OBJECTIVE To evaluate the effect of low doses of warfarin in patients with systemic sclerosis with disseminated subcutaneous calcinosis. METHODS Three patients with disseminated subcutaneous calcinosis were treated with low doses of warfarin for 1 year. Subcutaneous calcinotic lesions, coagulation blood parameters, and the tendency for bleeding were followed up during the year. RESULTS Two ...

The present study was to assess the effect of storage conditions on prothrombin time (PT), activated partial thromboplastin time (aPTT) and fibrinogen concentration in blood samples of healthy dogs. Thirty-five dogs of various breeds were included in the study. Citrated blood samples were obtained and plasma was divided into four aliquots to assess selected clotting parameters by means of a coa...

In 45 patients with diabetes mellitus (DM) without cerebro-cardiovascular diseases (CCVD) the modified method of the tissue thromboplastin inhibition test (TTIT) was studied. TTIT is the method of detection of the lupus anticoagulant (LA), LA, first recognized in patients with systemic lupus erythematosus, is presented by a prolonged activated partial thromboplastin time (APTT), a slightly to m...

We describe here a test for lupus anticoagulants based on a modified Russell viper venom time (RVVT). using limiting amounts of phospholipid and venom. We have studied 29 patients with a prolonged dilute RVVT. Five of the 29 had a normal activated partial thromboplastin time and three of 1 4 tested by the tissue thromboplastin inhibition test were normal. In 1 7 of 1 9 patients tested. the dilu...
