassemia
. Here, we present 23 new analogues of trypsin inhibitor SFTI-1 designed to inhibit human matriptase-2. Influence of the modifications Gly1Lys, Ile10Arg, and Phe12His, as well as the introduction of Narg in P1 or P1 and P4 positions were examined. Selected peptides were further analyzed, together with previously reported peptides, for their inhibitory activity against related human proteases, that are, matriptase-1,
plasmin
, thrombin and trypsin. A highly potent inhibitor of matriptase-2, the bicycylic [Arg
